Zvinonyatsozivikanwa kuti mikana yekuberekwa kwomwana inonyanya kuitika pazuva rekuvhara. Pasi pemuvulation kunonzwisiswa nzira yekubuda kubva muvharo yemukoro wakakwana. Iyo isina kuvharirwa mazai haisi kusiya mahara, iyo inowanzova chigumbuso panzira inoenda kumimba inoda.
Kuti udzidze nzira yekutsvaira mazai pazuva rechisere kana kuti repfumbamwe yekuenda kumwedzi, ultrasound inofanira kuitwa.
Iyo nzira yekusimudza mazai inoita seyizvi: mumuchivhiri chemusikana achangoberekwa pane mazai evha akapoteredzwa ne follicles. Vanotanga kukura mumakore ekuyaruka - mushure mekugadzirwa kwemwedzi. Evha inobhururuka muhafu yekutanga yemhepo. Mushure mokunge ruzivo rwuri maibva, rwunotamirwa kunheyo yenheyo, hutachiona hunoshanduka, uye kana hormone iri muropa ichikanyanya zvikuru, mazai anosiya mavhiri mudumbu remuviri. Kubva ipapo, anopinda mumugwagwa we fallopian, achimirira musangano nehuta. Mushure mokuputika, hutano hweii huripo kwezuva. Kana panguva iyi yekudyara haina kuitika, inotaura nezvekufa kweii.
Kazhinji, munguva yehupenyu hwemukadzi, kubva pakuvamba kwekuyaruka kusvika pakupera, imwe yenyuchi inobhururuka mwedzi muvharo. Izvi zvinotungamirirwa nehutano hwekubereka. Kana mazai asingabvumi - inosanganisira kukwanisa kubata mwana. Izvo zvinogona kutaurwa nezvimwe zvinetso mukukudziridza kwema ovum, somuenzaniso, nezvehutano hwewavo isina chinhu.
Sei mazai asina kubvaruka?
Muzviitiko zvakawanda, chikonzero chekuti neiii risingabvumi iko kukanganisa kwemashure ehomoni kana kusashanda mukushanda kwezvinyorwa zve endocrine. Zvisinei, kusununguka kweii kunogona kusanganiswa nezvimwe zvinhu, somuenzaniso:
