Estradiol is a powerful inhibitor of FSH (follicle stimulating hormone). What is another factor that is a powerful inhibitor of FSH in the female?
Testosterone
Progesterone
LH
Inhibin
Inhibin, as its name implies, is an inhibitor. The specific action of inhibin is to inhibit the release of FSH. Inhibin occurs as a heterodimer It is produced in the male and the female. Inhibin is produced by the ovarian granulosa cells to prevent more than one follicle (in general) from becoming a mature follicle. The inhibin produced by the Seoli cells of the testes acts to decrease FSH to help in regulation of spermatogenesis. Ref: Molina P.E. (2013). Chapter 8. Male Reproductive System. In P.E.
