Sommario
L’ormone luteinizzante (LH) e la gonadotropina corionica umana (hCG) sono glicoproteine che svolgono un ruolo fondamentale per la riproduzione. L’LH modula la sintesi di androgeni e la gametogenesi in entrambi i sessi, mentre l’hCG è prodotta nella donna durante la gravidanza. Questi due ormoni hanno un’origine ancestrale comune, seppure nel corso dell’evoluzione abbiano assunto specifiche funzioni fisiologiche, supportate dall’attivazione di differenti segnali intracellulari mediati da un unico recettore (LHCGR) espresso nelle gonadi. Ciò comporta che queste due gonadotropine abbiano una diversa attività endocrina, nonostante siano state utilizzate per lungo tempo come equivalenti nella pratica clinica.
