Ngexesha lookhokho bethu, kwakungekho ndlela enjalo, kwaye kwakungekho ne-ultrasound, engayenza isondo somntwana ngokuchaneka ngokuthe tye nakwixesha lokukhulelwa. Kule minyaka, abantu baqhube ukujonga okungafaniyo, okuphawulwe kunye nokubhalwa kweenkcukacha ezithakazelisayo, kwaye iziphumo zokungqinelana kwazo zidluliselwe kwisizukulwana esilandelayo. Ngoko ke, unyaka unyaka, amatafula kunye neekhalenda ezininzi zadalwa, ngoncedo apho kwakunokwenzeka ukuqikelela ukuba yeyiphi na umntwana wesini eya kuzalelwa ngabo okanye abo bazali.
Enye yeendlela ezithandwayo namhlanje ekuqaliseni isondo somntwana ongakazalwa unetafile yeVanga. Ngaphandle kwegama, le tafile yayingabonakali yimboni enkulu, kodwa ngumfundi wakhe uLyudmila Kim. Oomama abaninzi bayaqaphela ukuba le ndlela yayibavumela ukuba baqikelele ngokuchanekileyo ngokuchanekileyo okuza kuzalwa.
Kule nqaku, siza kukuxelela indlela yokujonga ngesondo lomntwana kwitafile zeVanga, kunye nokunika iindlela zesayensi abathi abanye babesilisa nabantwana basebenzise kwisigaba sokucwangcisa umntwana wabo.
Cwangcisa ngesondo somntwana etafileni iVanga
Itafile ilandelayo:
Ukuchonga ngesondo somntwana kuVanga, kubalulekile ukuba ulungelelanise iipamitha ezi-2 kuphela-iminyaka yobudala bomama ngexesha lokukhulelwa kunye neenyanga zekhalenda apho le mvelaphi yenzeka khona. Inqumba ebomvu eluhlaza iya kuqikelela ukuzalwa kwenkwenkwana, kunye nokukhanya okuluhlaza kwintombazana.
Ingxaki ebalulekileyo eyenzekayo xa usebenzisa le tafile yinto yokuba inqabileyo inqabileyo iyazi umhla ochanekileyo xa umntwana wakhe ekhulelwe. Ukongezelela, ngamanye amaxesha ukukhulelwa kwenzeka ngokukhawuleza kwinyanga leyo xa umama ozayo uza kuzalwa, apho kunzima ukuyiqonda iminyaka yakhe.
Kukho uluvo lokuba abesifazana abane-Rh factor badinga ukusebenzisa ikhalenda yeVanga ukukhetha isondo somntwana "ngokuchaseneyo." Nangona kunjalo, kwimibhalo yombhali wetafile uLudmila Kim akukho datha kule nto.
Ungayichaza njani ngesondo somntwana ozayo ngokuchaneka okuphezulu?
Ukusuka kwinqanaba lezesayensi, ikhalenda yeVanga, njengawo nawuphi na, ayithathwa njengokwethenjelwa. Ukungahambi kakuhle kwezesondo zomntwana osele sele uzalwe kunye nelo liqikelelwe ngetafile kunokwenzeka ukuba yengozi nje. Okwangoku, kukho iindlela ezivumela abazali bexesha elizayo ukuba baceba ukuzalwa kwonyana okanye intombi ngokuchaneka kwezesayensi:
Ukukhulelwa kwenkwenkwe okanye intombazana incike kuphela kwindoda efaka iqanda-X okanye u-U. Ukuba unomdla ekuzalweni komntu ozayo, umsebenzi wakho kukunyusa inani kunye nokusebenza kwe-U-spermatozoa. Ekubeni "igrukki" ihamba ngokukhawuleza kunokuba "iksy", yenza uthando ngenjongo yokukhulelwa kwenkwenkwezi oyifunayo ngokuthe ngqo ngomhla we-ovulation - ukuze bakwazi ukufikelela kwiqanda ngokukhawuleza.
Ukongeza, ekubeni i-Y-spermatozoa ihlala ingancinane, kuyimfuneko ukuzama ukwandisa ixesha 'lokusebenza kwabo'. Ngenxa yoko, umfazi kufuneka adle ukutya okunotye kwi-sodium ne-potassium. Ezi zimbiwa, ukungena egazini lomama ozayo, ziguqula ubudibanisi besini, ngaleyo ndlela zenze ukuba kunyuke ekusebenzeni kwe-S-spermatozoa.
Ukuzalwa kwentombazana, ngokuchaseneyo, kubalulekile ukuba uqale ukulala ngesondo ngaphandle kweentsuku ezingama-3-4 phambi kokuqala kwe-ovulation - kule ngxaki inokwenzeka ukuba iqanda liza kuzaliswa yi-X-type spermatozoon iphakamileyo kakhulu.
