Abstract
INTSHAYELELO:
Ngaphandle komdla wengqondo ehambelana nokuvuswa ngokwesondo kwamadoda, izifundo ezimbalwa ziphande iindlela ze-neural eziphantsi kwe-psychogenic erectile dysfunction (ED). Nangona ezi zifundo zibonise imimandla emininzi yobuchopho esebenzayo kwizigulana ze-ED ngexesha lokuvuselela okubonakalayo, amandla okuthintela ukuphendula ngokwesondo akukacaci.
AIM:
Olu phononongo luphande amandla emimandla yobuchopho ebandakanyekayo kwi-psychogenic ED.
IINDLELA:
I-Functional magnetic resonance imaging (fMRI) kunye nepenile tumescence (PT) ngaxeshanye zisetyenziselwe ukufunda umsebenzi wobuchopho okhutshwe kwizigulane ze-17 ezingaphandle kunye ne-psychogenic ED kunye ne-19 yolawulo olunempilo ngexesha lokuvuselela okubonakalayo. Iipateni zokusebenza kwengqondo ezinxulumene nezigaba ezahlukeneyo zokuphendula ngokwesondo kumaqela amabini zithelekiswe.
IINGXELO ZEMISEBENZI:
Ukurekhodwa ngaxeshanye kweempendulo ze-fMRI ezixhomekeke kwinqanaba le-oxygen kunye ne-PT ngexesha lokuvuselela okubonakalayo.
IINKCUKACHA:
Ngexesha lokuvuselela okubonakalayo, ukuqaliswa okukhulu kwabonwa kwiqela lesigulane kwi-parietal lobe ephezulu ekhohlo, i-ventromedial prefrontal cortex, kunye ne-posterior cingulate cortex, ngelixa iqela lokulawula libonise ukusebenza okukhulu kwi-insula ephakathi ekunene kunye ne-dorsal anterior cingulate cortex kunye ne-hippocampus. Ngaphezu koko, i-lobe ye-parietal ephezulu ekhohlo ibonise ukusebenza okukhulu kwizigulane kunokulawula ngokukodwa ngexesha lokugqibela lokuphendula ngokwesondo.
UKUQINISWA:
Iziphumo zethu zibonisa ukuba, phakathi kwemimandla esebenza ngakumbi kwiqela lezigulane, i-parietal lobe ephezulu yasekhohlo idlala indima ebalulekileyo ekuthinteleni ukuphendula ngokwesondo. Uphononongo lwangaphambili lubonise ukuba i-parietal lobe ephezulu ekhohlo ibandakanyeka ekubekweni kweliso lokumelwa komzimba wangaphakathi. Ukusebenza okukhulu kwalo mmandla kwizigulane ngexesha leempendulo zesondo zokugqibela kubonisa ukubeka iliso eliphezulu lokumelwa komzimba wangaphakathi, mhlawumbi okuchaphazela impendulo yokuziphatha. Ezi ziphumo zibonelela ngengqiqo kwiindlela zobuchopho ezibandakanyekayo kwi-psychogenic ED.
