A hormone produced mainly by growing follicles in females and Sertoli cells in males, it downregulates the biosynthesis and production of follicular stimulating hormone (FSH). Inhibin B is composed of alpha and beta B dimer subunits. It is also used as a marker for male infertility and spermatogenesis.
