Endometrial oestrogen and progesterone receptors and their relationship to sonographic appearance of the endometrium. (1/352)

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)

Intracytoplasmic sperm injection after follicle stimulation with highly purified human follicle-stimulating hormone compared with human menopausal gonadotropin. (2/352)

PURPOSE: Our purpose was to compare oocyte nuclear maturation and embryo quality after pituitary down-regulation and ovarian stimulation with highly purified follicle-stimulating hormone (FSH) or human menopausal gonadotropin (HMG). METHODS: Fifty-five patients 37 years of age or younger who were undergoing in vitro fertilization (IVF)-intracytoplasmic sperm injection (ICSI) were evaluated retrospectively. In all cases, male factor was the only indication for treatment, with no female-related factors identified. Following pituitary down-regulation, patients were stimulated with hMG (n = 20) or highly purified FSH (n = 35). Main outcome measures included ovarian response to stimulation, oocyte maturity, and ICSI fertilization results. Secondary outcome measures included pregnancy rates and outcome. RESULTS: The ovarian response to stimulation was similar for the two groups, as were the percentage of metaphase II oocytes, fertilization and cleavage rates, and number and quality of transferred and cryopreserved embryos. Cycle outcome was comparable. CONCLUSIONS: In normogonadotropic subjects, monocomponent therapy with highly purified FSH is as effective as hMG in stimulating ovarian follicular development, synchronization of oocyte maturation, and IVF-ICSI outcome. Our findings support the conclusion that the luteinizing hormone component in the stimulation protocol is unnecessary.  (+info)

Endometrial evaluation is not predictive for in vitro fertilization treatment. (3/352)

PURPOSE: The main purpose of this study was to evaluate ovarian function by clomiphene citrate (CC) challenge test in a group of tubal infertile women and to study endometrial morphological maturation in the early luteal phase of CC-stimulated cycles as compared to in vitro fertilization (IVF) treatment outcome. METHODS AND RESULTS: Four women presented with strongly retarded, proliferative endometrium in the luteal phase. Of these, three presented with impaired ovarian function, high basal follicle-stimulating hormone, and high follicle-stimulating hormone levels after clomiphene stimulation on cycle day 10. In the remaining 30 women, showing an in-phase endometrium after CC stimulation, a comparison of six morphological characteristics did not reveal any significant differences between the 14 women who did become pregnant and the 16 who did not. No significant differences in endometrial thickness were observed between the groups. Significant differences were found when comparing estradiol and progesterone area under the curve during the luteal phase (P < 0.001 and P < 0.01, respectively) between those who did and those who did not become pregnant. CONCLUSIONS: Luteal endometrium morphology was not a sharp instrument to detect differences between women who did and women who did not become pregnant following IVF treatment, while ovarian function, as measured by hormonal markers, seemed to be a more reliable prognostic factor for IVF treatment outcome.  (+info)

A comparison of three gonadotrophin-releasing hormone analogues in an in-vitro fertilization programme: a prospective randomized study. (4/352)

The use of gonadotrophin-releasing hormone analogues (GnRHa) has resulted in improved pregnancy rates in in-vitro fertilization (IVF) treatment cycles. Traditionally, short-acting analogues have been employed because of concerns over long-acting depot preparations causing profound suppression and luteal phase defects adversely affecting pregnancy and miscarriage rates. We randomized 60 IVF patients to receive a short-acting GnRHa, nafarelin or buserelin, or to receive a depot formulation, leuprorelin, all commenced in the early follicular phase and compared their effects on hormonal suppression and clinical outcome. We found that on day 15 of administration there was a significant difference in the suppression of oestradiol from initial concentrations, when patients on buserelin were compared with patients on nafarelin or leuprorelin (54 versus 72 and 65%; P < 0.05) and also in the number of patients satisfactorily suppressed, (80 versus 90 and 90%; P < 0.05), though there were no differences between the analogues by day 21. Similarly there was no difference in hormonal suppression during the stimulation phase or in implantation, pregnancy or miscarriage rates in comparing the three agonists. We conclude that with nafarelin and leuprorelin, stimulation with gonadotrophins may begin after 2 weeks of suppression and that long-acting GnRHa are as effective as short-acting analogues with no detrimental effects on the luteal phase.  (+info)

