| Question | Answer |
|---|---|
| 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. |
