IVF iyathuthuka kodwa ezinye izindlela zokwelapha ukungabi nenzalo zigcina izinga lokuzalwa kwezingane eziningi liphezulu
Ubuchwepheshe bokuzala e-United States bunethonya elikhulu ekuvameleni kwamawele, amathtriplets, nezinye izibele ezenzeka ngasikhathi sinye, ngokusho kwezibalo ezintsha ezishicilelwe kwi-New England Journal of Medicine.
UDkt. Eli Y. Adashi, uprofesa wezifo zabesifazane nokubeletha eBrown University, kanye nozakwabo babala ukuthi ngaphezu kwekota eyodwa kwezintathu zokuzalwa kwamawele kanye nangaphezu kwezintathu kwezine zokuzalwa kwamatriplets noma okuzalwa okuningi okwedlula lokho e-United States ngo-2011 kwakuwumphumela wezindlela zokwelapha ukungazali. Nokho, iphesenti lamatriplets noma ngaphezulu elihlobene nosizo lwezokwelapha seliye lehla lisuka esiqongweni samaphesenti angu-84 ngo-1998 ngemuva kokuthi imihlahlandlela ye-in vitro fertilization (IVF) eyayikhuthaza ukugwema ukufakwa kwezimmbewu ezintathu noma ngaphezulu iqale ukusebenza ngalowo nyaka, ngokocwaningo. I-IVF iphinde yathuthuka kwaze kwaba sezingeni lokuthi ukudluliselwa kwesitho sokuzalela esisodwa manje sekuphumelela kaningi ekuzaleni ukukhulelwa okunempilo.
Kodwa ngenkathi kwenzeka lokho, izindlela zokwelapha ukungazali ezingezona eze-IVF ezifana nokuvuselelwa kwamahovary kanye nokukhuthazwa kokuvuthwa kwamaqanda zikhuphukile zaze zaba umthombo oyinhloko wokuzalwa okuningi okusizwa ngodokotela ezweni.
"Lokhu kungumphumela ongahlosiwe wobuchwepheshe obuhloselwe okuhle futhi obumangalisayo."
Abanye omama nabashadile bangase bafise ukuba namawele ngokusebenzisa izindlela zokwelapha ukungazali, kusho u-Adashi, kodwa kaningi ukuzalwa okuningi akufuneki. Kulawo mazwi, uthe abazali abasha nezingane babhekana nobungozi bezokwelapha obungadingekile nezindleko zesikhathi eside zezezimali odokotela okufanele bazame ukuzivimbela. "Sibhekene nenkinga yangempela yokuba nokuzalwa okuningi kakhulu e-United States okunezinkinga kokubili kumama nasezinganeni," kusho u-Adashi, ongumbhali omkhulu wocwaningo nowayengumdwebi omkhulu weWarren Alpert Medical School yaseBrown University.
Ukuzalwa okuningi kuyanda
Umthelela wezindlela zokwelapha ukungazali eminyakeni engama-40 edlule ucacile: Phakathi kuka-1971 no-2011, iphesenti lokuzalwa e-U.S. elalokwenzeka ngokuzalwa okuningi landa laba ngamaphesenti angu-3.5 lisuka kumaphesenti angu-1.8. Noma ngemva kokulungisa ubudala bukamama, izinga lokuzalwa kwamawele landa izikhathi ezingu-1.6 phakathi kuka-1971 no-2009, babika ababhali. Futhi yize amathriplets noma ngaphezulu abangelwa i-IVF ehlele amaphesenti angama-32 ezimeni, esuka kumaphesenti angama-48 phakathi kuka-1998 no-2011, iphesenti lamathriplets noma ngaphezulu abangelwa izinqubo ezingezona eze-IVF lenyuka laba ngamaphesenti angama-45 ezimeni, lisuka kumaphesenti angama-36 esikhathini esifanayo.
"I-IVF iyaqhubekela phambili, ngendlela ethile, ngendlela efanele futhi ilungisa indlela eyayisebenza ngayo, kanti ubuchwepheshe obungewona owe-IVF okungenani bugcina isimo sawo noma bungenza kube kubi kakhulu," kusho u-Adashi. Uye waphakamisa ukuthi, kusukela ohlangothini lwenqubomgomo, okudingekayo ukunweba ukunaka ekuthuthukiseni zonke izindlela zokwelapha ukungazali, lapho ngaphambilini zingazange zibhekwe njengezibaluleke njengaleyo ye-IVF.