Evaluation of hypothalamic-pituitary-adrenal axis in amenorrhoeic women with insulin-dependent diabetes. (5/352)

Diabetes is associated with a higher incidence of secondary hypogonadotrophic amenorrhoea. In amenorrhoeic women with insulin-dependent diabetes a derangement in hypothalamic-pituitary-ovary axis has been proposed. No data exist on hypothalamic-pituitary-adrenal function in these women. Gonadotrophin releasing hormone (GnRH), corticotrophin releasing hormone (CRH), metoclopramide and thyroid releasing hormone (TRH) tests were performed in 15 diabetic women, eight amenorrhoeic (AD) and seven eumenorrhoeic (ED). Frequent blood samples were taken during 24 h to evaluate cortisol plasma concentrations. There were no differences between the groups in body mass index, duration of diabetes, insulin dose and metabolic control. The AD women had lower plasma concentrations of luteinizing hormone (LH), follicle stimulating hormone (FSH), prolactin, oestradiol, androstenedione and 17-hydroxyprogesterone (17-OHP) than the ED women. The responses of pituitary gonadotrophins to GnRH, and of thyroid stimulating hormone (TSH) to TRH, were similar in both groups. The AD women had a lower prolactin response to TRH and metoclopramide, and lower ACTH and cortisol responses to CRH, than the ED women. Mean cortisol concentrations > 24 h were higher in the amenorrhoeic group. Significant differences in cortisol concentrations from 2400 to 1000 h were found between the two groups. Insulin-dependent diabetes may involve mild chronic hypercortisolism which may affect metabolic control. Stress-induced activation of the hypothalamic-pituitary-adrenal axis would increase hypothalamic secretion of CRH. This would lead directly and perhaps also indirectly by increasing dopaminergic tonus to inhibition of GnRH secretion and hence hypogonadotrophic amenorrhoea. Amenorrhoea associated with metabolically controlled insulin-dependent diabetes is a form of functional hypothalamic amenorrhoea that requires pharmacological and psychological management.  (+info)

Is there a difference in the function of granulosa-luteal cells in patients undergoing in-vitro fertilization either with gonadotrophin-releasing hormone agonist or gonadotrophin-releasing hormone antagonist? (6/352)

Gonadotrophin-releasing hormone (GnRH) regulates gonadotrophin release. It has been shown that GnRH may have a direct effect on the ovary, as the addition of GnRH to granulosa cell cultures inhibits the production of progesterone and oestradiol. Specific GnRH receptors have been found to be present in rat and human granulosa cells. Desensitization of the pituitary by GnRH agonist has become common in in-vitro fertilization (IVF) treatment, usually by a long protocol of 2-3 weeks. With the introduction of GnRH antagonists, which produce an immediate blockage of the GnRH receptors, a much shorter exposure is needed of 3-6 days. The aim of this study was to evaluate the effect of a GnRH agonist (buserelin) and a GnRH antagonist (cetrorelix) on the function of granulosa cells cultured in vitro from IVF patients. Women were treated by IVF randomized either to have buserelin nasal spray from the luteal phase in the previous cycle or cetrorelix from day 6 of the cycle. Both groups had ovarian stimulation with human menopausal gonadotrophin (HMG) 150 IU daily, i.e. HCG was administered when the follicles were larger than 17 mm, and aspirated 36 h later. Granulosa cells, separated and washed from large follicles containing ova, were pooled. After 48 h of pre-incubation, the granulosa cells were cultured for 4 days in medium with either added testosterone or cAMP with or without HCG, with change of medium after 2 days. The progesterone and oestradiol concentrations in the culture medium were measured by immunological assay, and cellular protein was measured by microprotein assay. The results showed that granulosa cells from women treated with GnRH antagonist (cetrorelix) responded earlier to the in-vitro hormone stimulation in terms of progesterone accumulation than women treated with the GnRH agonist (buserelin). This may have been due to difference in time of exposure to the analogue. The results may indicate that the luteal function is less impaired in GnRH antagonist treatment than in GnRH agonist treatment.  (+info)

