I-vitrification yesisu

Lolu hlobo lwenqubo, njenge-vitrification yemibungu, ingenye yezindlela zokwenza i- cryopreservation (iqhwa). Isetshenziswe uma kubalulekile ukuhlehlisa kabusha i-protocol ye-IVF. Ngokusungulwa kwalendlela, kwakungenzeka ukuba ngcono kakhulu izinga lokusinda kokubili amasondo omzimba kanye nemibungu emva kwenqubo yokuqhafaza.

Kuyadingeka nini ukuba iqede imibungu?

Kumele kuqashelwe ukuthi i-cryopreservation ingenziwa kunoma yisiphi isigaba sokuthuthukiswa (i-pronucleus, i-embrying crush, i-blastocyst). Ngoba inqubo ingasetshenziswa cishe nganoma isiphi isikhathi, lapho kunamathuba okuphumelela ekufikeni kwesibeletho.

Ngokuqondene nezinzuzo ezisheshayo zokuqhwaza, phakathi kwalezi kufanele zibizwa ngokuthi:

1. Amathuba okukhulelwa okukhulelwa emva kwe-IVF nokuvimbela ukufa kwemibungu evamile, eyenza ukwazi ukuwasebenzisa emva kokufaka umanyolo we-in vitro.
2. It kuvimbela imiphumela ye-hyperstimulation phambi kwendlela ephakeme yokuthuthukiswa kwayo.
3. Kuyisisombululo senkinga lapho ukuvumelanisa kwemijikelezo yokuya esikhathini yomnikeli nomamukeli akunakwenzeka.

I-cryopreservation yemibungu ngokusebenza kwe-vitrification iphoqelekile uma:

• kunciphisa amathuba okufakwa emgodini wesibindi, ngenxa yokuthi kukhona ukuphazamiseka kwithoko lokuzala (i-polyps, isibonelo);
• stenosis yomsele womlomo wesibeletho (akukho catheter ingafakwa ngomngcwabo womlomo wesibeletho).

Ukushisa kubuthinta kanjani umbungu?

Esikhathini sezifundo eziningi zokuhlola, kwafunyanwa ukuthi ukwenza le nqubo akusizi lutho ekuthuthukiseni phambili kombungu. Ngakho-ke, uma kunesidingo, i-biomaterial ikhishwa ku-capsule ene-nitrogen eyetshezi, ishiywe ekushiseni kwama-20-22 degrees, ngemva kwalokho i-cryoprotectant isusiwe futhi umbungu ubeka endaweni ekhethekile. Ngemuva kokuhlola isimo sombungu, qhubeka enqubo yokutshala.
