Ubaba unquma ubulili bengane, ngoba unama-gametes ohlobo lwe-X no-Y, kanti lona wesifazane unama-gametes ohlobo lwe-X kuphela. Ubaba, ukuthola ingane nge-XY chromosome, emele umfana. Ngakho-ke kuyadingeka ukuthi isidoda esithwala ama-Y-gametes singene eqandeni, esikhundleni se-X spermatozoa, ukuqinisekisa ukukhula komfana.

Ngalokhu, kunezeluleko ezithile eziqinisekiswe yisayensi ezingakhuphula amathuba okuthi isidoda esingu-Y sifinyelele eqandeni, kepha-ke, azisebenzi ngo-100% futhi zisengabeletha intombazane. Kunoma ikuphi, into ebaluleke kakhulu ukuthi umntwana uhlale etholwa ngenjabulo, kungakhathalekile ukuthi ubulili buni. Uma uzama ukuba nentombazane, hlola okunye okuqukethwe kwethu ngezindlela zokukhulelwa intombazane.

Noma kunjalo, imibhangqwana efisa ukuba nomfana othile ingazama izeluleko ngobufakazi besayensi, ngoba, noma ngabe zigcina zingasebenzi, azithinti impilo yowesifazane, noma yengane.

Amasu aqinisekiswe yisayensi

Azikho izifundo eziningi ezaziwayo mayelana nomthelela wezinto zangaphandle ebulilini bengane, ngaphandle kofuzo. Kodwa-ke, kulabo abakhona, kungenzeka ukugqamisa amasu ama-3 abonakala ekhulisa amathuba okuba nomfana:

1. Ukuba nobuhlobo bobulili eduze ne-ovulation

Ngokuya ngocwaningo olwenziwa eNetherlands ngonyaka ka-2010, ukuya ocansini okuseduze kwenzeka ekuvuthweni kweqanda, kuba maningi amathuba okuba nomfana, ngoba isidoda sohlobo Y sibhukuda ngokushesha kunohlobo lwesidoda X, sifinyelela eqandeni phambilini. Lokhu kusho ukuthi ukuya ocansini kufanele kwenzeke ngosuku olungaphambi kokukhulelwa kweqanda noma ngosuku uqobo, phakathi namahora ayi-12 okuqala.

Ubudlelwano futhi akufanele bube kudala ngaphambi kokuvuthwa kweqanda, ngoba isidoda sika-Y, yize sishesha, futhi kubonakala sengathi sinesikhathi esifushane sokuphila, okusho ukuthi, uma ubudlelwano benzeka isikhathi eside ngaphambili, kuphela isidoda se-X esizobe sisaphila. ngesikhathi sokukhulelwa.

Indlela yokwenza: lo mbhangqwana kufanele uhlanganyele ocansini usuku olungu-1 ngaphambi kokuvuthwa noma ngosuku uqobo, kuze kufike emahoreni ayi-12 ngemuva kwalokho.

2. Khulisa ukudla kwakho i-potassium ne-sodium

I-Potassium ne-sodium ngamaminerali amabili abalulekile futhi abukeka sengathi ahlobene namathuba okuthola umntwana womfana. Lokho kungenxa yokuthi ocwaningweni olwenziwe e-UK, kunemibhangqwana engaphezu kuka-700, kwatholakala ukuthi abesifazane abanokudla okunothe kakhulu nge-sodium ne-potassium babonakala benenani elikhulu lezingane, kuyilapho abesifazane abadla ukudla okunothile nge-calcium ne-magnesium , babenamadodakazi amaningi.

Lo mphumela uphinde waqinisekiswa ocwaningweni olwenziwe eNetherlands ngo-2010 nakwezinye eGibhithe ngo-2016, lapho abesifazane abadla ukudla okunothe nge-potassium ne-sodium baba namazinga empumelelo angaphezu kuka-70% ekufinyeleleni ekubeni nomfana. Ngakho-ke, abacwaningi bathi ukwandisa ukusetshenziswa kokudla okunothile kulawa amaminerali, kanye nokukufaka, kungasiza abesifazane ukuthi bathole umfana.

Yize indlela okwenziwa ngayo ukondla kubonakala kuthonya ubulili bengane kungaziwa, ucwaningo lwaseGibhithe luphakamisa ukuthi amazinga amaminerali angaphazamisa ulwelwesi lwamaqanda, kwandise ukukhanga kohlobo lwesidoda sohlobo Y.

Indlela yokwenza: abesifazane bangakhuphula ukusetshenziswa kwabo kokudla okunothe nge-potassium, njenge-avocado, ubhanana noma amakinati, kanye nokwandisa ukusetshenziswa kwabo kwe-sodium. Kodwa-ke, kubalulekile ukuthi uqaphele ngokudla ngokweqile kwe-sodium, ngoba kungaholela ekukhuphukeni kwengcindezi yegazi nomfutho wegazi ophakeme, kanye nezinkinga ekukhulelweni okuzayo. Ngakho-ke, inhloso ukwenza ukuzivumelanisa nokudla ngokuhambisana nesazi sokudla. Bona uhlu lokudla okuyinhloko nge potassium.

