Cyst due to the occlusion of the duct of a follicle or small gland.
General term for CYSTS and cystic diseases of the OVARY.
Any fluid-filled closed cavity or sac that is lined by an EPITHELIUM. Cysts can be of normal, abnormal, non-neoplastic, or neoplastic tissues.
Cysts found in the jaws and arising from epithelium involved in tooth formation. They include follicular cysts (e.g., primordial cyst, dentigerous cyst, multilocular cyst), lateral periodontal cysts, and radicular cysts. They may become keratinized (odontogenic keratocysts). Follicular cysts may give rise to ameloblastomas and, in rare cases, undergo malignant transformation.
Hormones produced by the GONADS, including both steroid and peptide hormones. The major steroid hormones include ESTRADIOL and PROGESTERONE from the OVARY, and TESTOSTERONE from the TESTIS. The major peptide hormones include ACTIVINS and INHIBINS.
An immature epithelial tumor of the JAW originating from the epithelial rests of Malassez or from other epithelial remnants of the ENAMEL from the developmental period. It is a slowly growing tumor, usually benign, but displays a marked propensity for invasive growth.
Diseases of domestic cattle of the genus Bos. It includes diseases of cows, yaks, and zebus.
The discharge of an OVUM from a rupturing follicle in the OVARY.
Liquid material found in epithelial-lined closed cavities or sacs.
An OOCYTE-containing structure in the cortex of the OVARY. The oocyte is enclosed by a layer of GRANULOSA CELLS providing a nourishing microenvironment (FOLLICULAR FLUID). The number and size of follicles vary depending on the age and reproductive state of the female. The growing follicles are divided into five stages: primary, secondary, tertiary, Graafian, and atretic. Follicular growth and steroidogenesis depend on the presence of GONADOTROPINS.
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.
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.
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.
The 17-beta-isomer of estradiol, an aromatized C18 steroid with hydroxyl group at 3-beta- and 17-beta-position. Estradiol-17-beta is the most potent form of mammalian estrogenic steroids.
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.
Domesticated bovine animals of the genus Bos, usually kept on a farm or ranch and used for the production of meat or dairy products or for heavy labor.
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 fluid surrounding the OVUM and GRANULOSA CELLS in the Graafian follicle (OVARIAN FOLLICLE). The follicular fluid contains sex steroids, glycoprotein hormones, plasma proteins, mucopolysaccharides, and enzymes.
Intradermal or subcutaneous saclike structure, the wall of which is stratified epithelium containing keratohyalin granules.
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. Inhibins consist of a disulfide-linked heterodimer with a unique alpha linked to either a beta A or a beta B subunit to form inhibin A or inhibin B, respectively

High concentrations of the vascular endothelial growth factor and interleukin-8 in ovarian endometriomata. (1/39)

Patients with endometriosis are characterized by the ability of the endometrium to implant and by the peritoneal response to the tissue; angiogenic factors may play a significant role in the aetiology of endometriosis supporting the implantation of ectopic endometrial cells. Vascular endothelial growth factor (VEGF) is a mitogen, morphogen and chemoactractant for endothelial cells and, in vivo, it is a powerful mediator for vessel permeability. Interleukin-8 (IL-8) is a chemoatractant for neutrophils and is a potent angiogenic factor. Women (n = 20) with ovarian endometriomata and 10 women with follicular cysts were enrolled in this study to investigate the role of VEGF and IL-8 in the development and maintenance of ovarian endometriomata. Cystic fluids were collected by laparoscopy, immediately centrifuged and stored until the enzyme-linked immunosorbent assays were performed. The VEGF and IL-8 concentrations were found to be significantly higher in the fluids of the ovarian endometriomata than in those of the follicular cysts of controls (P < 0.001 and P < 0.001 respectively); in addition, a significant inverse correlation between the VEGF cystic fluid concentrations and the diameter of the endometriotic adnexal masses was found (r = -0.56, P = 0.01). The evidence that the high concentrations of VEGF and IL-8 are present in the ovarian endometriomata indicates that angiogenesis could be a specific event both for the progression and maintenance of such cysts.  (+info)

Dominant bovine ovarian follicular cysts express increased levels of messenger RNAs for luteinizing hormone receptor and 3 beta-hydroxysteroid dehydrogenase delta(4),delta(5) isomerase compared to normal dominant follicles. (2/39)

