TestosteroneIII. Reproductive EndocrinologyCurrent LectureI. Reproductive system a. Maintained by reproductive hormonesb. Hypothalamus- releases gnRH to anterior pituitary to release its own hormonesc. Hypothalamus stimulates pituitary to secrete LH and FSHi. Luteinizing hormone and follicule stimulating hormoneii. LH stimulates interstitial cells to secrete testosteroneiii. FSH stimulates Sertoli cells to secrete androgen-binding protein. iv. These travel throughout the body, and most cells ignore these hormones because they do not have receptors for the hormonesv. Testis are target for LH and FSHII. Testosteronea. Maintains primary and secondary sexual characteristics in meni. Primary-testis, penis, ducts that carry spermii. Secondary-deep voice, body hair, facial hair, increased muscle massb. Also stimulates spermatogenesis by binding to spermategoniumIII. Reproductive endocrinology (Females)a. Hypothalamus, anterior pituitary, gnRH, LH, FSH are all includedi. Egg cells surrounded by a bunch of other cells called follicle cellsii. Oocyte + follicle cells is called the follicle. iii. Primary oocytes are stopped in prophase IThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.iv. Women of reproductive age release gnRH, LH, FSH, and FSH stimulates follicle tostart going through meiosisIV. Exam ends with male reproductive
