Namuhla kunokwenzeka ukucacisa ubulili bomntwana ngokuthembekile emavikini angu-15-22 okukhulelwa ngosizo lwe-ultrasound. Kodwa kuthiwani uma umama okhungathekile engaphelelwa isikhathi sokuthola ukuthi ubani ozelwe-indodana noma indodakazi, kusukela ezinsukwini zokuqala zokukhulelwa. Kulesi simo, ungangena ezweni lezinkombandlela ezingaqinisekisiwe, imilingo nezinombolo, bese uqhathanisa imiphumela ngesiphetho se-ultrasound. Ngakho-ke, sinikeza abazali abazoba khona ukuthi bajwayele izindlela nezitafula ezidumile kakhulu zokunquma ubulili bemvuthuluka.
Ithebula le-Chinese lokunquma ubulili bomntwana ngenyanga yokukhulelwa
Enye yezindlela zasendulo kakhulu, esekelwe ekuqhathaniseni izinombolo. Ukuze usebenzise ithebula lesikhumbuzo saseChina futhi unqume ubulili bomntwana, udinga ukwazi ukuthi unina unyaka nenyanga lapho ukukhulelwa kwenzeka khona. Yiqiniso, abesifazane abanemijikelezo engavamile ngezinye izikhathi banenkinga, kodwa ngokuvamile, njengoba ucwaningo lubonisa, le nqubo ikuvumela ukuba ubikezele imvuthu yezocansi ngokunemba kwe-90%.
Ngendlela, itafula lokunquma ukukhulelwa kwengane ngokuzalwa komama kanye nesikhathi asivumeli nje ukuthi ucabange ubulili bomntwana, kodwa futhi ukuyihlela.
Yiqiniso, kunzima ukuqonda iphethini enengqondo lapho le ndlela isekelwe khona, ngakho-ke imibono yokungabaza mayelana nokuthembeka kwemiphumela. Kodwa empeleni, uma ungewona umbusi waseChina futhi ubulili bomntwana akuyona into ebaluleke kakhulu, kungani ungazami.
Itafula laseJapane lokukhulelwa ngocansi lomntwana
Ngenxa yokuthi ababusi baseJapane nabo babheka izinto eziza kuqala ngokuphathelene nobulili bendlalifa, kuyinto engokwemvelo ukuthi amaJapane aziqhenya ngokucwaninga kwezinye kule ndawo. Umphumela womsebenzi ovuthiwe ososayensi baseJapane uyithebula lokunquma ubulili bomntwana ngenyanga yokukhulelwa futhi, okuthiwa "inombolo yomndeni".
Ungakwazi ukunquma "inombolo yomndeni" usebenzisa ithebula lokuqala elisizayo, ngokuqhathanisa inyanga yokuzalwa kukababa nomama. Etafuleni lesibili, inombolo "yomndeni" esitholiwe kakade futhi inyanga yokukhulelwa ifaniswa, emgudleni wezinombolo ezimbili, amathuba okuzalwa kwentombazane noma umfana ebonakalayo.

Ithebula lokukhulelwa kwengane ngokuvuselelwa kwegazi
Enye indlela yokubikezela isekelwe ekufundiseni "ukuvuselelwa kwegazi". Kwakusekelwe ekucabangeni ukuthi lo mbhangqwana uzoba nendodakazi noma indodana, kuye ngokuthi igazi laso ngesikhathi sokukhulelwa lincane. Ngakho-ke, kulokhu, ungakwazi ukubikezela phansi kokubala okubalwa ngokulula. Njengoba kunikezwe ukuthi umjikelezo wegazi ovuselelwa kowesifazane uneminyaka engama-3, ngoba owesilisa - 4, ungabala ukuthi igazi lakhe lincane kangakanani. Isibonelo, ngosuku 'lomhlangano okhanukayo' lwesidoda neqanda, lowo oshade naye uneminyaka engu-33 ubudala, nomkakhe 28, manje sizobala: 33: 4 = 8.25 no 28: 3 = 9.3 Ngakho-ke, igazi likababa ngesikhathi sokukhulelwa lincane, ngakho-ke singacabanga ukuthi bazoba nomfana.
Kodwa-ke, usebenzisa le nqubo, kudingeka futhi ucabange ukuthi igazi lingabuyekezwa ngemuva kokulahlekelwa kwegazi elikhulu ngesikhathi sokubeletha, ngemuva kokuhlukunyezwa, ukuhlinzwa, ukuzinikela kwabanikeli.
Ithebula lokukhulelwa kwengane yengane ngenyanga
Kungase kuqinisekiswe ukuthi le ndlela yindlela enokwethenjelwa kakhulu nangokwesayensi. Lapha ngeke uthole amatafula angabazeki namanani wokubala. Konke okudingeka ukwazi ukucacisa ubulili bekusasa lomntwana: lokhu yisikhathi sokuvuthwa nokusondelana.
Ngakho-ke, uma abazali benza uthando ngokuqondile ngosuku lokuvuthwa kwegazi, khona-ke amathuba okuzalwa komntwana aphezulu, njengoba i-Y-spermatozoa engaqiniseki, inethuba elingcono lokuba ngowokuqala ukufinyelela umgomo. Uma ukusondela kwenzeka ezinsukwini ezimbalwa ngaphambi kokukhululwa kweqanda, cishe kungenzeka ukuthi lo mbhangqwana uzothatha intombazane, ngoba kuphela abathwali be-X chromosome bangasetshenziswa izinsuku eziningana.