The value of basal serum follicle stimulating hormone, luteinizing hormone and oestradiol concentrations following pituitary down-regulation in predicting ovarian response to stimulation with highly purified follicle stimulating hormone. (7/352)

The value of gonadotrophin and oestradiol concentrations following pituitary down-regulation with leuprolide acetate in predicting ovarian response to stimulation was evaluated in three groups of women undergoing ovarian stimulation for in-vitro fertilization with highly purified follicle stimulating hormone (FSH). Leuprolide acetate was started in the midluteal phase, and either stopped at menses (IVF-SL group, n = 3), or continued throughout stimulation (IVF-LL group, n = 38; oocyte donors, n = 58). Ovarian stimulation was started on cycle day 3, after blood was drawn for down-regulated FSH, luteinizing hormone (LH) and oestradiol. Higher down-regulated LH was predictive of higher oestradiol on day 5 of stimulation in both IVF groups, and of need for fewer ampoules in the IVF-LL group, but not of oestradiol on day of human chorionic gonadotrophin (HCG) administration or number of oocytes retrieved. Higher FSH after down-regulation predicted yield of fewer oocytes in the donor and IVF-LL groups, and higher oestradiol on day 5 of stimulation, need for fewer ampoules and a shorter duration of therapy in both IVF groups. Higher oestradiol after down-regulation was associated with higher oestradiol on day 5 of stimulation and on day of HCG administration, a shorter duration of therapy and need for fewer ampoules in all groups. Whereas these results do not ascribe any predictive significance to LH, they suggest that oestradiol and FSH concentrations after down-regulation are predictive of the pattern of ovarian response to stimulation and of oocyte yield.  (+info)

Anovulations in an ovary during two menstrual cycles enhance the pregnancy potential of oocytes matured in that ovary during the following third cycle. (8/352)

The aim of this study was to test whether ovulation from an ovary affects the health of oocytes from dominant follicles in that ovary two cycles later. A total of 80 women each with two intact ovaries underwent 270 treatment cycles (155 natural cycles and 115 clomiphene citrate cycles) all showing unilateral ovulation. The results from the in-vitro fertilization (IVF) treatment were grouped according to whether ovulation (O) or anovulation (A) (no ovulation) was observed in the ovary with dominant follicle during the treatment cycle in the previous two cycles: O-O, A-O, O-A and A-A (previous second cycle-previous first cycle). The rate of pre-embryo formation in A-A was significantly higher than that of O-A. The pregnancy rate in A-A (29%) was also higher than those of O-A (13%), A-O (9%) and O-O (5%). These rates increased from O-O to A-A as the number of previous ovulations in an ovary decreased. The presence of a corpus luteum and/or a dominant follicle is likely to exert local negative effects on the health of the oocyte contained in the follicle selected to ovulate up to two cycles later. Anovulations in an ovary for two menstrual cycles may therefore provide improved conditions for the development of a healthier oocyte with an increased pregnancy potential.  (+info)

Fertility agents for males are medications or supplements that are used to improve male fertility. They can work by increasing sperm count, improving sperm motility (movement), and enhancing overall sperm quality. Some examples of male fertility agents include:

