Okokuqala, kufanele kuthiwa abazali abazayo bangasetshenziswa ezikhungweni zezokwelapha ezikhethekile, lapho bazosizwa khona, besebenzisa ubuchwepheshe bamuva. Kuyabiza kakhulu. Ngaphezu kwalokho, lo mbhangqwana kuzodingeka ulahle ukuziphatha ngokobulili ngokobulili ekukhulelweni kwengane.
Uma ufuna ukukhulelwa ngendlela evamile, khona-ke kuwe kukhona nezindlela ongazama ngazo ukuthonya ukuthi unendodana noma indodakazi.
Yini enquma ubulili bomntwana ongakazalwa?
Umanyolo uvela lapho iqanda lihlangana nesidoda, esithwala yi-X ye-chromosome noma i-Y. Owesifazane ungowesifazane, owesibili ungowesilisa. Ngakho, kuxhomeke kohlobo lwayo, kuyoba yindodakazi noma indodana.
Indlela eqinisekisayo yokuthinta ubulili bomntwana ongakazalwa ukuhlobanisa usuku lokuvota ngesikhathi sokulala ngokocansi (ukusebenza kahle kwendlela engu-85%). Iqiniso liwukuthi i-spermatozoa ene-chromosome-Y (yindoda) ayashesha futhi engazimisele kakhulu kunabathwali be-X-chromosome, okuthi, ngokufanayo, ifinyelele isayithi lokukhulelwa kamuva. Ukuqhubeka kulokhu, ochwepheshe bayeluleka umbhangqwana ofuna ukukhulelwa umfana, abe nobulili ngosuku lokuvota. Ngakho-ke, i-spermatozoa ne-Y-chromosome ngaphambili ifinyelela iqanda futhi ilitshale. Uma abazali befuna intombazane, ngabe ucansi kumele lube yizinsuku ezintathu kuya kwezine ngaphambi kokuvuna. Kuyoba khona okulandelayo: "i-spermatozoa" yesilisa izofa, kanye nabathwali be-Y-chromosomes, balinde ukukhululwa kweqanda.
Ukuze usebenzise le ndlela yokuhlela, owesifazane udinga ukwazi isikhathi sokuvota. Usuku lubalwa ngokungeza ngosuku lokuqala lokuvota okwedlule 14 (umjikelezo ojwayelekile wezinsuku zokuhlala esikhathini esihlala izinsuku ezingu-28).
Abanye abazali basebenzisa itafula le-Chinese ukuthola isikhathi sokukhulelwa ukuze bahlele ubulili bomntwana. Lokhu kucabangela ubudala bomama nenyanga yokukhulelwa.
Kukhona indlela yaseJapane, okuthenjelwa kuyo kuthiwa kufinyelele ku-80%. Ngokusho kwakhe, udinga ukusebenza ngamatafula amabili. Owokuqala unquma inani lenani lababili. Ngenxa yalokhu, sithola etafuleni inyanga yokuzalwa kukababa nomama. Kusuka kubo siqhuba imigqa emibili phansi nangakwesokudla. Emgumbini sithola ikhodi ebizwa ngokuthi ikhodi. Ukwazi, phendukela etafuleni lesibili. Sithola inombolo yethu futhi sibone ukuthi inyanga ngayinye yokukhulelwa ihambelana nenombolo X. Ngaphezu kwalokho, kungenzeka ukuthi kuzalwa indodana noma indodakazi. Kuphela kuphela ukuthi abazali bakhethe inyanga.
Indlela yokuvuselelwa kwegazi iyathandwa. Kodwa akubhekwa njengesayensi. Ngokusho kochwepheshe, ukuthembeka kwayo kungu-2% kuphela. Le ndlela isekelwe eqinisweni lokuthi igazi lomuntu libuyekezwa nge-periodicity ethile. Emadodeni, kanye ngeminyaka emine, kwabesifazane - kwaba abathathu. Umzali onesifo esincane kakhulu usithinta ubulili bomntwana. Uma isibuyekezo sokugcina singomama ozayo, khona-ke intombazane izalwa, uma upapa unomfana. Ukubala kuthatha iminyaka yabazali ngamunye futhi bahlukanise: 3 - owesifazane, 4 indoda. Ubani obhalansi, yena "nomncane." Kumele kukhunjulwe ukuthi ukulahlekelwa kwegazi okunzulu (ukulimala, ukuhlinzwa, ukubeletha) kuholela ekuvuseleleni.
Kunezinye izindlela zokuthinta ubulili bomntwana ngaphambi kokukhulelwa. Isibonelo, ukulala ocansini kwezinye izinto noma ukulandela ukudla okuqinile ngaphambi kokukhulelwa. Kodwa konke kubangele ukungabaza phakathi kochwepheshe futhi banganiki isiqinisekiso sokungaphezu kwama-50%.
Uma unquma, umbuzo wendlela yokuhlela ucansi wengane, kungakhathaliseki ukuthi ufuna umfana noma intombazane, yazi ukuthi umuntu akanakuthonya ngaso sonke isikhathi umphumela wokuphela. Kholelwa ukuthi uMama Nature usebenza ngokuhlakanipha, futhi uthande izingane zakho.