The objective was to compare ovarian steroids and expression of mRNAs encoding cytochrome P450 side-chain cleavage, cytochrome P450 17 alpha-hydroxylase, cytochrome P450 aromatase, 3 beta-hydroxysteroid dehydrogenase Delta(4),Delta(5) isomerase, LH, and FSH receptors and estrogen receptor-beta in ovaries of cows with dominant and nondominant ovarian follicular cysts and in normal dominant follicles. Estradiol-17 beta, progesterone, and androstenedione concentrations were determined in follicular fluid using specific RIAs. Dominant cysts were larger than young cysts or dominant follicles, whereas nondominant cysts were intermediate. Estradiol-17 beta (ng/ml) and total steroids (ng/follicle) were higher in dominant cysts than in dominant follicles. Expression of LH receptor and 3 beta-hydroxysteroid dehydrogenase mRNAs was higher in granulosa cells of dominant cysts than in dominant follicles. Nondominant cysts had higher follicular concentrations of progesterone, lower estradiol-17 beta concentrations, and lower expression of steroidogenic enzyme, gonadotropin receptor, and estrogen receptor-beta mRNAs than other groups. In summary, increased expression of LH receptor and 3 beta-hydroxysteroid dehydrogenase mRNAs in granulosa and increased follicular estradiol-17 beta concentrations were associated with dominant cysts compared to dominant follicles. Study of cysts at known developmental stages is useful in identifying alterations in follicular steroidogenesis.  (+info)

Serous cysts are a benign component of the cyclic ovary in the guinea pig with an incidence dependent upon inhibin bioactivity. (3/39)

Ovaries were collected from normal cycling female guinea pigs on each day of the estrous cycle (n = 5 per day) for histological analysis of ovarian morphology. Three types of ovarian cysts were observed: serous cysts, follicular cysts and parovarian cysts. The most common were serous cysts (cystic rete ovarii), which were present throughout the estrous cycle with an overall incidence of 63.5% (54 out of 85 animals). Follicular cysts occurred in 22.4% of guinea pigs overall (19 out of 85). Only one parovarian cyst (1 out of 85) was observed in the present experiment. Follicular cysts always coincided with serous cysts and were less common during diestrus. The incidence of serous cysts did not vary significantly across the estrous cycle. In a second experiment, cycling female guinea pigs were arrested in a prolonged luteal phase by a progesterone implant in order to achieve ovarian synchrony. They were then treated with inhibin antiserum (0.5 or 1 ml per animal i.v.; n = 6 per group) or normal goat serum (controls; n = 6 per group). There was a dose dependent increase in the incidence of serous ovarian cysts following passive immunization against the inhibin alpha-subunit. These results suggest that serous cysts are a normal component of the cyclic guinea pig ovary and that alterations in the inhibin-follicle-stimulating hormone system appear to modulate the incidence of serous ovarian cysts in this species.  (+info)

Relationship among insulin-like growth factor-I, blood metabolites and postpartum ovarian function in dairy cows. (4/39)

The relationship among nutritional status, systemic insulin-like growth factor-I (IGF-I) and ovarian function early postpartum were investigated. A total of 27 Holstein-Friesian cows, 10 that cycled normally within 20 days postpartum, 5 diagnosed with follicular cysts, 8 with persistent corpus luteum (CL) after the first ovulation postpartum and 4 with inactive ovaries were used for the study. Blood samples were collected 1-3 times per week, for 60 days pre- and postpartum, for IGF-I, progesterone, estradiol, free fatty acids (FFA), blood urea nitrogen (BUN), and aspartate aminotransferase (AST) determination. Inactive ovary and cystic cows had a higher body condition score before calving and lost more condition than normal or persistent CL cows. Immediately postpartum, IGF-I levels were higher and rose sharply in cows that cycled normally than in cystic, inactive ovary or persistent CL cows. At calving and early postpartum, FFA was higher in inactive ovary and cystic than in normal and persistent CL cows. There was a significant strong positive relationship between IGF-I and BUN, and strong negative relationships between IGF-I and FFA and AST in all groups. There was a positive relationship between serum IGF-I and estradiol in normal cystic and inactive ovary cows. This study found that overconditioned cows during the dry period or at calving, lost more body condition postpartum. These cows also had a deeper and longer period of negative energy balance (NEB), poor liver function and low circulating IGF-I concentrations early postpartum. Such cows were likely to have poor reproductive function as seen in development of cystic ovaries, persistent CL and inactive ovary. Changes in serum IGF-I early postpartum may help predict both nutritional and reproductive status in dairy cattle.  (+info)

