Uma ufuna ukuba nomntwana, kungokwemvelo ukuthemba ukuthi ukukhulelwa kuzokwenzeka ngokushesha ngangokunokwenzeka. Ukuze wandise amathuba akho okukhulelwa ngokushesha, kubalulekile ukubala usuku lwakho lwe-ovulation ukuze wazi isikhathi esingcono sokukhulelwa.

Ukuze uthole umntwana, kufanele kube nokuvundiswa. Futhi ukuze kube khona ukuvundiswa, udinga i-oocyte ngakolunye uhlangothi nesidoda ngakolunye. Nokho, lokhu kwenzeka kuphela izinsuku ezimbalwa ngomjikelezo ngamunye. Ukuze wandise amathuba akho okukhulelwa, ngakho-ke kubalulekile ukuthola leli “fasitela lokuzala”, isikhathi esifanele sokukhulelwa.

Kulokhu, kubalulekile ukubala usuku lwe-ovulation. Ngemijikelezo evamile, kwenzeka ngosuku lwe-14 lomjikelezo, kodwa abanye besifazane banemijikelezo emifushane, abanye ende, noma imijikelezo engavamile. Ngakho-ke kunzima ukwazi ukuthi i-ovulation kwenzeka nini. Ungasebenzisa izindlela ezahlukene ukuze wazi usuku lwakho lokuvuthwa kwamaqanda: izinga lokushisa elijikayo, ukubhekwa kwamafinyila omlomo wesibeletho nokuhlolwa kwe-ovulation - lokhu kuyindlela ethembeke kakhulu.

Uma usuku lwe-ovulation selwaziwa, kungenzeka ukucacisa iwindi layo lokuzala elicabangela ngakolunye uhlangothi ubude bokuphila kwe-spermatozoa, ngakolunye uhlangothi lwe-oocyte evundisiwe. Ukwazi :

• uma ikhishwe ngesikhathi sokuvuthwa, i-oocyte ivundiswa kuphela amahora angu-12 kuya kwangu-24;
• isidoda singahlala sivundisa esithweni sangasese sowesifazane izinsuku ezi-3 kuya kweziyi-5.

Ochwepheshe batusa ukuya ocansini okungenani zonke ezinye izinsuku eduze ne-ovulation, kuhlanganise nangaphambili. Kodwa-ke, ukwazi ukuthi lesi sikhathi esihle asiqinisekisi u-100% ukwenzeka kokukhulelwa.

Akunakwenzeka ukuphendula lo mbuzo njengoba ukuzala kuncike kumingcele eminingi: izinga le-ovulation, ulwelwesi lwesibeletho, i-mucus yomlomo wesibeletho, isimo samashubhu, ikhwalithi yesidoda. Kodwa-ke, izici eziningi zingathonya le mingcele ehlukene: iminyaka, ukudla, ingcindezi, ukubhema, ukuphuza utshwala, ukukhuluphala ngokweqile noma ukuzaca, ukulandelana kokusebenza, njll.

Nokho singanikeza, okuyinkomba nje, ama-avareji. Ngakho ngokwezibalo zakamuva ezivela ku-INED (1), emibhangqwaneni eyi-100 yokuzala efisela ingane, ama-25% kuphela azozuza ukukhulelwa kusukela enyangeni yokuqala. Ngemuva kwezinyanga eziyi-12, ama-97% azophumelela. Ngokwesilinganiso, imibhangqwana ithatha izinyanga ezingu-7 ukuze ikhulelwe.

Isici esibalulekile okufanele sicatshangelwe imvamisa yokuya ocansini: uma kuningi, amathuba okukhulelwa ayanda. Ngakho esikhathini esingangonyaka owodwa, kwabalwa ukuthi:

• ngokwenza uthando kanye ngesonto, amathuba okukhulelwa angu-17%;
• kabili ngesonto, bangama-32%;
• kathathu ngeviki: 46%;
• izikhathi ezingaphezu kwezine ngeviki: 83%. (2)

Kodwa-ke, lezi zibalo kufanele zilungiswe ngokuvumelana nesici esiyinhloko sokuzala: iminyaka yowesifazane, ngoba ukuzala kwabesifazane kuncipha kakhulu ngemva kweminyaka engama-35. Ngakho, amathuba okuba nengane yilawa:

• 25% ngomjikelezo ngamunye eminyakeni engu-25;
• 12% ngomjikelezo ngamunye eminyakeni engu-35;
• 6% ngomjikelezo ngamunye eminyakeni engu-40;
• cishe ziro ngaphezu kweminyaka yobudala engama-45 (3).

Lapho umbhangqwana uqala "izilingo zezingane", ukuqala kokuya esikhathini kungase kuzwakale njengokuhluleka okuncane njalo ngenyanga. Kodwa-ke, kufanele kukhunjulwe ukuthi ngisho nangokuhlela ukuya ocansini ngesikhathi se-ovulation, amathuba okukhulelwa awekho i-100% emjikelezweni ngamunye, ngaphandle kokuba lokhu kube uphawu lwenkinga yokuzala.

Futhi ochwepheshe bayeluleka ukuthi "bangacabangi kakhulu ngakho", ngisho noma lokhu kunzima lapho isifiso sezingane sikhula ngamandla futhi sinamandla.

Odokotela bakhuluma ngokungabi nabantwana lapho, lapho kungabikho ukuvimbela inzalo kanye nokuhlangana okuvamile (okungenani 2 kuya ku-3 ngesonto), umbhangqwana uhluleka ukukhulelwa ingane ngemva kwezinyanga ezingu-12 kuya kwezingu-18 (uma owesifazane eneminyaka engaphansi kuka-35-36). Ngemuva kweminyaka engama-37-38, kuyatuseka ukusungula ukuhlolwa kokuqala ngemuva kwesikhathi sokulinda esiyizinyanga eziyisi-6 kuye kweziyi-9, ngoba ukuzala kuncipha ngokushesha kule minyaka, kanye nokusebenza kahle kwamasu e-AMP.
