Asi panguva ipi zvayo yevarume, huwandu hwavo hunogara huripo, uye muvakadzi ikoko pachava nekuchinja, zvichienderana nezera uye chikamu chekuenda kumwedzi. Muvana, prolactin yakaderera, uye kuwedzera kwayo kunotanga kuvasikana pavanenge vachiri kuyaruka.
Uyewo, kuwedzera kwehommone prolactin kuvakadzi kunonzi physiologically yakacherechedza panguva yekuzvitakura uye kwenguva yekuyamwisa. Inogona kuve yakakwirira mumadzimai mushure mekuita zvepabonde kana kukurudzirwa kwezvikovo, mushure mekushungurudzika kwakanyanya, uye panguva ino hazvibvumirwi kupedza muedzo weprolactin . Prolactin uye nehuwandu hwayo muropa rinopikisa madzimai emadzimai evanhukadzi, kunyanya kusaenzana kwehomoni. Uye mushure mokunge apera, chirwere cheprolactin chinogona kuderera zvishoma.
