The inner cell mass gives rise to the embryonic disc and eventual embryo proper.Body Weight: The mass or quantity of heaviness of an individual. It is expressed by units of pounds or kilograms.Reproduction: The total process by which organisms produce offspring. (Stedman, 25th ed)Fertility Agents, Female: Compounds which increase the capacity to conceive in females.Uterine Neoplasms: Tumors or cancer of the UTERUS.Uterine Contraction: Contraction of the UTERINE MUSCLE.Administration, Intravaginal: The insertion of drugs into the vagina to treat local infections, neoplasms, or to induce labor. The dosage forms may include medicated pessaries, irrigation fluids, and suppositories.Menstruation: 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.Apgar Score: A method, developed by Dr. Virginia Apgar, to evaluate a newborn's adjustment to extrauterine life. Five items - heart rate, respiratory effort, muscle tone, reflex irritability, and color - are evaluated 60 seconds after birth and again five minutes later on a scale from 0-2, 0 being the lowest, 2 being normal. The five numbers are added for the Apgar score. A score of 0-3 represents severe distress, 4-7 indicates moderate distress, and a score of 7-10 predicts an absence of difficulty in adjusting to extrauterine life.Prevalence: The total number of cases of a given disease in a specified population at a designated time. It is differentiated from INCIDENCE, which refers to the number of new cases in the population at a given time.Pregnancy-Associated Plasma Protein-A: A product of the PLACENTA, and DECIDUA, secreted into the maternal circulation during PREGNANCY. It has been identified as an IGF binding protein (IGFBP)-4 protease that proteolyzes IGFBP-4 and thus increases IGF bioavailability. It is found also in human FIBROBLASTS, ovarian FOLLICULAR FLUID, and GRANULOSA CELLS. The enzyme is a heterotetramer of about 500-kDa.Risk: The probability that an event will occur. It encompasses a variety of measures of the probability of a generally unfavorable outcome.Chorionic Villi Sampling: A method for diagnosis of fetal diseases by sampling the cells of the placental chorionic villi for DNA analysis, presence of bacteria, concentration of metabolites, etc. The advantage over amniocentesis is that the procedure can be carried out in the first trimester.Fathers: Male parents, human or animal.Longitudinal Studies: Studies in which variables relating to an individual or group of individuals are assessed over a period of time.Labor, Induced: Artificially induced UTERINE CONTRACTION. Generally, LABOR, OBSTETRIC is induced with the intent to cause delivery of the fetus and termination of pregnancy.Reference Values: The range or frequency distribution of a measurement in a population (of organisms, organs or things) that has not been selected for the presence of disease or abnormality.Clomiphene: A triphenyl ethylene stilbene derivative which is an estrogen agonist or antagonist depending on the target tissue. Note that ENCLOMIPHENE and ZUCLOMIPHENE are the (E) and (Z) isomers of Clomiphene respectively.Labor Onset: The beginning of true OBSTETRIC LABOR which is characterized by the cyclic uterine contractions of increasing frequency, duration, and strength causing CERVICAL DILATATION to begin (LABOR STAGE, FIRST ).Reproductive Behavior: Human behavior or decision related to REPRODUCTION.Infant, Newborn, Diseases: Diseases of newborn infants present at birth (congenital) or developing within the first month of birth. It does not include hereditary diseases not manifesting at birth or within the first 30 days of life nor does it include inborn errors of metabolism. Both HEREDITARY DISEASES and METABOLISM, INBORN ERRORS are available as general concepts.Fetal Membranes, Premature Rupture: Spontaneous tearing of the membranes surrounding the FETUS any time before the onset of OBSTETRIC LABOR. Preterm PROM is membrane rupture before 37 weeks of GESTATION.Folic Acid: A member of the vitamin B family that stimulates the hematopoietic system. It is present in the liver and kidney and is found in mushrooms, spinach, yeast, green leaves, and grasses (POACEAE). Folic acid is used in the treatment and prevention of folate deficiencies and megaloblastic anemia.Prolactin: A lactogenic hormone secreted by the adenohypophysis (PITUITARY GLAND, ANTERIOR). It is a polypeptide of approximately 23 kD. Besides its major action on lactation, in some species prolactin exerts effects on reproduction, maternal behavior, fat metabolism, immunomodulation and osmoregulation. Prolactin receptors are present in the mammary gland, hypothalamus, liver, ovary, testis, and prostate.Polyhydramnios: A condition of abnormally high AMNIOTIC FLUID volume, such as greater than 2,000 ml in the LAST TRIMESTER and usually diagnosed by ultrasonographic criteria (AMNIOTIC FLUID INDEX). It is associated with maternal DIABETES MELLITUS; MULTIPLE PREGNANCY; CHROMOSOMAL DISORDERS; and congenital abnormalities.Heart Rate, Fetal: The heart rate of the FETUS. The normal range at term is between 120 and 160 beats per minute.Intrauterine Devices: Contraceptive devices placed high in the uterine fundus.Embryo, Mammalian: The entity of a developing mammal (MAMMALS), generally from the cleavage of a ZYGOTE to the end of embryonic differentiation of basic structures. For the human embryo, this represents the first two months of intrauterine development preceding the stages of the FETUS.

