Do leydig cells produce inhibin
Activin is produced in the gonads, pituitary gland, placenta, and other organs: • In the ovarian follicle, activin increases FSH binding and FSH-induced aromatization. It participates in androgen synthesis enhancing LH action in the ovary and testis. In the male, activin enhances spermatogenesis. • Activin is strongly expressed in wounded skin, and overexpression of activin in epidermis of transgenic mice improves wound healing and enhances Activin is produced in the gonads, pituitary gland, placenta, and other organs: • In the ovarian follicle, activin increases FSH binding and FSH-induced aromatization.
