Uma owesifazane ekhetha indlela enjalo njenge-IVF njengendlela yokwelashwa kokungazalwa, khona-ke uzobe esenikwa ukwelashwa kwe-hormone ukuze ukwandise ukukhiqizwa kwezinhlobo ezinhle zomzimba ngomzimba wakhe.
Ngemva kwalokhu, amaqanda aya embukisweni wezinambuzane, ozoqondile futhi ozokwenza umanyolo.
Njengomthetho, ama-embryus angaphezu kuka 2-3 afakwa esibelethweni sowesifazane. Okunye okunye, uma kunesidingo, abesifazane bangabekwa ngaphansi kwe-cryopreservation noma iqhwa. Uma umphumela ongaphumeleli womzamo wokuqala we-IVF, imibungu eqhwayo isetshenziselwa okwesibili noma uma kwenzeka ukuthi ngemuva kokuzalwa kwengane yokuqala owesifazane ufuna ukuzala okwesibili.
Ukudluliselwa kwemibungu emva kokukhishwa kwe-cryopreservation
I-Cryopreservation iyindlela eqinisekisiwe yokusiza ubuchwepheshe bokuzala. Amathuba okukhulelwa ngenxa yokudluliswa kwemibungu emva kokukhishwa kwe-cryopreservation cishe kuncane kunesimo semibungu esanda kutholakele. Kodwa-ke, ochwepheshe bokubeletha batusa ukuthi iziguli zabo zigcwale imibungu ezishiywe ngemuva kwenkambiso, njengoba umjikelezo wokushisa nokudlulisa imibungu ebizwa ngokuthi yi-cryopreserved iyabiza kakhulu kunomjikelezo omusha we-IVF.
Ama-embryos angama-50% avunyelwe kahle ngokukhishwa ngamanzi. Ngesikhathi esifanayo, ingozi yokukhulisa i-pathologies enganeni ebusweni ayikhulumi.
Kungenzeka ukuthi umise ama-pronuclei, umbungu ochotshoziwe, i-blastocyst uma unekhwalithi ephezulu kakhulu yokudlulisela
Imibungu ixubene nomphakathi okhethekile obavikela emonakalweni - i-cryoprotectant. Ngemuva kwaloko, zifakwa emthonjeni wepulastiki bese zihlile kuze kube ngu -19 ° C. I-metabolism yamaseli akuleli lokushisa imisiwe, ngakho-ke kungenzeka ukugcina ama-embungu kulo mbuso amashumi ambalwa eminyaka.
Isilinganiso sokusinda semibungu ngemva kokuhlukunyezwa kungama-75-80%. Ngakho-ke, ukuze uthole ama-embruse aphezulu angu-2-3 wokuphindaphinda esibelethweni, kuyadingeka ukuba ukhululeke imibungu eminingi kakhulu.