Desmoglein isotype expression in the hair follicle and its cysts correlates with type of keratinization and degree of differentiation. (5/39)

Within stratified squamous epithelia, such as the epidermis, desmogleins are generally expressed in a differentiation-specific manner. Similar to the epidermis, the hair follicle is compartmentalized into a hierarchy of cell types based on their level of differentiation. Relatively undifferentiated stem cells in the bulge can generate epidermis, sebaceous gland, and hair bulb matrix cells. The latter give rise to at least six different cell types that keratinize as they move up the hair shaft and inner root sheath. Here, we examined expression patterns of the desmoglein isotypes, desmogleins 1, 2, and 3 in the cutaneous epithelium, and discovered that desmoglein 1 and 2 expression correlated with the state of differentiation of defined populations within the hair follicle. Desmoglein 2 was highly expressed by the least differentiated cells of the cutaneous epithelium, including the hair follicle bulge of the fetus and adult, bulb matrix cells, and basal layer of the outer root sheath. In contrast, desmoglein 1 defined more differentiated cell populations, and was expressed in epidermal suprabasal cells, the inner root sheath, and the innermost layers of the outer root sheath. We found that the expression pattern of desmoglein 3 correlated with different types of keratinization. In areas of trichilemmal keratinization in the follicle, and in cysts arising from these areas, desmoglein 3 was expressed throughout all layers of the outer root sheath and cyst wall. In areas of epidermal-like keratinization, such as in the infundibulum and in epidermal inclusion cysts, desmoglein 3 expression was limited mainly to the basal layer. We conclude that desmoglein expression patterns define compartments of cells in similar states of differentiation within the cutaneous epithelium, and reveal a hierarchy of differentiation among these compartments.  (+info)

Adenomatous hyperplasia of the thyroid gland in beluga whales (Delphinapterus leucas) from the St. Lawrence Estuary and Hudson Bay, Quebec, Canada. (6/39)

We evaluated thyroid gland lesions in beluga whales (Delphinapterus leucas) from the St. Lawrence Estuary (n = 16) and Hudson Bay (n = 14). Follicular cysts and nodules of adenomatous hyperplasia of the thyroid gland were found in eight and nine adults from the St. Lawrence Estuary (n = 10), respectively, and in four and six adults from Hudson Bay (n = 14), respectively. The total volume of the lesions of thyroid adenomatous hyperplasia was positively correlated with age in both populations. Comparison between populations could not be performed because of differences in age structures of sample groups. Beluga whales from both populations have unique thyroid lesions among marine mammals.  (+info)

Immunohistochemical localization of 3beta-hydroxysteroid dehydrogenase in the granulosa and theca interna layers of bovine cystic follicles. (7/39)

The aim of the present study was to determine whether the alteration of population of cells containing 3beta-hydroxysteroid dehydrogenase (3beta-HSD) is responsible for the formation of cystic follicles. Paraffin sections of healthy (2 to 5 mm in diameter), atretic (2 to 5 mm) and cystic follicles (more than 25 mm) were immunohistochemically stained with rabbit polyclonal antibody to bovine 3beta-HSD. The 3beta-HSD-positive cells were counted in 4 different regions of the follicles from the apical to the basal side. The frequencies of 3beta-HSD-positive granulosa cells in cystic follicles were significantly higher than those in the healthy follicles (P<0.05), although the number of 3beta-HSD-positive granulosa cells in the cystic follicle were fewer than half the cells (30 to 40%) and was much smaller than that in preovulatory follicles (Conley et al., 1995). The frequencies of 3beta-HSD-positive cells were higher in the granulosa layer and lower in the theca interna layer of the cystic follicles than the atretic follicles. These results suggest that the differentiation of granulosa cells to express 3beta-HSD might be insufficient in cystic follicles and accordingly they fail to ovulate. The differences of frequencies of 3beta-HSD-positive cells in the granulosa and theca interna layers between cystic and atretic follicles may be one of the reasons why regression is delayed in cystic follicles.  (+info)

