The period from onset of one menstrual bleeding (MENSTRUATION) to the next in an ovulating woman or female primate. The menstrual cycle is regulated by endocrine interactions of the HYPOTHALAMUS; the PITUITARY GLAND; the ovaries; and the genital tract. The menstrual cycle is divided by OVULATION into two phases. Based on the endocrine status of the OVARY, there is a FOLLICULAR PHASE and a LUTEAL PHASE. Based on the response in the ENDOMETRIUM, the menstrual cycle is divided into a proliferative and a secretory phase.
The period of the MENSTRUAL CYCLE representing follicular growth, increase in ovarian estrogen (ESTROGENS) production, and epithelial proliferation of the ENDOMETRIUM. Follicular phase begins with the onset of MENSTRUATION and ends with OVULATION.
The periodic shedding of the ENDOMETRIUM and associated menstrual bleeding in the MENSTRUAL CYCLE of humans and primates. Menstruation is due to the decline in circulating PROGESTERONE, and occurs at the late LUTEAL PHASE when LUTEOLYSIS of the CORPUS LUTEUM takes place.
The period in the MENSTRUAL CYCLE that follows OVULATION, characterized by the development of CORPUS LUTEUM, increase in PROGESTERONE production by the OVARY and secretion by the glandular epithelium of the ENDOMETRIUM. The luteal phase begins with ovulation and ends with the onset of MENSTRUATION.
The complex series of phenomena, occurring between the end of one CELL DIVISION and the end of the next, by which cellular material is duplicated and then divided between two daughter cells. The cell cycle includes INTERPHASE, which includes G0 PHASE; G1 PHASE; S PHASE; and G2 PHASE, and CELL DIVISION PHASE.
The mucous membrane lining of the uterine cavity that is hormonally responsive during the MENSTRUAL CYCLE and PREGNANCY. The endometrium undergoes cyclic changes that characterize MENSTRUATION. After successful FERTILIZATION, it serves to sustain the developing embryo.
The major progestational steroid that is secreted primarily by the CORPUS LUTEUM and the PLACENTA. Progesterone acts on the UTERUS, the MAMMARY GLANDS and the BRAIN. It is required in EMBRYO IMPLANTATION; PREGNANCY maintenance, and the development of mammary tissue for MILK production. Progesterone, converted from PREGNENOLONE, also serves as an intermediate in the biosynthesis of GONADAL STEROID HORMONES and adrenal CORTICOSTEROIDS.
Variations of menstruation which may be indicative of disease.
A combination of distressing physical, psychologic, or behavioral changes that occur during the luteal phase of the menstrual cycle. Symptoms of PMS are diverse (such as pain, water-retention, anxiety, cravings, and depression) and they diminish markedly 2 or 3 days after the initiation of menses.

Painful menstruation.
A major gonadotropin secreted by the adenohypophysis (PITUITARY GLAND, ANTERIOR). Luteinizing hormone regulates steroid production by the interstitial cells of the TESTIS and the OVARY. The preovulatory LUTEINIZING HORMONE surge in females induces OVULATION, and subsequent LUTEINIZATION of the follicle. LUTEINIZING HORMONE consists of two noncovalently linked subunits, alpha and beta. Within a species, the alpha subunit is common in the three pituitary glycoprotein hormones (TSH, LH and FSH), but the beta subunit is unique and confers its biological specificity.
A major gonadotropin secreted by the adenohypophysis (PITUITARY GLAND, ANTERIOR). Follicle-stimulating hormone stimulates GAMETOGENESIS and the supporting cells such as the ovarian GRANULOSA CELLS, the testicular SERTOLI CELLS, and LEYDIG CELLS. FSH consists of two noncovalently linked subunits, alpha and beta. Within a species, the alpha subunit is common in the three pituitary glycoprotein hormones (TSH, LH, and FSH), but the beta subunit is unique and confers its biological specificity.
The period before MENOPAUSE. In premenopausal women, the climacteric transition from full sexual maturity to cessation of ovarian cycle takes place between the age of late thirty and early fifty.
The period in the MENSTRUAL CYCLE that is optimal for FERTILIZATION of the OVUM and yielding PREGNANCY. The duration of fertile period depends on the life span of male GAMETES within the female reproductive tract and the time of OVULATION. It usually begins a few days before ovulation and ends on the day of ovulation.

Absence of menstruation.
Method to determine the occurrence of OVULATION by direct or indirect means. Indirect methods examine the effects of PROGESTERONE on cervical mucus (CERVIX MUCUS), or basal body temperature. Direct ovulation detection, generally used in fertility treatment, involves analyses of circulating hormones in blood and ULTRASONOGRAPHY.
Personal care items used during MENSTRUATION.
Compounds that interact with ESTROGEN RECEPTORS in target tissues to bring about the effects similar to those of ESTRADIOL. Estrogens stimulate the female reproductive organs, and the development of secondary female SEX CHARACTERISTICS. Estrogenic chemicals include natural, synthetic, steroidal, or non-steroidal compounds.
The reproductive organ (GONADS) in female animals. In vertebrates, the ovary contains two functional parts: the OVARIAN FOLLICLE for the production of female germ cells (OOGENESIS); and the endocrine cells (GRANULOSA CELLS; THECA CELLS; and LUTEAL CELLS) for the production of ESTROGENS and PROGESTERONE.
Suspension or cessation of OVULATION in animals or humans with follicle-containing ovaries (OVARIAN FOLLICLE). Depending on the etiology, OVULATION may be induced with appropriate therapy.
The period of cyclic physiological and behavior changes in non-primate female mammals that exhibit ESTRUS. The estrous cycle generally consists of 4 or 5 distinct periods corresponding to the endocrine status (PROESTRUS; ESTRUS; METESTRUS; DIESTRUS; and ANESTRUS).

This family of proteins includes a wide variety of classes, including CYCLIN-DEPENDENT KINASES, mitogen-activated kinases, CYCLINS, and PHOSPHOPROTEIN PHOSPHATASES as well as their putative substrates such as chromatin-associated proteins, CYTOSKELETAL PROTEINS, and TRANSCRIPTION FACTORS.
An aromatized C18 steroid with a 3-hydroxyl group and a 17-ketone, a major mammalian estrogen. It is converted from ANDROSTENEDIONE directly, or from TESTOSTERONE via ESTRADIOL. In humans, it is produced primarily by the cyclic ovaries, PLACENTA, and the ADIPOSE TISSUE of men and postmenopausal women.
The yellow body derived from the ruptured OVARIAN FOLLICLE after OVULATION. The process of corpus luteum formation, LUTEINIZATION, is regulated by LUTEINIZING HORMONE.
Predicting the time of OVULATION can be achieved by measuring the preovulatory elevation of ESTRADIOL; LUTEINIZING HORMONE or other hormones in BLOOD or URINE. Accuracy of ovulation prediction depends on the completeness of the hormone profiles, and the ability to determine the preovulatory LH peak.
Chemical substances having a specific regulatory effect on the activity of a certain organ or organs. The term was originally applied to substances secreted by various ENDOCRINE GLANDS and transported in the bloodstream to the target organs. It is sometimes extended to include those substances that are not produced by the endocrine glands but that have similar effects.

