I-vitotrification yama-oocyte - yintoni na?

Ngokuphindaphindiweyo, ngexesha le-IVF, oomama abazayo baya kujongana negama elithi "i-oocyte vitrification", kodwa kwiimeko ezininzi, abayenazi, abazi. Makhe sithethe ngale ndlela yokusetyenziswa ngokubanzi kwaye sicinge ngeendlela eziphambili zokusetyenziswa kwazo.

Yintoni i-vitrification kwaye isebenziselwa phi?

Le ndlela inokugqithisileyo ifana kakhulu ne-cryopreservation, apho kufakwe isithwathwa seeseli zesini zesini. Kubalulekile kule nto ivela, ikakhulukazi, ngexesha le-IVF, xa ukufika kokuqala kungaphumeleli. Ukuze ungaphinda ukhethe i-oocytes, sebenzisa ngokuqinisekileyo. Qaphela ukuba ii-oocytes zi-ovules ezincinci zifumaneka ngqo kwiiyunithi.

Inzuzo ebalulekileyo yale nqubo kukuba, xa kuthelekiswa ne- cryopreservation, i- vitrification ivumela ixesha elide ukugcina iseli zesini ngaphandle kokunciphisa ukusebenza kwazo. Ukongezelela, le ndlela iyancipha ukunciphisa umonakalo we-oocyte ngexesha lokuqhwabalalisa, kwaye ngexesha elifanayo, ukuphumelela kweenkqubo zokusasaza iindawo ezingenziwanga ziyancipha.

Njengoko sele kukhankanywe ngasentla, le ndlela isetyenziselwa ngokuyinhloko kwiinkqubo zokukhutshwa kwe-vitro fertilizer. Njengomthetho, bathelela kuyo xa:

• ukuba akunakwenzeka ukufumana i-spermatozoa ngokuthe ngqo ngomhla wokugqitywa ngexesha le-IVF;
• akunakwenzeka ukucwangcisa ukukhulelwa kwixesha elisondeleyo (ukuba kukho ukuchasene kwindlela yokuzala okanye ukungabikho komnqweno kumfazi ngokwawo, umzekelo);
• phambi kwe-chemotherapy kwabasetyhini abanomdlavuza (ukuba bangabandakanyi impembelelo yekhemotherapy kwiisini zesini);
• Isidingo sokugcina ii-oocytes zabo emva kokugqitywa.

Ziziphi iingenelo zale ndlela?

Xa i-oocytes ekhulile, i-oocytes, i-oocytes, i-oocyte, i-oocyte, inkqubo yokhenkcela iyenzeka ngexesha elifutshane. Ngenxa yobu bunzima, i-crystals e-microscopic ice, engonakalisa iigobolondo ze-oocyte, akanayo ixesha lokwenza. Ngaloo ndlela, emva kokuthabatha, oogqirha banokunyuka ukuya kuma-98% eeseli zentsholongwane zentsholongwane. Kubalulekile ukuba uqaphele ukuba nge-cryopreservation, akukho ngaphezu kwama-60% okusinda.

Eqhutywe ngempumelelo kule ndlela, uphando lubonise ukuba ii-oocytes ezingenasiphelo zixutywa kunye neemeko ezifanayo njengaleli maseli asemzimbeni wesifazana. Xa kuqhutyelwa i-cryopreservation, kukho into efana nokuxinwa kweembumba ze-oocyte. Le nyaniso iyanzima kakhulu ukungena kwesidoda kwiqanda.

Ziziphi iimpawu zobungqina?

Kungekudala ngaphambi kokuqala kwe-ovulation kumzimba wesetyhini, unyango olulodwa lwe-hormonal lungenziwa ukuze kukhuthazwe ama-ovari. Ngokukhawuleza ngaphambi kokukhululwa kwe-ovum evela kwintolthi, i-ultrasound inikezelwe. Oku kwenza ukuba kwenzeke ukuba amaqanda avuthiweyo afanelekileyo. Ukuba afunyanwanga - inkqubo yokuvuselela iphinda iphindwe kwakhona. Ukuba iqanda lilungele ukuchumisa, ukugqithiswa kwenziwa (ucingo lwayo).

Inkqubo yenziwa phantsi kwe-anesthesia jikelele. Ngethuba elifanayo, ukufikelela kufakwa ngokukhawuleza, usebenzisa inaliti ekhethekileyo. Inkqubo ilawulwa zixhobo ze-ultrasound. I-oocytes eqokelelweyo ikhuni kwaye ingagcinwa ixesha elide.

Ngaloo ndlela, kungatsholwa ukuba i-cryopreservation kunye ne-vitrification ziindlela ezimbini ezifanayo, zenziwa ngendlela efanayo, kodwa zineziganeko ezizimeleyo zokwenza. Kungekudala, ii-IVF kunye ne-vitrification zisetyenziswe ngokubanzi, kubandakanywa nenjongo yokudala ibhanki yama-oocytes kwiiklinikhi zonyango zokuzala.