1. Clomiphene citrate: This medication is typically used to treat infertility in women, but it can also be prescribed off-label for men with low sperm counts. It works by stimulating the production of follicle-stimulating hormone (FSH) and luteinizing hormone (LH), which are important for sperm production.
2. Gonadotropins: These are hormones that can be given as injections to stimulate the testicles to produce more testosterone and sperm. Human chorionic gonadotropin (hCG) and human menopausal gonadotropin (hMG) are examples of gonadotropins used for male fertility treatment.
3. Antioxidants: Certain antioxidant supplements, such as vitamin C, vitamin E, coenzyme Q10, and L-carnitine, have been shown to improve sperm quality by reducing oxidative stress and DNA damage in sperm cells.
4. Herbal supplements: Some herbs, such as tribulus terrestris, maca root, and ashwagandha, are believed to boost male fertility by increasing testosterone levels and improving sperm count and motility. However, their effectiveness is not well-established, and they should be used with caution under the guidance of a healthcare provider.
5. Varicocele repair: In some cases, a varicocele (dilated vein in the scrotum) can contribute to male infertility by increasing the temperature around the testicles and impairing sperm production. Surgical repair of a varicocele may be recommended to improve fertility.

It is important to consult with a healthcare provider before starting any fertility treatment, as these agents may have side effects or interact with other medications. A thorough evaluation of male fertility factors, such as hormone levels, semen analysis, and physical examination, should be performed to determine the most appropriate treatment approach.

Fertility agents, also known as fertility drugs or medications, are substances that are used to enhance or restore fertility in individuals who are having difficulty conceiving a child. These agents work by affecting various aspects of the reproductive system, such as stimulating ovulation, enhancing sperm production, or improving the quality and quantity of eggs produced by the ovaries.

There are several types of fertility agents available, including:

1. Ovulation Inducers: These medications are used to stimulate ovulation in women who do not ovulate regularly or at all. Examples include clomiphene citrate (Clomid) and letrozole (Femara).
2. Gonadotropins: These hormones are administered to stimulate the ovaries to produce multiple eggs during a single menstrual cycle. Examples include human menopausal gonadotropin (hMG), follicle-stimulating hormone (FSH), and luteinizing hormone (LH).
3. Inhibins: These medications are used to prevent premature ovulation and improve the quality of eggs produced by the ovaries. Examples include ganirelix acetate and cetrorelix acetate.
4. Sperm Motility Enhancers: These medications are used to improve sperm motility in men with low sperm count or poor sperm movement. Examples include pentoxifylline and caffeine.
5. Fertility Preservation Medications: These medications are used to preserve fertility in individuals who are undergoing treatments that may affect their reproductive system, such as chemotherapy or radiation therapy. Examples include gonadotropin-releasing hormone agonists (GnRH) and cryopreservation of sperm, eggs, or embryos.

It is important to note that fertility agents can have side effects and should only be used under the guidance of a healthcare professional. It is also essential to discuss any underlying medical conditions, allergies, and potential risks before starting any fertility treatment.

Fertility is the natural ability to conceive or to cause conception of offspring. In humans, it is the capacity of a woman and a man to reproduce through sexual reproduction. For women, fertility usually takes place during their reproductive years, which is from adolescence until menopause. A woman's fertility depends on various factors including her age, overall health, and the health of her reproductive system.

For men, fertility can be affected by a variety of factors such as age, genetics, general health, sexual function, and environmental factors that may affect sperm production or quality. Factors that can negatively impact male fertility include exposure to certain chemicals, radiation, smoking, alcohol consumption, drug use, and sexually transmitted infections (STIs).

Infertility is a common medical condition affecting about 10-15% of couples trying to conceive. Infertility can be primary or secondary. Primary infertility refers to the inability to conceive after one year of unprotected sexual intercourse, while secondary infertility refers to the inability to conceive following a previous pregnancy.

Infertility can be treated with various medical and surgical interventions depending on the underlying cause. These may include medications to stimulate ovulation, intrauterine insemination (IUI), in vitro fertilization (IVF), or surgery to correct anatomical abnormalities.

Female fertility agents are medications or treatments that are used to enhance or restore female fertility. They can work in various ways such as stimulating ovulation, improving the quality of eggs, facilitating the implantation of a fertilized egg in the uterus, or addressing issues related to the reproductive system.

