Namhlanje, abasetyhini banomdla wokuzala abantwana. Ngesizathu esithile, umfazi uzama ukuyeka ukukhulelwa nokubeletha. Ngokuqhelekileyo oku kubangelwa ngumnqweno wokufumana ukuzimela kwemali, ukunyuka kwinqanaba lomsebenzi, okanye ngokungabikho kweqabane elifanelekileyo. Kungenxa yeemeko ezinjalo ezicatshangelwayo i-cryopreservation yamaqanda. Le iteknoloji ikwandisa amathuba okuba nomntwana onempilo kwiminyaka emva. Kwaye xa kuqhutyelwa i- IVF cryopreservation sele sele yinto eqhelekileyo kunye neqhelekileyo.
Yintoni i-cryopreservation?
I-cryopreservation yeqanda yinkqubo yokugcinwa kwayo kwifom efriziwe, ngokubuyiselwa kwemisebenzi emva kokuphazamiseka. Ngaphambili, i-cryoconservation yeeseli zesini zesini yayingenakulinganiswa, kuba isetyenziselwa indlela yokucotha. Kwakunzima kakhulu ukuba ungalonakalisi isakhiwo se membrane ngenxa ye-crystallization ngexesha lokupholisa. Ngenxa yoko, ezininzi iiseli zazingenakwenzeka emva kokunyuka kwe-cryopreservation-thawing.
Indlela yokwenza i-vitrification iqaliswa ngokutsha kwe-oyoytes (iiseli zesini). Ndiyabulela ngale ndlela, iqanda likhutshwe ngokukhawuleza, ligqithise isigaba sokwakhiwa kwamakhristal, okonakalisa isakhiwo salo. Ukusinda kwamaqanda kunye nokupholisa kunyuke ngokuphawulekayo. Yintoni eyenza i-vitrification inetyenzi elithembisayo kwinkqubo yeyeza lokuzala.
Iinjongo zokunyuka kwamaqanda kwi-cryopreservation
Ukuchithwa kwamaqanda kunamaxabiso amaninzi kwimeko yokuziphatha kunye nemvelo:
- Ibhinqa liyakwazi ukumisa amaqanda alo amancinci, aze abele umntwana kumdala okhulileyo. Sinokuthi ii-ovules zilahlekelwa ngumgangatho wazo kwiminyaka. Kwaye kwiminyaka engama-20, umfazi unakho amathuba okubeletha umntwana ophilileyo, ngaphezu kwe-35-40.
- Kukhona i-oocytes enobuncitshisiweyo ngenxa yezizathu zonyango. Ngokomzekelo, i-oncology ngaphambi kwekhemotherapy, abafazi abaphethwe yi-endometriosis (isifo esibangela ukungasebenzi kwe-ovarian).
- Kuyinto engqiqweni ukusebenzisa loo friji kumjikelezo we-IVF. Emva kokuvuselela i-ovulation, ibhinqa lingakhula kumaqanda ama-15, ngelixa iimbumba ezimbini kuphela zingeniswa kwisibeleko. Bonke abanye basenokushiywa xa kusweleka okanye xa kukho umnqweno wokuzala omnye umntwana. Ukuchithwa kweqanda kuya kubiza imali encinci kwaye ikhuselekileyo kumfazi kunokuqala ukuqhuba inkqubo yokuvuselela, ukugqithisa nokunye.
- Ngenxa yezizathu zokuziphatha, ukuqanda iqanda kukubhetele kunokugqithisa i- embropreservation ye-embryysi egqityiweyo . Ngenxa yokuba ekupheleni kwexesha kubomi babantu, ubuninzi buyatshintsha. Abatshatileyo banokuthi bahlule okanye kusekho izizathu ezininzi zokuba iibhebri zihlala zingabizwa ngabazali bazo. Oku kubandakanya iingxaki ezininzi kwiziko lezonyango, apho iimbumba ezincinci zigcinwa khona, njengoko umthetho wanamhlanje awunikezeli ngeemeko ezinjalo.
Ngokubhekiselele kuzo zonke ezi ngasentla, kunokugqitywa ukuba ukunyuswa kweeqanda kukunyathelo oluqhubekayo kwicandelo lokuzala. I-Vitrification yeeseli yenza ukuba kubekho abafazi be-oncological ukufumana uvuyo lobazali. Eli lilungelo elihle lamabini abantwana abangabantwana abangabantwana bodwa. Kwakhona, abafazi abangashadile banike ithemba kwixesha elizayo ukuba babe ngumama wengane ephilileyo.
Ngokwezibalo, abantwana abazalwe ngoncedo lwe-cryotechnology abafani nabo bazalwa ngendlela eqhelekileyo, yendalo. I-Frost ayinyuli umngcipheko wokwakha i-pathologies ye-congenital. Ngokuphambene noko, sinokukubona ukutyekela kokukhetha okwenyama, kuba emva kokunyanzeliswa kwe-oocytes efanelekileyo yokuphila.
