Abazali abaningi banesifiso esikhulu nephupho lokwengeza indodana noma indodakazi emndenini wabo. Ngezinye izikhathi kungaba ukuqedela umndeni. Ngezinye izikhathi, kungase kube ngenxa yesizinda samasiko omndeni. Futhi, kunezifo ezithile zofuzo ezizuzwa ngobulili obubodwa kuphela. Ukuze bavikele ingane ezifweni ezinjalo, abanye abazali bacabanga ngokuqondile ngobulili bomntwana. Kungakhathaliseki ukuthi yisiphi isizathu, abantu abaningi banombuzo othi, “Ingabe ikhona ngempela indlela yokukhetha ubulili bomntwana esizoba naye?” Ake sixoxe ngalokhu namuhla.
Ithini ngempela isayensi yezokwelapha ngalokhu?
Kalula nje, uma ukhulelwa umntwana ngocansi olujwayelekile, amathuba okuba nomfana noma intombazane angama-50/50. Lokho kusho amathuba amabili alinganayo . Kodwa abantu abaningi bafuna ukubona ukuthi bangawandisa yini la mathuba kancane ukuze bazuze.
Kodwa nansi inkinga evezwa odokotela nochwepheshe bezempilo. Okusho ukuthi, abanye abazali banethemba elikhulu ngalezi zindlela futhi badumala kakhulu uma bengafinyeleli lokho abakulindele. Cabanga nje, kuthiwani uma ulandela indlela ethile unethemba lokuthola indodana, kodwa ugcine unentombazane? Noma kuthiwani uma unendodana njengoba ubufisa, kodwa ingenazo izimfanelo obuzicabanga? Ezimweni ezinjalo, lokho kudumala kungathinta ikusasa lengane kanye nempilo yengqondo.
Ngakho into ebaluleke kakhulu okufanele uyikhumbule ukuthi ayikho kulezi zindlela engaqinisekiswa ukuthi isebenza kahle ngokuphelele. Ezinye izindlela ezidumile zingase zisekelwe ezinganekwaneni.
Empeleni, kuneminye "imidlalo" eyayidlalwa ogogo nomkhulu bethu. Odokotela bayabahleka bathi, "Uma lezo zindlela zingalimazi umama nomntwana, kulungile ukuzizama."
Ingabe izindlela zemvelo ziyasebenza ngempela?
Indlela yemvelo edume kakhulu yokukhetha ubulili bomntwana yindlela kaShettles . Yasungulwa emashumini eminyaka edlule nguDkt. Landrum B. Shettles. Le ndlela isekelwe osukwini lokuvuthwa kweqanda kanye nendawo yokuhlangana ngokocansi.
Iyini indlela kaShettles?
Ngokusho kukaDkt. Shettles, isidoda esidala umntwana wesilisaIsidoda sesilisa (esine-chromosome engu-Y) sincane, siyashesha, futhi siphila isikhathi esifushane. Kodwa-ke, isidoda esidala umntwana wesifazane (esine-chromosome engu-X) sikhulu, sihamba kancane, futhi singaphila isikhathi eside.
Ngakho-ke ngokwalo mbono, uphakamisa into efana nale.
| Uma ufuna | Indlela okufanele ilandelwe (ngokwendlela kaShettles) |
|---|---|
| Umfana | Ucansi kufanele lusondele kakhulu ekuvuthweni kowesifazane ngangokunokwenzeka . Lokhu kuvumela isidoda esingu-Y esisheshayo ukuthi sifinyelele iqanda ngaphambi kwesidoda esingu-X. Futhi, izindawo ezibeka isidoda eduze komlomo wesibeletho (isb., ukungena ngemuva) zingcono kakhulu. |
| Intombazane | Kufanele uye ocansini izinsuku ezimbili kuya kwezine ngaphambi kokukhishwa kweqanda. Ngemuva kwalokho, lapho iqanda selikhishwe, isidoda esingu-Y esihlala isikhathi esifushane sizobe sesifile, kusale kuphela isidoda esingu-X esihlala isikhathi eside nesiqinile. Kuthiwa isikhundla sobuvangeli, lapho indoda iphezulu, ibhekene, yisona sikhundla esingcono kakhulu. |
Nakuba kubikwa ukuthi iShettles Method iphumelele cishe ngo-75%, abanye odokotela bezifo zabesifazane kanye nodokotela bezifo zabesifazane bayangabaza izinga lempumelelo yalezi zindlela zemvelo. Bathi amathuba okuba nomntwana onalezi zindlela noma ongenazo awadluli ku-50/50.
