Ngaphambi kwe umthetho we-bioethics eyamukelwa yiSishayamthetho Sikazwelonke ngoJuni 29, 2021, ukuzivikela kwama-oocyte kwagunyazwa ezimweni ezimbili kuphela: kwabesifazane ababezolashwa umdlavuza kanye nalabo ababefisa ukunikela ngama-oocyte abo kwabanye. Kusukela ngo-2021, noma yimuphi owesifazane manje - ngaphandle kwesizathu sezokwelapha - ngakho-ke - acele ukuzivikela ama-oocyte akhe. Uma izinhlinzeko eziqondile zichazwa ngomthetho, ukuvuselela nokubhoboza kunganakekelwa ngokuPhepha Komphakathi, kodwa hhayi ukongiwa kwemvelo, okulinganiselwa cishe kuma-euro angama-40 ngonyaka. Izikhungo zezempilo zomphakathi kuphela, noma uma zihluleka izikhungo ezizimele ezingenzi nzuzo, ezigunyazwe ukwenza lokhu kungenelela. EFrance, amawele u-Jérémie noKeren ayizingane zokuqala ezizalwa zisebenzisa le ndlela.
I-Vitrification ye-oocyte
Kunezindlela ezimbili zokugcina ama-oocyte: iqhwa kanye ne-vitrification. Le ndlela yokugcina ye ukuqandisa okusheshayo kwama-oocyte isebenza kahle kakhulu. Isekelwe ekwehleni kwezinga lokushisa ngaphandle kokwakheka kwamakristalu eqhwa futhi ivumela amaqanda amaningi avundiswa ukuba atholakale ngemva kokuncibilika. Ukuzalwa kokuqala, ngenxa yale nqubo, kwenzeka ngoMashi 2012 esibhedlela saseRobert Debré eParis. Umntwana womfana wazalwa ngokwemvelo emasontweni angama-36. Unesisindo esingamakhilogremu angu-2,980 futhi ubude bakhe bungama-48 cm. Le ndlela entsha yokuzala imelela ithemba langempela kwabesifazane abafuna ukulondoloza inzalo yabo futhi babe ngumama, ngisho nangemva kokwelashwa okunzima.