Similar to the pituitary LUTEINIZING HORMONE in structure and function, chorionic gonadotropin is involved in maintaining the CORPUS LUTEUM during pregnancy. CG consists of two noncovalently linked subunits, alpha and beta. Within a species, the alpha subunit is virtually identical to the alpha subunits of the three pituitary glycoprotein hormones (TSH, LH, and FSH), but the beta subunit is unique and confers its biological specificity (CHORIONIC GONADOTROPIN, BETA SUBUNIT, HUMAN).
Glycoproteins that inhibit pituitary FOLLICLE STIMULATING HORMONE secretion. Inhibins are secreted by the Sertoli cells of the testes, the granulosa cells of the ovarian follicles, the placenta, and other tissues. Inhibins and ACTIVINS are modulators of FOLLICLE STIMULATING HORMONE secretions; both groups belong to the TGF-beta superfamily, as the TRANSFORMING GROWTH FACTOR BETA.

The smooth muscle coat of the uterus, which forms the main mass of the organ.
Hormones produced in the testis.
RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.

Regulatory signaling systems that control the progression through the CELL CYCLE. They ensure that the cell has completed, in the correct order and without mistakes, all the processes required to replicate the GENOME and CYTOPLASM, and divide them equally between two daughter cells. If cells sense they have not completed these processes or that the environment does not have the nutrients and growth hormones in place to proceed, then the cells are restrained (or "arrested") until the processes are completed and growth conditions are suitable.

Novel insights into human endometrial paracrinology and embryo-maternal communication by intrauterine microdialysis. (1/1799)

The regulation of human implantation is still unknown. Evidence from mice suggests an essential role for several paracrine mediators but species differences with implantation in the human preclude the extrapolation of these concepts to humans. An intrauterine microdialysis device (IUMD), consisting of microdialysis tubing glued into a balloon catheter on one side and into a polypropylene tube on the other, allows a dynamic and accurate in-vivo measurement of uterine paracrine interactions in humans. Inserted into the uterine cavity in the form of a loop, it can be continuously perfused with saline to reveal a number of relevant cytokines and growth factors in uterine effluents of non-pregnant women in both follicular and luteal phases. These included interleukin (IL)-1alpha, IL-1beta, IL-6, leukaemia inhibitory factor (LIF), macrophage colony-stimulating factor (M-CSF), epidermal growth factor, vascular endothelial growth factor (VEGF), insulin-like growth factor binding protein-1 (IGFBP-1), prolactin, and human chorionic gonadotrophin (HCG). The source of intrauterine HCG is unclear since endometrial mRNA for the HCG beta-subunit is not revealed using reverse transcriptase polymerase chain reaction analysis. Applying urinary HCG locally via the IUMD profoundly alters endometrial secretory parameters. Prolactin, IGFBP-1, and M-CSF are significantly inhibited and VEGF is regulated in a biphasic manner involving early stimulation followed by inhibition of intrauterine levels. Use of the IUMD has thus shown that the urinary HCG preparations routinely used for ovulation induction and luteal support may directly alter endometrial function.  (+info)

Marker molecules of human endometrial differentiation can be hormonally regulated under in-vitro conditions as in-vivo. (2/1799)

An established cell culture system of isolated human endometrial stromal and epithelial cells has been used to study the effects of oestrogen and progesterone, as well as their antagonists, upon endometrial cells. Normal hormonal regulation in vivo was investigated simultaneously in endometrial tissue samples taken at different phases of the menstrual cycle. Several marker molecules analysed by immunohistochemistry appeared to depend strongly on endocrine regulation and could be traced in culture. Immunohistochemically, basic parameters of cell biology were identified in vitro, e.g. cell proliferation (Ki-67), adhesion molecules (beta3 integrin) and paracrine factors (leukaemia inhibitory factor). The most reliable parameters to assess hormonal influences were oestrogen and progesterone receptor molecules. Immunohistochemical localization could be improved by molecular biological analysis using RT-PCR. In the presence of oestrogen, a significant expression of hormone receptors was also shown by RT-PCR, and withdrawal of oestrogens and addition of gestagen, i.e. medroxyprogesterone acetate, caused receptor downregulation. Addition of the anti-oestrogen ICI 182.780 to cell-culture medium significantly decreased the synthesis of progesterone receptors.  (+info)

Utero-ovarian interaction in the regulation of reproductive function. (3/1799)

The physiological regulation of fertile reproductive cycle in mammals depends on interactions between hypothalamus-pituitary, ovarian and uterine stimuli. Over the past 20 years, much has been learned about the interrelation between the affluent and effluent lymph and vascular drainage in and around both ovarian and uterine tissues. An essential feature in the regulation of the fertile cycle is the functional status of the ovary, particularly the corpus luteum. During the time of implantation and the early pregnancy, an active corpus luteum is essential. As human chorionic gonadotrophin (HCG) is important in the maintenance of the corpus luteum, we investigated if it was produced by the cyclic endometrium. Immunohistochemical and in-situ hybridization reactions were performed but neither identified the presence of HCG during the proliferative phase. Positive staining and beta-human chorionic gonadotrophin (beta-HCG) mRNA were observed during the secretory phase in the glandular cells of the endometrium. The results were confirmed by Western blotting of secretory phase endometrium extracts and assessment of the functional secretory capacity of primary endometrial cultures. Polymerase chain reaction (PCR) investigations showed a positive result in the secretory phase. We postulate that, based on the very close morphological interrelation between the uterus and the ovary, the beta-HCG of the endometrium is the primary factor for the maintenance of the corpus luteum and early pregnancy.  (+info)

Endometrial oestrogen and progesterone receptors and their relationship to sonographic appearance of the endometrium. (4/1799)