Studies on the regulation of expression of luteinizing hormone receptor in the ovary and the mechanism of follicular cyst formation in ruminants. (8/39)

In the series of studies, changes of expression and regulation of luteinizing hormone (LH) receptor in the ovary of domestic ruminants were examined. Furthermore, mechanisms of formation of follicular cysts in domestic ruminants, caused by stress and so on, were endocrinologically elucidated. Results of the studies provide the following conclusions. (1) The quantity of LH receptor in the bovine antral follicles increases rapidly in the latter stage of its development. (2) The quantity of LH receptor and its mRNA in the bovine and caprine corpus luteum increase during their developments. The increase of the receptor in the caprine luteal development is regulated by LH through the receptor mRNA level. (3) At least, three splice variants of LH receptor mRNA exist in the bovine luteal tissue and the variant receptors are expressed at different cellular sites according to its structure. (4) Intracellular consecutive cysteine residues of LH receptor are palmitoylated and thereby inhibit internalization of the receptor. (5) As a mechanism of the bovine follicular cyst caused by stress, it is suggested that increased secretions of progesterone and cortisol from the adrenal gland exert inhibitory effects on the hypothalamus and follicle, respectively, and subsequently LH and FSH surges are blocked, then finally ovulation is suppressed and the follicle becomes cystic.  (+info)

A Follicular Cyst is a type of cyst that forms within a follicle, which is the sac-like structure in the skin that contains and protects a hair root. In particular, it refers to a specific condition in the ovary where a follicle fails to rupture or release an egg after maturation, instead continuing to grow and fill with fluid, forming a cyst. These cysts are usually asymptomatic but can become large and cause symptoms such as pelvic pain or discomfort, irregular menstrual cycles, or abnormal vaginal bleeding. In most cases, follicular cysts resolve on their own within 2-3 menstrual cycles, but in rare cases, they may require medical intervention if they become complicated or do not resolve.

An ovarian cyst is a sac or pouch filled with fluid that forms on the ovary. Ovarian cysts are quite common in women during their childbearing years, and they often cause no symptoms. In most cases, ovarian cysts disappear without treatment over a few months. However, larger or persistent cysts may require medical intervention, including surgical removal.

There are various types of ovarian cysts, such as functional cysts (follicular and corpus luteum cysts), which develop during the menstrual cycle due to hormonal changes, and non-functional cysts (dermoid cysts, endometriomas, and cystadenomas), which can form due to different causes.

While many ovarian cysts are benign, some may have malignant potential or indicate an underlying medical condition like polycystic ovary syndrome (PCOS). Regular gynecological check-ups, including pelvic examinations and ultrasounds, can help detect and monitor ovarian cysts.

A cyst is a closed sac, having a distinct membrane and division between the sac and its surrounding tissue, that contains fluid, air, or semisolid material. Cysts can occur in various parts of the body, including the skin, internal organs, and bones. They can be caused by various factors, such as infection, genetic predisposition, or blockage of a duct or gland. Some cysts may cause symptoms, such as pain or discomfort, while others may not cause any symptoms at all. Treatment for cysts depends on the type and location of the cyst, as well as whether it is causing any problems. Some cysts may go away on their own, while others may need to be drained or removed through a surgical procedure.

Odontogenic cysts are a type of cyst that originates from the dental tissues or odontogenic apparatus. They are typically found in the jawbones, and can be classified as developmental or inflammatory in origin. Developmental odontogenic cysts arise from remnants of the tooth-forming structures, while inflammatory odontogenic cysts result from an infection or injury to a tooth.

The most common types of odontogenic cysts include:

1. Periapical cyst - an inflammatory cyst that forms at the tip of the root of a dead or non-vital tooth.
2. Dentigerous cyst - a developmental cyst that surrounds the crown of an unerupted or impacted tooth.
3. Follicular cyst - a type of dentigerous cyst that forms around the crown of an unerupted wisdom tooth.
4. Odontogenic keratocyst - a developmental cyst that arises from the dental lamina and has a high recurrence rate.
5. Lateral periodontal cyst - a rare, developmental cyst that forms in the periodontal ligament of a vital tooth.

