Ukuba umfazi ukhetha indlela efana ne-IVF njengendlela yokonyango kokungabikho kwengqondo, ngoko uya kuqala ukunika unyango lwe-hormone ukwenzela ukwandisa umgangatho wezinto ezilungileyo zomzimba ngomzimba wakhe.
Emva koko, amaqanda aya kwi-embryologist, ngokuthe ngqo kwaye iya kuzalisa.
Njengomthetho, akukho ma-embrasi angama-2-3 afakwe kwisisu somfazi. Eminye indawo, ukuba ifunwa, abafazi banokuxhomekeka kwi-cryopreservation okanye ngeqhwa. Nangona umphumo ongaphumelelanga wokuzama ukuqala kwe-IVF, iimbumba ezincinci zisetyenziselwa okwesibini okanye kwimeko ukuba emva kokuzalwa komntwana wokuqala umfazi ufuna ukuzala okwesibini.
Ukutshintshwa kweembungu emva kwe-cryopreservation
I-cryopreservation yindlela echanekileyo yokuncedisa ubuchwepheshe bokuzala. Ubunokwenzeka bokukhulelwa ngenxa yokutshintshwa kwama- embropreservation emva kwe-cryopreservation ingaphantsi kwimeko kunye nama-embrys asanduliweyo. Kodwa ke, iingcali zokuzala zincoma ukuba izigulane zabo zenze iimbumba zishiye emva kwenkqubo, njengoko umjikelezo wokubanda kunye nokutshintshisa ama-embropreserved embryos kuncinci kunomjikelezo omtsha we-IVF.
Phantse i-50% yeembrusi ixhomekeke ngokukhwabanisa. Ngelo xesha, umngcipheko wokwakha i-patenas congenital in the fetus ayanda.
Kuyakwazi ukukrazula i-pronuclei, i-embryo echotshoziweyo, i-blastocyst ukuba inomgangatho ophakamileyo ophezulu wokutshintshwa
Iimbrusi zixutywe kunye nesimo esikhethekileyo esibakhusela umonakalo - i-cryoprotectant. Emva koko, zifakwe kwi-plastic straw kunye ne -196 ° C. I-metabolism yeeseli kule fudusi imisiwe, ngoko ke kunokwenzeka ukuba kugcinwe ama-embra kulesi sikhundla iminyaka emininzi.
Inani lokusinda kweembryi emva kokuphazamiseka ku-75-80%. Ngoko ke, ukufumana ii-embrasi eziphezulu eziphezulu ezi-2-3 zokutshintshela kwi-uterus, kuyadingeka ukuba ungabhubhisi iimbumba ezininzi.