Prenatal nutrition: Nutrition and weight management before and during :pregnancy has a profound effect on the development of infants. This is a rather critical time for healthy fetal development as infants rely heavily on maternal stores and nutrient for optimal growth and health outcome later in life.Ovarian pregnancyPregnancy rate: Pregnancy rate is the success rate for getting pregnant. It is the percentage of all attempts that leads to pregnancy, with attempts generally referring to menstrual cycles where insemination or any artificial equivalent is used, which may be simple artificial insemination (AI) or AI with additional in vitro fertilization.Pregnancy test: A pregnancy test attempts to determine whether a woman is pregnant. Markers that indicate pregnancy are found in urine and blood, and pregnancy tests require sampling one of these substances.Interstitial pregnancyTeenage Mother (film): Teenage Mother (a.k.Unintended pregnancy: Unintended pregnancies are pregnancies that are mistimed, unplanned or unwanted at the time of conception. Unintended pregnancy mainly results from engaging in vaginal sexual activity without the use of contraception, or due to incorrect use of a contraceptive method, but may also arise from the failure of the contraception method when used correctly to prevent pregnancy.Gestational age: Gestational age (or menstrual age) is a measure of the age of a pregnancy where the origin is the woman's last normal menstrual period (LMP), or the corresponding age as estimated by other methods. Such methods include adding 14 days to a known duration since fertilization (as is possible in in vitro fertilization), or by obstetric ultrasonography.Gestational thrombocytopeniaPlacenta: The placenta (also known as afterbirth) is an organ that connects the developing fetus to the uterine wall to allow nutrient uptake, waste elimination, and gas exchange via the mother's blood supply, fight against internal infection and produce hormones to support pregnancy. The placenta provides oxygen and nutrients to growing babies and removes waste products from the baby's blood.Medical abortion: A medical abortion is a type of non-surgical abortion in which abortifacient pharmaceutical drugs are used to induce abortion. An oral preparation for medical abortion is commonly referred to as an abortion pill.Abdominal pregnancyUterus transplantation: The uterine transplant is the surgical procedure whereby a healthy uterus is transplanted into a female organism of which the uterus is absent or diseased. As part of normal mammalian sexual reproduction, a diseased or absent uterus does not allow normal embryonic implantation, effectively rendering the female infertile.Embryo transfer: Embryo transfer refers to a step in the process of assisted reproduction in which embryos are placed into the uterus of a female with the intent to establish a pregnancy. This technique (which is often used in connection with in vitro fertilization (IVF)), may be used in humans or in animals, in which situations the goals may vary.Natural cycle in vitro fertilization: Natural Cycle IVF is in vitro fertilisation (IVF) using either of the following procedures:Transplacental carcinogenesis: Transplacental carcinogenesis is a series of genotypic and/or phenotypic changes in the cells of a fetus due to in utero exposure to carcinogens. Specifically, these changes are identified as malignant by virtue of their metastatic potential.Birth weight: Birth weight is the body weight of a baby at its birth.Definitions from Georgia Department of Public Health.Selective reduction: Selective reduction (or multifetal pregnancy reduction or MFPR) is the practice of reducing the number of fetuses in a multifetal pregnancy, say quadruplets, to a twin or singleton pregnancy.Gestational hypertensionLower segment Caesarean section: A lower (uterine) segment Caesarean section (LSCS) is the most commonly used type of Caesarean section used today. It includes a transverse cut just above the edge of the bladder and results in less blood loss and is easier to repair than other types of Caesarean sections.Unexplained infertility: Unexplained infertility is infertility that is idiopathic in the sense that its cause remains unknown even after an infertility work-up, usually including semen analysis in the man and assessment of ovulation and fallopian tubes in the woman.merckmanuals > Unexplained Infertility Last full review/revision November 2008 by Robert W.Male lactation: Male lactation in zoology means production of milk from mammary glands in the presence of physiological stimuli connected with nursing infants. It is well documented in the Dayak fruit bat.Decidual reaction: The decidual reaction is the changes in the endometrium of the uterus that prepare it for implantation of an embryo. These changes are observed in each menstrual cycle and enhanced after implantation.Nordli's Cabinet: Nordli's Cabinet governed Norway between 15 January 1976 and 4 February 1981. The Labour Party cabinet was led by Odvar Nordli.National Birth Defects