Isidoda esiqandisiwe silingana nesisha ekwelashweni kwe-IVF
Ucwaningo lwakamuva olushicilelwe ku-PLOS ONE luthole ukuthi isidoda esibandisiwe esithathwe nge-biopsy esendaweni yamadlozi (testicular biopsy) sifana nesidoda esisha ekukhiqizeni ukukhulelwa okuphumelelayo nge-IVF. Lokhu kutholakele kufanele kwenze kube lula ukuhlela izinqubo ze-IVF futhi kwandise izinketho ezitholakalayo ezigcineni ezingazali.
IVF (in vitro fertilization) yindlela esiza imibhangqwana enezinkinga zokuzala ukuba ibe nengane. Ngesikhathi senqubo, iqanda lisuswa emaqandeni kowesifazane, lifakwe isidoda sowesilisa esitsheni selabhorethri ukuze lichanyuswe, bese iqanda elichanyusiwe noma i-embryo lifakwa esibelethweni sowesifazane ukuze likhule futhi lithuthuke.
Uma owesilisa enenani eliphansi lesidoda noma engenaso nhlobo isidoda esidodeni — ngokwesibonelo ngenxa yesifo esizuzwe ngokufuzwana noma ngenxa yomdlavuza — khona-ke isidoda esisaphilayo kumele sikhishwe ngqo esendaweni yamadlozi nge-biopsy. Lokhu bese kusetshenziswa khona manjalo njengesidoda esisha, noma kubandiswe ukuze kusetshenziswe esikhathini esizayo.
Le nqubo ibizwa ngokuthi i-intracytoplasmic sperm injection (ICSI) futhi ihilela ukujova isidoda esisodwa eqandeni, esikhundleni sokwengeza isidoda eqandeni esitsheni selabhorethri.
Uma kusetshenziswa isidoda esisha kunqubo ye-ICSI, khona-ke konke okwenzeka kubalingani bobabili kumele kuhlangane kahle ngesikhathi ukuze kwandiswe amathuba okukhulelwa okuphumelelayo.
Kodwa uma isidoda esibandisiwe singasetshenziswa, lokho kwenza lula inqubo yonke ye-IVF kakhulu, ngezindlela eziningi. Ngokwesibonelo, mayelana nesikhathi, owesilisa anganikeza isidoda sakhe kusenesikhathi, kanti mayelana nendawo, i-biopsy ingangabe isenziwa esibhedlela noma ekiliniki efanayo naleyo okufanele aye kuyo owesifazane.
UKenan Omurtag, ongumbhali wocwaningo wokuqala futhi onguprofesa osizayo emkhakheni we-obstetrics and gynecology e-Washington University School of Medicine e-St. Louis, utshele abezindaba wathi: "Ukuba lula nokunethezeka kokukwazi ukusebenzisa isidoda esibandisiwe esithathwe nge-biopsy ku-ICSI kuletha izinzuzo eziningi uma kuqhathaniswa nesidoda esisha.
" Uma inqubo isebenzisa isidoda esisha, owesilisa kumele enziwe i-biopsy yamadlozi ngalo lolo suku noma ngosuku olwandulela usuku iqanda elikhishwa ngalo kowesifazane, kanti lokhu kungase kungababi lula kubo.
Uma kusetshenziswa isidoda esibandisiwe, khona-ke owesilisa angawenza i-biopsy, bese uma kutholakala isidoda, sibandiswe ukuze sisetshenziswe kamuva. Bese, ngesikhathi esibafanele imbhangqwana, owesifazane uthathwa amaqanda, bese kuthi yonke enye ingxenye ye-ICSI, lapho isidoda sjovwa khona eqandeni, iqhubeke.
Udaba lokunethezeka lubalulekile ngoba akusikho nje ukuthi owesifazane angavele angena ekiliniki nanoma yinini lapho ezizwa ekulungele. Ngaphambi kokuba amaqanda akhe akwazi ukuthathwa, kumele anikwe imijovo yama-hormone nsuku zonke izinsuku ezingu-7 kuya kweziyi-10 ukuze kukhuthazwe amaqanda. Futhi lapho amaqanda eselungele ukuthathwa, udokotela uwathola ngeskena le-ultrasound, bese uwakhipha ngenaliti encane kakhulu engenalutho ngaphakathi.
Ocwaningweni lwabo, u-Omurtag nozakwabo bahlaziye imininingwane yeminyaka eyi-15 etholwe e-Washington University Infertility and Reproductive Medicine Center.
Kubantu abesilisa abangu-136 abenzelwe i-ICSI, u-84% wezinqubo wasebenzisa isidoda esibandisiwe kanti abanye basebenzisa isidoda esisha.
Abacwaningi bathole ukuthi isidoda esibandisiwe sisebenza kahle njengesisodwa esisha ku-ICSI uma kubhekwa izinga lempumelelo yokukhulelwa, yize bekukhona umehluko obalulekile wezibalo ezingeni lokuchanyuswa (isidoda esibandisiwe 62%, isidoda esisha 47%).
Baphinde bathola nokuthi uhlobo lwesikhungo noma ikliniki lapho kuthathwe khona isidoda kanye nebanga laso nelabhorethri ye-IVF akuzange kube nomthelela ezingeni lempumelelo yokukhulelwa. Ababambiqhaza kulolu cwaningo benziwa ama-biopsy amadlozi wabo egunjini lokuhlinzela eliseduze nelabhorethri ye-IVF, egunjini lokuhlinzela elinye elakhelene kwesinye isakhiwo esingaba yimayela elikude nelabhorethri ye-IVF, noma esikhungweni sokunakekelwa kwezempilo esiku-ambulatory esingamakhilomitha angu-15 ukusuka elabhorethri ye-IVF.
Umlobi ohambisanayo nowuprofesa we-obstetrics and gynecology u-Randall Odem uthi: "Lolu cwaningo lubonisa ukuthi ukusebenzisa isidoda esibandisiwe esithathwe nge-biopsy kusebenza kahle kakhulu ezimweni eziningi kubaguli mayelana nalokho okubaluleke kakhulu — amazinga okukhulelwa.
" Abacwaningi base-Belgium muva nje bakhombise nokuthi kungenzeka ukuthuthukisa i-nqubo ye-IVF eshibhile engakwazi ukwenza umjikelezo owodwa wokwelashwa ngenani elingaphezulu kancane kuka-$250, okwenza ukuthi ifinyeleleke kubantu abaningi emhlabeni jikelele abangakwazi ukukhokhela indlela evamile, ebiza cishe u-$12,400 ngomjikelezo e-US.