Odontogenic cysts can cause various symptoms such as swelling, pain, or numbness in the affected area. They may also displace or resorb adjacent teeth. Diagnosis is typically made through radiographic imaging and histopathological examination of tissue samples obtained through biopsy. Treatment options include surgical excision, marsupialization (a procedure that creates an opening between the cyst and oral cavity), or enucleation (removal of the cyst lining).

Gonadal hormones, also known as sex hormones, are steroid hormones that are primarily produced by the gonads (ovaries in females and testes in males). They play crucial roles in the development and regulation of sexual characteristics and reproductive functions. The three main types of gonadal hormones are:

1. Estrogens - predominantly produced by ovaries, they are essential for female sexual development and reproduction. The most common estrogen is estradiol, which supports the growth and maintenance of secondary sexual characteristics in women, such as breast development and wider hips. Estrogens also play a role in regulating the menstrual cycle and maintaining bone health.

2. Progesterone - primarily produced by ovaries during the menstrual cycle and pregnancy, progesterone prepares the uterus for implantation of a fertilized egg and supports the growth and development of the fetus during pregnancy. It also plays a role in regulating the menstrual cycle.

3. Androgens - produced by both ovaries and testes, but primarily by testes in males. The most common androgen is testosterone, which is essential for male sexual development and reproduction. Testosterone supports the growth and maintenance of secondary sexual characteristics in men, such as facial hair, a deeper voice, and increased muscle mass. It also plays a role in regulating sex drive (libido) and bone health in both males and females.

In summary, gonadal hormones are steroid hormones produced by the gonads that play essential roles in sexual development, reproduction, and maintaining secondary sexual characteristics.

Ameloblastoma is a slow-growing, non-cancerous tumor that develops in the jawbone, typically in the lower jaw. It originates from the cells that form the enamel (the hard, outer surface of the teeth). This tumor can cause swelling, pain, and displacement or loosening of teeth. In some cases, it may also lead to fractures of the jawbone.

There are different types of ameloblastomas, including solid or multicystic, unicystic, and peripheral ameloblastoma. Treatment usually involves surgical removal of the tumor, with careful monitoring to ensure that it does not recur. In rare cases, more aggressive treatment may be necessary if the tumor is large or has invaded surrounding tissues.

It's important to note that while ameloblastomas are generally benign, they can still cause significant morbidity and should be treated promptly by an oral and maxillofacial surgeon or other qualified healthcare professional.

Cattle diseases are a range of health conditions that affect cattle, which include but are not limited to:

1. Bovine Respiratory Disease (BRD): Also known as "shipping fever," BRD is a common respiratory illness in feedlot cattle that can be caused by several viruses and bacteria.
2. Bovine Viral Diarrhea (BVD): A viral disease that can cause a variety of symptoms, including diarrhea, fever, and reproductive issues.
3. Johne's Disease: A chronic wasting disease caused by the bacterium Mycobacterium avium subspecies paratuberculosis. It primarily affects the intestines and can cause severe diarrhea and weight loss.
4. Digital Dermatitis: Also known as "hairy heel warts," this is a highly contagious skin disease that affects the feet of cattle, causing lameness and decreased productivity.
5. Infectious Bovine Keratoconjunctivitis (IBK): Also known as "pinkeye," IBK is a common and contagious eye infection in cattle that can cause blindness if left untreated.
6. Salmonella: A group of bacteria that can cause severe gastrointestinal illness in cattle, including diarrhea, dehydration, and septicemia.
7. Leptospirosis: A bacterial disease that can cause a wide range of symptoms in cattle, including abortion, stillbirths, and kidney damage.
8. Blackleg: A highly fatal bacterial disease that causes rapid death in young cattle. It is caused by Clostridium chauvoei and vaccination is recommended for prevention.
9. Anthrax: A serious infectious disease caused by the bacterium Bacillus anthracis. Cattle can become infected by ingesting spores found in contaminated soil, feed or water.
10. Foot-and-Mouth Disease (FMD): A highly contagious viral disease that affects cloven-hooved animals, including cattle. It is characterized by fever and blisters on the feet, mouth, and teats. FMD is not a threat to human health but can have serious economic consequences for the livestock industry.

It's important to note that many of these diseases can be prevented or controlled through good management practices, such as vaccination, biosecurity measures, and proper nutrition. Regular veterinary care and monitoring are also crucial for early detection and treatment of any potential health issues in your herd.

