WebAmong these factors, members of the transforming growth factor-β (TGFβ ) superfamily such as activin, inhibin and bone morphogenetic protein-2 (BMP2) and 4 (BMP4), have the ability to increase FSH release and Fshb expression, and are thus believed to contribute to the differential regulation of gonadotropins6–8. WebStructurally similar to the hormone activin, but functionally opposite to the hormone, inhibin is the hormone that suppresses the secretion of the hormone FSH. It is usually secreted by the granulosa cell of the ovary and Sertoli cells of the testes but sometimes also secreted by the other tissues like the pituitary and the placenta.
