1 Introduction
Activin

Wikipedia

 

Activin is a peptide that enhances FSH synthesis and secretion and participates in the regulation of the menstrual cycle. It does the opposite as inhibin.





Activin contains two beta subunit that are identical to the two beta subunits (A or B) of inhibin, allowing for the formation of three forms of activin: A, AB, and B.
Like inhibin (and AMH) activin belongs to the transforming growth factor|transforming growth factor-β (TGF-β) family.





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 produced in the gonads, pituitary gland, placenta and other organs.
