Epididymis: The epididymis (; plural: epididymides or ) is a tube that connects a testicle to a vas deferens in the male reproductive system. It is present in all male reptiles, birds, and mammals.Blood–testis barrier: The blood–testis barrier is a physical barrier between the blood vessels and the seminiferous tubules of the animal testes. The name "blood-testis barrier" is misleading in that it is not a blood-organ barrier in a strict sense, but is formed between Sertoli cells of the seminiferous tubule and as such isolates the further developed stages of germ cells from the blood.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.Rete tubular ectasia: Rete tubular ectasia is a benign condition, usually found in older men, involving numerous small, tubular cystic structures within the rete testis.TESP (company): TESP (English: Society for the Exploitation of Potassium Salt, Polish: Towarzystwo Eksploatacji Soli Potasowych) was a private mining enterprise, which existed in the Second Polish Republic, with head office in Lwow. It operated potassium salt mines in Kalusz and Stebnik, and sponsored a soccer team TESP Kalusz.EpididymitisEjaculatory duct obstructionArtery to the ductus deferens: The artery to the ductus deferens (deferential artery) is an artery in males that provides blood to the ductus deferens.Vasectomy: Table 26–1 = Table 3–2 Percentage of women experiencing an unintended pregnancy during the first year of typical use and the first year of perfect use of contraception, and the percentage continuing use at the end of the first year. United States.Hyperactivation: Hyperactivation is a type of sperm motility. Hyperactivated sperm motility is characterised by a high amplitude, asymmetrical beating pattern of the sperm tail (flagellum).Sperm: Sperm is the male reproductive cell and is derived from the Greek word (σπέρμα) sperma (meaning "seed"). In the types of sexual reproduction known as anisogamy and its subtype oogamy, there is a marked difference in the size of the gametes with the smaller one being termed the "male" or sperm cell.Seminiferous tubule: Seminiferous tubules are located within the testes, and are the specific location of meiosis, and the subsequent creation of male gametes, namely spermatozoa.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.Excess ovarian androgen release syndrome: Excess ovarian androgen release syndrome (also known as "Ovarian SAHA syndrome")is a cutaneous condition usually seen in young women between the ages of 16 and 20.Hydraulic fracturing proppants: A proppant is a solid material, typically sand, treated sand or man-made ceramic materials, designed to keep an induced hydraulic fracture open, during or following a fracturing treatment. It is added to a frac'ing fluid which may vary in composition depending on the type of fracturing used, and can be gel, foam or slickwater–based.Orchialgia: Orchialgia is long-term pain of the testes. It is considered chronic if it has persisted for more than 3 months.OrchitisMale infertilitySemen quality: Semen quality is a measure of the ability of semen to accomplish fertilization. Thus, it is a measure of fertility in a man.CAP protein family: In molecular biology, the CAP protein family (cysteine-rich secretory proteins, antigen 5, and pathogenesis-related 1 proteins (CAP)) is a large family of proteins that are found in a wide range of organisms, including prokaryotes and non-vertebrate eukaryotes. The nine subfamilies of the mammalian CAP 'super'family include: the human glioma pathogenesis-related 1 (GLIPR1), Golgi associated pathogenesis related-1 (GAPR1) proteins, peptidase inhibitor 15 (PI15), peptidase inhibitor 16 (PI16), cysteine-rich secretory proteins (CRISPs), CRISP LCCL domain containing 1 (CRISPLD1), CRISP LCCL domain containing 2 (CRISPLD2), mannose receptor like and the R3H domain containing like proteins.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.Sertoli cell nodule: A Sertoli cell nodule, also Pick's adenoma, testicular tubular adenoma and tubular adenoma of the testis, is a benign proliferation of Sertoli cells that arises in association with cryptorchidism (undescended testis). They are not composed of a clonal cell population, i.Open-pool Australian lightwater reactor: The Open-pool Australian lightwater reactor (OPAL) is a 20 megawatt (MW) pool-type nuclear research reactor. Officially opened in April 2007, it replaced the High Flux Australian Reactor as Australia's only nuclear reactor, and is located at the Australian Nuclear Science and Technology Organisation (ANSTO) Research Establishment in Lucas Heights, New South Wales, a suburb of Sydney.VasovasostomyMale contraceptive: Male contraceptives are methods of preventing pregnancy that primarily involve the male physiology. The most common kinds of male contraception include condoms, withdrawal / pulling out, outercourse,http://www.You Yangs: The You Yangs are a series of granite ridges that rise to 364m (Flinders Peak) above the Werribee Plain approximately 55 km south-west of Melbourne and 22 km north-east of Geelong, in Victoria, Australia. The main ridge runs roughly north–south for about 9 km, with a lower extension running for about 15 km to the west.Retrograde ejaculationHook protein: HOOK is a family of evolutionarily related proteins.Pampiniform venous plexus: The pampiniform plexus is a network of many small veins found in the human male spermatic cord. It is formed by the union of multiple spermatic veins from the back of the testis and tributaries from the epididymis.Prostate saturation biopsy: Prostate saturation biopsy typically entails 40-80 core samples taken from the prostate under general anesthesia.Centers for Medicare and Medicaid Services]: Summary of Fee Schedule Policies, 2009]Spermatid: The spermatid is the haploid male gametid that results from division of secondary spermatocytes. As a result of meiosis, each spermatid contains only half of the genetic material present in the original primary spermatocyte.Plasmodium osmaniae: Plasmodium osmaniae is a parasite of the genus Plasmodium subgenus Vinckeia.Male genital diseaseStratified squamous epithelium: A stratified squamous epithelium consists of squamous (flattened) epithelial cells arranged in layers upon a basal membrane. Only one layer is in contact with the basement membrane; the other layers adhere to one another to maintain structural integrity.CryptorchidismSpermatoceleScrotal ligament: The scrotal ligament is actually the remnant of gubernaculum in a fetus. This ligament secures the testis to the most inferior portion of the scrotum, tethering it in place and limiting the degree to which the testis can move within the scrotum.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.Leydig cell: Leydig cells, also known as interstitial cells of Leydig, are found adjacent to the seminiferous tubules in the testicle. They produce testosterone in the presence of luteinizing hormone (LH).
