Inhibin testes
Webb26 juli 2024 · In most of the species, inhibin B is the major form of inhibin produced by the Sertoli cells of testes, while spermatogonial cells also express inhibin B (Anderson et al. 1998). Inhibin can be a useful clinical marker for testicular function as inhibin levels show positive correlation with Sertoli cell number, sperm concentration and spermatogonial … 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.
