Inkcazo yobazali

Iyeza zanamhlanje zinika iindlela eziliqela zokuseka ubudlelwane phakathi komntwana kunye noyise onyanisekileyo. Kuphawulekayo, kodwa, uluntu olunolwazi olunjalo kwiminyaka emininzi edlulileyo, luya kukwazi ukuba imbali yethu yayiya kuvela njani. Yaye yinyaniso, lo mbuzo awuzange umkhathaze ookumkani kunye nabahloniphekileyo, izibongi kunye nabalingisi, kunye nasezintsapho ezilula, ukungathandabuzeki kwakungabonakali kangangoko kunokwenzeka. Ngelishwa, kwanamhlanje inani lamadoda angathandabuzekiyo landa kuphela. Nangona kunjalo, sichasa ukuziphatha nokuziphatha ngokufanelekileyo kwaye siqhubekele kwiingxaki ezixinzezelayo, okanye kunoko, sithetha ngeendlela ezikhoyo zokumisela ubunyana.

Indlela yokuqulunqa izibophelelo zentsapho?

Ngokuxhomekeke kwindlela enamandla ngayo ukungathandabuzeki kweso sityholo, unokukhetha enye okanye iindlela ezininzi zokumisela ubunzima, okuchaseneyo kunye neendleko, ubunzima, i-degree of reliability kunye nemingcipheko ehambelanayo:

1. Indlela elula kodwa eyona nto ibuzwayo yinkcazo yobudlelwane ngokufana kwangaphandle. Nangona kubonakala ukuba iimpawu zangaphandle zibekwe ngokwasemzimbeni, ziyakwazi ukuzibonakalisa ngeendlela ezahlukeneyo. Ukongezelela, akuqhelekanga ukuba abantwana bazalwe ngokufanayo nomama okanye ugogo wabo, kwaye akukho mbuzo waluphi na uhlobo lwenkcazo phakathi koomntwana kunye noyise.
2. Ngomhla wokukhulelwa kunye nexesha lokukhulelwa, abanye abafazi abangathembeki bazama ukucinga ukuba babandakanyeka kwi-karapuza okanye kungekhona. Kule meko, imvelo ingadlala ihlaya elibi kunye namadoda. Inyaniso kukuba i-spermatozoa inokuhlala isebenzayo ukuya kwiintsuku ezingama-5-7, ngoko ke ukuba ithe ibhinqa yayisondelene nomnye umntu emva kweentsuku eziliqela ngaphambi kokuvuthwa, kwaye kunye nobaba ongenamanga - ngosuku lokuvuthwa, ithuba lokuba unxulumane nomntwana lifanayo kubalingani bobabini.
3. Inkcazo yobazali ngeqela legazi kunye neR Rh isekelwe ekuthelekisweni kwedatha echaphazelekayo yomama kunye noyise osolwayo.

Kule meko, ukunyaniseka kweziphumo ezifunyenweyo kuphezulu, kodwa kude kugqibe.

4. Kuze kube yimhla, uvavanyo oluchanekileyo noluthembekileyo lokumisela ubunyana, olwenziweyo ngaphambi kokuzalwa komntwana, luhlalutyo lwe-DNA. Ukunqunywa kobuntwaba nge-DNA ngexesha lokukhulelwa kwinto enokwenzeka kungekudala. Ngokuxhomekeka kwixesha, izinto eziphilayo ezifundayo zingabakho: i-chorionic villi (iiveki ezi-9 ukuya ku-12), i-amniotic fluid (iiveki ezi-14 ukuya kwe-20), igazi le-fetal ukusuka kwintambo yomlomo (iiveki ezingama-18 ukuya kwe-20). Ukuqaphela ukutshatyalaliswa kwe-DNA ngexesha lokukhulelwa kuyinkqubo yokuchitha ixesha kunye neendleko, ngaphandle koko, kubandakanya umngcipheko wokuphazamiseka. Ngoko ke, oogqirha bancomela umonde baze balinde ukuzalwa komntwana, xa isampulu sezinto ezifunyenweyo zophando zilula kwaye zikhuselekileyo. Yonke into efunekayo ukucacisa ubuntwaba emva kokuzalwa komntwana kungenxa yegazi kwi-vein (uyise nomntwana) okanye iiseli zesibindi somlenze esidlekeni, kwaye izikhonkwane okanye iinwele ziya kusetyenziselwa uphando.
