Kupora muviri ndiko kusviba kwemajeri ehurume nevakadzikadzi, pamwe nemabrosi kuitira chinangwa chokudzichengeta kwenguva isingagumi. Uropa, oocytes uye mazai anokwanisa kunamatira kusvika pakusvika -196 degrees Celsius mu nitrogen yemvura.
Pamberi pemvura inotonhora, unyoro hwose hunobviswa pamasero, sezvo hunouraya paunonaya. Chengetai mazaya akaoma muzvivako zvakasiyana-siyana - Dewar midziyo. Zvikamu zvose zvakanyorwa, mazai anochengetwa 1-2 mu vitro.
Chii chinonzi cryopreservation of sperm uye oocytes?
Uhu hunogona kuvharwa kana IVF iri kurongwa, asi pazuva rekuvhara murume uyu haazovi muchechiki pane chimwe chikonzero kana chimwe. Chimwe chinonzi spermogram chimwe chikonzero chekushandura kugadzirwa kwepermatozoa. Izvi zvinoita kuti zviitike mumatanho akawanda kuti atore huwandu hwemhando yehuta uye kubudirire kuita purogiramu ye in vitro fertilization.
Evha inogona kuve yakanyungudzwa kune avo vane chirwere chekudya. Pamberi pemayera uye chemotherapy, iyo inonyanya kutungamirira pakurasikirwa kwekuberekwa kwevakadzi , unogona kugadzira mazai kuitira kuti mune ramangwana awane vana.
Semheni yakasviba
Akaunganidzirwa kuvhenekera chirwere chemuviri. Inotarisana nemuedzo unotonhora uye unopesana. Kana zvikwangwani zvakanaka, uye kuedza kwekuti kana zvichikwanisa kuvhara mbeu yakabudirira, zvinyorwa zvitsva zvinounganidza zvinowedzera uye zvinowedzera kuongororwa, kushandiswa zvakanaka uye kuiswa mumudziyo. Iyo nhumbi isimbi yepurasitiki yepurasiti yemaduku. Iyi tubhusi inonyorwa kuitira kuti isasakanganiswa kana yakasanganiswa nemuna yakaoma.
Kugadzirwa kweoocytes
Kuunganidzwa kwamazai kunotonhora ndeyeiyo yakareba uye yakaoma zvikuru kudarika mbeu. Mukadzi anopiwa mahomoni ekusimudzira mavhai kuitira kuti maoocyte akawanda ave nekukura panguva imwechete. Mushure meizvi, pane kuvhara mazai, kusarudzwa kweiyo inogona kushandiswa. Vanoshandiswa uye mvura yakawandisa inobviswa, ndokuiswa mune imwe chigadziko chakasviba uye mazaya ane nitrogen yemvura.
Cryopreservation of embryos
Embryos yakanatswa nokuda kwezvinangwa zvakasiyana. Pakutanga, kuitira kuti, kana pane imwe nzira isingabudiriri, IVF inogona kuedzwazve pasina kudzokororazve mazai uye kupora maoocyte.
Mukuwedzera, embryo inowanikwa mumagariro apo mukadzi asingabvumiri kutumirwa kwemazamu (ovarian hyperstimulation syndrome). Kusagadzikana kwe endometrium ndechimwe chikonzero chekuvhenekera mazamu. Embryos munyaya iyi inova nemazuva mashoma, saka zvakanakisisa zvezvo zvinosarudzwa uye zvinokwanisa kubhadhara. Apo endometrium yemukadzi iyi yakagadzirira mazai, kutumirwa kwemazai echando kunoitika.
Frozen embryo inochengetwa chero bedzi iwe uchida. Zvechokwadi, kushandiswa kwemhepo kunopisa uye kunopisa kunokonzera kushungurudzika kwemazai. Asi nzira dzemazuva ano dzinobvumira kwete chete kuponesa nhamba yakakura yemashizha echando muhurumende yakasimba, asiwo kuvimbisa kuti ivo vanowanzoita
Mamiriro ezvinhu e-cryopreservation of embryos
Kutanga, ndiyo chete mazai anonyanya kukosha anobvumira chishu - nehupamhi hwehutano huno. Chechipiri, inoitika pane imwe nzvimbo yekukura kwavo: mumitezo 2, 4, 8 masero uye blastocysts.
Embryos, ane zviratidzo zvinorondedzerwa sevakaipa, hazvikweretesi kubheta, sezvo vane pfuma yekunyadzisa-kuputsa. Dzimwe nguva mazai akanaka akaparadzwawo - iyi ndiyo mutengo wekuvhunduka kwavo uye kupedzisira kunotevera. Asi pane nguva dzose mazamu mazamu akawanda, saka vamwe vavo vanoramba vachigadzikana mushure mokunge vachinya.