The rapid development of ultrasonographic equipment now permits instantaneous assessment of follicles and endometrium. The sonographic appearance of the endometrium has been discussed in relation to in-vitro fertilization (IVF) cycles. However, a generally agreed view of the relationship of the sonographic appearance to fecundity in IVF cycles has not emerged. We have studied the relationship between steroid receptors and the sonographic appearance of the preovulatory endometrium in natural cycles and ovulation induction cycles. Preovulatory endometrial thickness was not found to be indicative of fecundity, although a preovulatory endometrial thickness of <9 mm related to an elevated miscarriage rate. The preovulatory endometrial echo pattern did not predict fecundity. No relationships were found among endometrial appearance, endometrial steroid receptors and steroid hormone concentrations in serum. Oestrogen or progesterone receptor concentrations were not related to endometrial thickness or to concentrations of serum oestradiol, the only significant correlation being found between the endometrial concentrations of oestrogen and progesterone receptors. The ratio of progesterone:oestrogen receptor concentration was somewhat less in echo pattern B (not triple line) endometrium compared with pattern A (triple line) endometrium. Oestrogen and progesterone receptor concentrations appeared stable on gonadotrophin induction, though fewer numbers were found during clomiphene cycles than in natural cycles. With regard to the distribution of receptor concentration between clomiphene and natural cycles, most women using clomiphene had very low oestrogen receptor populations. Pregnancy rates were low, in spite of high ovulatory rates during clomiphene treatment and were mainly related to low oestrogen receptor concentrations in preovulatory endometrium.  (+info)

Oxytocin and vasopressin receptors in human and uterine myomas during menstrual cycle and early pregnancy. (5/1799)

The purpose of this study was to determine the specificity and concentration of oxytocin (OT) and arginine vasopressin (AVP) binding sites in non-pregnant (NP) human and rhesus monkey endometrium, myometrium and fibromyomas, and to determine the cellular localization of OT receptor (OTR). Besides [3H]AVP, [125I]LVA, a specific VP1 receptor subtype antagonist, was used to determine vasopressin receptor (VPR) concentrations. Samples were obtained from 42 pre-menopausal and three pregnant women (5, 13 and 35 weeks gestation), and several NP and pregnant monkeys. Specificity of binding was assessed in competition experiments with unlabelled agonists and antagonists of known pharmacological potency. Cellular localization of OTR was determined by immunohistochemistry. In NP human uterine tissues, [3H]AVP was bound with higher affinity and greater binding capacity than [3H]OT, whereas in pregnant women and in NP and pregnant rhesus monkeys, uterine OT binding capacity was greater. OT and AVP binding sites discriminated very poorly between OT and AVP; [125I]LVA binding sites were more selective than [3H]AVP. Their ligand specificity and binding kinetics indicated the presence of two distinct populations of binding sites for OT and AVP in primate uterus. Endometrium of NP women and monkeys had low OTR and VPR concentrations. Myometrial and endometrial OTR and VPR were down-regulated in midcycle and in early human pregnancy, they were up-regulated in the secretory phase and second half of pregnancy. Immunoreactive OTR in NP uterus was localized in patches of myometrial muscle cells and small numbers of endometrial epithelial cells.  (+info)

Expression of the oxytocin receptor in relation to steroid receptors in the uterus of a primate model, the marmoset monkey. (6/1799)

The dynamics of the receptors for oestrogen (ER), progesterone (PR) and oxytocin (OTR) in the marmoset uterus have been analysed throughout the entire cycle and early pregnancy. Uteri obtained during the early, mid/late and late proliferative phase, and the early, mid and late secretory phase and early pregnancy were examined by immunohistochemistry (OTR, ER, PR) and autoradiography (OTR). A massive upregulation of the ER in the cell nuclei of glandular epithelium and stromal cells during the mid proliferative phase was succeeded by a declining staining intensity and positively stained cell number in the secretory phase. PR immunoreactivity increased in the late proliferative phase and early secretory phase, mainly within the cell nuclei, and then declined in both intensity and cell number towards the mid to late secretory phase. Myometrium showed a similar staining pattern for the steroid receptors. OTR were expressed weakly in stroma throughout the entire cycle, increasing slightly in the secretory phase. Glandular epithelium showed positive staining only during the periovulatory period. Myometrial OTR expression was weak during the proliferative phase, increased towards the secretory phase, and was maximal in the late secretory phase. Myometrial tissue adjacent to endometrium was most strongly stained. A cyclic shift evidently occurred in the pattern of steroid receptors, perhaps reflecting the steroid environment or the luteinizing hormone increase associated with ovulation.  (+info)

Sonographic evidence for the involvement of the utero-ovarian counter-current system in the ovarian control of directed uterine sperm transport. (7/1799)

Sperm transport from the cervix into the tube is an important uterine function within the process of reproduction. This function is exerted by uterine peristalsis and is controlled by the dominant ovarian structure via a cascade of endocrine events. The uterine peristaltic activity involves only the stratum subvasculare of the myometrium, which exhibits a predominantly circular arrangement of muscular fibres that separate at the fundal level into the fibres of the cornua and continue into the circular muscles of the respective tubes. Since spermatozoa are transported preferentially into the tube ipsilateral to the dominant follicle, this asymmetric uterine function may be controlled by the ovary via direct effects utilizing the utero-ovarian counter-current system, in addition to the systemic circulation. To test this possibility the sonographic characteristics of the uterine vascular bed were studied during different phases of the menstrual cycle. Vaginal sonography with the measurement of Doppler flow characteristics of both uterine arteries and of the arterial anastomoses of the uterine and ovarian arteries (junctional vessels) in the cornual region of both sides of the uterus during the menstrual phase of regular-cycling women demonstrated significant lower resistance indices of the junctional vessels ipsilateral to the side of the dominant ovarian structure as compared with the corresponding arteries contralaterally. By the use of the perfusion mode technique, it could be observed that vascular perfusion of the fundal myometrium was significantly increased ipsilateral to the dominant follicle during the late follicular phase of the cycle. These results show that the endocrine control of the dominant ovarian structure over uterine function is not only exerted via the systemic circulation but also directly, most probably utilizing the utero-ovarian counter-current system.  (+info)

Phenotypic and functional studies of leukocytes in human endometrium and endometriosis. (8/1799)

The aetiology of endometriosis, a common and disabling disorder, is presently unknown, although immune dysfunction could allow ectopic endometrial fragments to survive outside the uterine cavity. These studies investigate the relationship between leukocyte populations, steroid hormone receptor expression, proliferative activity, bcl-2 expression and apoptosis in eutopic and ectopic endometrium from women with endometriosis or adenomyosis at different phases of the menstrual cycle. Significantly increased oestrogen receptor expression, bcl-2 expression and numbers of CD8+ leukocytes were found in ectopic compared with eutopic endometrium in endometriosis, and CD56+ endometrial granulated lymphocytes (eGLs) were significantly reduced in ectopic endometrium. Apoptotic cells were rarely found in control and subject endometria. In contrast with endometriosis, adenomyotic lesions showed identical steroid hormone receptor expression, proliferative activity, bcl-2 expression and leukocyte subpopulations to eutopic endometrium, indicating different aetiologies for these disorders. The unusual CD56+ CD16- eGLs present in large numbers in late secretory phase eutopic endometrium were highly purified (>98%) by immunomagnetic separation. Except for a negligible cytotoxic activity of eGLs from early proliferative samples, cytotoxic activity of eGLs from non-pregnant endometrium during the menstrual cycle was comparable with those in peripheral blood, predominantly CD56+ CD16+ natural killer cells. eGLs from non-pregnant endometrium and early pregnancy showed a variable proliferative response to 5 and 100 U/ml interleukin-2 over 48-h and 120-h time courses. eGLs are evidently functionally important in the eutopic endometrium. Their absence in endometriotic lesions together with increased CD+8 T-cell numbers and increased oestrogen receptor and bcl-2 expression may have significant effects on the development and progression of endometriosis.  (+info)

