Follicle stimulating hormone (FSH) is a hormone synthesized and secreted by gonadotropes in the anterior pituitary gland. FSH and LH act synergistically in reproduction. In the ovary, FSH stimulates the growth of immature Graafian follicles to maturation. As the follicle grows it releases inhibin, which shuts off the FSH production. In men, FSH enhances the production of androgen-binding protein by the Sertoli cells of the testes and is critical for spermatogenesis. In both males and females, FSH stimulates the maturation of germ cells. In females, FSH initiates follicular growth, specifically affecting granulosa cells.
Follicle stimulating hormone (FSH) Human is a glycoprotein produced from urine of post-menopausal women and having a total molecular mass of 30 kDa. FSH is a heterodimeric hormone consisting of 92 amino acids (ë± chain) and 111 amino acids (ë_ chain). FSH was lyophilized with no additives and purified by proprietary chromatographic techniques.
