Ukusukela ekufikeni koqingqo-nzala lwasetyhini ngoo-1950 ukuya ekuzalweni komntwana ityhubhu yovavanyo ngo-1970 kunye nokwenziwa ngempumelelo kweegusha ze-Dolly ngasekupheleni kweminyaka yoo-1990, iteknoloji yeyeza lokuzala yenze impumelelo enkulu itekhnoloji yokunceda abantu ekuzaleni (UbuGcisa) ubukhulu becala bubuchwephesha obukhethekileyo. ukunceda ezo zigulana zisengakwazi ukukhulelwa emva konyango oluqhelekileyo ukudibanisa amaqanda kunye nesidoda phantsi kweemeko zebhubhoratri ukuphumeza ukukhulelwa.Njengoko le teknoloji ihlukanisa ngokupheleleyo isondo kunye nokuzala, ukuphuhliswa kwayo ngokukhawuleza kuye kwazisa uluhlu lweengxaki zokuziphatha, ezisemthethweni kunye nezentlalo, okwenza uphuhliso lobugcisa luhluke kakhulu kwezinye iindlela zonyango, lube liyeza elikhula kwiingxabano.
Ubudlolo sisifo senkqubo yokuzala esibonakala ngokusilela ukukhawula ngokwezonyango emva kweenyanga ezili-12 okanye ngaphezulu kwesondo esiqhelekileyo ngaphandle kokukhulelwa.Ukuxhaphaka kwehlabathi lokungabikho komntwana kuye kwanda ukusuka kwi-11% kwi-1997 ukuya kwi-15.4% ngo-2018, kwaye kulindeleke ukuba kunyuke ukuya kwi-17.2% ngo-2023. I-2023, ngelixa ukuxhaphaka kokungabikho komntwana e-China kulindeleke ukuba kunyuke ukusuka kwi-16.0% kwi-2018 ukuya kwi-18.2% kwi-2023.