AU - Szeliga, Kendall T.. AU - Purdy, Robert H.. AU - Grant, Kathleen (Kathy). PY - 1999/10. Y1 - 1999/10. N2 - Previous studies showed that sensitivity to the ethanol-like discriminative stimulus effects of allopregnanolone and ethanol are enhanced during the luteal phase of the menstrual cycle when progesterone levels peak in monkeys trained to discriminate 1.0 g/kg ethanol. The present study further explored the influence of the menstrual cycle phase on the discriminative stimulus effects of ethanol, allopregnanolone, and midazolam. Female adult cynomolgus monkeys (Macaca fascicularis) were trained to discriminate 1.0 g/kg ethanol (n = 3) or 2.0 g/kg ethanol (n = 4) (20% w/v; IG) from water (IG). A cumulative dosing procedure was used to test discriminative stimulus effects of ethanol (0.5-2.5 ...
A normal menstrual cycle is normally from 28- 35 days, without any symptom that causes discomfort (excluding dull pain) and menstrual discharge is red and last from 3- 5 days without spotting. Not all women with abnormal menstrual cycle are infertile, but if you are diagnosed with the unexplained cause of infertility, then your abnormal menstrual cycle may be the cause. Traditional Chinese medicine, before treating any cause of infertility would like to restore your normal menstrual cycle so you can conceive quickly. Girls in southest Asia has learnt early from the grandmother wisdoms, that maintaining the normal menstrual cycle is the main objective for easy conception and any menstrual disorder should be looked after immediately ...
2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) is a widespread industrial environmental contaminant. Animal studies suggest that TCDD exposure alters the estrus cycle. Twenty years after a 1976 industrial explosion in Seveso, Italy, the authors interviewed female residents to determine whether there was an association between TCDD exposure and current menstrual cycle characteristics. The authors analyzed serum samples collected soon after the explosion to quantify individual TCDD levels. Among women who were premenarcheal at the time of the explosion, a 10-fold increase in serum TCDD level was associated with a lengthening of the menstrual cycle by 0.93 days (95% confidence interval (CI): -0.01, 1.86) and a reduction in the odds of scanty menstrual flow (adjusted odds ratio = 0.33, 95% CI: 0.10, 1.06). However, among women who were postmenarcheal at the time of the explosion, TCDD was not associated with menstrual cycle length (adjusted β = -0.03 days, 95% CI: -0.61, 0.54) or scantiness of flow ...
Each woman will be seen in 6 visits and will be contacted by two scheduled follow-up telephone calls/visits. Volunteers will be consented at Visit 1 and undergo procedures to assess whether they are eligible to continue in the study.

N2 - Understanding variations in lipoprotein cholesterol levels throughout the menstrual cycle is important because there may be clinical implications regarding the appropriate timing of measurement and implications on the design and interpretation of studies in women of reproductive age. Our objective was to review the evidence comparing lipoprotein cholesterol levels throughout the menstrual cycle among premenopausal women. Overall, lipoprotein cholesterol levels were observed to vary in response to changing estrogen levels. Taken together, the evidence suggests that total cholesterol and LDL-C tend to be highest during the follicular phase and to decline during the luteal phase, with HDL-C highest around ovulation. Based on these findings, the menstrual cycle ...

The shedding of HIV in vaginal and cervical secretions fluctuates with a womans menstrual cycle, according to a study published in the June 15th edition of Clinical Infectious Diseases, which is now available online. The findings also suggest that the risk of HIV transmission may be higher at certain points in the menstrual cycle. Investigators from Kenya and the US wished to establish the relationship between hormonal fluctuations during the menstrual cycle and HIV RNA shedding in cervical and vaginal secretions. During the course of a complete menstrual cycle, 17 women with HIV had daily swabs to determine the level of HIV shedding in the cervix and vagina. Blood tests were performed three times a week to establish serum HIV viral load and serum levels of the hormones estradiol and progesterone. In particular, the investigators wished to establish if there was any relationship between the luteinizing hormone surge and cervical and vaginal secretion of HIV. The 17 women attended 98% of their ...

