gonadotropic hormone (gō'nădətrŏp'ĭk) or gonadotropin, any one of three glycoprotein (see protein) hormones released by either the anterior pituitary gland or the placenta (the organ in which maternal and fetal blood exchange nutrients and waste products) that have various effects upon the ovaries and testes (see testis).

Gonadotropin
Gonadotropins are protein hormones secreted by gonadotrope cells of the pituitary gland of vertebrates. The two principal gonadotropins are luteinizing hormone (LH) and follicle stimulating hormone (FSH). Both hormones consist of two peptide chains, an alpha chain and a beta chain, linked by disulfide bonds. LH and FSH share nearly identical alpha chains, while the beta chain provides specificity for receptor interactions

Gonadal Peptides: Activin/Inhibin (Act/Inh)
Bremner (1989) stated that inhibin, a gonadal glycoprotein hormone which regulates pituitary FSH (136530) secretion, was postulated to exist in the 1920s and named in 1932, but 'during the next 40 years...attained only slightly more scientific credibility than the unicorn.' Inhibin exists in 2 forms, each of which shares the same alpha subunit and, when covalently linked to 1 of 2 distinct subunits called beta-a and beta-b, strongly inhibits pituitary FSH secretion. On the other hand, the dimers of 2 beta subunits, termed activin, are potent stimulators of FSH secretion and release in vitro. Both Inhibin and Activin are members of the Transforming Growth Factor Beta (TGFB) superfamily

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 Anti-Müllerian hormone (AMH)) activin belongs to the 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.