Ovulation is the medical term for the release of a mature egg from an ovary during a woman's menstrual cycle. The released egg travels through the fallopian tube where it may be fertilized by sperm if sexual intercourse has occurred recently. If the egg is not fertilized, it will break down and leave the body along with the uterine lining during menstruation. Ovulation typically occurs around day 14 of a 28-day menstrual cycle, but the timing can vary widely from woman to woman and even from cycle to cycle in the same woman.

During ovulation, there are several physical changes that may occur in a woman's body, such as an increase in basal body temperature, changes in cervical mucus, and mild cramping or discomfort on one side of the lower abdomen (known as mittelschmerz). These symptoms can be used to help predict ovulation and improve the chances of conception.

It's worth noting that some medical conditions, such as polycystic ovary syndrome (PCOS) or premature ovarian failure, may affect ovulation and make it difficult for a woman to become pregnant. In these cases, medical intervention may be necessary to help promote ovulation and increase the chances of conception.

Cyst fluid refers to the fluid accumulated within a cyst, which is a closed sac-like or capsular structure, typically filled with liquid or semi-solid material. Cysts can develop in various parts of the body for different reasons, and the composition of cyst fluid may vary depending on the type of cyst and its location.

In some cases, cyst fluid might contain proteins, sugars, hormones, or even cells from the surrounding tissue. Infected cysts may have pus-like fluid, while cancerous or precancerous cysts might contain abnormal cells or tumor markers. The analysis of cyst fluid can help medical professionals diagnose and manage various medical conditions, including infections, inflammatory diseases, genetic disorders, and cancers.

It is important to note that the term 'cyst fluid' generally refers to the liquid content within a cyst, but the specific composition and appearance of this fluid may vary significantly depending on the underlying cause and type of cyst.

An ovarian follicle is a fluid-filled sac in the ovary that contains an immature egg or ovum (oocyte). It's a part of the female reproductive system and plays a crucial role in the process of ovulation.

Ovarian follicles start developing in the ovaries during fetal development, but only a small number of them will mature and release an egg during a woman's reproductive years. The maturation process is stimulated by hormones like follicle-stimulating hormone (FSH) and luteinizing hormone (LH).

There are different types of ovarian follicles, including primordial, primary, secondary, and tertiary or Graafian follicles. The Graafian follicle is the mature follicle that ruptures during ovulation to release the egg into the fallopian tube, where it may be fertilized by sperm.

It's important to note that abnormal growth or development of ovarian follicles can lead to conditions like polycystic ovary syndrome (PCOS) and ovarian cancer.

Progesterone is a steroid hormone that is primarily produced in the ovaries during the menstrual cycle and in pregnancy. It plays an essential role in preparing the uterus for implantation of a fertilized egg and maintaining the early stages of pregnancy. Progesterone works to thicken the lining of the uterus, creating a nurturing environment for the developing embryo.

During the menstrual cycle, progesterone is produced by the corpus luteum, a temporary structure formed in the ovary after an egg has been released from a follicle during ovulation. If pregnancy does not occur, the levels of progesterone will decrease, leading to the shedding of the uterine lining and menstruation.

In addition to its reproductive functions, progesterone also has various other effects on the body, such as helping to regulate the immune system, supporting bone health, and potentially influencing mood and cognition. Progesterone can be administered medically in the form of oral pills, intramuscular injections, or vaginal suppositories for various purposes, including hormone replacement therapy, contraception, and managing certain gynecological conditions.

Follicle-Stimulating Hormone (FSH) is a glycoprotein hormone secreted and released by the anterior pituitary gland. In females, it promotes the growth and development of ovarian follicles in the ovary, which ultimately leads to the maturation and release of an egg (ovulation). In males, FSH stimulates the testes to produce sperm. It works in conjunction with luteinizing hormone (LH) to regulate reproductive processes. The secretion of FSH is controlled by the hypothalamic-pituitary-gonadal axis and its release is influenced by the levels of gonadotropin-releasing hormone (GnRH), estrogen, inhibin, and androgens.

