Ovarian follicle: Ovarian follicle is a roughly spheroid cellular aggregation set found in the ovaries. It also secretes hormones that influence stages of the menstrual cycle.Hair follicle nevus: Hair follicle nevus (also known as a "Vellus hamartoma") is a cutaneous condition that presents as a small papule from which fine hairs protrude evenly from the surface.Theca: A theca (plural thecae) refers to a sheath or a covering.Estradiol cypionate: Estradiol cypionate (INN, USAN) (brand names Depo-Estradiol, Depofemin, Estradep, and many others), or estradiol cipionate, is a synthetic ester, specifically the 3-cyclopentylpropanoyl ester, of the natural estrogen, estradiol. It was first introduced in 1952 by Upjohn in the United States, and has been in widespread use since.Oocyte selection: Oocyte selection is a procedure that is performed prior to in vitro fertilization, in order to use oocytes with maximal chances of resulting in pregnancy. In contrast, embryo selection takes place after fertilization.Vitellogenesis: Vitellogenesis (also known as yolk deposition) is the process of yolk formation via nutrients being deposited in the oocyte, or female germ cell involved in reproduction. In insects, it starts when the fat body stimulates the release of juvenile hormones and produces vitellogenin protein.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.AndrostenedioneSKI protein: The Ski protein is a nuclear protooncoprotein that is associated with tumors at high cellular concentrations. Ski has been shown to interfere with normal cellular functioning by both directly impeding expression of certain genes inside the nucleus of the cell as well as disrupting signaling proteins that activate genes.Beef cattle: Beef cattle are cattle raised for meat production (as distinguished from dairy cattle, used for milk production). The meat of adult cattle is known as beef.Aromatase deficiency: Aromatase deficiency is a condition resulting from insufficient production of the enzyme aromatase, which can lead to inappropriate virilization in females.Corpus luteum cystTheca lutein cyst: A Theca lutein cyst is a type of bilateral functional ovarian cyst filled with clear, straw-colored fluid. To be classified a functional cyst, the mass must reach a diameter of at least three centimeters.Gs alpha subunit: The Gs alpha subunit (Gαs, Gsα, or Gs protein) is a heterotrimeric G protein subunit that activates the cAMP-dependent pathway by activating adenylyl cyclase. A mnemonic for remembering this subunit is to look at the first letters in each word (Gαs = Adenylate Syclase).CyclohexeneEstrous cycle: The estrous cycle (also oestrous cycle; derived from Latin oestrus and originally from Greek οἶστρος meaning sexual desire) comprises the recurring physiologic changes that are induced by reproductive hormones in most mammalian therian females. Estrous cycles start after sexual maturity in females and are interrupted by anestrous phases or pregnancies.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.GDF6: Growth differentiation factor 6 (GDF6) is a protein that in humans is encoded by the GDF6 gene.DivinylbenzenePrimary ovarian insufficiency: Primary Ovarian Insufficiency (POI), formerly known as premature ovarian failure, is defined as the cessation of normal ovarian function before age 40 years. It is the scientifically accurate term for the condition that was previously referred to as premature menopause or premature ovarian failure.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.Corriedale: Corriedale sheep are a dual purpose breed, meaning they are used both in the production of wool and meat. The Corriedale is the oldest of all the crossbred breeds, a Merino-Lincoln cross developed almost simultaneously in Australia and New ZealandStock Types, The Land, North Richmond, c.Cholesterol side-chain cleavage enzyme: Cholesterol side-chain cleavage enzyme is commonly referred to as P450scc, where "scc" is an acronym for side-chain cleavage. P450scc is a mitochondrial enzyme that catalyzes conversion of cholesterol to pregnenolone.Hair analysisAnovulationMature messenger RNA: Mature messenger RNA, often abbreviated as mature mRNA is a eukaryotic RNA transcript that has been spliced and processed and is ready for translation in the course of protein synthesis. Unlike the eukaryotic RNA immediately after transcription known as precursor messenger RNA, it consists exclusively of exons, with all introns removed.Natural cycle in vitro fertilization: Natural Cycle IVF is in vitro fertilisation (IVF) using either of the following procedures: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.Subtherapeutic antibiotic use in swine: Antibiotics are commonly used in commercial swine production in the United States and around the world. They are used for disease treatment, disease prevention and control, and growth promotion.Prenatal testosterone transfer: Prenatal Testosterone Transfer (also known as prenatal androgen transfer or prenatal hormone transfer) refers to the phenomenon in which testosterone synthesized by a developing male fetus transfers to one or more developing fetuses within the womb and influences development. This typically results in the partial masculinization of specific aspects of female behavior, cognition, and morphology, though some studies have found that testosterone transfer can cause an exaggerated masculinization in males.Sarah R, Lotfi: Sarah R. Lotfi (b.Gonadotropin-releasing hormone analogue: A gonadotropin-releasing hormone analogue (GnRH analogue or analog), also known as a luteinizing hormone releasing hormone agonist (LHRH agonist) or LHRH analogue is a synthetic peptide drug modeled after the human hypothalamic gonadotropin-releasing hormone (GnRH). A GnRH analogue is designed to interact with the GnRH receptor and modify the release of pituitary gonadotropins FSH and LH for therapeutic purposes.Ovarian diseaseSteroid use in Bollywood: The use of steroids by Bollywood actors has become highlighted in a number of newspaper and web articles where actors and models with previously very thin physiques have in a short period of time developed muscular bodies.BuserelinCumulus oophorus: The cumulus oophorus (Latin cumulus=heap, Greek oo=egg + phor=carrier; Latinized ending "-us"), also called discus proligerus, is a cluster of cells (called cumulus cells) that surround the oocyte both in the ovarian follicle and after ovulation. In the antral follicle, it may be regarded as an extension of the membrana granulosa.Chicken as biological research model: Chickens (Gallus gallus domesticus) and their eggs have been used extensively as research models throughout the history of biology. Today they continue to serve as an important model for normal human biology as well as pathological disease processes.Immobilized enzyme: An immobilized enzyme is an enzyme that is attached to an inert, insoluble material such as calcium alginate (produced by reacting a mixture of sodium alginate solution and enzyme solution with calcium chloride). This can provide increased resistance to changes in conditions such as pH or temperature.Activin and inhibin: Activin and inhibin are two closely related protein complexes that have almost directly opposite biological effects. Identified in 1986, activin enhances FSH biosynthesis and secretion, and participates in the regulation of the menstrual cycle.Controlled internal drug release: Controlled internal drug release (CIDR) devices are used in livestock for the synchronization of estrus. They are T-shaped devices with a silicone-coated nylon core.HypophysectomyOvarian tissue cryopreservation: Ovarian tissue cryopreservation is cryopreservation of tissue of the ovary of a female.Insulin-like growth factor 2: Insulin-like growth factor 2 (IGF-2) is one of three protein hormones that share structural similarity to insulin. The MeSH definition reads: "A well-characterized neutral peptide believed to be secreted by the liver and to circulate in the blood.Eggshell: An eggshell is the outer covering of a hard-shelled egg and of some forms of eggs with soft outer coats. Bird eggshells contain calcium carbonate and dissolve in various acids, including the vinegar used in cooking.Temporal analysis of products: Temporal Analysis of Products (TAP), (TAP-2), (TAP-3) is an experimental technique for studying
