Folliculos stimulans hormon

Folliculos stimulans hormon, abbreviatura FSH, est hormon ex duabus catenis, alpha (FSHA, OMIM: 118850) et beta (FSHB, OMIM: 136530), compositum. FSH de cellula gonadotropica lobi anterioris hypophysis secernitur. Et in viribus et in muliebris hormono FSH munera propria sunt.

Secretio recensere

Secretio hormontis folliculos stimulantis praecipue ab hypothalamo per decapeptidum hormon liberationis gonadotropinorum (GnRH) moderatur; secretio ipsa ab cellulas gonadotropicas, quae in lobo anteriori hypophysis sitae sunt, fit^[1]. Intra hypophysi, complexus proteinorum et activini (biosynthesis FSH ↑) et inhibini (biosynthesis FSH ↓), velut follistatinum in edita moderandis agunt^[2]. Activinum genum promotorem Fshb subunitatis beta lectum incitat. Subunitas alpha, ut LH, genum alphaGSU requirit.
