Vitrification ya mazira a maselo

Kwa IVF ( mu vitro feteleza ), nthawi zambiri pamafunika kusunga majeremusi kapena mazira. Pali mitundu iwiri ikuluikulu yowonongeka kwa mazira: kuchedwa kozizira ndi mavitri.

Mitundu yowonongeka kwa mazira

Kulowera kozizira ndi njira yowonjezereka, yomwe njira yamadzi yozizira kuyambira mwana wosabadwa akugwiritsa ntchito nayitrogeni yamadzigwiritsidwe ntchito. M'mimbayi ndi makina opanga mavitamini (kutetezera ku kuwonongeka kwa chimfine) amaikidwa musupa wa pulasitiki ndi utakhazikika mpaka madigiri 0,5 pamphindi mpaka madigiri -7. Kenaka amakhudza udzuwo ndi timadzi tawiri tomwe timadziziritsa mu nayitrojeni yamadzimadzi (kuzizira madzi kuchokera m'mimba), ozizira pang'onopang'ono mpaka madigiri 35, kenako amasamukira ku nayitrojeni yamadzi ndi kutentha kwathunthu mpaka madigiri -196.

Kuipa kwa njirayo mwa njira yokhayo, kuti, kutaya thupi kwa madzi kumathandiza kupulumuka kamwana kamene kamakhala kozizira, ndipo kumbali ina ikhoza kuipasula kwenikweni chifukwa cha kuchepa kwa madzi - madzi okhudzana ndi mapuloteni amachokeranso thupi, lomwe limawononga maselo.

Njira yamakono ndiyo vitrification ya mazira. Panthaŵi imodzimodziyo, kuzizira kochepa kumachotsedwa ndi kupanga makina osungunula. Udzu wopangidwa ndi pulasitiki wokhala wodalirika komanso wovuta kwambiri wopanga makina opanga mavitamini nthawi yomweyo umayikidwa mu madzi a nayitrogeni, pogwiritsa ntchito kusinthika kwa madzi onse kupita ku vitreous state. Ndi njira iyi, palibe kutaya madzi kwa mimba ndipo imalekerera mosavuta popanda kusokoneza.

Pang'ono ndi pang'ono, mazira amatha kukhala 25 mpaka 65%, ndipo ngati vitrification - 10-12%. Mu nayitrogeni yamadzi, mazira akhoza kusungidwa kwa zaka 12. Mazira obiriwira si nthawi zonse oyenera: Nthawi zambiri amamera mazira angapo, koma mazira oposa 2-3 amaikidwa mu chiberekero cha kuikidwa. Koma mazira a mazira angagwiritsidwe ntchito nthawi, osati nthawi zonse pambuyo poti mimba ya IVF imabwera nthawi yomweyo, ndipo mazira amapepala amafunika kuti ayesedwe. Ngati mimba yayamba, ndiye kuti chilolezo cha mazira azirazi chikhoza kuwonongedwa.

Vitrification wa mazira ndi spermatozoa

Kuwonjezera pa mazira ozirazira, pangakhale kofunikira kufungira ndi majeremusi. Vitrification ya umuna zingakhale zofunikira pamaso pa opaleshoni munthu, pambuyo pake mphamvu yake ya manyowa ingachepe. Pamaso pa kuzizira, umuna umayang'aniridwa ndipo umodzi wokha umagwiritsidwa ntchito womwe uli ndi spermatozoa ndi kuyenda bwino komanso popanda kuwonongeka.
