Chii chinonzi cryoconservation of oocytes?
Iyi nzira inofungidzirwa sechimiro chekombiyuta yekuongorora. Chinhu chacho ndechekuti kazhinji kana ichiitwa, kuperesa kwemaoocyte mushure mokunge shumba ichinge yakaderera. Mukuwedzera, masero ehupombwe, mushure mekutsvaira uye kuisa pahuwandu hwemutambo, haigoni kugara uchigadzirwa.
Kubudirira kwemuitiro uyu kunogona kururamiswa bedzi kana mukadzi asina unhu hwepabonde kana asati agadzirira kuva amai. Mumamiriro ezvinhu akafanana, iyi ndiyo imwe nguva yega yekuva nepamuviri uye kuva nemwana. Sezvo zvinoshandiswa kupisa maoocyte, cryoprotectants dzakadai se ethylene glycol uye dimethylsulfoxide inogona kuita. Kugadzirwa kweiyo mazai kunogona kuitwawo nenzira yakafanana . Inofanira kuonekwa kuti nguva yekuchengetedza haigoni kuponesa nenzira ipi zvayo.
Chinhu chose chinobva pane izvo zvinonzi chimiro chakaoma maoocytes. Saka, musati maita nzira yakadaro, kusarudzwa kunokosha kune kusarura kwakanyatsonaka, kunoitwa nekuongorora maoocyte mune microscope inokosha.
Maererano nenhamba yekucherechedza, kuponeswa kwemaoocyte akaomeswa inenge 68%, nepo kuwandisa kwemafuro avo kune 48%. Kana tikataura pamusoro pekuwanda kwekucherechedza kuberekwa kweoocyte yega yega, izvi zvakaonekwa mune 2% yematambudziko.
Chii chinonzi cryopreservation of the embryo?
Izvi zvinoshandiswa pakukanganiswa kwezvinhu zvinokonzerwa neAVF. Chinhu chacho ndechokuti mazai ekudzvora mavara anopa zviri nani zvikuru.
Kushandiswa kwegadziriro iyi kunobvumira in vitro fertilization nzira kuti iitwe mune imwe chete. Saka, pane imwe nguva apo mushure mekugadziriswa kwemuviri wakakonzerwa nepamuviri, haukwanise kushandisa cryopreserved, uye usasimudzira zvitsva pamutsetse wemuviri.
- kuderedza nguva uye mari yezvinhu zveVIV (utachiona hwemutengo inodhura);
- kuderedza kwenguva yekutongwa;
- mukana wekudzokorora IVF mushure menguva refu.
Izvo zvipingamupinyi zvikuru zvemuitiro uyu zvinosanganisira chokwadi chokuti mikana yekuita pamuviri inenge 60%, uye kuponeswa kwemazai mushure mekunyangarika kwavo kune huwandu hwakawanda hwekuvhara, kubva pa35 kusvika ku90%. Zvichipa zvikonzero izvi, zvakaoma kufanotaura kuti mazai achaiswa sei mushure mekunyorwa kwegorofreservation.