The aim of this study was evaluation of expression patterns of VEGF and Flk-1 in human endometrium during the menstrual cycle. Methods: Sixty paraffin-embedded blocks of endometrial tissues from the patients with normal menstrual cycles were obtained. Tissue samples were assembled into tissue microarray slides and classified by histological dating into five phases: the proliferative (n=14), peri-ovulatory (n=9), early-secretory (n=12), mid-secretory (n=11) and late-secretory (n=14) phases. Immunohistochemical staining was performed using VEGF or Flk-1 monoclonal antibodies. The ...
Not every royal krovootdelenie that occurs regularly with a certain period of time can be regarded as menstruation.A normal menstrual cycle occurs only when the ovaries under the influence of gonadotropins occurs oocyte maturation, ovulation, corpus luteum formation, and in the uterus (under the influence of sex hormones) to implement the transformation of its mucosa.If this does not occur, we can talk about the menstrual cycle, which may be due to various reasons and may be very diverse in nature.. Since the normal menstrual cycle is the result of a complex neuroendocrine ovarian correlation with higher vegetative centers, insofar as the violation in the area of ​​the hypothalamus - pituitary gland and ovaries (violation of each of these units) may be the cause of menstrual disorders.. The basis of most classifications of violations of the menstrual cycle is split into two opposing clinical groups: hypomenstrual syndrome associated with a decrease or absence of menstruation, and uterine ...
Ladies - can you pin point specific phases in your menstrual cycle by your symptoms? I know, its not exactly dinner talk, but Im being serious.. Do you have any varying level of these symptoms?. - Fatigue. - Cramping. - Bloating. - Breast tenderness. - Fluctuations in body temperature. - Energy. - Hunger. - Moodiness. Have you noticed a difference in your workouts around your period?. If you need a refresher about your menstrual cycle - and trust me I did after I stopped taking hormonal birth control here it is below:. *Menstrual phase - days 1 to 5. *Follicular phase - days 1 to 13. Ovulation phase - day 14. Luteal phase - days 15 to 28. *In some texts, the menstrual phase and follicular phase are grouped together. These are average lengths of time, every woman is different, which means every cycle may be shorter or longer (Reed & Carr, 2015).. The first day of the menstrual phase is when your period starts. A healthy period can last between three to five days. During this phase, the ...
What is happening internally? The corpus luteum continues to release high amounts of progesterone, to maintain the uterine lining. If conception occurred, the blastocyst (the fertilized egg) is floating out of the fallopian tube and into the uterus.
What is happening internally? The corpus luteum continues to release high amounts of progesterone, to maintain the uterine lining. The ovum (egg), if fertilized, changes from the ball of cells known as a morula, into a blastocyst - a cluster of cells with a fluid-filled cavity.
Since 1980, Dr. Jerilynn C. Prior and colleagues have been studying womens menstrual cycles and ovulation. A focus has been on longitudinal observational studies analyzing within-woman changes in response to, for example, exercise training or chemotherapy for breast cancer. Documented changes occur within the menstrual cycle and ovulation, in physical and emotional experiences and in bone mineral density and bone metabolism. Another primary focus for research is using randomized controlled trials to assess the effects of progesterone therapy on metabolism, endothelial function, hot flushes/night sweats, experiences and bone changes.The Centre for Menstrual Cycle and Ovulation Research philosophy is that each participant becomes part of the research team, is provided her own and preliminary results and provides feedback on the project. Dr. Prior personally undergoes all research interventions before they are approved as part of any research.The Centre for Menstrual Cycle Research and Ovulation
Menstrual cycle phases are an important part of your life. Find out whats going on at each stage of your cycle so you know what to expect.
Understanding the menstrual cycle phases and the regulating hormones, helps a woman know her body better. This article provides all the information about it
The phases of your menstrual cycle are triggered by hormonal changes.. Menstrual period. On Day 1 of your cycle, the thickened lining (endometrium) of the uterus begins to shed. You know this as menstrual bleeding from the vagina. A normal menstrual period can last 4 to 6 days.. Most of your menstrual blood loss happens during the first 3 days. This is also when you might have cramping pain in your pelvis, legs, and back. Cramps can range from mild to severe. The cramping is your uterus contracting, helping the endometrium shed. In general, any premenstrual symptoms that youve felt before your period will go away during these first days of your cycle.. Follicular phase. During the follicular phase, an egg follicle on an ovary gets ready to release an egg. Usually, one egg is released each cycle. This process can be short or long and plays the biggest role in how long your cycle is. At the same time, the uterus starts growing a new endometrium to prepare for pregnancy.. The last 5 days of the ...
The follicular phase ranges from 7 to 21 days or 32 days for teenagers. Its the variable part of the menstrual cycle. In contrast, the luteal phase is almost exactly fourteen days (ten to sixteen days) and does not vary. If you add up the variable (follicular) phase to the fixed (luteal) phase, the duration of a healthy menstrual cycle is anywhere between 21 to 35 days or 45 days for teenagers.. Tip: To determine the length of your menstrual cycle, start counting from your first day of proper flow. Thats day 1. The days of light spotting that lead up to the proper flow are the final days of the luteal phase of the previous cycle.. If theres no ovulation, then theres no luteal phase or progesterone and that can result in a period thats too heavy or goes on for too long. Why? Because progesterone is the period-lightening hormone ...

Introduction: The autonomic control of the heart is assumed to be affected by endogenous hormonal fluctuations in normal ovulatory females. Analyzing heart rate variability (HRV) had become a tool for the noninvasive measurement of cardiac autonomic control. The purpose of the present study was to investigate the course of the HRV parameters in moderately active as well as in long time endurance trained women during the menstrual cycle. Methods: Normal ovulatory females, untrained and trained were enrolled. Female athletes were involved in individually different training patterns (,5h/week) during the study. HRV recordings were obtained during five different menstrual cycle phases: menstruation (M), middle of follicular (MidF), ovulation (O), middle of luteal (MidL) and pre menstruation phase (PreM). Phases were verified by basal body temperature and analysis of luteinizing hormone (LH), follicular stimulation hormone (FSH), β-17 estrogen (E2) and progesterone (P). HRV measurements took place ...

A regular menstrual cycle runs for 28 days. That means thats the usual interval between the first day of bleeding until the next. However, both teens and older women will encounter irregularities with their menstrual cycles for different reasons. Teens may experience longer cycles, only for it to get shorter the following month. This is because their bodies are still adjusting to the changes. But their cycle would get normal in time. For older women, the changes they experience can be attributed to the fact that theyre nearing menopause. As such, their menstrual cycle tends to get longer and longer until it stops ...

Research has been conducted on how different aspects of a human females life vary across her menstrual cycle. At different points in a womans menstrual cycle her attractiveness to men differs, with peak attractiveness occurring during her fertile window. A woman is seen as most attractive when leading up to her ovulatory cycle, with high oestrogen levels, while seen as less attractive post ovulation, with high progesterone levels. Women experience subtle changes to their facial appearance, vocal quality and gait when they are within their fertile window. One study found that when in ovulation lap dancers receive the greatest amount of tips. Changes across the cycle are more subtle in humans than in other mammalian species; who may experience sexual swellings when fertile while being unattractive and unreceptive towards males when non-fertile. Sexual feelings and behaviours change around the menstrual cycle. Before and during ovulation, high levels of oestrogen and androgens result in women ...
Normal Menstrual Cycle or menstruation or menses is a term used to describe the monthly shedding of the uterus lining in women. As a result, the menstrual blood, comprising blood and tissue from the uterus, flows out of the body through the cervix and vagina.

OpenStax Biology 2e. The ovarian cycle governs the preparation of endocrine tissues and release of eggs, while the menstrual cycle governs the preparation and maintenance of the uterine lining. These cycles occur concurrently and are coordinated over a 22-32 day cycle, with an average length of 28 days.. The first half of the ovarian cycle is the follicular phase. Slowly rising levels of FSH and LH cause the growth of follicles on the surface of the ovary. This process prepares the egg for ovulation. As the follicles grow, they begin releasing estrogens and a low level of progesterone. Progesterone maintains the endometrium to help ensure pregnancy. The trip through the fallopian tube takes about seven days. At this stage of development, called the morula, there are 30-60 cells. If pregnancy implantation does not occur, the lining is sloughed off. After about five days, estrogen levels rise and the menstrual cycle enters the proliferative phase. The endometrium begins to regrow, replacing the ...
The normal human mammary gland undergoes a well defined sequence of histological changes in both epithelial and stromal compartments during the menstrual cycle. Studies in vitro have suggested that the extracellular matrix surrounding the individual cells plays a central role in modulating a wide variety of cellular events, including proliferation, differentiation and gene expression. We therefore investigated the distribution of a number of extracellular matrix molecules in the normal breast during the menstrual cycle. By use of indirect immunofluorescence, with specific antibodies, we demonstrated that laminin, heparan sulphate proteoglycan, type IV collagen, type V collagen, chondroitin sulphate and fibronectin undergo changes in distribution during the menstrual cycle, whereas collagen types I, III, VI and VII remain unchanged. These changes were most marked in the basement membrane, sub-basement membrane zone and delimiting layer of fibroblasts surrounding the ductules where basement ...