Luteinizing Hormone (LH) is a glycoprotein hormone, which is primarily produced and released by the anterior pituitary gland. In women, a surge of LH triggers ovulation, the release of an egg from the ovaries during the menstrual cycle. During pregnancy, LH stimulates the corpus luteum to produce progesterone. In men, LH stimulates the testes to produce testosterone. It plays a crucial role in sexual development, reproduction, and maintaining the reproductive system.

Estradiol is a type of estrogen, which is a female sex hormone. It is the most potent and dominant form of estrogen in humans. Estradiol plays a crucial role in the development and maintenance of secondary sexual characteristics in women, such as breast development and regulation of the menstrual cycle. It also helps maintain bone density, protect the lining of the uterus, and is involved in cognition and mood regulation.

Estradiol is produced primarily by the ovaries, but it can also be synthesized in smaller amounts by the adrenal glands and fat cells. In men, estradiol is produced from testosterone through a process called aromatization. Abnormal levels of estradiol can contribute to various health issues, such as hormonal imbalances, infertility, osteoporosis, and certain types of cancer.

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.

"Cattle" is a term used in the agricultural and veterinary fields to refer to domesticated animals of the genus *Bos*, primarily *Bos taurus* (European cattle) and *Bos indicus* (Zebu). These animals are often raised for meat, milk, leather, and labor. They are also known as bovines or cows (for females), bulls (intact males), and steers/bullocks (castrated males). However, in a strict medical definition, "cattle" does not apply to humans or other animals.

The follicular phase is a term used in reproductive endocrinology, which refers to the first part of the menstrual cycle. This phase begins on the first day of menstruation and lasts until ovulation. During this phase, several follicles in the ovaries begin to mature under the influence of follicle-stimulating hormone (FSH) released by the pituitary gland.

Typically, one follicle becomes dominant and continues to mature, while the others regress. The dominant follicle produces increasing amounts of estrogen, which causes the lining of the uterus to thicken in preparation for a possible pregnancy. The follicular phase can vary in length, but on average it lasts about 14 days.

It's important to note that the length and characteristics of the follicular phase can provide valuable information in diagnosing various reproductive disorders, such as polycystic ovary syndrome (PCOS) or thyroid dysfunction.

Follicular fluid is the fluid that accumulates within the follicle (a small sac or cyst) in the ovary where an egg matures. This fluid contains various chemicals, hormones, and proteins that support the growth and development of the egg cell. It also contains metabolic waste products and other substances from the granulosa cells (the cells that surround the egg cell within the follicle). Follicular fluid is often analyzed in fertility treatments and studies as it can provide valuable information about the health and viability of the egg cell.

An epidermal cyst is a common benign skin condition characterized by the growth of a sac-like structure filled with keratin, a protein found in the outermost layer of the skin (epidermis). These cysts typically appear as round, firm bumps just under the surface of the skin, often on the face, neck, trunk, or scalp. They can vary in size from a few millimeters to several centimeters in diameter.

Epidermal cysts usually develop as a result of the accumulation of dead skin cells that become trapped within a hair follicle or a pilosebaceous unit (a structure that contains a hair follicle and an oil gland). The keratin produced by the skin cells then collects inside the sac, causing it to expand gradually.

These cysts are generally slow-growing, painless, and rarely cause any symptoms. However, they may become infected or inflamed, leading to redness, tenderness, pain, or pus formation. In such cases, medical attention might be necessary to drain the cyst or administer antibiotics to treat the infection.

Epidermal cysts can be removed surgically if they cause cosmetic concerns or become frequently infected. The procedure typically involves making an incision in the skin and removing the entire sac along with its contents to prevent recurrence.

Inhibins are a group of protein hormones that play a crucial role in regulating the function of the reproductive system, specifically by inhibiting the production of follicle-stimulating hormone (FSH) in the pituitary gland. They are produced and secreted primarily by the granulosa cells in the ovaries of females and Sertoli cells in the testes of males.

Inhibins consist of two subunits, an alpha subunit, and a beta subunit, which can be further divided into two types: inhibin A and inhibin B. Inhibin A is primarily produced by the granulosa cells of developing follicles in the ovary, while inhibin B is mainly produced by the Sertoli cells in the testes.

By regulating FSH production, inhibins help control the development and maturation of ovarian follicles in females and spermatogenesis in males. Abnormal levels of inhibins have been associated with various reproductive disorders, including polycystic ovary syndrome (PCOS) and certain types of cancer.
