Ixesha kwixesha elilandelayo, isigaba ovulation, iintsuku ezintathu. Ngeli xesha kwinqanaba snizhet of hormone follicle-ekhuthazayo, leyo ukunika indlela eya luteinizing eyenza uyamkela ukuba namadlozi yencindi yomlomo wesibeleko. Ngapha koko, le hormone ichaphazela ukugqitywa of kweqanda nokwanda, emva kokuba iphume follicle (ovulation). iqanda zavuthwa eshenxela ityhubhu Imibhobho, apho malunga ezimbini iintsuku ukulinda de isichumiso.

Ngaba indawo yi kwisigaba sesine sexesheni - luteal. Emva kokukhutshwa follicle iqanda, iyithumele kwezichumiso, kwaye follicle uqala imveliso yiprogesterone.

Ukuba ekukhulelweni akukho kwenzeke, iqanda kunye nomzimba etyheli uyafa, uyayeka ukuvelisa dlala, kuba nakanjani kulandela ukutshatyalaliswa kunye ukwaliwa endometrium. Ngamanye amazwi, uqala ngenyanga, yaye zonke izigaba sexesheni landela omnye komnye kwakhona.

Ephawulekayo kuba enyanisweni elandelayo. Zonke izigaba ezine sexesheni ziyaphuhliswa phantsi kweempembelelo emzimbeni, echaphazela kuphela amalungu, kodwa kurhulumente ngokweemvakalelo yabafazi.
