Pharmacology
Chogonadotropin is a gonadotropin secreted by placental trophoblast cells. It is similar to luteinizing hormone (
) but has little effect like follicle-stimulating hormone (
). For females, it can promote the maturation and ovulation of follicles and transform the ruptured follicles into the corpus luteum, prompting them to secrete progesterone. For males, it has the effect of stimulating interstitial cells (
), which can promote the function of seminiferous tubules, especially the activity of Leydig cells in the testicles, causing them to produce androgens, promote the development and maturation of sexual organs and accessory sexual characteristics, and promote testicular descent and Promote sperm production.