Prevention Network: The National Birth Defects Prevention Network (NBDPN) was founded in 1997. It is a 501(c)3 not-for-profit volunteer organization whose members are involved in birth defects surveillance, prevention and research.Twin reversed arterial perfusionPrenatal diagnosis: Prenatal diagnosis or prenatal screening (note that prenatal diagnosis and prenatal screening refer to two different types of tests) is testing for diseases or conditions in a fetus or embryo before it is born. The aim is to detect birth defects such as neural tube defects, Down syndrome, chromosome abnormalities, genetic disorders and other conditions, such as spina bifida, cleft palate, Tay Sachs disease, sickle cell anemia, thalassemia, cystic fibrosis, Muscular dystrophy, and fragile X syndrome.Equine chorionic gonadotropin: Equine chorionic gonadotropin (eCG) is a gonadotropic hormone produced in the chorion of pregnant mares. Most commonly called pregnant mare's serum gonadotropin (PMSG) in the past, the hormone is commonly used in concert with progestogen to induce ovulation in livestock prior to artificial insemination.International Association of Plastics DistributorsTrophoblast: Trophoblasts (from Greek trephein: to feed, and blastos: germinator) are cells forming the outer layer of a blastocyst, which provide nutrients to the embryo and develop into a large part of the placenta. They are formed during the first stage of pregnancy and are the first cells to differentiate from the fertilized egg.Puerperal disorderEndometrium: The endometrium is the inner mucous membrane of the mammalian uterus.Reproductive technology: Reproductive technology (RT) encompasses all current and anticipated uses of technology in human and animal reproduction, including assisted reproductive technology, contraception and others.QRISK: QRISK2 (the most recent version of QRISK) is a prediction algorithm for cardiovascular disease (CVD) that uses traditional risk factors (age, systolic blood pressure, smoking status and ratio of total serum cholesterol to high-density lipoprotein cholesterol) together with body mass index, ethnicity, measures of deprivation, family history, chronic kidney disease, rheumatoid arthritis, atrial fibrillation, diabetes mellitus, and antihypertensive treatment.Low Fertility Cohorts Study: The Low Fertility Cohorts Study, 1978: A Survey of White, Ever-Married Women Belonging to the 1901-1910 United States Birth Cohorts,Data Sharing For Demographic Research consists of personal interviews of white, ever-married women born between July 1, 1900, and June 30, 1910. In 1978, a national survey of 1,049 married women between the ages of 68 and 78 were interviewed between the months of March and July in order to investigate low fertility during the 1920s and 1930s and the women of childbearing age during those decades.Low birth-weight paradox: The low birth-weight paradox is an apparently paradoxical observation relating to the birth weights and mortality rate of children born to tobacco smoking mothers. Low birth-weight children born to smoking mothers have a lower infant mortality rate than the low birth weight children of non-smokers.Pre-conception counseling: Pre-conception counseling (also called pre-conceptual counseling) is a meeting with a health-care professional (generally a physician) by a woman before attempting to become pregnant. It generally includes a pre-conception risk assessment for any potential complications of pregnancy as well as modifications of risk factors, such as increasing folic acid intake to reduce the risk of neural tube defects and counseling on smoking cessation, alcohol reduction, and medications that may compromise fetal development.Villitis of unknown etiology: Villitis of unknown etiology, abbreviated VUE, is an inflammatory process that involves the chorionic villi (villitis) whose cause (etiology) is not known. VUE is associated with recurrent miscarriage and intrauterine growth restriction, and recurs in subsequent pregnancies.Biocell Center: Biocell Center is an international company specializing in the cryopreservation and private banking of amniotic fluid stem cells. The company is headquartered in Italy with several international locations and is involved with numerous partnerships and research studies of amniotic fluid stem cells,.Global Alliance to Prevent Prematurity and StillbirthMyometrium: The myometrium is the middle layer of the uterine wall, consisting mainly of uterine smooth muscle cells (also called uterine myocytes), but also of supporting stromal and vascular tissue. Its main function is to induce uterine contractions.Contraception, Sterilisation, and Abortion Act 1977: Contraception, Sterilisation, and Abortion Act 1977 is an Act of Parliament in New Zealand. It was passed shortly after the report from the Royal Commission on Contraception, Sterilisation and Abortion.National Birth Control League: The National Birth Control League was a United States organization founded in the early 20th century to promoted the education and use of birth control.

