Thaum twg nws thiaj li tsim nyog rau khov embryos?
Nws yuav tsum tau sau tseg tias cryopreservation tuaj yeem nqa tawm ntawm txhua theem ntawm txoj kev loj hlob (cov suab paj nruas, crushing embryo, blastocyst). Vim hais tias cov txheej txheem yuav siv tau rau txhua lub sijhawm, thaum muaj qhov tsis zoo ntawm kev ua tsis tiav ntawm kev tsaws hauv tsev menyuam.
Raws li kev pab cuam tam sim ntawm khov, cov no yuav tsum raug hu ua:
- Ua rau muaj qhov tsis zoo ntawm kev xeeb tub tom qab IVF thiab kev tiv thaiv ntawm kev tuag ntawm lub cev tsis tuaj yeem embryos, uas ua rau nws siv tau tom qab hauv vitro fertilization.
- Nws tiv thaiv qhov teebmeem ntawm kev siab hlob nyob rau hauv lub xub ntiag ntawm ib tug high school ntau yam ntawm nws txoj kev loj hlob.
- Nws yog ib qho kev daws rau qhov teeb meem nyob rau hauv uas lub synchronization ntawm lub coj mus ncig ntawm pub dawb thiab tus neeg txais yuav tsis yooj yim sua.
Lub cryopreservation ntawm embryos los ntawm vitrification txoj kev yog Individual thaum:
- txo qis dua ntawm qhov kev muaj peev xwm ntawm implantation nyob rau hauv lub uterine kab noj hniav, nyob rau hauv view ntawm muaj mob nyob rau hauv qhov kev ua me nyuam yug (polyps, piv txwv li);
stenosis ntawm lub ncauj tsev menyuam hauv caws pliav (tsis muaj catheter mus rau ntawm lub ncauj tsev menyuam hauv kwj dej).
Li cas khov rau cov embryo?
Nyob rau hauv cov chav kawm ntawm ntau cov kev tshawb fawb experimental, nws pom tau tias nqa tawm no txoj kev ua tau zoo tsis effect rau ntxiv kev loj hlob ntawm lub embryo. Yog li, yog hais tias, tsim nyog, cov biomaterial yog muab rho tawm los ntawm cov tshuaj ntsiav nrog kua nitrogen, sab laug ntawm qhov ntsuas kub ntawm 20-22 degrees, tom qab uas lub tshuab cryoprotectant muab tshem tawm thiab lub embryo tso rau hauv ib qho tshwj xeeb nruab nrab. Tom qab ntsuam xyuas qhov kev mob ntawm lub embryo, pib mus rau kev cog qoob loo.
