Muchiitiko chekuti vaviri vakaroorana vanoda kuva nechivimbo chakakwana mukuzvarwa kwevana vane utano uye vakakwana, zvakakosha kuti tive nehanya nekuita maitiro ekuberekwa panguva yekuzvitakura. Zvechokwadi, iyo yakanakisisa inosarudzwa ichave iyo yekushandiswa pachikamu chekugadzirira kubata uye kuberekwa kwechecheche, asi kazhinji, vanhu vanoziva kuti vachakurumidza kuva vabereki, zvisingatarisirwi.
Mune zviitiko zvipi zvakakosha kuwana migumisiro yezvidzidzo zvemuviri panguva yekuzvitakura?
Kana amai vane ramangwana vawira mu "boka rekutengesa", saka zvinomiririra kuti ave nechekuongorora ne geneticist. Kunyanya kukosha ndeyokuberekwa kweiyo genetic kuongorora ropa panguva yekuzvitakura mumamiriro ezvinhu akadai se:
- zera remangwana rakamhanya kupfuura makore makumi matatu;
- mumutambo wemwana ane pamuviri, kuberekwa nehutano husina kunaka kana zvirwere zvekuzvarwa zvakatoitika;
- Maitiro ekudzivirira panguva yekuzvitakura inofanirwawo apo mukadzi, nguva pfupi vasati vasangana, vakashandisa zvinodhaka, doro, kusvuta kana kubatwa nemishonga yakasimba;
- zviratidzo zvekutsvakurudza uku zvichave zvisati zvaitika, kusarudzwa kwemutoro wemwana akafa kana mwana ane zvirwere.
Usarega kuongorora kuwanikwa kwemajini mumadzimai ane pamuviri, kana amai vanguva yemberi vaifanira kurwara nehosha yakasimba kana zvirwere zvinotapukira.
Mhando dzakasiyana-siyana dzezvechimiro chevakadzi vanozvitakura
Nzira dzinowanzoshandiswa yekucherechedza maitiro ekusafukidzira ndeyekuongorora kwehupenyu hwekuongorora ropa uye ultrasound. Kana vakaratidza kuvapo kwehupi hupi hwehutachiona, mukadzi wacho achada kuita zvinyorwa zvose zveongororo, zvakadai sokuti: sampuli uye kuongorora placenta particles uye fetal outer shell ( chorionic biopsy ), amniotic fluid tsvakurudzo, cordocentesis nezvimwe zvakawanda. Asi kunyange vose havangagoni kupa mufananidzo wakakwana, sezvo kubata kwega kwega kune imwe nzira uye yakasiyana.
