Indlela yokunquma ubulili bomntwana

Lapho owesifazane ezwa ukuthi ukhulelwe, isinqumo esibalulekile esilandelayo kwakuwukucacisa ubulili bomntwana. Wonke umuntu unesithakazelo sokwazi ukuthi ngubani ozovela emndenini wabo - indodakazi noma indodana. Kodwa uma abanye bengesifiso nje kuphela, futhi nesidingo sokuhlobisa i-nursery ngokufanelekile, khona-ke kwabanye kubaluleke kakhulu, ngoba kunezifo ezithile ezizuzwa njengefa futhi zidluliselwa ngocansi. Kulokhu, ukuthola ubulili bezingane ezizayo kuyindaba ebalulekile.

Siza imithi

Ososayensi sekuyisikhathi eside bevela ngezindlela eziningi zokunquma ubulili bomntwana ongakazalwa. Sinikeza izindlela ezinhlanu eziyinhloko.

1. I-Ultrasound iyindlela efinyeleleka kakhulu futhi ephephile. Ucwaningo olwenziwe luqhubeka phakathi nokukhulelwa hhayi nje kuphela ukufunda u-sex, kodwa futhi ukulandela ukuthuthukiswa kwe-fetus. Futhi nakuba i-ultrasound inikeza ukwaziswa okunokwethenjelwa cishe kuzo zonke izimo, kodwa kungenzeka kube nezinhlobo zonke zezimo ezingalindelekile. Isibonelo, udokotela ngeke akwazi ukubona izibonakaliso zobulili kanye nengane, noma izinyane lizobuyela emuva kwabangaphandle.
2. Amniocentesis. Leli gama eliyinkimbinkimbi lisho ukuhlaziywa okhethekile okusekelwe ekuhloleni kokubunjwa kwe-amniotic fluid. Ngendlela, ubulili bezingane ezizayo zingatholakala kakade ngesonto 14. Kodwa njengoba le nqubo ihlotshaniswa nengozi ethile kokubili umama nengane, yenziwa kuphela uma kukhona ingozi yangempela ekuthuthukiseni i-fetus ngenxa yezici zofuzo.

3. Olunye uhlaziyo, i-Cordocentesis, lusekelwe ekutadisheni ketshezi. Kodwa lesi sikhathi ngaphansi kwe-microscope yilona legazi lezintambo. Njengokwesikhashana esidlule, odokotela bahlola ukubunjwa kwe-chromosomal yendaba.
4. Ukuhlolwa kwe-DNA kunikeza isiqiniseko esiphelele sokunqunywa kocansi. Ngo-2007, ososayensi base-United States bathola ukuthi egazini lomfazi okhulelwe kukhona i-DNA ye-DNA yomntanakhe. Ngaphezu kwalokho, inqubo ingenabuhlungu futhi ayihlotshaniswa nanoma iyiphi ingozi. Okubi kuphela ukuhlaziywa okubiza kakhulu.
5. Ukuhlolwa kobulili ngokwemigomo yomsebenzi kufana kakhulu nezindlela zasekhaya zokwenza ukukhulelwa. Kusekelwe eqinisweni lokuthi emcinini womama kukhona inani elithile lama hormone ocansi wezingane ezingakazalwa. Umdwebo uhlotshaniswa ne-reagent ekhethekile futhi uma ungena emcimbini udwetshwe kumbala othile. Green kusho ukuthi umfana uzozalwa, nentombazane orange.

Izindlela ezingezona zendabuko

Futhi ugogo bethu bafunda kanjani ngensimu yengane yesikhathi esizayo? Phela, ngaleso sikhathi zonke izindlela ezingenhla azikwenzi, futhi i-curiosity yayingeke ibe yinto encane. Imithi yendabuko ikhuluma ngezindlela eziningana ezinjalo.

• I-pendulum. Indandatho yomshado iboshelwe intambo futhi iphoswe ngesisu somama. Kuncike ekuhambeni kwempahla futhi uthole ukuthi ucansi. Uma i-pendulum iguquka embuthanweni - kuyoba nentombazane, futhi kusukela kolunye uhlangothi kuya komunye - umfana.
• Ukuphambuka. Le ndlela yasungulwa yizigciwane zezinkinga ngokwazo, futhi, njengoba kuvele, liyiqiniso ngempela. Uma ungalalela futhi ubale inani lezinyosi zenhliziyo, yenzeni. Emantombazaneni kufanele enze impikiswano engaba ngu-140 ngomzuzu, futhi kubafana - okungenani.
• Ngokubukeka nokuziphatha kowesifazane okhulelwe. Kukholelwa ukuthi ekulindeni kwendodana owesifazane uba ngcono, futhi lapho indodakazi izalwa, ukubukeka kubonakala, ngoba kukholwa ukuthi amantombazane "asusa ubuhle" bomama. Uma udonsa inyama nosawoti - kuyoba khona indodana, futhi umnandi, ufulawa nezithelo zikhuluma ngokuzalwa kwentombazane.
• Esimweni sesisu. Sekuyisikhathi eside sekukholelwa ukuthi uma isisu sikhulelwe, kuyoba khona indodakazi, futhi uma ikhomba-ke yindodana. Noma kunjalo, le ndlela ayisoze ithembekile ngaso sonke isikhathi.