3. Ukuya ocansini ngosuku oluphakeme noma ezinsukwini ezimbili ezilandelayo

Usuku oluphakeme ngumqondo owethulwe ngendlela ye- Izinkokhelo, okuyindlela engokwemvelo yokuhlola isikhathi sowesifazane esivundile ngokusebenzisa izici zomcondo wesitho sangasese sowesifazane. Ngokwale ndlela, usuku oluphakeme lumele usuku lokugcina lapho amafinyila esitho sangasese sowesifazane ewuketshezi kakhulu futhi kwenzeka cishe emahoreni angama-24 kuye kwangama-48 ngaphambi kokukhulelwa kweqanda. Uqonde kangcono ukuthi iyiphi indlela ye- Izinkokhelo.

Ngokocwaningo olwenziwe eNigeria ngo-2011, ukuya ocansini ngosuku oluphakeme noma ezinsukwini ezimbili ezilandelayo kubukeka kwandisa amathuba okuba nomfana. Le ndlela ihambisana nesu lokuya ocansini eduze ne-ovulation, ngoba usuku oluphakeme cishe amahora angama-24 ngaphambi kokuvuthwa kweqanda.

Incazelo yale ndlela nayo ibonakala ihlobene nejubane lohlobo lwesidoda, olubonakala lufinyelela eqandeni ngokushesha. Njengendlela ye-ovulation, ubudlelwano futhi akufanele bube khona ngaphambi kosuku oluphakeme, ngoba isidoda sika-Y kungenzeka singaphili sikhiqize iqanda, kushiye kuphela uhlobo lo-X.

Indlela yokwenza: abashadile kufanele bakhethe ukuya ocansini kuphela ngosuku oluphakeme noma phakathi nezinsuku ezimbili ezizayo.

Amasu angenabo ubufakazi besayensi

Ngaphezu kwamasu afundiwe, kukhona namanye aziwa kakhulu angenabo ubufakazi nhlobo noma obungakafundwa. Lokhu kufaka phakathi:

1. Yidla inyama ebomvu ngaphezulu

Ucwaningo oluningi lukhombisa ukuthi empeleni ukudla komuntu wesifazane kungathinta ubulili bengane, kepha izifundo eziyinhloko zihlobene nokusetshenziswa kwamaminerali athile, njenge-calcium, i-sodium, i-magnesium noma i-potassium, futhi abukho ubufakazi bokuthi ukusetshenziswa kwe inyama ebomvu ingakhuphula amathuba okuba ngumfana.

Yize ezinye izinyama ezibomvu, njenge-veal, inyama yenkomo noma iwundlu empeleni zingaba nokwakheka okukhulu ne-potassium, akuyona indlela engcono kakhulu yezempilo, futhi ukukhetha kufanele kunikezwe okunye ukudla okufana ne-avokhado, upopo noma uphizi. Noma kunjalo, noma yiluphi ushintsho ekudleni kumele luhlale lwanele ngosizo lwesazi sokudla.

2. Ukufinyelela kuvuthondaba ngasikhathi sinye nomlingani

Le ndlela edumile isuselwa emcabangweni wokuthi ngesikhathi kuvuthwa owesifazane ukhipha uketshezi olusiza isidoda esithwala ama-Y-gametes ukuthi sifinyelele kuqala futhi singene eqandeni. Kodwa-ke, azikho izifundo ezihlobanisa umzuzu wokuvuthwa nobulili bengane, futhi akunakwenzeka ukuqinisekisa le ndlela.

3. Sebenzisa itafula lamaShayina

Itafula lamaShayina kade lasetshenziswa njengendlela ethandwayo neyenziwe ekhaya yokukhetha ubulili bengane. Kodwa-ke, ucwaningo olwenziwa eSweden phakathi kuka-1973 no-2006 alutholanga kusebenza ekusebenziseni le ndlela ukubikezela ubulili bengane, noma ngabe sekuhlolwe ukuzalwa okungaphezu kwezigidi ezi-2.

Ngalesi sizathu, itafula laseChina alemukelwa ngumphakathi wezokwelapha ukubikezela ubulili bengane, noma ngabe owesifazane esekhulelwe. Bheka okuningi ngemfundiso yetafula lamaShayina nokuthi kungani kungasebenzi.

4. Isikhundla sokukhulelwa umfana

Le ngenye indlela engazange ifundwe kepha eyakhelwe embonweni wokuthi ukuya ocansini ezindaweni lapho kungena kujule kakhulu kuholela ezingeni eliphakeme lokuba nomfana, ngoba kusiza ukungena kwesidoda sika-Y.

Kodwa-ke, njengoba kungekho zifundo ezenziwe ngale ndlela, akubhekwa njengezindlela ezifakazelwe.