(1/517) Correlates of sexually transmitted bacterial infections among U.S. women in 1995.

CONTEXT: Sexually transmitted diseases (STDs) of bacterial origin such as gonorrhea and chlamydial infection can lead to pelvic inflammatory disease (PID) and infertility. Identifying behaviors and characteristics associated with infection may assist in preventing these often asymptomatic diseases and their sequelae. METHODS: Data from 9,882 sexually active women who participated in the 1995 National Survey of Family Growth describe the characteristics of women who report a history of infection with a bacterial STD or of treatment for PID. Multivariate analysis is used to determine which demographic characteristics and sexual and health-related behaviors affect the likelihood of infection or the occurrence of complications. RESULTS: Overall, 6% of sexually active women reported a history of a bacterial STD, and 8% reported a history of PID. Women who first had sexual intercourse before age 15 were nearly four times as likely to report a bacterial STD, and more than twice as likely to report PID, as were women who first had sex after age 18. Having more than five lifetime sexual partners also was associated with both having an STD and having PID. PID was more common among women reporting a history of a bacterial STD (23%) than among women who reported no such history (7%). In multivariate analyses, age, race, age at first intercourse and lifetime number of sexual partners had a significant effect on the risk of a bacterial STD. Education, age, a history of IUD use, douching and a history of a bacterial STD had a significant impact on the risk of PID, but early onset of intercourse did not, and lifetime number of partners had only a marginal effect. CONCLUSIONS: The pattern of characteristics and behaviors that place women at risk of infection with bacterial STDs is not uniform among groups of women. Further, the level of self-reported PID would suggest higher rates of gonorrhea and chlamydial infection than reported.  (+info)

(2/517) Uterine artery embolization--a successful treatment to control bleeding cervical pregnancy with a simultaneous intrauterine gestation.

A case of a woman suffering from a bleeding heterotopic cervical pregnancy is described. The concurrent cervical pregnancy and intrauterine gestation were diagnosed by ultrasound and bleeding was initially controlled with selective fluoroscopic uterine artery embolization. A selective fetal reduction was done with ultrasound-guided intracardiac potassium chloride. Uterine artery embolization has been used successfully to control haemorrhage in cervical pregnancies when the main goal was to allow preservation of the uterus, thus maintaining potential fertility. This is the first report of arterial embolization used to control bleeding for maintaining a concurrent intrauterine heterotopic pregnancy in an in-vitro fertilization patient. Unfortunately, subsequent conservative measures led to undesired outcome. This procedure initially controlled the bleeding without disrupting the intrauterine fetal cardiac activity.  (+info)

(3/517) Arteriovenous malformation of mesosalpinx associated with a 'vanishing' ectopic pregnancy: diagnosis with three-dimensional color power angiography.

We describe two cases of pelvic arteriovenous malformation diagnosed with the aid of three-dimensional color power angiography. In both cases, beta-human chorionic gonadotropin (beta-hCG) increased to significant levels (8413 and 1560 mIU/ml, respectively); however, neither an intrauterine nor an adnexal gestational sac could be found. In each case, we observed an adnexal mass with several tortuous areas exhibiting abundant turbulent flow. The diagnosis of arteriovenous malformation was made and further assessment by three-dimensional color power angiography and magnetic resonance imaging (MRI) was carried out. The complex vascular anatomy of arteriovenous malformation, including its feeding vessels and drainage, was clearly depicted by three-dimensional color power angiography and correlated well with magnetic resonance angiography. Levels of beta-hCG decreased in subsequent tests, and eventually became negative 2-3 months later without and intervention. We believe that an involutional ectopic pregnancy induced the rapid growth of the arteriovenous malformations within the mesosalpinx. Three-dimensional color power angiography can be performed quickly and easily, using existing ultrasound equipment. It improves our understanding of complicated vasculature, and thus is a useful adjunct to two-dimensional and color Doppler ultrasound in the diagnosis of arteriovenous malformation.  (+info)

(4/517) Lack of sensitivity of endometrial thickness in predicting the presence of an ectopic pregnancy.

The purpose of this study was to evaluate whether endometrial thickness measurements can be used to differentiate between patients with ectopic pregnancy and spontaneous abortion. Of 676 patients with clinical suspicion of ectopic pregnancy, no intrauterine pregnancy was seen in 128. Of these, 42 (33%) had ectopic pregnancy, 52 (40%) had spontaneous abortion, and 34 (27%) had intrauterine pregnancy. No significant difference was found in endometrial thickness between women with ectopic pregnancy (mean, 9.0 mm; range, 2 to 20 mm) and those with spontaneous abortion (mean, 8.4 mm; range, 2 to 18 mm). A thin endometrium seen on transvaginal sonography cannot be used to exclude the diagnosis of ectopic pregnancy.  (+info)

(5/517) Leukocyte populations, hormone receptors and apoptosis in eutopic and ectopic first trimester human pregnancies.

