Nhasi, vakadzi vanowanzova nekuberekwa kwekupedzisira. Nokuda kwechimwe chikonzero, mukadzi anoedza kubvisa pamuviri nekuberekwa. Kazhinji kazhinji izvi zvinokonzerwa nechido chekuwana rusununguko rwezvemari, kukwira basa rekushanda, kana kungoita kusava newawakaroorana naye. Izvo ndezviitiko zvakadai kuti cryopreservation mazai inofungidzirwa. Iyi teknolojia inowedzera mikana yekuva nehutano hwakanaka pane imwe nguva. Uye kana kuita IVF cryopreservation kwave kwatova tsika yakajairika uye yakajairika.
Chii chinonzi cryopreservation?
Kubvongodzwa kweii ndiyo nzira yekuchengetedzwa kwayo mufomu yakaoma, pamwe nekudzorerwa kwebasa mushure mekudzikisa. Pamberi pekare, kubvongodzwa kwemasero evanhukadzi zvepabonde kwakanga kusingagoneki, sezvo nzira inononoka kupisa yakashandiswa. Zvakanga zvakaoma zvikuru kuti zvisakanganise chimiro chemuviri nekuda kwekristallisation munguva yekugadzirisa. Somugumisiro, masero akawanda haana kushandiswa mushure mekunyora-kutengesa-kutora.
Nzira ye vitrification ikozvino iri kubudiswa nokuda kwegyopreservation ye oocytes (masero emagetsi). Kuvonga nenzira iyi, zamai yakanyanyiswa zvakanyatsokurumidza, ichipfuura nepakati penzvimbo yekuumbwa kwemakristasi, ayo akaparadza maitiro ayo. Kupona mazai nekunakisa uku kwakawedzera zvinoshamisa. Chii chinoita kuti vitrification ishandise nzira inovimbisa mubasa rekurapa.
Makomborero e-cryopreservation mazai
Kugadzirwa kwe mazai kune zvakakosha zvakasiyana zvose zvehutsika uye hwepanyama:
- Mukadzi anogona kuvhara mazai ake madiki, uye kubereka mwana pane imwe nguva yakakura. Tinogona kutaura kuti ovules inorasikirwa nehuhu hwavo pamakore. Uye pamakore makumi maviri, mukadzi ane mikana yakawanda yekubereka mwana ane utano, kupfuura muna 35-40.
- Pane pfungwa yeoocyte yakakonzerwa nokuda kwechikonzero chekurapa. Somuenzaniso, oncology vasati vasvika chemotherapy, vakadzi vane chirwere chinonzi endometriosis (chirwere chinokonzera ovarian kudzvinyirira).
- Izvo zvine musoro kushandisa shanduro yakadai mumhepo yeVIV. Mushure mekusimudzira kuvhuvhuta, mukadzi anogona kukura kusvika mazai gumi nemashanu, asi mazamu maviri chete anogona kuiswa muchibereko. Vamwe vose vanogona kusara kana paine kupererwa kana kana pane chido chokubereka mumwe mwana. Kugadzirwa kweii kuchasvitsa mari shoma uye yakachengeteka kumudzimai kupfuura itsva kutevedzera nzira yekukurudzira, kuputika nezvimwe zvakadaro.
- Pamusana pezvikonzero zvetsika, mazai echando ari nani kudarika kupera kwekushandiswa kwemamota . Nokuda kwekuti pakuguma kwemazuva muupenyu hwevanhu, zvakawanda zviri kuchinja. Vakaroorana vanogona kugovera kana kuti kune zvimwe zvikonzero zvakawanda nei mazai akaramba asina kubvumirwa nevana vavo vane mazita. Izvi zvinosanganisira zvinetso zvakawanda zvechiremba, apo mazai akaomeswa akachengeterwa, sezvo mitemo yemazuva ano isati yatarisa mamiriro akadaro.
Maererano nezvose zviri pamusoro apa, zvinogona kugumiswa kuti kubvongodzwa kwamazai inzira inofambira mberi mune zvekubereka. Vitrification yemasero inoita kuti zvive nyore kune vakadzi vepachikoro kuti vawane mufaro wevana. Uyu ndiwo mukana wakanaka kwazvo wemhuri isina vana kuti vave vabereki vasina kunyange mwana mumwechete. Uyewo, vakadzi vasina kuroora vanopa tariro mune ramangwana kuti vave amai vemwana ane utano.
Maererano nehuwandu, vana vakaberekerwa nekubatsirwa kwekrisotechnology havakisi kune avo vakagadzirirwa mumutambo, kazhinji. Frost haiti kuwedzera kungozi yekukura kwepenital pathologies. Pane zvakasiyana, tinogona kuona kutama kwekusarudzwa kwezvisikwa, sezvo mushure mekugadzirisa-kunyura kwehutano chete maoocyte anowirirana anoramba aripo.
