Namuhla, abesifazane bavame ukubeletha kamuva. Ngesinye isizathu, owesifazane uzama ukuhlehlisa ukukhulelwa nokubeletha. Ngokuvamile lokhu kubangelwa isifiso sokuthola ukuzimela kwezezimali, ukukhuphuka izinga lezemisebenzi, noma nje ukungabi khona komlingani ofanelekayo. Kungenxa yamacala anjalo okucatshangelwa ukuthi i-cryopreservation yeqanda. Lolu buchwepheshe landisa amathuba okuba nengane enempilo esikhathini esizayo. Futhi uma kwenziwa i- IVF cryopreservation sekuvele kube yinto evamile futhi evamile.
Iyini i-cryopreservation?
I-cryopreservation yeqanda yinkqubo yokugcinwa kwayo efomini elifriziwe, ngokubuyiselwa kwemisebenzi ngemuva kokuqeda. Ngaphambilini, ukugcinwa kwe-cryoconservation yamaseli wesini wesifazane kwakungenakulinganiswa, ngoba indlela yokugcoba kancane yayisetshenziswa. Kwakulukhuni kakhulu ukungalimazi isakhiwo sekhanda ngenxa ye-crystallization ngesikhathi sokupholisa. Ngenxa yalokho, amangqamuzana amaningi ayengenakwenzeka emva kwe-cryopreservation-thawing.
Indlela ye-vitrification manje isetshenziselwa i-cryopreservation yama-oocyte (amasondo omzimba). Ngenxa yalendlela, leli qanda liqhwa ngokusheshisa, lidlula isiteji sokwakhiwa kwamakhemikhali, okwabhubhisa isakhiwo saso. Ukusinda kwamaqanda nalokhu kupholisa kuye kwanda kakhulu. Yini eyenza i-vitrification inqubo ethembisayo emkhakheni wezokwelapha zokuzala.
Izinzuzo ze-cryopreservation amaqanda
Ukuchithwa kwamaqanda kunezinzuzo eziningana kokubili kokuziphatha nokuziphatha:
- Owesifazane angafisa amaqanda ayo amancane, futhi abelethe ingane ngesikhathi esivuthiwe. Singasho ukuthi ama-ovules alahlekelwa yikhwalithi yawo eminyakeni. Futhi eminyakeni engama-20, owesifazane unamathuba amaningi okubeletha umntwana onempilo, kunama-35-40.
- Kukhona umqondo wama-oocyte a-cryopreserved ngenxa yezizathu zezokwelapha. Isibonelo, i-oncology ngaphambi kwe-chemotherapy, abesifazane abaphethwe yi-endometriosis (isifo esibangela ukukhubazeka kwe-ovarian).
- Kuyinto enengqondo ukusebenzisa leyo friji emjikelezweni we-IVF. Ngemuva kokuvuselela ukuvuthwa, owesifazane angakhulela amaqanda angu-15, kuyilapho imibungu emibili kuphela ingafakwa esibelethweni. Okunye okunye kungashiywa uma kwenzeka ukukhulelwa kwesisu noma uma kukhona isifiso sokubeletha enye ingane. Ukwehliswa kweqanda kuzodla imali eshibhile futhi iphephile kowesifazane kunokuqala ukwenza inqubo yokuvuselela, ukukhishwa nokunye okunjalo.
- Ngenxa yezizathu zokuziphatha, ukuqanda amaqanda kungcono kune- cryopreservation yemibungu eqediwe . Ngenxa yokuthi ekupheleni kwesikhathi ekuphileni kwabantu, okuningi kuguquka. Abashadile bangahlanganyela noma kukhona namanje izizathu eziningi zokuthi kungani ama-embriyo ehlala engavunyelwe abazali bawo bezakhi zofuzo. Lokhu kuhlanganisa izinkinga eziningi esikhungweni sezokwelapha, lapho imibukiso efriziwe igcinwa khona, njengoba umthetho wanamuhla ungakanikeli izimo ezinjalo.
Ngokusho konke okushiwo ngenhla, kungaphetha ngokuthi ukwenziwa kwamaqanda amaqanda kuyindlela eqhubekayo emkhakheni wokuzala. I-vitrification yamangqamuzana yenza kube lula abesifazane besifazane ukuba bathole injabulo yokuba ngumama. Lena yithuba elihle kakhulu lamabhangqwana abangenabantwana ababazali abangenaye umntwana oyedwa. Futhi, abesifazane abangashadile banikeza ithemba esikhathini esizayo ukuze babe ngumama wengane enempilo.
Ngokwezibalo, izingane ezizalwa ngosizo lwe-cryotechnology azifani nalabo abakhulelwe ngendlela evamile, yemvelo. I-Frost ayinakwandisa ingozi yokuthuthukisa i-pathologies yokuzalwa. Ngokuphambene nalokho, singabona ukuthambekela kokukhethwa kwemvelo, ngoba emva kokuba inqubo yokupholisa inhlanzi kuphela i-oocyte ephakemeyo iphila.