The issues contributing to these gender differences are unknown; a number of case reports have indicated the possibility of mood changes secondary to hormonal influences during the menstrual cycle. We sought to examine the relationship between bipolar disorder and menstrual cycle-related mood changes. To our knowledge, this is one of the largest samples in the literature addressing this issue. Methods: ...
Gingival inflammation was lower during menstruation than during ovulation and premenstruation, said Machtei. This may be attributed to the hormone known as serum estradiol, which is a natural form of estrogen that peaks and drops during ovulation and premenstruation. Further studies will be required to explore the mechanism by which this phenomenon occurs, and to examine whether these transitional changes have any lasting negative effects on the periodontium, said Michael P. Rethman, D.D.S., M.S., and president of the American Academy of Periodontology. In the meantime, patients should remember the importance of telling their dental professionals about what is going on in their bodies including any prescription or over-the-counter medications they are taking. This way dental professionals can explain any effects it has on periodontal health ...

Context: Female reproductive aging based on changes in menstrual cycle length and frequency progresses through a number of stages as defined by the Stages of Reproductive Aging Workshop (STRAW) staging criteria. Objective: This paper provides a comprehensive description of the endocrine features associated with the STRAW stages. Design: Healthy women aged 21-35 and 45-55 yr
This article aims to throw light on the controversial topic of whether women have a heat period within their menstrual cycle. The majority of publications in this field report, in addition to a periovulatory peak, no changes at all or even rises in male- and female-initiated sexual activity, womans sexual desire, autosexual activity and sexual arousability, and interpersonal sexual activities during the mid-follicular and late luteal phases. The lack of a distinct pattern of womens sexual behaviour across the menstrual cycle may be explained by the interplay between cyclical endocrine fluctuations and many psychological, social, cultural and environmental factors, as well as the methodological shortcomings associated with menstrual cycle research. However, studies focused on cycling changes in womens olfactory and visual perception show that, in comparison with women at other phases of the menstrual cycle, women at mid-cycle exhibit increased sexual motivation that biases recognition ...

Background: Fibroadenoma is the most common breast tumor in young women, and its growth and metabolism may be under hormonal control. in the present paper we described the proteoglycan (PG) composition and synthesis rate of normal breast and fibroadenoma during the menstrual cycle.Methods: Samples of fibroadenoma and adjacent normal breast tissue were obtained at surgery. PGs were characterized by agarose gel electrophoresis and enzymatic degradation with glycosaminoglycan (GAG) lyases, and immunolocalized by confocal microscopy. To assess the synthesis rate, PGs were metabolic labeled by S-35-sulfate.Results: the concentration of PGs in normal breast was higher during the secretory phase. Fibroadenoma contained and synthesized more PGs than their paired controls, but the PG concentrations varied less with the menstrual cycle and, in contrast to normal tissue, peaked in the proliferative phase. the main mammary GAGs are heparan sulfate (HS, 71%-74%) and dermatan sulfate (DS, 26%-29%). the ...
The luteal phase is the final phase of the menstrual cycle and lasts from your day of ovulation to the last day before your next period. Glands in the endometrium (lining of the uterus) secrete proteins in preparation for the implantation of the fertilized egg (embryo). If you get pregnant, the embryo will implant itself in the endometrium during this phase. If implantation does not occur, the endometrium starts to break down and is eventually sloughed off: this is menstruation. The luteal phase is named after the corpus luteum (Latin for yellow body), a structure that grows in the ovary. The luteal phase is dominated by progesterone, which is also the hormone responsible for the rise in body basal temperature (BBT).. Precise identification of your ovulation day allows you to time your baby-making intercourse for the most fertile days of your menstrual cycle to increase your chances of getting pregnant.. Confirmation of ovulation in the home environment is only possible through measuring body ...

BACKGROUND:. Premenstrual dysphoric disorder (PMDD) has generally not been associated with impulsive behavior. However, some studies suggest that women with PMDD have higher impulsivity scores than healthy controls and that brain activity during response inhibition may vary across the menstrual cycle. Therefore, our aim was to unravel potentially important cognitive aspects of PMDD by investigating brain activity during response inhibition in women with PMDD and healthy controls in relation to menstrual cycle phase.. METHODS:. Fourteen PMDD patients and 13 healthy controls performed a Go/NoGo task to measure brain activity during response inhibition by use of event-related functional magnetic resonance imaging.. RESULTS:. Women with PMDD displayed decreased activity during both menstrual cycle phases compared to healthy controls in several task-related parietal areas. A significant group by phase interactions was found in the left insula, driven by enhanced activity among healthy controls in the ...

