Amawele amancane (izingane ezimbili noma ngaphezulu) ngesikhathi esifanayo zikhula esibelethweni sowesifazane futhi zizalwa ndawonye. Umama ozayo ukukhulelwa okuphindaphindiwe ngumthwalo ophindwe kabili, futhi ujabula kakhulu.
Amawele amabili angaba yindlala futhi i-raznoyaytsevye. Esikhathini sokuqala, ukukhulelwa okuningi kungumphumela wokuhlukanisa iqanda elilodwa elifakwe emanzini. Ake sihlolisise ukhetho lwesibili.
Amawele ahlukile athola kanjani?
Icala lokuqala lapho iqanda elilodwa emva kokuhlanganiswa ne-spermatozoa elilodwa lihlukaniswe lababili. Ngakho-ke, esibelethweni sowesifazane, ama-fetus amabili (noma ngaphezulu) aqala ukuthuthukisa ngesikhathi esisodwa.
Elinye icala livame kakhulu, lapho amawele omndeni ezalwa ngenxa yokukhulelwa kwama-ovules amabili emjikelezweni owodwa wokuya esikhathini.
Ngokuvamile, ukukhulelwa okunjalo kwenzeka kwabesifazane emva kweminyaka engama-35. Lokhu kubangelwa izinguquko ezihlobene nobudala ohlelweni lwe-hormonal, ngenxa yalokho ama-ovules amabili noma ngaphezulu anakho ukukhulelwa angavuthwa phakathi nomjikelezo owodwa.
Futhi, ukuzalwa kwamawele e-heterozygous ngokuvamile kwenzeka emva kokwelashwa kwama-hormonal noma ukuyeka ukusetshenziswa kokukhulelwa, tk. Kulezi zimo uhlelo lokuzala lokubeletha lusebenza ngamandla.
Izidingo zokukhulelwa okuningi:
- Umama uneminyaka engaphezu kwengu-35 ;
- Ubufebe: uma amawele emndenini azalwa ekuqaleni (emgqeni womama);
- ukuthatha izidakamizwa ze-hormonal;
- okuvela emncintiswaneni othile (isibonelo, kuphawulwe ukuthi inani elikhulu lamawele lizalwa ezizweni zase-Afrika, ngaphansi kokunye - emncintiswaneni wamaMongolia).
Ukukhulelwa okuphindaphindiwe kungaphansi kokuhlolwa kodokotela. Ukubeletha ngokuvamile kuvame ngaphambi kwesikhathi esihleliwe. Isisindo sezinsana singaphansi kokukhulelwa okukodwa.
Uma ukukhulelwa kwakungekho izinkinga futhi ukuzalwa kwaphumelela, ukuphila okuqhubekayo kwezinsana nabazali kuqhubeka nanoma yimuphi umndeni lapho ingane ivele khona. Lapha kuphela izingane ezingekho lapha, kodwa eziningana.
Amawele omndeni afana nokufana nabazalwane nodade abavamile. Zinezinhlobo ezahlukene zezakhi zofuzo futhi zingase zivela kobaba abahlukahlukene. Ngakho-ke, ngokungafani namawele afanayo, akumangalisi uma banezinhlobonhlobo zamehlo nezinwele, izinhlamvu ezahlukene namazinga okuthuthukiswa.