The implantation of trophoblast cells at extrauterine sites still results in decidualization. The objective of the present study was to compare decidualization at eutopic and ectopic implantation sites. Tissues from women undergoing elective termination of uterine pregnancy and from women with ectopic pregnancy were used to detect the presence of cells important for the maintenance of pregnancy, such as BCL-2+, CD56+, CD3+, CD8+ and CD68+ cells, and the presence of oestrogen (ER) and progesterone receptors (PR) by immunohistochemistry. In-situ detection of fragmented DNA was performed to identify apoptotic cells. The percentage of CD3+ cells among all immunocompetent cells in the tubal epithelium was 46.6% (39.9% of CD3+ were also CD8+); the other 53.4% were CD68+ cells. CD56+ cells were undetectable in ectopic decidua at the feto-maternal interface in ectopic tissue. In uterine decidua, we found 29.9% CD3+ cells (2.2% of CD3+ were CD8+), 51.6% CD56+ cells and 18.5% CD68+ cells. The ratio of BCL2+ to CD3+ cells in ectopic pregnancy was 0.41. In uterine pregnancy, the ratio of BCL-2 to CD3 was 0.44 and 0.39 for CD56. Tissues from both ectopic and uterine pregnancies were positive for PR. Fewer apoptotic cell bodies were present in ectopic pregnancy. The use of tissue obtained from ectopic pregnancy may become an excellent model to identify the mechanism of trophoblast invasion in eutopic pregnancies.  (+info)

(6/517) Conservative treatment by angiographic uterine artery embolization of a 12 week cervical ectopic pregnancy.

A 32 year old woman, gravid 1, nulliparous, was admitted to our department at 11 weeks and 2 days of gestation after being diagnosed with cervical pregnancy. She was unsuccessfully treated with methotrexate for 5 days. On the fifth day after admission she underwent bilateral uterine artery angiographic embolization followed by vacuum evacuation and curettage of the cervical canal. A Foley catheter was also inserted in the cervical canal and left in place for 4 days. The patient was discharged in good condition on the seventh postoperative day.  (+info)

(7/517) Cervical pregnancy--a conservative stepwise approach.

A case of cervical pregnancy resistant to intramuscular methotrexate therapy is presented, which was successfully treated by intra-arterial methotrexate followed by selective prophylactic hypogastric artery embolization to avoid aggravating the vaginal bleeding. It is suggested that, in cervical pregnancies in which fertility preservation is desired, a stepwise conservative approach should be applied before resorting to surgical intervention.  (+info)

(8/517) Is perforation of the appendix a risk factor for tubal infertility and ectopic pregnancy? An appraisal of the evidence.

OBJECTIVE: To critically assess the evidence that appendiceal perforation is a risk factor for subsequent tubal infertility or ectopic pregnancy. DATA SOURCES: Epidemiologic studies investigating the relationship between appendectomy and infertility or ectopic pregnancy were identified by searching the MEDLINE database from 1966 to 1997. Appropriate citations were also extracted from a manual search of the bibliographies of selected papers. STUDY SELECTION: Twenty-three articles were retrieved. Only 4 presented original data including comparisons to a nonexposed control group and they form the basis for this study. DATA EXTRACTION: Because the raw data or specific techniques of data analysis were not always explicitly described, indices of risk for exposure were extracted from the data as presented and were analysed without attempting to convert them to a common measure. DATA SYNTHESIS: Articles were assessed according to the criteria of the Evidence-Based Medicine Working Group for evaluating articles on harm. Review of the literature yielded estimates of the risk of adverse fertility outcomes ranging from 1.6 (95% confidence interval [CI] 1.1 to 2.5) for ectopic pregnancy after an appendectomy to 4.8 (95% CI 1.5 to 14.9) for tubal infertility from perforation of the appendix. Recall bias, and poor adjustment for confounding variables in some reports, weakened the validity of the studies. CONCLUSIONS: The methodologic weaknesses of the studies do not permit acceptance of increased risk of tubal pregnancy or infertility as a consequence of perforation of the appendix, so a causal relationship cannot be supported by the data currently available. Only a well-designed case-control study with unbiased ascertainment of exposure and adjustment for confounding variables will provide a definitive answer.  (+info)
