Functional evaluation of HCC and HPRA was performed in organ chambers and wire myographs, respectively.

Similarly, sildenafil-induced relaxations were reduced in HCC and HPRA from ED-VASC but were preserved in ED-RP. Adrenergic contractions induced by EFS in HCC were potentiated in both ED-RP and ED-VASC. EFS-induced nitrergic relaxation was significantly reduced in HCC from ED-VASC but was almost abolished in ED-RP. Fibrous tissue content and cavernosal apoptosis in HCC from ED-RP were not significantly different from No-ED.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Endothelial function and cavernosal sensitivity to phosphodiesterase type 5 inhibitors are preserved in erectile tissue from ED-RP while a marked imbalance in neurogenic modulation of cavernosal tone favoring adrenergic contractile responses over nitrergic relaxation is manifested. Fibrotic and apoptotic processes in cavernosal tissue are not specifically associated to ED-RP.
