Kurwiswa kwembryos ndiyo nzira inovabvumira kuti varambe vakagoneka kwemakore anoverengeka nekodzero yakachengetedzeka yekuparadzanisa mushure mekunyangarika. Nzira yegyopreservation inoshandiswa nekurapa mazai nemvura inonzi nitrogen. Muchikamu chino tichakurukura maitiro ehutambo hwemhepo, mavara avo, pamwe chete nehuwandu hwemagyprotective embryos mu uterine cavity munguva in vitro fertilization .
Technology ye embryo inotyisa
Pane maitiro maviri ekuvhenekera mazai: vitrification uye "kunonoka kupisa". Inyanzvi ye "inononoka kupisa" inofungidzirwa isingashandisi uye haina kurega kushandiswa mumakiriniki mazhinji. Inosanganisira kuendesa mazai echando mukati mejecha ine cryoprotectant, iyo inotonhora mvura inobudiswa. Kusunungura embryo kunodzivirira kubva kunezaya, asi kunogona kutungamirira pakupera kwayo. Izvi zvinoderedza nhamba yemambrus iyo isingagoni chete kurarama, asiwo kuchengetedza kukwanisa kugovana uye kusiyanisa.
Vitrification ye embryo ndiyo nzira yemazuva ano, iyo inosanganisira mukubata ne nitrojeni yemvura, asi mvura iyo yavanayo inoshandurwa kuva jelly.
Iyo midziyo yegyopreservation inodhura zvikuru, kunyanya iyo inoshandiswa "kunonoka kupisa". Irofu-hupenyu hwemazamu echando haufaniri kudarika makore mashanu.
Kudhindwa kwemazai mushure mekunyorwa kwegoropreservation
Iyo embryo, iyo yakabva kunotonhora isati yaiswa mumuviri, inofanira kugadzirirwa. Kuti vaite izvi, vanodonhedzwa mumhepo yechando uye vanorapwa nechinangwa chaicho chichabatsira embryo kuchengetedza zvayo. Kuendeswa kwemasvosve akabatwa kunowanikwa kuburikidza nekateti inokosha, iyo inowanikwa kuburikidza nemugero wechiberekero mukati mehutachi uterine.
Takabvunzurudza maitiro ehutachiona embryo echando, uyewo nzira yekugadzirisa mazai akaomeswa. Kurwiswa kwemazamu kunoita kuti zvive nyore kuisa zvakare kana pasina kutora mushure mekutanga.
