Emuva esikoleni, satshelwa ukuthi ukuzalwa kokuphila okusha kubangelwa umhlangano we-ovum nesidoda. Ngakho-ke, imisebenzi yeqanda empilweni yowesifazane ngamunye kunzima ukugcizelela. Kubangelwa ubungakanani kanye nekhwalithi yamaqanda ukuthi impilo yesifazane yokuzala ixhomeke.
Uhlobo lwamaqanda luphi?
Amaseli e-egg akhiwa kuma-follicles ama-ovari. Ama-ovaries asesifundeni esingaphansi kwesigxobo sesisu: enye ingakwesokudla kanti enye ingakwesobunxele. I-follicles ifomu kuma-ovarie wentombazane esibelethweni, futhi ngesikhathi sokuzalwa, inani labo liba ngu-1.5 million. Ngesikhathi sokuphila, inani lamaqanda aligcini, kodwa, ngokuphambene nalokho, liyancipha njalo.
Oogenesis
Inqubo yokwakheka kweqanda ibizwa ngokuthi i-oogenesis. I-Oogenesis ingahlukaniswa ngezigaba ezintathu:
- Ukukhiqizwa kwezintambo (kwenzeka lapho intombazane isesisu somama).
- Ukukhula kwezintambo (kusukela ekuzalweni kuya ekuthomeni).
- Ukuvuthwa kwe-egg (kuqala ngokushada).
Esigabeni sokuvuthwa kufanele kukhulunywe ngokuningiliziwe. Ukuthuthukiswa kweqanda kuqala ngosuku lokuqala lwenyanga, lapho kusalokhu luzungezwe yi-follicle. Ekuqaleni, ubukhulu be-follicle buphakathi no-1-2 millimitha. Ngendlela ekhulile, ubukhulu beqanda e-follicle kakade cishe ngamamitha angu-20. Cishe ngosuku lwesi-14 lomjikelezo, i-egg ripens. Isikhathi lapho amaqanda ashiya khona i-follicle ifika. Ngemuva kwalokho, uqala ukuhamba eduze kwebhubhisi le-fallopian ukuya kumuntu. Inqubo yokukhululwa kweqanda ibizwa ngokuthi i-ovulation.
Ubuningi be-ovule ngemuva kokuvuthwa kwe-ovulation akungaphezu kwamahora angu-24, lapho amathuba okukhulelwa ahlale ehla. Uma ukukhulelwa kungenzeki, iqanda lifa. Ngokuvamile, phakathi nomjikelezo ngamunye, owesifazane uthola iqanda elilodwa ngalinye.
Indlela yokuthuthukisa ikhwalithi yeqanda?
Ngeshwa, lo mbuzo ovame ukubuzwa uvame ukushiywa ungaphenduliwe. Njengomthetho, akunakwenzeka ukuthuthukisa ikhwalithi yamaqanda, into esemqoka ukuqinisekisa ukuthi le mfanelo ayihloli. Phela, amaqanda omama akhona emzimbeni wakhe yonke impilo yakhe, lapho ahlaselwa khona yizici ezihlukahlukene ezimbi. Phakathi kwazo - izingcindezi, imvelo embi, imikhuba emibi nokunye.
Ukuze kungabangela ukuwohloka kwekhwalithi yamaseqanda amaqanda owesifazane, kufanele kube:
- ukuhola indlela efanele yokuphila, ukukhipha imikhuba emibi;
- gwema izimo ezicindezelayo;
- Yidla kahle.
