Kwezinye izimo, ngemuva kokusebenzisa inqubo yokufaka umanyolo we-in vitro, odokotela ngokwabo benza ukuchotshozwa kwalesi sigobolondo, ngaleyo ndlela basize umbungu ukuba utholakale emgodini we-uterine. Ngokusho kochwepheshe abaningi abathintekayo kwinkqubo ye-IVF, le nqubo ivame ukusiza ekukhulelweni kokuqala. Ukuxhashazwa okunjalo kubizwa ngokuthi "ukuxoshwa kwemibungu ensizayo".
Lolu hlobo lokuxhaphaza lwenziwa kanjani?
Njengoba sibhekane neqiniso lokuthi lokhu kushayisana ohlelweni lwe-ECO, ake sikhulume ngokucacile ukuthi yikuphi okuphawulekayo kwalokhu kukhishwa.
Njengomthetho, kunqunywe kulawo macala lapho imizamo yangaphambilini yokukhulelwa ngosizo lwe-in vitro fertilization kwabesifazane iphelile ngempumelelo.
Ngokwalo, ukuxhaphazwa kubhekisela esigabeni semikhiqizo emincane futhi kwenziwa ngaphansi kwe-microscope ngenyuka enkulu. Lapho kwenziwa endaweni ye-pellucida, udokotela wenza ukuchotshozwa, futhi ngemuva kwalokho kuphela, umbungu usungulwa ngqo emgodini wesibindi. Okusho ukuthi, ngamanye amazwi, - odokotela benza ngokukhethekile imbobo yokwenza ukusiza ukuba athole indawo emdongeni wesibeletho.
Ochwepheshe emkhakheni we-IVF bathi lolu hlobo lwenqubo luyakwandisa kakhulu amathuba okukhulelwa kwabesifazane emva kweminyaka engama-35, futhi kusiza nalabo besifazane abanesifo sokungaboni kahle nge-etiology, abangafundanga ngokugcwele.
Ngabe iziphi izimo ukuvinjelwa kwama-embryo okungabhalwa nge-IVF?
Ngenxa yokuthi ukukhwabaniswa okwenziwe phakathi nalokhu kuqhutshwa kulinganiswa ngamanometer amaningana, kwenziwa ngokusebenzisa i-laser ekhethekile, ngakho-ke igama lenqubo.
Ezingxenyeni ezihlukahlukene ze-intanethi, ungathola ukubuyekezwa kwamamama angabonwa ukuthi ukuchitha kuyinto engelusizo kanye nokuchitha imali eyengeziwe. umphumela wenqubo enjalo yi-zero. Eqinisweni, lokhu akunjalo. Ucwaningo oluqhutshwa ochwepheshe baseNtshonalanga ku-IVF luqinisekisile ukuthi ukuhlaselwa kwe-pellucida kuvumela ukwandisa amathuba okufakwa endaweni engaphezu kwama-50%. Kodwa-ke, kubalulekile futhi ukucabangela iqiniso lokuthi noma ngabe ukuxoshwa kwenziwa, lokhu akuqinisekisi ukuthi umbungu we-embryo ofika e-ECO uzohlale uphumelela.
Into yukuthi inqubo yokufakelwa iminyango yinkimbinkimbi, kusukela ekubukeni kwezinto eziphilayo. Futhi noma ngabe ukuqubuka kwemvilophu yangaphandle ye-embryo kuye kwenziwa, lokhu akukona isiqinisekiso sokuthi ukulungiswa kwe-endometrium kwesibeletho kuyophumelela.
Ukuze ukwandise amathuba okukhulelwa, odokotela batusa inqubo yokuqothula kulezi zimo ezilandelayo:
- unyaka wesifazane uneminyaka engaphezu kwengu-35;
- amazinga egazi aphezulu we-horlicone-eshukumisa i-hormone;
- Uhlobo olungalungile kanye nephesenti yokuhlukaniswa kwe-blastomere ngesikhathi se-embryogenesis;
- ubukhulu obukhulu bendawo ye-pellucida embryo (ngaphezu kuka-18 nm).
Le nqubo iyadingeka lapho isibonakaliso se-blastomer sidlula ngo-10% noma ngaphezulu, futhi ngaphambi kokuba umbungu, isibalo se-blastomeres singaphansi kuka-6.
Ukuvinjelwa okusizayo kunqatshelwe ezimweni lapho i-embryo blastomeres engekho phakathi kwe-meiosis 1.
Ngakho-ke, njengoba kubonakala kulesi sihloko, ukuxoshwa kuyindlela ebaluleke kakhulu ekusetshenzisweni kokukhulelwa kwe-in vitro, okusiza ngezinye izikhathi ukwandisa amathuba okufaka umbungu ku-endometrium yebele bese ubambe iqhaza ekukhulelweni.
