Chiitiko chinotyisa che "kusununguka" kwemazwi akawanda sekutonga kwekupedzisira. Nemafaro nhasi, mishonga haigoni kumira, kupa kune vakaroorana vasingakwanisi kubata mwana zvakangoita, insemination yekugadzira. Vana "kubva mumuviri wechirwere" - ichi chinhu chinowanzoitika mune zvenyika yanhasi. Zvisikwa zvakashata, zvirwere, mararamiro ehupenyu, kutapurirwa kwemabasa - izvi zvose ndizvo chikonzero chokuti chegumi chevanhu vepasi havagoni kubata mwana pachavo.
Fertilization "in vitro"
In vitro fertilization kana iyo yakajairika, izwi rakashandurwa izwi ECO rinonyatsoita se "kukura kunze kwemuviri womunhu." Ichi ndicho chinonyanya kukosha cheyo nzira. Munguva yeVIV, zamu rinotorwa kubva mumuviri wemukadzi achishandisa nhombodo ine tsvina. Usatya izvi - nzira yacho inongotora maminetsi mashomanana uye inopfuura pasi peaneshesia. Uyezve, spermatozoa inobatsira yebaba remangwana inowanikwa mu ovum, uye embryo inowanikwa nenzira iyi inokura mumubatanidzwa kwemazuva mashanu. Panzvimbo inotevera, dhe rinogadzirwa rinowanikwa muchibereko cheamai vanotarisira. Zvakakosha kuziva kuti kubata kwomwana achishandisa IVF kunoshandiswa kune, zvose munyaya yevakadzi nevanhurume vasina vana.
Vana mushure meVIVF
Kwenguva yokutanga, nzira yekugadzirisa insemination yakashandiswa muGreat Britain muna 1978. Kubva panguva iyoyo zviuru zvevana vane utano uye vane utano hwakakwana "kubva mumuviri wekuedza" zvakaonekwa pachiedza - zviuru zvemadzimai zvakawana mufaro wevana, zviuru zvemhuri zvakamirira kuti mwana avepo.
Munharaunda yenzira yekufunga, pane nguva zhinji mave nehuwandu nemanyepo. Vamwe vakangoshamisika kuti vana vakaberekerwa sei mushure meVFF, vamwe vakati vana "kubva mumuedzo tube" vanotambura nezvirwere zvema genetic uye, sekutonga, vakapera shure mukubudirira kubva kune vezera ravo. Uyu maonero haana chikonzero chechikonzero chipi nechipi, sezvo kuberekwa kwevana vakaberekwa naVF kwakafanana zvakafanana neavo vakaberekwa zvakasununguka. Chinhu chete icho vana vanoberekwa mushure meVIV vanogona kusiyanisa nevamwe ndezvekucherechedza kaviri uye kuwedzerwa kutarisirwa, kwakapoteredzwa nevabereki vemucheche "kubva mu test tube".
Kana zviri zvechirwere chetachiona, zvinhu zvose zvinowirirana zvachose ne "zvinyorwa", ndiko kuti, amai nababa. Insemination yekuzvipira inogona kuitika mune dzimwe nguva kunyange kubatsira kusaisa mukana wekutumira kwehutano kumwana. Saka, somuenzaniso, pane zvirwere zvinotapirwa zvinotapurirwa chete kuburikidza nemurume. Muchiitiko ichi, neAVF, zvinogoneka kuronga hutano hwemwana asati aberekwa. Zvakakosha kuziva kuti kusarudzwa kwehutano hwemwana ane IVF inomanikidzwa, iyo inoshandiswa chete nekuda kwezvikonzero zvekurapa.
Akashamisika "kubva mumuviri unoedza"
Kazhinji, nechinangwa chokudzivirira, vabereki vanofara havagamuchiri mwana mumwe, asi pakarepo mapatya, katatu kana kunyange mana. Pane izvi nekuda kwezvikonzero zvakasiyana siyana, imwe yadzo inonzi hyper-stimulation ye maevari, inotangwa pamberi peVIVF.
Mukuwedzera, kuwedzera mikana yekudyara, mazai akawanda anoiswa muchibereko. Ichokwadi kuti nhamba yemashiripiti yakabatanidzwa inokurukurwa nevabereki munguva yemberi, uye nekutanga kwekuzvitakura, zvinoita kuti kuderedza fetus isingadiwi. Asi vasati vaita nzira yakadaro, vanachiremba vanomanikidzwa kunyevera mukadzi kuti kuderedzwa kunogona kukanganisa kusununguka kwepamuviri, naizvozvo zvakanyanya kusingadiwi.
Zvinonyatsova nechokwadi kuti ECO haina kukanganisa utano hwevana nenzira ipi zvayo. Vana "kubva mumuviri wekuyeresa" sekufanana nevamwe vanokura, vachikura uye vanogona kuberekera vana vavo. Zvose izvi zvinoratidza zvakaitika kuna Louise Brown - mwana wokutanga "kubva mumuviri wekuyeresa", uyo wava kutova amai vasina rubatsiro rwezvehutano.
