Ukuzalanisa oocytes: izici inqubo yemvelo futhi yokufakelwa

Phambilini, amaqanda avundiswa zihlale nje ngendlela ejwayelekile. Ngenxa yalokho, uma Abantu baligcina ukungavumelani immunological, ithuba yokuzalwa izingane zabo bathambekele zero. Siyabonga ekuthuthukiseni isayensi nobuchwepheshe namuhla has kungenzeka insemination yokufakelwa. Ngezinye izikhathi le ndlela abunakuqhathaniswa ngempela.

kokukhulelwa Yemvelo

Le ndlela is kabanzi izilwane zasendle. Ihlala eqinisweni lokuthi gametes iduna nensikazi bemunye zygote. Ngakho isidoda ahlale yedwa nesidoda okunikelwe, futhi iqanda inikeza, futhi imali eyanele izakhi okuyinto kwanele kuze kube isikhathi lapho umbungu ukwakha unamathele kwesibeletho.

kokukhulelwa Yemvelo - inqubo ukuthi eside kakhulu phelelisa nemvelo. Ngenxa yalokho, namuhla kucishe kube njalo kokubili ngempumelelo kakhulu futhi kubenzima. Lokhu kuholela yokuthi abantu musa njalo uphathe ukuba izingane zabo siqu. Kuleso simo, uma abantu Awunawo zokugula of umthondo, ukuthi engabangela yokuntuleka ebamba isisu kuyinto ukungavumelani immunological lozakwethu.

kokukhulelwa Artificial

Ngosizo lwezobuchwepheshe banamuhla kanye nentuthuko emkhakheni wezokwelapha namuhla kakade izindlela ngempela ephumelelayo lokukhulelwa ingane izindlela ezimbalwa engavamile. Ethandwa kakhulu iyona insemination yokufakelwa. Le nqubo ihilela ekususeni amaqanda sowesifazane amaqanda ambalwa. Ngesikhathi esifanayo, la madoda ukuthatha isidoda, wabageza. Ngalesosikhathi khiqiza amaqanda elivundisiwe. Ngemva kwalokho, izazi podsazhivayut zygote kwakheka umzimba kamama. Kuyaphawuleka ukuthi ithuba sokukhulelwa ngesikhathi esifanayo 25% kuphela ngamunye amaqanda avundiswa. Lesi ngiso sizatfu sekufa avame eyenziwa "iphinde itshalwe" zygotes 4 nje. Lokhu kwandisa kakhulu amathuba okuthi ngempumelelo lokukhulelwa ingane. Kuyaphawuleka ukuthi ezifana amaqanda elivundisiwe ngokuvamile ivumela ukuthuthukiswa amawele.

Kuze kube manje, wonke yokufakelwa insemination isikhungo ilungele banezeluleko ngokugcwele amasevisi ekugxiliseni le zygotes kwesibeletho. Ngakho, ngisho nalabo abazali abaye okuthiwa ukungavumelani immunological, kukhona yithuba elihle uzale izingane zabo ndawonye. kokukhulelwa ezinjalo kungenye kunomthelela kulondolozwe imindeni. Okwamanje, sibonga le ndlela sokukhulelwa, bazalelwa amakhulu ezinkulungwane zabantu, noma izigidi zezingane ephelele.

Uma umbhangqwana oshadile ukuze unyaka owodwa wokuphila ubulili asebenzayo ayengacabangi ingane, bona belulekwa ukuba bafune usizo lobuchwepheshe. Baqale ukuthola isizathu ukungabi sokukhulelwa futhi uma kungekho ezinye izinketho esifanelekayo, cela ukuhlanganyela ukusizakala indlela yokufakelwa. Ngenhlanhla, namuhla akuseyona ayebiza njengasekuqaleni, futhi iyatholakala cishe yonke imindeni.
