Mapatya anozvarwa mune chete 2% yevese vanozvarwa. Uyezve, mapatya anogona kuve akapetana (akafanana kune vamwe sehama dzepedyo dzepedyo) uye akafanana (ane chitarisiko chakafanana). Muchikamu chino, iwe uchaona kuti chii mukana wekuve nemapatya, izvo zvinoenderana nazvo uye kana uchigona kuwedzera kana kuideredza.
Ndeupi mukana wekuve nemapatya?
Kazhinji kazhinji, kugona kubata pamuviri pemapatya kunopfuura nepanhengo yechikadzi. Vamiriri vebonde rakasimba vanongopfuudza kugona uku kune vanasikana vavo kana paine zviitiko zvekuonekwa kwemapatya mumhuri yavo. Kune zvakawanda zvinhu zvinokanganisa mukana wekubata nhumbu kwakadai.
1) Maumbirwo. Pakange paine mapatya mumhuri, mukana wekuburitsa akati wandei evacheche pasirese unova wakakura kwazvo. Asi mukana wekuve nemapatya unodzikira nechizvarwa chemapatya ari kure munguva.
2) Zera ramai vakatarisira. Mune mukadzi akura, muviri unoburitsa mahormone akawanda. Ndiwo iwo akakosha paramende yekukura kwezai, uye nekuwedzera kwenhamba yemahormone, mukana wekuburitswa panguva imwe chete kwemazai akati wandei unowedzera.
Vanhukadzi vane makore makumi matatu neshanu nemakumi matatu neshanu ekuberekwa vane mikana chaiyo yekuzvara vaviri vevana panguva imwe chete.
3) Nguva yenguva yemasikati. Chinhu ichi zvakare chinokanganisa kugadzirwa kwemahormone anodikanwa. Iyo yakanyanya kunaka nguva yekuzvara mapatya chirimo, apo masikati machena anova akareba.
4) Nguva yekutevera. Mukana mukuru wekutora mapatya ndeaya evakadzi vane kumwedzi uko kusingapfuuri mazuva makumi maviri nerimwe.
5) Mukana wekuonekwa kwemapatya unowedzerawo muvakadzi vane hutachiona hwehutachiona hwechibereko (kune zvipenga mudumbu renhengo yekubereka kana chibereko chakabvaruka).
6) Kutora mishonga yekudzivirira. Izvo zvinotungamira kuchinjiro mukugadzirwa kwehuwandu hwehomoni, izvo zvinowedzera mikana yekukora kwemazai akati wandei. Iyo mikana yekuve nevana vaviri vacheche inowedzera kana nhumbu ikaitika nekukurumidza mushure mekushandisa mishonga yekudzivirira, iyo yakatorwa kwemwedzi mitanhatu.
7) Insemination yekugadzira. Kazhinji kazhinji, neiyi nzira yekusangana, mapatya uye kunyange matatu anozvarwa, anoitika achitora mahormone zvinodhaka.
Kunyangwe paine chokwadi chekuti vanachiremba havasati vanyatsodzidza nezvechiitiko chekuzvarwa kwemapatya, unogona achiri kuwana mikana yekuve nemapatya kana ukatendeukira kune genetics. Kuti uite izvi, iwe uchafanirwa kuita bvunzo chaiyo uye udza chiremba nezvezvizukuru kubva kuchizvarwa chechina.
