Yuav ua li cas yog hom txheej txheem no?
Ntev ntev embryo cultivation yog inherently high-tech thiab theej complicated txheej txheem uas yuav tsum tau muaj kev tshwj xeeb, zoo nrug laboratory thiab khoom kim heev. Nws yog nyob rau hauv view ntawm no feature hais tias tsis yog txhua cov chaw muab kev koom tes nyob rau hauv IVF thiab cev xeeb tub npaj muab xws li ib tug txheej txheem.

Qhov no qhov tseeb yuav txo cov kev vam meej ntawm IVF thiab cov txheej txheem rau embryo hloov tau ua dua ntau zaus.
Cov kev hloov mus rau cultivation ntawm embryos nyob rau hauv vitro tau ua tau rau ib tug kev kov ub no nyob rau hauv lub tshav pob ntawm embryology, ua tsaug rau tshwj xeeb tsim nyob rau hauv lub tshav pob ntawm cov tshuaj kho me nyuam. Hom no, siv rau cov chaw kho mob loj hauv lub ntiaj teb no, yog kev sib txuas ntev nrog lub embryo ntawm tej qhov chaw kawm tshwj xeeb (SICM / SIBM thiab Embryo Assist / Blast Assist).
Nws kuj yog tsim nyog sau cia tias cov txheej txheem no yuav tsis muaj nyob yam tsis tau siv ib qho khoom tshwj xeeb - ib lub tshuab siv roj ntau. Nws yog nyob rau hauv nws hais tias ntau zygotes yog muab tso nrog rau qhov nruab nrab cev. Tom qab 4-6 hnub, cov kws kho mob tshwj xeeb muab cov blastocyst los ntawm tus ntaus ntawv no thiab ntsuam xyuas nws qhov kev pom zoo.

Tsis tas li ntawd, cov lwm yam zoo ntawm cov sij hawm ntev embriyo cultivation yog feem ntau hu ua:
- txo cov chromosomal abnormalities hauv embryos transplanted hauv cov blastocyst theem;
- qhov no yog ntau yam muaj sia nyob rau hauv kev sib piv nrog embryo hloov mus txog 3 hnub;
- ntawm ntev cultivation nws yog txaus tso 1-2 embryos nyob rau hauv ib tug kab noj ntawm ib lub tsev menyuam, tk. qhov tshwm sim ntawm lawv cov kev lag luam thiab kev loj hlob yog siab;
- qhov kev pheej hmoo ntawm kev tsim muaj qhov teebmeem no yog ib txoj kev xeeb menyuam ectopic ho txo.
Dab tsi yog qhov tsis zoo ntawm txoj kev no?
Muaj kev nkag siab tias qhov no yog kev cog qoob loo ntawm gametes thiab embryos, muaj qhia txog qhov zoo ntawm hom no ntawm IVF, nws tseem ceeb heev kom tsis txhob hnov qab txog cov kev tsis txaus siab ntawm hom no.
Thawj ntawm cov no yog qhov tseeb tias tsis tag nrho cov embryos loj hlob mus rau blastocyst, feem ntau tsuas yog 50% ntawm lawv mus txog theem no ntawm kev loj hlob. Ua li no, qhov no yog ua tau yog thaum hnub thib ntawm kev cog qoob loo, muaj nyob qis tsawg kawg 4. Thaum qis dua, qhov yuav tau txais tsawg kawg yog ib qhov qub, ncav cuag theem ntawm blastocyst, yog qhov tsawg heev.
Qhov thib ob tsis zoo yuav raug hu ua lub sij hawm ntawd txawm tias lub embryo mus txog theem ntawm kev tsim nyog rau kev sib hloov, qhov no tsis muab 100% lav tias lub implantation yuav muaj kev vam meej thiab lub cev xeeb tub yuav tuaj.
