Inhibin ovary
WebbAmong the local ovarian factors, there is growing evidence from genetic and experimental data that many members of the transforming growth factor (TGF[beta]) superfamily have a biological role to play in folliculogenesis. These members include activin, inhibin, TGF[beta], BMP, GDF9 and perhaps MIS. WebbThe primary function of the hormone inhibin is the inhibition of the secretion of the FSH by the pituitary. However, the FSH acts on the production of the granulosa cells itself, the coordination between the inhibin and the FSH acts moreover like a negative feedback mechanism. The inhibins are produced by the ovaries as well as pituitary glands ...
