two corpora cavernosa corpus spongiosum

Question 50

describe how male hormones are produces

Answer 50

GnRH (gonadotropin-releasing hormone ) secreted by hypothalamus triggers release of FSH and LH from anterior pituitary. FSH targets nurse cells to trigger spermatogenesis. LH causes interstitial cells to secrete testosterone