Kodwa-ke, kunombono ohluke ngokuphelele kulokhu. UDkt. J. Martin Young, udokotela, uthi indlela kaShettles empeleni iphumelela ngamaphesenti aphansi angaba ngu-39%. Uveza umbono ophikisana nombono kaShettles.
- Uma ufuna intombazane , yenza ucansi eduze kakhulu nesikhathi sokuvuthwa kweqanda .
- Uma ufuna umfana , yenza ucansi ezinsukwini ezimbalwa ngaphambi kokuvuthwa kweqanda.
Uyabona, akukho ukuvumelana phakathi kochwepheshe abahlukahlukene ngisho nangalezi zindlela zemvelo.
Yiziphi Izindlela Zobuchwepheshe Obuphezulu?
Kukhona futhi amasu amaningana esimanje athi anikeza imiphumela ephumelela kakhulu kunezindlela zemvelo. Lezi ziyabiza futhi azitholakali yonke indawo.
Indlela ye-MicroSort
Lena yindlela eyamukelekayo nephumelelayo yokukhetha ubulili njengamanje. Ihilela ukusebenzisa udayi okhethekile, ukukhanya kwe-laser, kanye nomshini obizwa ngokuthi i-flow cytometer ukuhlukanisa ama-X- kanye nama-Y-sperm. Isidoda esifunekayo sibe sesifakwa ngokwenziwa esibelethweni sowesifazane. Le ndlela ivame ukwenziwa nge- In Vitro Fertilization ( IVF ) .
Ngokusho kwemibiko, le ndlela inezinga lempumelelo elingu-91% kulabo abathemba amantombazane kanye nezinga lempumelelo elingu-73% kulabo abathemba abafana .
Izindlela Eziphikisanayo
Kunezinye izindlela ezimbili, kodwa kunezinkinga ezinkulu zokuziphatha kanye nezomthetho eziphathelene nokusetshenziswa kwazo.
1. Ukuxilongwa Kwezakhi Zofuzo Ngaphambi Kokufakelwa Kwesibeletho (i-PGD): Lokhu kuhilela ukuhlola ama-embryo akhula ngaphandle kwesibeletho sikamama nge-IVF ngaphambi kokuba afakwe esibelethweni, bese kukhethwa kuphela ama-embryo anobulili obufunwayo bokufakelwa.
2. Ukusampula Kwe-Chorionic Villus (CVS): Le ndlela inganquma ubulili bengane ngokuhlola ama-chromosome engane ekuqaleni kokukhulelwa.
Into ebaluleke kakhulu: Kokubili i-PGD kanye ne-CVS empeleni zenzelwe ukuhlola izifo ezingathi sína zofuzo. Ukuzisebenzisa ukukhetha ubulili bomntwana onempilo kubhekwa njengokungafanele emazweni amaningi. Kube nemibiko yokuthi abanye abantu bakhipha isisu lapho bethola ukuthi bakhulelwe ingane yobulili obungafanele ngalezi zindlela. Ngakho-ke, izinhlangano zezokwelapha azincomi ukusebenzisa lezi zindlela ngenhloso yokulinganisela umndeni.
Umlayezo Wokuya Nawe Ekhaya
- Ngokuvamile, unethuba elingu-50/50 lokuba nendodana noma indodakazi.
- Nakuba kunezindlela zemvelo, njengendlela kaShettles, impumelelo yazo ayikaqinisekiswa ngokwesayensi ngokuphelele, futhi kunemibono ehlukahlukene ngisho naphakathi kochwepheshe.
- Nakuba amasu esimanje njenge-MicroSort ephumelela kakhulu, ayabiza kakhulu, ayinkimbinkimbi, futhi awatholakali kalula ezweni lethu.
- Izindlela ezifana ne-PGD kanye ne-CVS zenzelwe kakhulu ukuthola izifo zofuzo. Ukuzisebenzisa ekukhetheni ubulili kuyimpikiswano enkulu.
- Ngaphambi kokuzama noma iyiphi indlela, gcina okulindelweyo kungokoqobo . Kubalulekile ukugwema ukucindezeleka okubangelwa ukudumala.
- Khumbula, okungaphezu kobulili bomntwanaUkuba nengane enempilo yikho okubalulekile.
- Ngaphambi kokuzama noma iyiphi indlela kulokhu, qiniseka ukuthi ukhuluma nodokotela wakho futhi uthole iseluleko esifanele.