TY - JOUR. T1 - The function and regulation of the primate corpus luteum during the fertile menstrual cycle.. AU - Stouffer, Richard. AU - Ottobre, J. S.. AU - Molskness, T. A.. AU - Zelinski, Mary. PY - 1989. Y1 - 1989. N2 - Figure 2 summarizes the changes in endocrine function and the factors which regulate the primate corpus luteum during the fertile menstrual cycle. The classical luteotropic role of LH during the menstrual cycle is superceded by CG at or before the time of implantation. The role of local factors in modulating luteal function is an area of continued research, as some factors are deemed less important (i.e., estrogen, at least prior to luteal rescue) and other possibilities (progesterone, prostaglandins, and relaxin) arise. The role of local factors has not yet been studied in the corpus luteum following its rescue in early pregnancy. Finally, it is apparent that a different type of shift precedes the recognized luteal-placental shift in early pregnancy, when the corpus ...
TY - JOUR. T1 - Differences in lectin binding patterns of normal human endometrium between proliferative and secretory phases. AU - Aoki, D.. AU - Kawakami, H.. AU - Nozawa, S.. AU - Udagawa, Y.. AU - Iizuka, R.. AU - Hirano, H.. PY - 1989/5/1. Y1 - 1989/5/1. N2 - Lectin binding patterns in normal human endometrium were examined by light and electron microscopy using seven different lectins (ConA, WGA, RCA, PNA, UEA-1, DBA, and SBA). For light microscopic observations, criteria based on the incidence and intensity of cells positive for the lectin staining were adopted to evaluate the different staining patterns of the proliferative and secretory endometria obtained by the avidin-biotin-peroxidase complex (ABC) technique. At the light microscopic level, ConA, WGA, and RCA stained endometrial glandular cells in both phases. The number of PNA-positive cells with the binding sites entirely limited to the apical surface tended to be reduced slightly in the secretory phase. UEA-1 weakly stained the ...
A low hemoglobin level in blood, also known as anemia, is a condition which develops when your blood does not have enough hemoglobin and healthy red blood cells. Know the causes, symptoms, treatment of low hemoglobin levels in women and its effects on menstrual cycle.
Premenstrual period means that in the menstrual cycle (if 28 days is a menstrual cycle), the date of the cramp is more than one week earlier (that is, the cycle is less than 21 days), and more than two consecutive menstrual cycles are less than 21 days. This is a gynecological disease characterized by changes in the menstrual cycle. Contrast with late menstruation and irregular menstruation. Therefore, the late menstrual cycle means that the error is more than 7 days after the menstrual cycle (that is, if the cycle is 28 days, the menstrual cycle exceeds 35 days), and it occurs more than two consecutive menstrual cycles. Even 3-5 months of menstruation belong to the latter stage of menstruation, but if the menarche is less than a year and the perimenopausal cycle is delayed without any physical discomfort, it is not considered disease. Irregular menstruation means that the menstrual cycle is advanced or delayed for more than one week and more than three consecutive cycles. Early menstruation and ...
For urinalysis, midstream collection is recommended (1)(2)(3). Health-associated reference limits for leukocyte and erythrocyte counts in female urine are important for detecting hematuria, pyuria, and urinary tract infection (3). To understand the effects of urinary collection and the menstrual cycle on urinalysis, we examined first-stream and midstream urine samples from healthy female students with use of an automated dipstick reader and the fully automated urine cell analyzer, UF-100.. Specimens were obtained from 64 healthy female students (age range, 18-20 years) at the College of Medical Technology. All were asymptomatic and had no extant urologic disease. They were instructed to collect only first and midstream urine samples in sterile containers at the same time and not to wipe or spread the labia. The volume of the first urine was measured, and the specimen was analyzed within 2 h. The students provided written, informed consent to participate in the study as well as information about ...

Background: Long and irregular menstrual cycles, a hallmark of polycystic ovary syndrome (PCOS), have been associated with higher androgen and lower sex hormone binding globulin levels (SHBG) and this altered hormonal environment may increase the risk of specific histologic subtypes of ovarian cancer.. Methods: We investigated the association between menstrual cycle characteristics and PCOS among 2071 women with epithelial ovarian cancer and 2100 controls in the New England Case-Control Study (1992-2008). Women self-reported menstrual cycle irregularity, menstrual cycle length, and previous diagnosis of PCOS. We used unconditional logistic regression models to calculate odds ratios (OR) and 95% confidence intervals (95% CIs) for ovarian cancer risk overall, and polytomous logistic regression to evaluate whether the associations differed across histologic subtypes.. Results: Overall, we observed no difference in ovarian cancer risk between women who reported periods that were never regular and ...
Regulatory T cells (Tregs) are thought to affect the severity of various infectious and autoimmune diseases. The incidence of autoimmune disease is higher in fertile women than in men. Thus, we investigated whether Treg numbers were modulated during the menstrual cycle by sex hormones. In fertile nonpregnant women, we detected an expansion of CD4(+)CD25(+)FOXP3(+) Tregs in the late follicular phase of the menstrual cycle. This increase was tightly correlated with serum levels of estradiol and was followed by a dramatic decrease in Treg numbers at the luteal phase. Women who have had recurrent spontaneous abortions (RSA) showed similarly low numbers of Tregs at both the follicular and luteal phases, comparable to numbers we observed in postmenopausal women. In addition to decreased numbers, Tregs from women with RSA were also functionally deficient, as higher numbers were required to exert a similar magnitude of suppression to CD4(+)CD25(+)FOXP3(+) cells from fertile women. Consequently, reproductive
Mammography may detect cancer more effectively in younger women if the test is done during the first two weeks of the menstrual cycle, according to researchers at the Fred Hutchinson Cancer Research Center in Seattle.. In a study to be published tomorrow (June 17) in the Journal of the National Cancer Institute, epidemiologist Emily White, Ph.D., and colleagues from the Hutchinson Centers Division of Public Health Sciences, Group Health Cooperative of Puget Sound and the University of Washington are the first to report an association between menstrual phase and breast density as detected on a mammogram.. The researchers found that as the menstrual cycle progresses, breast tissue becomes less fatty (transparent) and more fibrous and dense (opaque), most likely due to fluctuations in reproductive hormones. This density, which appears as increased cloudiness on a mammogram, can make it more difficult to detect tiny, early stage malignancies among pre-menopausal women.. As a result, the researchers ...

The cyclic production of estrogen and progesterone during the ovarian cycle induces a corresponding cycle of endometrial proliferation and development. (Fig. 1, bottom panel). This endometrial cycle includes a proliferative phase lasting about 11 days, a secretory phase lasting about 12 days, and a desquamative or menstrual phase of about five days during which menstruation ensues.. During the follicular phase of the ovarian cycle, the endometrium proliferates and increases in thickness under the influence of estradiol. This marks the proliferative phase of the endometrial cycle. During the luteal phase of the ovarian cycle, progesterone stimulates further endometrial cell proliferation, differentiation, and secretory development to support implantation and to nourish the developing conceptus. This is the secretory phase of the endometrial cycle. Progesterone also promotes secretory changes in the lining of the fallopian tubes that will support the fertilized egg as it travels down the fallopian ...

Cervical and vaginal secretions from 17 women infected with human immunodeficiency virus type 1 (HIV-1) were evaluated daily through the course of one menstrual cycle for HIV-1 DNA (21-31 visits per woman). HIV-1-infected cells were detected in 207 (46%) of 450 endocervical swabs and 74 (16%) of 449 vaginal swabs. There was considerable variability in the percentage of positive swabs from each woman, ranging from 4% to 100% of endocervical swabs and from 0 to 71% of vaginal swabs. In multivariate analyses, plasma HIV-1 RNA was significantly associated with shedding of HIV-1-infected cells; each 1-unit increase in the log of plasma virus load was associated with a 5.6-fold increase in the odds of cervical shedding (95% confidence interval [CI], 2.1-14.8) and a 3.9-fold increase in the odds of vaginal shedding (95% CI, 2.1-7.2). There was no discernible pattern of genital tract shedding with phase of the menstrual cycle and no significant association with serum estradiol or progesterone levels ...

