Ukwandisa iminyaka yobudala kungakhuphula ingozi yengane yakho yezimo ezithile
Owesifazane uzalwe ngamaqanda onke azokwenzela impilo yakhe yonke. Ngakho-ke uma uneminyaka engu-30 uma ukhulelwa, iqanda owakhulelwe nalo lineminyaka engu-30 ubudala. Uma uneminyaka engu-45 uma ukhulelwa, khona-ke iqanda okhulelwe nalo lineminyaka engu-45 ubudala. Njengoba amaqanda adala, cishe kuzoba namaphutha angabangela amathrikhi , kufaka phakathi i-trisomy 21 (Down syndrome) .
Ingabe Ubudala Bukababa Bubala?
Amadoda angenza isidoda ngokuqhubekayo empilweni yabo yonke. Ngakho-ke indoda ingaba ngu-45, kodwa isibalo esivela sona singase sibe amasonto ambalwa kuphela. Njengoba imbumbulu iselula, kucatshangwa ukuthi ivikelwe ku-Down syndrome nakwezinye izifo. Ngenkathi ubaba wengane engenzi lutho engozini yezinto ezingavamile ze-chromosome, amadoda awakhuni i-hook. Iminyaka yobudala yasemoyeni yathinta kakhulu amathuba okuthola ezinye izifo zofuzo ezifana ne-achondroplasia ( dwarfism ), i-Marfan syndrome (i-genetic syndrome evezwe yizinkinga ezide nobuhlungu bezinhliziyo) nezinye izifo ezidumile ezizenzekelayo.
Iyini Iminyaka Ephakeme Yomama?
Iminyaka yobudala engumama iyigama lezokwelapha elisetshenziselwa ukuchaza abesifazane abakhulelwe abangaphezu kweminyaka engama-35. Leli gama liyaziwa kakhulu njengoba inani elikhulayo labesifazane asebekhulile likhulelwa. Ngenkathi useneminyaka yobudala obudala ingakhuphula amathuba okuba nomntwana onesifo se-Down syndrome, nayo inezinye izinkinga zempilo.
Ngubani okufanele abe nokuhlolwa kokubeletha?
Ngaphambi kuka-2007, i-American College of Obstetrics ne-Gynecologists (i-ACOG) isetshenziselwa ukuncoma ukuthi bonke abesifazane abangaphezu kweminyaka engama-35 banikezwe ukuhlolwa kokuhlolwa kokubeletha okufana noku-amniocentesis kanye ne- chorionic villus sampling . Lapho uneminyaka engama-35, ingozi yakho yokuba nomntwana onenkinga ye-chromosomal ingaba ngu-1 ngo-200 futhi ingozi yokuba nokuphutha kwesisu kusuka kum-amniocentesis kucatshangwa ukuthi i-1 ngo-200.
Njengoba lezi zindleko zacatshangwa ukuthi zifana, 35 zithathwe njengeminyaka eyisikhathi esinconywayo yokuhlola ukuhlolwa.
Ngo-2007, i-ACOG ishintshe isiqondiso sayo lapho abesifazane abakhulelwe kufanele banikezwe ukuhlolwa kokubeletha. Izinto ezimbili zithonya lolu shintsho kumgomo. Okokuqala, baqaphela ukuthi ingozi yokuphuphuma kwesisu ngaphandle kwe-amniocenteis yayingaphansi kwe-1 ku-200 (cishe 1 kuya ku-500). Owesibini wenziwa ngenxa yokwehlulelwa kwezidakamizwa ezibhekene nezidakamizwa lapho abesifazane abancane beba nabantwana abane-Down syndrome kodwa abazange banikwe ukuhlolwa kokubeletha.
Kubalulekile ukuqaphela ukuthi imihlahlandlela ye-ACOG ibhekisela kulabo okufanele banikezwe ukuhlolwa kokubeletha. Abaphakamisi bonke abesifazane ukuba bahlolwe, nje ukuthi bonke abesifazane kufanele banikezwe ukuhlolwa. Kungcono kuwe ukuthi unqume ukuthi ngabe ufuna ukuhlolwa kokubeletha noma cha, nokuthi ngabe yiluphi uhlobo lokuhlolwa, uma lukhona, lungcono kuwe nokukhulelwa kwakho.
Kunezici eziningi okufanele uzicabangele uma wenza isinqumo mayelana nokuhlolwa kokubeletha. Ngaphambi kokuba uhlole ukuhlolwa, kubalulekile ukuqonda ingozi yakho yokuba nomntwana onokungajwayelekile kwe-chromosomal, kanye nokuthi ungenzenjani ngemiphumela engalindelekile.
