Ngamhlanje kunokwenzeka ukucacisa ngesondo lomntwana ngokuthembekileyo kwiiveki ezingama-15 ukuya ku-22 zokukhulelwa ngoncedo lwe-ultrasound. Kodwa kuthekani ukuba umama onxungupheko unomonde ukufumana ukuba ngubani ozelweyo-unyana okanye intombi, ukususela kwiintsuku zokuqala zokukhulelwa. Kule meko, ungangena kwihlabathi leengcamango ezingaqinisekiyo, umlingo kunye nenani, uze uthelekise iziphumo kunye nokupheliswa kwe-ultrasound. Ngoko ke, sinikeza abazali abaza kuba baqhelana neendlela ezithandwa kakhulu kunye neetafile ekuqaliseni isondo seemvumba.
Itafile yaseTshayina yokumisela isondo somntwana ngenyanga yokukhulelwa
Enye yezindlela zamandulo, ngokusekelwe ekuthelekisweni kwamanani. Ukuze usebenzise itafile yokubamba isiTshayina kwaye unqume ngesondo lomntwana, kufuneka ukwazi ixesha lomama kunye nenyanga apho ukukhulelwa kwenzeke khona. Ngokuqinisekileyo, abafazi abanesigxina esingenasiphelo ngamanye amaxesha banenkathazo, kodwa ngokubanzi, njengoko uphando lubonisa, lobu buchule buvumela ukuba uqikelele izicucu zesini ngokuchaneka kwe-90%.
Ngendlela, itheyibhile yokumisela ukukhulelwa komntwana ngexesha lobudala nexesha alivumelekanga kuphela ukuba ucinge ngesondo lomntwana, kodwa nokucwangcisa.
Kakade, kunzima ukuqonda indlela enengqiqo ekusetyenziswe ngayo le ndlela, ngoko ke iingcamango zokungathembeki malunga nokuthembeka kweziphumo. Kodwa enyanisweni, ukuba awuyena umbusi waseTshayina kunye nesondo lomntwana kuwe akubaluleke kakhulu, kutheni ungazami.
Itafile yaseJapan yokukhulelwa ngesondo somntwana
Ekubeni abalawuli baseJapan babenemisebenzi yabo ebalulekileyo malunga nokulala ngesindlalifa, kuyinto engokwemvelo ukuba amaJapane aziqhayisa ngamanye uphando kule ndawo. Isiphumo somsebenzi ovelisayo wezenzululwazi zaseJapan yithebhile yokumisela isondo somntwana ngenyanga yokukhulelwa kwaye, kuthiwa "inombolo yentsapho".
Unokumisela "inombolo yentsapho" usebenzisa itafile yokuncedisa yokuqala, ukuthelekisa inyanga yokuzalwa komama noyise. Kwitheyibhile yesibili, i-"number number" esele ifunyenwe kwaye inyanga yokukhulelwa ifaniswa, kwintlupheko yale manani amabini, amathuba okuzalwa kwentombazana okanye inkwenkwana ibonakala.

Itheyibhile yokukhulelwa komntwana ngenxa yokuvuselelwa kwegazi
Enye indlela yokubikezela isekelwe kwingcamango "yokuvuselelwa kwegazi". Kwakusekelwe ekucingeni ukuba isibini siza kuba nentombi okanye unyana, kuxhomekeke kwigazi lalo ngexesha lokukhulelwa elincinane. Ngoko, kulo mzekelo, unokukwazi ukuchaza ubungakanani bomgangatho wezinto ezilula. Ngenxa yokuba umjikelezo wegazi uhlaziywa kumfazi iminyaka engama-3, ngomntu-4, unokubala ukuba igazi lalo lincinci. Umzekelo, ngomhla we "intlanganiso enqwenelekayo" yesidoda kunye neqanda, iqabane lalingeminyaka engama-33 ubudala, kunye nomfazi 28, ngoku siza kubala: 33: 4 = 8.25 kunye no-28: 3 = 9.3. Ngako oko, igazi likayise ngexesha lokukhulelwa lincinane, ngoko sinokucinga ukuba baya kuba nenkwenkwe.
Nangona kunjalo, usebenzisa le ndlela, kufuneka uqwalasele ukuba igazi liyakwazi ukuhlaziywa emva kokulahleka kwegazi elikhulu ngexesha lomsebenzi, emva koxinzelelo, ukuhlinzwa, ukuzinikela kwabanikelayo.
Itheyibhile yokukhulelwa ngesondo somntwana ngenyanga
Ingatsho ngokuqinisekileyo ukuba le ndlela yindlela ethembekileyo kunye nesayensi. Apha awuyi kufumana ietafile ezingathandabuzekiyo nezibalo ze-arithmetic. Yonke into ofuna ukuyifumana ukuqinisekisa ukuba isondo sekusasa lomntwana: lo ngumhla wokuvuthwa nobudlelwane obusondeleyo.
Ngoko ke, ukuba ngabazali bathandana ngokuthe ngqo kumhla wokuvuthwa, okokuba ukuzalwa komntwana kuphakamileyo, ekubeni i-Y-spermatozoa i-Unstable, kodwa iyakhawuleza inethuba elingcono lokuba ngowokuqala ukufikelela kwiinjongo. Ukuba ukusondeleka kwenzeke iintsuku ezimbalwa ngaphambi kokukhululwa kweqanda, mhlawumbi mhlawumbi, loo mbini iya kuba nentombazana, kuba kuphela abathwali be-X i-chromosome banokuhlala bebenokusebenza iintsuku eziliqela.