For this theory to gain credibility it is necessary to find a source. If you have women migrating to each others menstrual cycles, then you would need an alpha woman that the others are migrating towards. Research done at the Sonoma State Hospital Brain Behavior Research Center in California identified women believed to be dominate and the pacesetters and used to pheromones to see if they caused an effect on the menstrual cycle of other women. They experiment involved collecting pheromones from the arm pit of these women onto cotton pads. The dominate women wore these pads under their arm pits for a day. From there, they placed the pheromone covered cotton pads on the upper lips of other six other women, three times a week. After five months, five out of the six women where cycled with the dominate womans cycle ...
The effects of chronic alcohol intake on menstrual cycle status and hormonal function were studied in 26 healthy, adult women under controlled research ward conditions. Women were classified as heavy, social or occasional alcohol users on the basis of the actual number of drinks consumed during 3 consecutive weeks of alcohol availability. Heavy, social and occasional users drank an average of 7.81 ( +/- 0.69), 3.84 ( +/- 0.19) and 1.22 ( +/- 0.21) drinks/day, respectively. This drinking pattern was highly consistent with subjects self-reports of alcohol use before the study. No evidence of menstrual cycle dysfunction or abnormality in reproductive hormone levels was found in the occasional drinkers or in two of the social drinkers who consumed less than an average of three drinks/day. In contrast, 50% of the social drinkers who consumed more than three drinks/day and 60% of the heavy drinkers had significant derangements of menstrual cycle and reproductive hormone function. The major ...

A double-blind, prospective study during the fall of 1979 investigated the association between the menstrual cycles of 305 Brooklyn College undergraduates and their associates and the lunar cycles. All subjects were 19-35 years old and using neither OCs (oral contraceptives) nor the IUD. Approximately 1/3 of the subjects had lunar period cycles, i.e., a mean cycle length of 29.5 +/- l day. Almost 2/3 of the subjects started their October cycle in the light 1/2 of the lunar cycle, significantly more than would be expected by random distribution. The author concludes that there is a lunar influence on ovulation.. ...
Epilepsy is a chronic neurological condition characterized by recurrent seizures. Catamenial epilepsy is a subset of epilepsy, which includes women whose seizures are exacerbated by their menstrual cycle. Women with catamenial epilepsy are unusually sensitive to endogenous hormonal changes. This seizure exacerbation has a statistically significant positive correlation to serum estradiol/estrogen levels and ratios. Since at least the Greek times, there has been documented study of women with epilepsy and its correlation to the menstrual cycle. These patterns can easily be seen by charting out menses against seizure occurrence and type. Our understanding of the major gonadal hormones, estrogen, progesterone, and testosterone, has significantly increased in the last century. These hormones are synthesized in various locations in the body, including the ovaries, adrenal gland, liver, subcutaneous fat, and brain. There is considerable research showing that these steroidal hormones take part in an ...
Progesterone is one of two important hormones for women (estrogen is the one we usually hear about). Menstrual cycle hormone levels can be disturbed, even during regular cycles. The most common disturbance is of ovulation causing progesterone levels to become too low or absent. Your doctor may prescribe progesterone to control heavy periods, severe menstrual cramps
Levels of estradiol in premenopausal women are highly variable throughout the menstrual cycle and reference ranges widely vary from source to source.[60] Estradiol levels are minimal and according to most laboratories range from 20 to 80 pg/mL during the early to mid follicular phase (or the first week of the menstrual cycle, also known as menses).[61][62] Levels of estradiol gradually increase during this time and through the mid to late follicular phase (or the second week of the menstrual cycle) until the pre-ovulatory phase.[60][61] At the time of pre-ovulation (a period of about 24 to 48 hours), estradiol levels briefly surge and reach their highest concentrations of any other time during the menstrual cycle.[60] Circulating levels are typically between 130 and 200 pg/mL at this time, but in some women may be as high as 300 to 400 pg/mL, and the upper limit of the reference range of some laboratories are even greater (for instance, 750 pg/mL).[60][61][63][64][65] Following ovulation (or ...
Human beings and the great apes (chimpanzees, gorillas, and orangutans) experience a true menstrual cycle. Old World Monkeys (baboons, macaques, etc.) are sometimes included as having a menstrual cycle depending on how terms are defined. However, most placental mammals-such as dogs, cats, elephants, and New World Monkeys (howler, capuchin, and spider monkeys, etc.)-experience estrus instead. One difference is that animals that have estrous cycles reabsorb the endometrium if conception does not occur during that cycle. Animals that have menstrual cycles shed the endometrium through menstruation instead. Another difference is sexual activity. In species with estrous cycles, females are generally only sexually active during the estrous phase of their cycle (near the time of ovulation). This is also referred to as being in heat. In contrast, females of species with menstrual cycles can be sexually active at any time in their cycle, even when they are not about to ovulate. Humans, unlike some other ...
Menopause is a time of change. Though many women do suffer unpleasant symptoms during menopause, it can be a time of positive change. There is plenty of evidence which shows that preparing for mid-life with a good diet, lifestyle and exercise programme will greatly improve the way women experience menopause and beyond.. Menopause literally means stopping menstruation. Hormonal changes start a number of years before this and these fluctuations can continue for quite a few years into the menopause. The term peri-menopausal is often used to define the period of change before menopause and this is a good time to seek support. Once youve gone through 12 consecutive months without a menstrual period, youve officially reached menopause.. The level of your oestrogen - the main female hormone - rises and falls unevenly during peri-menopause. Your menstrual cycles may lengthen or shorten, and you may begin having menstrual cycles in which your ovaries dont release an egg (ovulate). You may also ...
In the early 1990s, researchers at Georgetown University, Pennsylvania State University, and the University of Utah proposed a five-year longitudinal study of female reproductive aging that would include the collection of hormonal, menstrual cycle, and health data from a group of women in order to advance the current understanding of the transition through menopause. The women selected for the BIMORA project were a subset of women belonging to the Tremin Research Program on Womens Health (TREMIN), a longitudinal, prospective study of menstrual cycles and female reproductive health that was begun in the 1930s by Dr. Alan Treloar at the University of Minnesota. As part of the TREMIN study, women recorded their menstrual cycles on calendar cards and were also asked to fill out annual and later biannual health surveys. The first cohort of women was recruited in the 1930s when many of them were attending the University of Minnesota. Some of their daughters, along with additional women, were ...

Does this mean there is an eating disorder?. Not always, no. There can be various causes, only one of which is an eating disorder like Anorexia or Bulimia. Disordered eating is a better term as this includes a wider spectrum of conditions ultimately resulting in Low Energy Availability.. Are only elite athletes at risk?. No, all athletes at various levels of competition can be at risk. It is very easy for even recreational athletes to develop RED-S with all the societal pressures on leanness as well as all the fad-diets doing their rounds.. Why are menstrual cycles so important?.
