Okokuqala, kufuneka kuthathelwe ukuba abazali bexesha elizayo banokufaka izicelo kwiziko lezonyango ezizodwa, apho baya kuncedwa khona, basebenzisa ubuchwephesha banamhlanje. Kubiza kakhulu. Ukongezelela, esi sibini kuya kufuneka sishiye isondo sobulili sokuzalwa komntwana.
Ukuba ufuna ukukhulelwa ngendlela eqhelekileyo, ke kuwe kukho iindlela onokuzama ukuzenza ukuba unayo unyana okanye intombi.
Yintoni ebonisa isondo somntwana ongakazalwa?
Ukufakelwa kwemfuyo kwenzeka xa iqanda lihlangana nomdlwane, ophethe i-X ye-chromosome okanye i-Y. Owesibini ngumfazi, owesibini ungowesilisa. Ngoko, kuxhomekeke kohlobo lwalo, kuya kuba yintombi okanye unyana.
Indlela eqinisekileyo yokuphatha ngesondo lomntwana ongakazalwa kukuqhagamshelana nomhla wokuhlambalaza ngexesha lokwabelana ngesondo (ukuphumelela kwendlela i-85%). Inyaniso kukuba i-spermatozoa ene-chromosome-Y (yindoda) ihamba ngokukhawuleza kwaye ingaphantsi kunezona zithwala i-X-chromosome, leyo, ngokufanelekileyo, ifinyelele kwisiza sokukhulelwa emva koko. Ukuqhubela phambili kule ndawo, iingcali zicebisa isibini esifuna ukukhulelwa kwinkwenkwe, sithandane ngesondo ngosuku lokuhamba. Ngoko, i-spermatozoa ene-Y-chromosome ngaphambili ifikelela kwiqanda kwaye iyifaka. Xa abazali befuna intombazana, ngoko isondo kufuneka sibe iintsuku ezintathu ukuya kwezine phambi kokuvuthwa. Kuya kubakho oku kulandelayo: "indoda" i-spermatozoa iya kufa, kunye nabathwali be-Y-chromosomes, balinde ukukhululwa kweqanda.
Ukuze usebenzise le ndlela yokucwangcisa, ibhinqa kufuneka ikwazi ixesha lokuhamba. Umhla ubalwa ngokungeza kumhla wokuqala we-ovulation 14 yokugqibela (ukulungiselela umjikelezo oqhelekileyo wokuya esikhathini ukuya kwiintsuku ezingama-28).
Abanye abazali basebenzisa itafile zesiTshayina ukuchonga ixesha lokukhulelwa ukucwangcisa ngesondo somntwana. Oku kuqwalasela ubuncinane bomama kunye nenyanga yokuchumisa.
Kukho indlela yaseJapane, ukuthenjwa kwayo kuthiwa kufinyelele kuma-80%. Ngokutsho kwakhe, kufuneka usebenze kunye neetafile ezimbini. Iyokuqala inquma inani elipheleleyo le sibini. Ngenxa yoko, sifumana kwitheyibhile inyanga yokuzalwa kukayise nonina. Ukusuka kubo siqhuba imigca emibini ukuya ngakwesokudla. Kwi-intersection sithola into ebizwa ngokuba yikhowudi yenombolo. Ukwazi, phendukela kwitheyibhile yesibini. Sifumana inombolo yethu kwaye sibone ukuba inyanga nganye yokukhulelwa ihambelana nenombolo yayo X. Ngaphezu kwabo, kungenzeka ukuba kuzalwa umntwana okanye intombi. Kuhlala kuphela kubazali ukuba bakhethe inyanga.
Indlela yokuvuselelwa kwegazi ithandwa. Kodwa ayiqwalaselwe njengenzululwazi. Ngokweengcali, ukuthembeka kwayo ku-2% kuphela. Le ndlela isekelwe kwinto yokuba igazi lomntu lihlaziywa ngexesha elithile. Kwamadoda, kanye ngeminyaka emine, kwabasetyhini-abathathu. Umzali onomdla omncinci wegazi uchaphazela isondo somntwana. Ukuba ukuhlaziywa kokugqibela kwaba ngumama ozayo, ke intombazana iyazalwa, ukuba upapa unomfana. Kuba kubala kuthatha iminyaka yabazali ngamnye kwaye bahlule: 3 - ukuba ibhinqa, 4 libe yindoda. Ngubani onokulinganisela, yena "nomncinci." Kufuneka kuthathelwe ingqalelo ukuba ukulahlekelwa igazi okukhulu (ukulimala, ukuhlinzwa, ukubeletha) kukhokelela ekuvuseleleni.
Kukho ezinye iindlela zokuchaphazela ngesondo lomntwana ngaphambi kokuba ukhulelwe. Umzekelo, ukulala ngesimo esithile okanye ukulandela ukutya okuqinileyo ngaphambi kokuba ukhulelwe. Kodwa zonke zibangela ukungathandabuzeki phakathi kweengcali kwaye azinika isiqinisekiso esingaphezu kwama-50%.
Ukuba ugqiba, umbuzo wendlela yokucwangcisa ngesondo somntwana, kungakhathaliseki ukuba ufuna inkwenkwe okanye intombazana, uyazi ukuba umntu akanakuhlala echaphazela umphumo wokuphela. Yikholelwa ukuba uMama Uluntu uhlala enza ngobulumko, kwaye uyabathanda abantwana bakho.
