vocabulary #9

Turner’s syndrome a genetic condition in which the female is born with only one X chromosome.   
Anti-mullerian hormone a hormone produced by ovrian and testicular cells that inhibits the development of mullerian ducts in the male embryo.
Hermaphrodite an organism having both male and female sexual organs.
Aromatase an enzyme found in the brain and body that converts testosterone to estradiol.
Wolffian duct embryonic ducts that form the vas deferens in males and ureters in both sexes.
Sertoli cells are found in testicles and are stimulated by the follicle-stimulating hormone to produce sperms (a process known as spermatogenesis).
Mullerian duct embryonic ducts that form the fallopian tubes, uterus, and parts of the vagina. They disintegrate in presence of the anti-mullerian hormone.  
Androgen insensitivity syndrome a condition whereby a genetically male individual cannot respond to androgens in blood. 
Leydig cells  also known as interstitial cells that are found in testicles and produce testosterone in presence of the lutenizing hormone.
SRY gene is a gene on the Y chromosome that codes for the "sex-determining region Y" protein. 
Inhibin a glycoprotein secreted by granulosa (female) and Sertoli (male) cells in response to FSH. Its primary action is the negative feedback control of pituitary FSH synthesis and secretion.
Klinefelters syndrome a genetic condition in which the male is born with an extra copy of the X chromosome.  
Primordial germ cells the common origins of spermatozoa and oocytes.
Dihydrotestosterone (DHT) an androgen sex steroid produced from the conversion of testosterone in presence of the 5α-reductase enzyme. 
Kisspeptin a protein coded by the KISS1 gene that is important in initiating the secretion of gonadotropin-releasing hormone in puberty.
Activin A protein complex, related to inhibin, that enhances FSH biosynthesis and secretion. 
Androgen-binding protein is a glycoprotein produced by the Sertoli cells in the seminiferous tubules of the testis that binds specifically to testosterone (T), dihydrotestosterone (DHT), and 17-beta-estradiol.
Dehydroepiandrosterone (DHEA) A weak androgen precurser to testosterone or estrogen.
Menarche The onset of the first menstrual cycle in females.
