Ngokuqinisekile, wonke umbhangqwana ohlela ukukhulelwa, uqagela ubulili bomntwana ozayo - umfana noma intombazane. Ikakhulukazi ukukhathazeka ngaleyo mindeni lapho sekuvele ingane. Mhlawumbe isigamu sakho sesibili sithi: "Ngifuna ukukhulelwa intombazane!", Futhi awuhambisani nomsizi womama wesikhathi esizayo, indodakazi enhle. Kusobala ukuthi abazali bayojabula ngendodana kungakhathaliseki ubulili bakhe, kodwa kungani ungazami ukulandela iseluleko indlela yokukhulelwa intombazane ngendlela efanele? Mhlawumbe, kuwe ukuphuma! Ake sibheke izindlela eziyisisekelo zokuhlela intombazane - ezinye zazo zinezesayensi noma zichazwe izibalo, kanti ezinye zibhekwa njengabantu futhi zendabuko.
Ukuhlela intombazane yokuvota nokucabangela umsebenzi wezocansi wabazali bayo
Kuyinto eyaziwa kahle ukuthi ukukhulelwa kungenzeka emva kokuvuthwa - usuku lapho iqanda lihamba ukusuka esibelethweni kuya esibelethweni. Ubulili bendodana engakazalwa buqalwa yisidoda esondla iqanda. Ukuze uhlele intombazane, kuyadingeka ukwethula isilisa nge-X-chromosome. Ukukhuthaza lokhu ngokuphelele ngaphakathi kwamakhono akho. Iqiniso liwukuthi i-spermatozoa ne-X chromosome "izimisele" yabazalwane abasheshayo abane-chromosomes ye-boyish Y. Uma ubulili bezinsuku ezimbalwa ngaphambi kokuvuthwa, amathuba okukhulelwa intombazane aphezulu kakhulu, ngoba kungenzeka ukuthi i-X-spermatozoa eqinile ihlale isiswini futhi ifinyelela ku-ovum. Ngaphezu kwalokho, ngaphambi kokuvuthwa kwegazi, imvelo emgodini iba yinkimbinkimbi, lapho i-Y-spermatozoa ebuthakathaka ifa khona. Ngakho-ke, indlela yokukhulelwa intombazane i-oxydation eyengeziwe yamakhemikhali angasese nge-acetic syringes.
Njengoba uzimisele ukuhlela intombazane, cabanga ngamandla okulala ngokocansi. Ngenxa yenkambiso engavamile ye-X chromosome, amaqanda kulindeleke ukuthi ahlale ezinsukwini ezingu-4-5. Inselele enkulu ukunquma ngokunembile usuku lokuvuthwa kwemfuyo: izinga lokushisa nsuku zonke kumele lilinganiselwe okungenani imijikelezo engu-3, ibalwa yizivivinyo ze-ultrasound noma i-ovulation.
Ukuhlela indodakazi ngendlela yaseChina
Isikhathi lapho kungcono ukukhulelwa intombazane kuzokhonjiswa ngetafula laseChina. Ukuze wenze lokhu, ihlanganisa iminyaka yomama ozayo (ngokuqondile) nenyanga ehleliwe yokukhulelwa. Ngakho-ke, isibonelo, intombazane eneminyaka engama-20 ekhulelwe indodakazi kungenzeka ngoJanuwari, ngoMashi no-Okthoba.
Uqala ukukhulelwa kwentombazane
Ngabe isiphi isimo sengane intombazane engase ikwazi ukukhulelwa? Okungcono kakhulu kubhekwa njengezikhundla ezingenayo ukungena okuncane, isibonelo, ukuthunywa kwezithunywa zevangeli noma isikhundla lapho indoda iseceleni kwayo. Lokhu kungenxa yokuthi insimu idluliselwa kude kakhulu nesisu. I-Rapid Y-spermatozoa ayinayo isikhathi sokufinyelela i-oocyte, ishabalale emvelweni we-acidic, ewuhle kakhulu nge-"girlish" X-spermatozoa.
Ukudla kokukhulelwa kwentombazane
Kukhona ukudla okukhethekile okukhuthaza ukukhulelwa kwentombazane. Qala ukunamathela kuyo kubiza inyanga ngaphambi kokuhlela ukukhulelwa. Ngakho-ke, udinga ukusebenzisa imikhiqizo elandelayo:
- imikhiqizo yobisi: i-cottage shizi, ukhilimu ushizi, ukhilimu omuncu, ubisi;
- imifino: isitshalo seqanda, ikhukhamba, utamatisi, isithombo sebhitrudi, pepper;
- izithelo: ama-apula, amapheya, ama-grapefruit, i-lemon, i-strawberry;
- iziphuzo: itiye, i-cocoa, amanzi amaminerali, ama-herbal teas;
- ukupheka: ukupheka okuzenzela ngaphandle kokusetshenziswa kosawoti nemvubelo.
Indlela yokukhulelwa amawele amantombazane?
Izithuba zokukhulelwa ngamawele ziyakhula uma uhlela izingane ukuba ziqale ngokushesha ngemuva kokuqedwa kwezibeletha zomlomo. Lokhu kungenxa yokuthi ngezinye izikhathi ezimweni ezinjalo ama-ovari aqala ukukhiqiza amaqanda angaphezu kweyodwa emjikelezweni owodwa. Ekugcineni ngifuna ukusho ukuthi amathiphu achazwe ngenhla ukuthi ukukhulelwa kwentombazane anganiki isiqinisekiso esingamaphesenti angu-100, ngakho ungadikibali uma utshelwe yi-ultrasound ukuthi akuyona iphrinta encane okufanele ilinde, kodwa ummeli wakhe.
