I-cryopreservation ye-oocytes, imbrusi

Ukuchithwa kwee-oocytes kunye nama-embrosi yeendlela ezimbini ezahlukeneyo ezisetyenziswe kwi-IVF kunye nokwandisa impumelelo yayo. Masiqwalasele ngokuthe ngqo kwaye sitsho malunga nezinto zabo eziphambili.

Yintoni i-cryoconservation ye-oocytes?

Le ndlela ithathwa njengoluhlobo lwe teknoloji yokulinga. Le nto yinto edlalwa xa iqhutyelwa, izinga lokusinda kwama-oocytes emva kokuqhwaqisa kakhulu. Ukongezelela, iseli lesini, emva kokuthabatha kunye nokubeka kwiididi eziphathekayo, asinakuhlala utyalwa.

Ukuphumelela kweli ndlela kunokuthi ulungele kuphela ukuba ibhinqa ayinayo iqabane lesini okanye ayilungele ukuba ngumama. Kwiimeko ezifanayo, oku mhlawumbi yithuba elilodwa lokuba ukhulelwe kwaye unomntwana. Njengezithunywa ezisetyenziselwa ukukhupha ii-oocytes, i-cryoprotectants njenge-ethylene glycol kunye ne-dimethylsulfoxide inokusebenza. Ukuchithwa kwamaqanda nakho kunokukwenziwa ngendlela efanayo . Kufuneka kuqatshelwe ukuba ubude bokugcina asithinteli ukusinda nganoma iyiphi indlela.

Yonke into incike kwizinto ezibizwa ngokuba yizakhiwo ze-oocytes. Ngako oko, ngaphambi kokuba wenze inkqubo enjalo, ukhetho olubalulekileyo lukhethwa ngokukhethekileyo, oluqhutywa ngokuhlola ii-oocytes kwi-microscope ekhethekileyo.

Ngokwezibalo zengqapheli, izinga lokusinda kwama-oocyte anqabileyo li malunga nama-68%, ngelixa ubude bezochumiso babo bunama-48%. Ukuba sithetha ngobunzima bokubona ukukhulelwa kwi-oocyte nganye echwayibhileyo, oku kubakho kwi-2% yamatyala.

Yintoni i-cryopreservation ye-embryo?

Olu hlobo lokuqhawulwa kwe-biomaterial kwinkqubo ye-IVF elandelayo luya phambili. Into leyo kukuba ama-embropreservation embrospers give in best.

Ukusetyenziswa kweli cwangciso kuvumela inkqubo yokuchumisa in vitro ukuba yenziwe ngomjikelezo omnye. Ngoko, xa kwenzeka ukuba emva kokufakelwa kwendawo yokukhulelwa kwe-embriyo ekhulayo, ungasebenzisa i-cryopreserved, kwaye ungahlakuleli entsha kwi-medium medium.

I-cryopreservation ye-embrasi ine-pluses kunye ne-minuses yayo. Iyokuqala ingaquka:

• Ukunciphisa iindleko kunye neendleko zezinto eziphathekayo kwi-IVF (i-media media is expensive);
• ukunciphisa ubude benkqubo;
• ithuba lokuphinda i-IVF emva kwexesha elide.

Iingxaki ezingundoqo zolu hlobo ziquka into yokuba ukukhulelwa ku malunga nama-60%, kwaye izinga lokusinda kwama-embryo emva kokutshatyalaliswa kwazo kuninzi lwezinto ezihamba phambili, ukusuka kwi-35 ukuya kwi-90%. Ukubonelelwa kwezi ngqinani, kunzima ukuqikelela indlela ama-embryos aza kuzaliswa ngayo emva kwe-cryopreservation.
