Kwimeko apho isibini esitshatileyo sifuna ukuzithemba ngokupheleleyo ekuzalweni komntwana ophilileyo kunye ozalisekileyo, kuyafaneleka ukunyamekela ukwenza iimvavanyo zofuzo ngexesha lokukhulelwa. Ngokuqinisekileyo, ukhetho olufanelekileyo luya kuphunyezwa kwinqanaba lokucwangcisa ukuzala nokuzalwa komntwana, kodwa ngokuqhelekileyo, abantu bayazi ukuba kungekudala baya kuba ngabazali, ngokungalindelekanga.
Kuziphi iimeko apho kuyimfuneko ukufumana iziphumo zeemvavanyo zofuzo ngexesha lokukhulelwa?
Ukuba umama ozayo uwela "kwiqela elibeka ingozi", ngoko kuyimfuneko ukuba abe nokuhlolwa kunye ne-geneticist. Okubaluleke kakhulu ukuhanjiswa kohlaziyo lwegazi ngexesha lokukhulelwa kwiimeko ezinje:
- unyaka wexesha elizayo unina lidlula iminyaka engama-35;
- kwi-genus yomntwana okhulelwe, ukuzalwa ngokusweleka komntwana okanye izifo ezithandekayo kuye kwenzeka;
- Uhlalutyo lofuzo ngexesha lokukhulelwa luyimfuneko xa umfazi, kungekudala ngaphambi kokuchumisa, athathe iziyobisi, utywala, utshaya okanye uphathwa ngamachiza angamandla;
- Izibonakaliso zolu hlobo lophando ziya kuba ngamathambo angaphambili, isisombululo somthwalo womntwana ofileyo okanye umntwana onentsholongwane.
Musa ukuyihoxisa uhlalutyo lwe-genetics kwabasetyhini abakhulelweyo, ukuba ngaba umama ozayo uza kugula ngesifo esinentsholongwane okanye sisifo esichengayo.
Iintlobo zohlalutyo lwezofuzo zabasetyhini abakhulelweyo
Iindlela eziqhelekileyo ezisetyenziselwa ukufumana ukungaqhelekanga ngokwemizimba yinkcazo yezinto ezinokwenziwa kwegazi kunye nokuhlaziywa kwegazi kunye ne-ultrasound. Ukuba babonisa ubungqina bokuba naziphi na izifo, loo mfazi uya kufuneka aphumeze uluhlu olupheleleyo lweemviwo, njengoku: isampula kunye nokufundisisa i-particle placenta kunye negobolondo yangaphandle ye-fetal (i- chorionic biopsy ), uphando lwe-amniotic fluid, i-cordocentesis nokunye okuninzi. Kodwa nabo bonke abanako ukubonelela umfanekiso opheleleyo, njengoko ukukhulelwa ngamnye kuyinkqubo ekhethekileyo kunye neyodwa.
