Cumulus 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.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.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.Natural cycle in vitro fertilization: Natural Cycle IVF is in vitro fertilisation (IVF) using either of the following procedures:GDF6: Growth differentiation factor 6 (GDF6) is a protein that in humans is encoded by the GDF6 gene.Postcoital test: The postcoital test (PCT) (also known as Sims test, Huhner test or Sims-Huhner test) is a test in the evaluation of infertility. The test examines interaction between sperm and mucus of the cervix.Immunosurgery: Immunosurgery is a method of removing an external cell layer of an object. Immunosurgery is to expose the specimen to a solution containing antibodies against the object, remove that solution and subsequently expose the object to complement.Hyaluronidase: The hyaluronidases () are a family of enzymes that degrade hyaluronic acid. Karl Meyer classified these enzymes in 1971 into three distinct groups, a scheme based on the enzyme reaction products.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.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.Gastrocopta pellucida: Gastrocopta pellucida is a species of minute air-breathing land snail, a terrestrial pulmonate gastropod mollusk or micromollusk in the family Vertiginidae, the vertigo snails.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.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.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.Spermiogenesis: Spermiogenesis is the final stage of spermatogenesis, which sees the maturation of spermatids into mature, motile spermatozoa. The spermatid is more or less circular cell containing a nucleus, Golgi apparatus, centriole and mitochondria.Hyaluronan synthase: Hyaluronan synthases (HAS) are membrane-bound enzymes which use UDP-α-N-acetyl-D-glucosamine and UDP-α-D-glucuronate as substrates to produce the glycosaminoglycan hyaluronan at the cell surface and extrude it through the membrane into the extracellular space.Cryoprotectant: A cryoprotectant is a substance used to protect biological tissue from freezing damage (i.e.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).Midkine: Midkine (MK or MDK) also known as neurite growth-promoting factor 2 (NEGF2) is a protein that in humans is encoded by the MDK gene.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.Buffalo burger: Buffalo burgers are hamburgers made with meat from the American bison (Bison bison), or water buffalo (Bubalus bubalis) in the United Kingdom.Gap junction: A gap junction may also be called a nexus or macula communicans. When found in nerves they are also referred to as an electrical synapse.Telescoping generations: Telescoping generations can occur in parthenogenetic species, such as aphids or other life forms that have the ability to reproduce without ovum fertilization. This occurrence is characterized by a viviparous female having a daughter growing inside her that is also parthenogenetically pregnant with a daughter cell.Eagle's minimal essential medium: Eagle's minimal essential medium (EMEM) is a cell culture medium developed by Harry Eagle that can be used to maintain cells in tissue culture.Ovarian tissue cryopreservation: Ovarian tissue cryopreservation is cryopreservation of tissue of the ovary of a female.Sarah R, Lotfi: Sarah R. Lotfi (b.Xueren: Xueren (English: The ScholarThe Scholar was the translation preferred by the editors of Xueren, appearing thus in their journal, but the title is sometimes also translated Scholars.) was an influential Chinese independent intellectual journal that ran from 1991 to 2000.Heparin-binding EGF-like growth factor: Heparin-binding EGF-like growth factor (HB-EGF) is a member of the EGF family of proteins that in humans is encoded by the HBEGF gene.Maternal to zygotic transition: Maternal to zygotic transition (MZT) is the stage in embryonic development during which development comes under the exclusive control of the zygotic genome. This requires both zygotic genome activation (ZGA) and degradation of maternal products.Mature 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.Metaphase: Metaphase (from the Greek μετά, "adjacent" and φάσις, "stage") is a stage of mitosis in the eukaryotic cell cycle in which chromosomes are at their second-most condensed and coiled stage (they are at their most condensed in anaphase. These chromosomes, carrying genetic information, align in the equator of the cell before being separated into each of the two daughter cells.Ethylene glycol poisoningEstradiol 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.Fallopian tube obstructionVitrificationTetraphenyl butadieneSoyasapogenol glucuronosyltransferase: Soyasapogenol glucuronosyltransferase (, UGASGT) is an enzyme with system name UDP-D-glucuronate:soyasapogenol 3-O-D-glucuronosyltransferase. This enzyme catalyses the following chemical reactionPregnancy 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.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.Canadian Thoroughbred Horse Society: The Canadian Thoroughbred Horse Society (CTHS) is an organization headquartered in Toronto, Canada that was founded in 1906 to assist Thoroughbred horse breeders. Since 1982, there have been provincial divisions in Alberta, British Columbia, Manitoba, Ontario, Quebec and Saskatchewan.SKI 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.Sodium pyruvateCystineTemporal analysis of products: Temporal Analysis of Products (TAP), (TAP-2), (TAP-3) is an experimental technique for studyingHyperactivation: Hyperactivation is a type of sperm motility. Hyperactivated sperm motility is characterised by a high amplitude, asymmetrical beating pattern of the sperm tail (flagellum).Inter-alpha-trypsin inhibitor: Inter-alpha-trypsin inhibitors (IαI) are plasma proteins consisting of three of four heavy chains selected from the group ITIH1, ITIH2, ITIH3, ITIH4 and one light chain selected from the group AMBP or SPINT2.
