Mishonga inobereka irikudzika pamutengo unoshamisa, uye iye zvino vakawanda vakaroorana avo vangadai vakagamuchira mutemo we "kusununguka" vane mukana wekuva vabereki. Kugadzirwa kwepermu ndeimwe yekubudirira kwakadaro kunowanzoshandiswa pakubatsiridza kubereka vana (ART). Tichazivana nezviratidzo zvegyopreservation yembeu uye zvinyanzwisisika zvekombiyuta.
Chii chinokonzera kufungidzira kwemuviri?
Pane huwandu hwezviratidzo, maererano nezvinodiwa kuti spermplicationzo ye spermatozoa iite, inosanganisira:
- kuumba mbeu yebhuruki;
- munyaya iyo isingakwanisi kuwana spermatozoa yemurume yekugadziriswa kwemafuro pazuva rekutsvaira kwehupenzi mukadzi;
- kana zvakakosha kuwana hutano hwakakwana hwepamusoro-grade spermatozoa nehuwandu hwakakwana mu ejaculate (oligozoospermia).
Kusunungura mbeu uye mazai inhanho huru mukurapa kwekubereka. Iyi nzira ine tsananguro kana spermatozoa ichibviswa chirwere kuti isadzivirirwa kuunganidza zvakare mbeu. Mukuwedzera, kunyange munhu akazara-akazara haasisina zvirwere nekukuvadzwa zvinogona kuderedza kukwanisa kwemunhu kubata kana, kazhinji, kusazviisa. Uye kufungira hupenyu hwake, murume ane mukana chaiwo wekuva baba.
Kugadzirira kubwinyorwa kwehuta
Usati wavhenekera mbeu yako, murume anofanira kuongororwa. Saka, zvakakosha kuongororwa ndezvi:
- kuongororwa kwechirphilis, hutachiona hwehutachiona hwehutachiona, hepatitis B uye C;
- miedzo yezvirwere zvepabonde.
Zvinokurudzirwa kutakura cryotest, kureva, mushure mokunge ichandova nehutano hwakanaka, husingafadzi humwe hwemunhu anopa ruzivo kuti aongorore hutano hwake mushure mekudzivirira uye nekuita kwepermatozoa.
Nzira yekuunganidza nekuchengetedza mbeu
Kusununguka kwepermatozoa kunosanganisira zvikamu zvakasiyana.
- Saka, danho rekutanga nderokuwana hurasi uye kurichengetedza pamusana wekupisa kwemaawa kusvika kweawa imwe chete, kuitira kuti kuzviparadzanisa kunoitika.
- Muchikamu chechipiri, chishuwo pachako chinogadzirwa nekuwedzera cryoprotectant kune ejaculate, iyo inodzivisa kuparadzwa kwe spermatozoa munguva yehutukuta, kubwinya kwemvura mumasero uye inoita kuti membrane dzese dzisimbiswe.
- Mushure mekuwedzera kwegyoprotectant, iyo yakagadzirwa yakasara yakasara kwemaminetsi gumi nemashanu, mushure mokunge izere nezvakakonzera (cryosolomines). Iyo michina ine mishonga inochengetwa mukamuri inotonhorera chete panzvimbo yakanyanyisa, inofanira kuiswa uye yakavharwa zvakasimba.
Iyo inotonhorera inoitwawo zvishoma nezvishoma kusvika pakushambidzwa kwe -198 ° C (kutonhora kweyero nitrogen). Kudzikisa mbeu inofanira kunge yakangoerekana isati yatanga kuitika mu in vitro fertilization kana insemination.
Ichokwadi, kwete yese spermatozoa kuchengetedza mano avo ekugadzirira panguva yakakodzera,
Saka, maitiro ekudyopreservation yevarume ndeimwe yezvigadzirwa zvekare zvemishonga zvemazuva ano, izvo vakawanda vakaroorana nevarume vechidiki vakapa tariro yekuzvarwa kwomwana. Pfungwa isina kunaka ndiyo yakadhura, sezvo kudiwa kwemidziyo inodhura yekuvhenekera uye kuchengetedza uye kugadzirira zvikuru kunowedzera iyo mumutengo. Uye izvi, zvakare, zvinoita kuti zvive nyore kusvika kune varume vane chiyero uye pasi pevhareji yepamusoro yekubudirira.
