Izibini ezitshatileyo eziye zahlaselwa yintlekele enjalo, zama ukuqonda indlela kwaye kutheni kwenzeka, kwaye ukhathazeke kakhulu ngesiphumo sokukhulelwa okutsha. Okwangoku, ukuzalwa komntwana onempilo emva kokutshatyalaliswa komntwana kubonakala kunokwenzeka, ngakumbi xa ufumana zonke iimviwo eziyimfuneko kwaye uzilungiselele ngokukhulelwa ngokuchanekileyo.
Kule nqaku, siza kukuxelela ukuba zeziphi iimvavanyo ezithatha emva kokukhulelwa okukhuselekileyo ukuze uzikhusele kwaye ufumane isizathu sokuba umntwana omile ekuphuhlisweni.
Ziziphi iimvavanyo endingazithatha emva kokukhulelwa okukhuni?
Ukuze kuqinisekiswe isizathu esiyintloko sokukhulelwa, kufuneka uphumelele ezi zilandelayo mvavanyo:
- Eyokuqala, emva kokukhulelwa okukhuni, uhlalutyo lwenziwe kwi-histology. Le ndlela isifundo sezicubu ze-embryo phantsi kwe-microscope emva kokutshiza. I-Histology ivumela ukukrokra okanye ukungabandakanyi izizathu zokutshatyalaliswa komntwana njengokuguquka kofuzo, ukuphazamiseka kwe-hormonal, ukusuleleka kumachiza ezincinci, izifo ezingapheliyo zomama ozayo kunye nabanye. Kwimeko nayiphi na imeko, iziphumo ze-histology maziqinisekiswe ezinye izifundo.
- Ukuba kukho ukukrokra kweengxaki ze- hormone, ukuhlolwa kwegazi olufanelekileyo kwenziwa.
- Emva koko, kuyimfuneko ukuqhuba isifundo esiyinkimbinkimbi ekufumaneni izifo ezithathelwana ngesondo - ziyakuchukumisa kakubi imbryo.
- Kwakhona, emva kokukhulelwa okhenkce, unokwenza uhlalutyo lwe-genetic, okanye i-chromosome, uhlalutyo lwe-fetus ukucacisa i- karyotype. Ngethuba le sifundo, i-geneticist efanelekileyo iya kuba nako ukunquma ukuba ngaba abazali bomntwana basasaza izifo ezibangelwa imvelaphi ekhokelela ekulahlekeni kwamathambo kunye nokubola komntwana. Uhlalutyo kwi-genetics emva kokukhulelwa kokufa kuyabiza kakhulu, kodwa ukuba imeko yombungu ebanjwe ekuphuhlisweni akuyona eyona yokuqala, inokwenziwa ngokukhululeka kwinqanaba loogqirha.