Some examples of female fertility agents include:

1. Clomiphene citrate (Clomid, Serophene): This medication stimulates ovulation by causing the pituitary gland to release more follicle-stimulating hormone (FSH) and luteinizing hormone (LH).
2. Gonadotropins: These are hormonal medications that contain FSH and LH, which stimulate the ovaries to produce mature eggs. Examples include human menopausal gonadotropin (hMG) and follicle-stimulating hormone (FSH).
3. Letrozole (Femara): This medication is an aromatase inhibitor that can be used off-label to stimulate ovulation in women who do not respond to clomiphene citrate.
4. Metformin (Glucophage): This medication is primarily used to treat type 2 diabetes, but it can also improve fertility in women with polycystic ovary syndrome (PCOS) by regulating insulin levels and promoting ovulation.
5. Bromocriptine (Parlodel): This medication is used to treat infertility caused by hyperprolactinemia, a condition characterized by high levels of prolactin in the blood.
6. Assisted reproductive technologies (ART): These include procedures such as in vitro fertilization (IVF), intracytoplasmic sperm injection (ICSI), and gamete intrafallopian transfer (GIFT). They involve manipulating eggs and sperm outside the body to facilitate fertilization and implantation.

It is important to consult with a healthcare provider or reproductive endocrinologist to determine the most appropriate fertility agent for individual needs, as these medications can have side effects and potential risks.

Fertility preservation is a medical procedure or treatment that is aimed at protecting and preserving the reproductive function and potential of an individual, typically before undergoing medical treatments that can potentially compromise their fertility. This may involve the cryopreservation (freezing) and storage of gametes (sperm or eggs), embryos, or reproductive tissues, such as ovarian or testicular tissue, for future use.

Fertility preservation is often recommended for individuals who are facing medical treatments that can have a negative impact on their fertility, such as chemotherapy, radiation therapy, or surgical removal of reproductive organs. It may also be considered for individuals with conditions that can affect their fertility, such as certain genetic disorders or autoimmune diseases.

The goal of fertility preservation is to allow individuals to have biological children in the future, even if their fertility is compromised by medical treatments or conditions. The success of fertility preservation depends on several factors, including the age and health of the individual at the time of preservation, the type and duration of the medical treatment, and the quality of the preserved gametes or tissues.

Female infertility is a condition characterized by the inability to conceive after 12 months or more of regular, unprotected sexual intercourse or the inability to carry a pregnancy to a live birth. The causes of female infertility can be multifactorial and may include issues with ovulation, damage to the fallopian tubes or uterus, endometriosis, hormonal imbalances, age-related factors, and other medical conditions.

Some common causes of female infertility include:

1. Ovulation disorders: Conditions such as polycystic ovary syndrome (PCOS), thyroid disorders, premature ovarian failure, and hyperprolactinemia can affect ovulation and lead to infertility.
2. Damage to the fallopian tubes: Pelvic inflammatory disease, endometriosis, or previous surgeries can cause scarring and blockages in the fallopian tubes, preventing the egg and sperm from meeting.
3. Uterine abnormalities: Structural issues with the uterus, such as fibroids, polyps, or congenital defects, can interfere with implantation and pregnancy.
4. Age-related factors: As women age, their fertility declines due to a decrease in the number and quality of eggs.
5. Other medical conditions: Certain medical conditions, such as diabetes, celiac disease, and autoimmune disorders, can contribute to infertility.

In some cases, female infertility can be treated with medications, surgery, or assisted reproductive technologies (ART) like in vitro fertilization (IVF). A thorough evaluation by a healthcare professional is necessary to determine the underlying cause and develop an appropriate treatment plan.

Infertility is a reproductive health disorder defined as the failure to achieve a clinical pregnancy after 12 months or more of regular, unprotected sexual intercourse or due to an impairment of a person's capacity to reproduce either as an individual or with their partner. It can be caused by various factors in both men and women, including hormonal imbalances, structural abnormalities, genetic issues, infections, age, lifestyle factors, and others. Infertility can have significant emotional and psychological impacts on individuals and couples experiencing it, and medical intervention may be necessary to help them conceive.

Male infertility is a condition characterized by the inability to cause pregnancy in a fertile female. It is typically defined as the failure to achieve a pregnancy after 12 months or more of regular unprotected sexual intercourse.

