Kispeptin učestvuje u regulaciji endokrinih funkcija i početka puberteta. Aktivacija kispeptinskog receptora inicira otpuštanje gonadotropin-oslobađajućeg hormona (GnRH).[7][8] Otpuštanje samog kispeptina inhibira estradiol, a podstiče GnRH.[9] Snižavanje nivoa kispeptina sa godinama je jedan od mogućih razloga za opadanje nivoa drugih endokrinih hormona, kao što je luteinizirajući hormon.[10]
