Vitotrification ya oocyte - ndi chiyani?

Kawirikawiri, panthawi ya IVF, amayi amtsogolo amakumana ndi mawu akuti "vitrification oocyte", koma nthawi zambiri, iwo sadziwa. Tiyeni tiyankhule za mtunduwu wachinyengo mwatsatanetsatane ndipo talingalirani zizindikiro zazikulu za ntchito yake.

Kodi vitrification ndi chiyani?

Njira yatsopanoyi ikufanana kwambiri ndi kusungunuka, komwe kumazizira ma maselo a kugonana. Zofunikira pa izi zikuchitika, makamaka, pa IVF, pamene kukwera koyamba kumatha. Kuti musasankhenso oocytes, gwiritsani ntchito mavitamini. Onani kuti ma oocyte ndi ovules omwe amakhala m'mimba mwake.

Njira yaikulu yopangira njirayi ndi yakuti, poyerekezera ndi cryopreservation, vitrification imapereka nthawi yochuluka yosunga maselo a kugonana popanda kuchepetsa kupambana kwawo. Kuonjezera apo, njirayi imachepetsanso mwayi wa oocyte kuwonongeka kwa nthawi yozizira, ndipo panthawi imodzimodziyo, kupindula kwa mapulogalamu osokoneza ubongo sikungachepetse.

Monga tanenera kale, njirayi imagwiritsidwa ntchito makamaka mu njira za mu vitro feteleza. Monga lamulo, iwo amagwiritsa ntchito pamene:

• Kulephera kupeza spermatozoa mwachindunji pa tsiku loperekedwa pa IVF;
• Zosatheka kukonzekera mimba posachedwapa (ngati pali zosiyana zokhudzana ndi kubereka kapena kusakhala ndi chilakolako mwa mkazi mwiniwake, mwachitsanzo);
• pamaso chemotherapy kwa amayi omwe ali ndi khansara (kuti asatengere mankhwala a chemotherapy pa maselo a kugonana);
• Kufunika kosunga maoocyte awo atatha kupuma.

Kodi ubwino wa njira iyi ndi uti?

Pamene mavitamini a oocyte, ma oocyte, amatha kuzimitsa nthawi yochepa. Chifukwa cha nkhonoyi, makina osungunuka a madzi oundana, omwe angathe kuwononga chipolopolo cha oocyte, alibe nthawi yokha. Choncho, atatha kuyamwa, madokotala akhoza kukwera mpaka 98 peresenti ya majeremusi azimayi othandiza. Ndiyenela kudziŵa kuti ndi kupopera, kupitirira 60% kupulumuka.

Pogwiritsa ntchito njirayi, kafukufuku wasonyeza kuti ma oocyte osasakanizidwa amamera mofanana ndi maselo omwe ali mu thupi lachikazi. Pochita cryopreservation, pali chodabwitsa choterechi ngati kuchuluka kwa mazira a oocyte. Mfundo iyi imapangitsa kuti umuna ufike mkati mwa dzira.

Kodi maonekedwe a vitrification ndi ati?

Pasanapite nthawi yochepa kuti chiberekero chiyambike mu thupi lachikazi, mankhwala apadera a mahomoni amachitidwa kuti apangitse mazira. Nthawi yomweyo asanatulutse ovum kuchokera ku follicle, ultrasound amapatsidwa. Izi zimapangitsa kuti atha kukhala ndi mazira okhwima. Ngati sapezeka - njira yolimbikitsa imabwerezedwa kachiwiri. Ngati dzira lili loyenera kumera, ndiye kuti mphuno imapangidwa (mpanda wake).

Ndondomekoyi imachitidwa pansi pa anesthesia. Pa nthawi yomweyi, kufikako kumachitika mopyolera, pogwiritsa ntchito singano yapadera. Njirayi imayendetsedwa ndi zipangizo za ultrasound. Ma oocyte omwe amasonkhanitsidwa amakhala oundana ndipo akhoza kusungidwa kwa nthawi yaitali.

Choncho, tinganene kuti kupukuta ndi kutsekemera ndi njira ziwiri zofanana, zomwe zimachitidwa mwanjira yomweyo, koma zimakhala ndi zochitika zawo zokhazokha. Posachedwapa, IVF yokhala ndi vitrification yakhala ikugwiritsidwa ntchito kwambiri, kuphatikizapo cholinga chokhazikitsa mabanki a oocytes m'makliniki ochizira.