The causes of male infertility can be varied and include issues with sperm production, such as low sperm count or poor sperm quality, problems with sperm delivery, such as obstructions in the reproductive tract, or hormonal imbalances that affect sperm production. Other factors that may contribute to male infertility include genetic disorders, environmental exposures, lifestyle choices, and certain medical conditions or treatments.

It is important to note that male infertility can often be treated or managed with medical interventions, such as medication, surgery, or assisted reproductive technologies (ART). A healthcare provider can help diagnose the underlying cause of male infertility and recommend appropriate treatment options.

Reproduction, in the context of biology and medicine, refers to the process by which organisms produce offspring. It is a complex process that involves the creation, development, and growth of new individuals from parent organisms. In sexual reproduction, this process typically involves the combination of genetic material from two parents through the fusion of gametes (sex cells) such as sperm and egg cells. This results in the formation of a zygote, which then develops into a new individual with a unique genetic makeup.

In contrast, asexual reproduction does not involve the fusion of gametes and can occur through various mechanisms such as budding, fragmentation, or parthenogenesis. Asexual reproduction results in offspring that are genetically identical to the parent organism.

Reproduction is a fundamental process that ensures the survival and continuation of species over time. It is also an area of active research in fields such as reproductive medicine, where scientists and clinicians work to understand and address issues related to human fertility, contraception, and genetic disorders.

Spermatozoa are the male reproductive cells, or gametes, that are produced in the testes. They are microscopic, flagellated (tail-equipped) cells that are highly specialized for fertilization. A spermatozoon consists of a head, neck, and tail. The head contains the genetic material within the nucleus, covered by a cap-like structure called the acrosome which contains enzymes to help the sperm penetrate the female's egg (ovum). The long, thin tail propels the sperm forward through fluid, such as semen, enabling its journey towards the egg for fertilization.

The birth rate is the number of live births that occur in a population during a specific period, usually calculated as the number of live births per 1,000 people per year. It is an important demographic indicator used to measure the growth or decline of a population over time. A higher birth rate indicates a younger population and faster population growth, while a lower birth rate suggests an older population and slower growth.

The birth rate can be affected by various factors, including socioeconomic conditions, cultural attitudes towards childbearing, access to healthcare services, and government policies related to family planning and reproductive health. It is also influenced by the age structure of the population, as women in their reproductive years (typically ages 15-49) are more likely to give birth.

It's worth noting that while the birth rate is an important indicator of population growth, it does not provide a complete picture of fertility rates or demographic trends. Other measures, such as the total fertility rate (TFR), which estimates the average number of children a woman would have during her reproductive years, are also used to analyze fertility patterns and population dynamics.

Pregnancy is a physiological state or condition where a fertilized egg (zygote) successfully implants and grows in the uterus of a woman, leading to the development of an embryo and finally a fetus. This process typically spans approximately 40 weeks, divided into three trimesters, and culminates in childbirth. Throughout this period, numerous hormonal and physical changes occur to support the growing offspring, including uterine enlargement, breast development, and various maternal adaptations to ensure the fetus's optimal growth and well-being.

Female genitalia refer to the reproductive and sexual organs located in the female pelvic region. They are primarily involved in reproduction, menstruation, and sexual activity. The external female genitalia, also known as the vulva, include the mons pubis, labia majora, labia minora, clitoris, and the external openings of the urethra and vagina. The internal female genitalia consist of the vagina, cervix, uterus, fallopian tubes, and ovaries. These structures work together to facilitate menstruation, fertilization, pregnancy, and childbirth.

Sperm motility is the ability of sperm to move actively and effectively through the female reproductive tract towards the egg for fertilization. It is typically measured as the percentage of moving sperm in a sample, and their progressiveness or velocity. Normal human sperm motility is generally defined as forward progression of at least 25 micrometers per second, with at least 50% of sperm showing progressive motility. Reduced sperm motility, also known as asthenozoospermia, can negatively impact fertility and reproductive outcomes.

