*'''<span style="color:#ff0000">Function:'''
** '''<span style="color:#ff0000">Stimulates Sertoli cells'''
***'''<span style="color:#ff0000">Major stimulator of seminiferous tubule growth'''
***'''Essential for initiation of spermatogenesis at puberty''' '''but not essential for spermatogenesis in acquired infertility (i.e. after puberty)'''
****'''Clinical implication: infertility can be treated with hCG hormonal therapy monotherapy without concomitant recombinant FSH'''
