Kuyini ukungalingani kofuzo?
I-gynecology yanamuhla ichaza ukuthi imvelaphi yokukhubazeka kwamabhayisikili isuke ingafani nezocansi ezingalingani nabalingani bobulili. Kulesi simo, ochwepheshe batusa ukuhlolisisa kahle lo mbhangqwana ukukhomba noma yikuphi ukungasebenzi okukhulu. Noma kunjalo, ngenxa yezimo eziningi kanye nezimbangela zendawo, akuwona wonke umbhangqwana ovumelana nalolu cwaningo. Yiya kulesi sinyathelo abantu abanesimo esibucayi, abazama ukukhulelwa ingane abazange baphumelele ngenxa yokuhlukumezeka okungapheli.
Eqinisweni, iseli ngalinye lomuntu linalo igobolondo yamaprotheni, ngamanye amazwi, i-leukocyte antigen yomuntu eyenza imisebenzi ethile. Umgomo oyinhloko we-antigen ukutholakala kwamagciwane angaphandle angena emzimbeni ngokuqondile noma ngokungaqondile, kanye nokunikeza umfutho ohlelweni lokuzivikela omzimba oluvimbela "ukutheleleka" kokuqala kwezinhlobo ezihlukahlukene zamzimba ezilimazayo. Ngenxa yalokhu kuvikelwa, ukuzivikela komzimba kuqala ukuthuthukisa imizimba yokuzivikela.
Ukukhulelwa ngempumelelo kwengane, abalingani kumele babe nesethi ehlukene yama-chromosomes, okuthi ngenxa ye-atypicality yabo, yandisa amathuba okukhulelwa okusheshayo embryo nokukhuthazela (amasosha omzimba avikela "ihlumela lothando" ekusongeni okungahle kwenzeke kokukhulelwa kwesisu). Uma kungenjalo, uma isethi ye-chromosome yabalingani ifana kakhulu, i-anti-leukocyte i-antigen ibona ukukhulelwa njengento yangaphandle futhi ibangela inqubo yokwenqatshwa kusukela e-placenta ye-embryo engasebenzi. Ngakho ukungalingani kofuzo komuntu wesifazane nowesifazane.
Kungenzeka yini ukubeletha ngokungafani kwezakhi zofuzo?
Lo mbuzo ubuzwa, mhlawumbe, ngabo bonke abashadile abahlose ukuthola ingane yabo. Kodwa ngaphambi kokukhuluma ngale nkinga, kubalulekile ukuhlolwa. Ukuze uthole idatha kusuka ocwaningweni ngesisekelo sokuhambisana kwezakhi zofuzo, kufanele ubeke phezu kokubekezela okuningi kungakapheli amasonto amabili. Inqubo yalolu cwaningo ihlanganisa izinyathelo zesinyathelo ngezinyathelo zombili abalingani: ukususwa nokuqhathaniswa kwezakhi zofuzo ze-DNA, kanye nokuhlolwa kwegazi kusuka emthanjeni. Imiphumela yokuhlaziywa akumele idlulele izinkomba ngesinye isikhathi, ngoba ama-chromosomes amabili afanayo avele ekhuluma ngokungafani kwamagciwane wesilisa nowesifazane.
Izazi ze-gynecologists zithi ukukwazi ukubekezelela ingane ngokuphelele ngokugcwele uma kugcina izinyathelo ezinqunywe udokotela oya khona, ngoba abalingani, ezimweni eziningi, bahlukumezeka ngokwengxenye, lapho ochwepheshe bekwazi ukulawula kuzo zonke izigaba zokuhlela nokukhulelwa nokubeletha ingane.
Ukungenelela kwezidakamizwa, in vitro fertilization (IVF) noma ukuqothulwa kwamakhemikhali yi-ICSI yichungechunge lwezenzo eziphumelelayo manje ezinikezela abazali abazayo ithuba lokuba obaba nabomkhulu abakhulu. Ukubonisana okuhle kwezakhi zofuzo kukuvumela ukuba ukhethe indlela ngayinye yesiguli ngasinye ngabanye kanye nemibhangqwana eshadile ngokujwayelekile.