Reproductive behavior, in the context of medical and biological sciences, refers to the actions or behaviors associated with an organism's reproduction. This can include various aspects such as:

1. Mating rituals or courtship behaviors that individuals of a species engage in to attract mates.
2. Copulation or actual mating process.
3. Parental care, which is the behavior of parents towards their offspring, including protection, feeding, and teaching necessary skills.
4. In some cases, it may also include aggressive behaviors related to territory defense for breeding.

These behaviors are influenced by hormonal changes, genetic factors, environmental conditions, and individual experiences. They vary widely among different species, with some displaying complex rituals while others have more straightforward processes.

In humans, reproductive behavior includes sexual activities associated with procreation, contraceptive use, family planning, and sometimes abstinence. It's important to note that human reproductive behavior can also be influenced by cultural, psychological, and social factors, making it quite complex compared to many other species.

Sperm count, also known as sperm concentration, is the number of sperm present in a given volume of semen. The World Health Organization (WHO) previously defined a normal sperm count as at least 20 million sperm per milliliter of semen. However, more recent studies suggest that fertility may be affected even when sperm counts are slightly lower than this threshold. It's important to note that sperm count is just one factor among many that can influence male fertility. Other factors, such as sperm motility (the ability of sperm to move properly) and morphology (the shape of the sperm), also play crucial roles in successful conception.

Sexual behavior in animals refers to a variety of behaviors related to reproduction and mating that occur between members of the same species. These behaviors can include courtship displays, mating rituals, and various physical acts. The specific forms of sexual behavior displayed by a given species are influenced by a combination of genetic, hormonal, and environmental factors.

In some animals, sexual behavior is closely tied to reproductive cycles and may only occur during certain times of the year or under specific conditions. In other species, sexual behavior may be more frequent and less closely tied to reproduction, serving instead as a means of social bonding or communication.

It's important to note that while humans are animals, the term "sexual behavior" is often used in a more specific sense to refer to sexual activities between human beings. The study of sexual behavior in animals is an important area of research within the field of animal behavior and can provide insights into the evolutionary origins of human sexual behavior as well as the underlying mechanisms that drive it.

An ovary is a part of the female reproductive system in which ova or eggs are produced through the process of oogenesis. They are a pair of solid, almond-shaped structures located one on each side of the uterus within the pelvic cavity. Each ovary measures about 3 to 5 centimeters in length and weighs around 14 grams.

The ovaries have two main functions: endocrine (hormonal) function and reproductive function. They produce and release eggs (ovulation) responsible for potential fertilization and development of an embryo/fetus during pregnancy. Additionally, they are essential in the production of female sex hormones, primarily estrogen and progesterone, which regulate menstrual cycles, sexual development, and reproduction.

During each menstrual cycle, a mature egg is released from one of the ovaries into the fallopian tube, where it may be fertilized by sperm. If not fertilized, the egg, along with the uterine lining, will be shed, leading to menstruation.

Assisted reproductive techniques (ART) are medical procedures that involve the handling of human sperm and ova to establish a pregnancy. These techniques are used when other methods of achieving pregnancy have failed or are not available. Examples of ART include in vitro fertilization (IVF), intracytoplasmic sperm injection (ICSI), gamete intrafallopian transfer (GIFT), and zygote intrafallopian transfer (ZIFT). These procedures may be used to treat infertility, prevent genetic disorders, or to help same-sex couples or single people have children. It is important to note that the use of ART can involve significant physical, emotional, and financial costs, and it may not always result in a successful pregnancy.

The testis, also known as the testicle, is a male reproductive organ that is part of the endocrine system. It is located in the scrotum, outside of the abdominal cavity. The main function of the testis is to produce sperm and testosterone, the primary male sex hormone.

The testis is composed of many tiny tubules called seminiferous tubules, where sperm are produced. These tubules are surrounded by a network of blood vessels, nerves, and supportive tissues. The sperm then travel through a series of ducts to the epididymis, where they mature and become capable of fertilization.

