Akuyona imfihlo ukuthi imibhangqwana yanamuhla isondela ngokucabangela ngokuya ocansini yengane ezayo. Kuze kube manje, kunezindlela eziningi zokuhlela ubulili bomntwana ongakazalwa. Lezi zindlela ziyaqhubeka ziqhubeka phambili. Iningi lalezi zindlela zenzelwe abesifazane ngokwabo.
Namuhla, izindlela ezisetshenziselwa okhokho bethu zibonakala zingenangqondo futhi zihlambalaza kithi. Isibonelo, amakhulu eminyaka edlule abantu bakholelwa ukuthi uma, ngesikhathi sokusebenza kwemishado, beka imbazo ngaphansi komcamelo, umfana wayezozalwa, futhi uma kukhona isando, bekuyoba khona intombazane. Futhi, uma kusetshenziselwa ukwakha indlalifa indoda igqoka ikhanda lomuntu, khona-ke umfana uzozalwa.
Izindlela zanamuhla zokuhlela ubulili bomntwana ongakazalwa zisuswe kude nalawo ngaphambili. Manje banesisekelo sesayensi. Ukubala kuthatha isakhi sezinto eziphilayo, ukudla okusetshenziswe ngaphambi nangesikhathi sokukhulelwa, futhi, yebo, iqembu legazi labazali besikhathi esizayo.
Abesifazane banamuhla banombono othandwa kakhulu ngendlela yekhalenda. Le ndlela isekelwe ekubalweni ngekhalenda. Indlela yekhalenda isekelwe kumaqiniso esayense futhi ezimweni eziningi kuzosiza ukubikezela ubulili bomntwana ongakazalwa.
Isebenza kanjani? Konke kulula ngokwanele. Wonke umuntu uyazi ukuthi umzimba wesifazane usebenza ngebhayisikili. Umsebenzi oyinhloko yale nqubo ukuhlanzwa kweqanda nokulungele ukukhulelwa. Lokhu kubizwa ngokuthi i-ovulation. Ukuvuthwa kwabesifazane kwenzeka cishe phakathi nomjikelezo wanyangazonke. Ngamunye umuntu ngamunye. Isikhathi esihle kakhulu sokukhulelwa yizinsuku ezimbili ngaphambi kokuvuthwa kanye nesonto emva kokuvuthwa. Kufanele ubala ngokufanele futhi unqume ubude bokuvuthwa kwakho. Kodwa lokhu kuphela ukuqala kwazo zonke izibalo.
Njengoba sekuyaziwa ngisho nokusebenza kwesikole, ubulili bomntwana buxhomeke endleleni ama-chromosomes azohlangana ngayo ngesikhathi sokukhulelwa kweqanda. Ukuhlanganiswa kwama-chromosomes XX kungokwentombazana, kanti i-XY ye-chromosome kuya kumfana.
Izibalo ezisuselwa endleleni yekhalenda yokunquma ubulili bezingane ezizayo zisekelwe ekufundeni kwe-chromosome. Le mbono ithi ama-chromosomes e-Y, okungukuthi, amadoda, ahamba phambili, kepha angaphansi kokuqina. Ama-chromosomes e-X, ngokuphambene nalokho, ayenamahloni kakhulu, kepha aqinile kakhulu. Uma ukulala ngokobulili kwenzeke ngaphansi kwelanga ngaphambi kokuvuthwa noma ngokushesha ngemuva kwalokho, ukukhulelwa komfana onamathuba angu-80% kwenzeka. Lokhu kungenxa yokuthi, njengoba sekushiwo ngenhla, ukuthi ama-chromosomes e-Y aneselula kakhulu. Uma ukulala ngokobulili kwenzeke okungaphezu kosuku olulodwa ngaphambi kokuvuthwa kwamaqanda, noma usuku olulandelayo ngemuva kokuvuthwa, khona-ke amathuba okukhulelwa kwentombazane ayanda.
Eqinisweni lale mbono, ososayensi beza ocwaningweni oluningi. Idatha etholakala kulolu cwaningo isenza sikwazi ukuxhumana phakathi kobulili bomntwana nosuku lapho ukukhulelwa kwakhe kwenzeka khona.
Manje akunzima kuwe ukuthi ubale ngekhalenda, lapho intombazane izokhulelwa, nalapho umfana ekhona. Khumbula, ngale ndlela indlela eyinhloko incazelo ecacile yosuku lokuvuthwa. Ukuze unqume usuku oluqondile lwe-ovulation, udinga ukuqapha izinguquko ekushiseni okuyisisekelo, ubheke isakhiwo sokukhishwa. Kodwa namuhla kunendlela ethembeke kakhulu yokunquma ukuvuthwa kwe-ovum - lezi zivivinywa zokuvuna, ezingathengwa kunoma iyiphi ikhemisi.
Uma inqubo ye-ovulation yowesifazane iwela ngqo phakathi nomjikelezo wekhalenda, khona-ke ingacelwa indlela elula yokuhlela ubulili bomntwana ongakazalwa. Eminyakeni engavamile yokuphila komama ezinyangeni eziningana, njengoba ngoFebruwari, Ephreli, Juni, Agasti, njll, umfana cishe ukhulelwe. Futhi, ngokunjalo, amathuba okukhulelwa intombazane ngisho neminyaka yokuphila ezinyangeni ezingavamile, njengoJanuwari, ngoMashi, April, njll, ukwanda.
Yiqiniso, lezi zindlela azinikezi isiqiniseko esinqunyiwe sokunquma ubulili bomntwana. Umzimba wesifazane ngokwawo uyisakhiwo esiyinkimbinkimbi kakhulu. Izinto eziningi zithinta. Uma uhamba ngempela ekuhlolweni, kungcono ukungatholi indlela yekhalenda.