Testosterone is produced in the Leydig cells, which are located in the interstitial tissue between the seminiferous tubules. Testosterone plays a crucial role in the development and maintenance of male secondary sexual characteristics, such as facial hair, deep voice, and muscle mass. It also supports sperm production and sexual function.

Abnormalities in testicular function can lead to infertility, hormonal imbalances, and other health problems. Regular self-examinations and medical check-ups are recommended for early detection and treatment of any potential issues.

Artificial insemination (AI) is a medical procedure that involves the introduction of sperm into a female's cervix or uterus for the purpose of achieving pregnancy. This procedure can be performed using sperm from a partner or a donor. It is often used when there are issues with male fertility, such as low sperm count or poor sperm motility, or in cases where natural conception is not possible due to various medical reasons.

There are two types of artificial insemination: intracervical insemination (ICI) and intrauterine insemination (IUI). ICI involves placing the sperm directly into the cervix, while IUI involves placing the sperm directly into the uterus using a catheter. The choice of procedure depends on various factors, including the cause of infertility and the preferences of the individuals involved.

Artificial insemination is a relatively simple and low-risk procedure that can be performed in a doctor's office or clinic. It may be combined with fertility drugs to increase the chances of pregnancy. The success rate of artificial insemination varies depending on several factors, including the age and fertility of the individuals involved, the cause of infertility, and the type of procedure used.

Semen is a complex, whitish fluid that is released from the male reproductive system during ejaculation. It is produced by several glands, including the seminal vesicles, prostate gland, and bulbourethral glands. Semen contains several components, including sperm (the male reproductive cells), as well as various proteins, enzymes, vitamins, and minerals. Its primary function is to transport sperm through the female reproductive tract during sexual intercourse, providing nutrients and aiding in the protection of the sperm as they travel toward the egg for fertilization.

Spermatogenesis is the process by which sperm cells, or spermatozoa, are produced in male organisms. It occurs in the seminiferous tubules of the testes and involves several stages:

1. Spermatocytogenesis: This is the initial stage where diploid spermatogonial stem cells divide mitotically to produce more spermatogonia, some of which will differentiate into primary spermatocytes.
2. Meiosis: The primary spermatocytes undergo meiotic division to form haploid secondary spermatocytes, which then divide again to form haploid spermatids. This process results in the reduction of chromosome number from 46 (diploid) to 23 (haploid).
3. Spermiogenesis: The spermatids differentiate into spermatozoa, undergoing morphological changes such as the formation of a head and tail. During this stage, most of the cytoplasm is discarded, resulting in highly compacted and streamlined sperm cells.
4. Spermation: The final stage where mature sperm are released from the seminiferous tubules into the epididymis for further maturation and storage.

The entire process takes approximately 72-74 days in humans, with continuous production throughout adulthood.

Cryopreservation is a medical procedure that involves the preservation of cells, tissues, or organs by cooling them to very low temperatures, typically below -150°C. This is usually achieved using liquid nitrogen. The low temperature slows down or stops biological activity, including chemical reactions and cellular metabolism, which helps to prevent damage and decay.

The cells, tissues, or organs that are being cryopreserved must be treated with a cryoprotectant solution before cooling to prevent the formation of ice crystals, which can cause significant damage. Once cooled, the samples are stored in specialized containers or tanks until they are needed for use.

Cryopreservation is commonly used in assisted reproductive technologies, such as the preservation of sperm, eggs, and embryos for fertility treatments. It is also used in research, including the storage of cell lines and stem cells, and in clinical settings, such as the preservation of skin grafts and corneas for transplantation.

"Sex characteristics" refer to the anatomical, chromosomal, and genetic features that define males and females. These include both primary sex characteristics (such as reproductive organs like ovaries or testes) and secondary sex characteristics (such as breasts or facial hair) that typically develop during puberty. Sex characteristics are primarily determined by the presence of either X or Y chromosomes, with XX individuals usually developing as females and XY individuals usually developing as males, although variations and exceptions to this rule do occur.
