神经性阳痿是指各种原因使阴茎勃起中枢和周围神经受损，阴茎不能正常地反射性勃起。阴茎的勃起功能受大脑皮层、皮层下中枢、脊髓神经的支配。脊髓神经位于腰骶髓段。大脑病变、肿瘤、脑血管意外、脑外伤及脑部手术。脑部病变可影响到丘脑垂体功能，丘脑垂体功能受损就会产生激素分泌的紊乱，催乳素和性激素的分泌障碍而影响勃起功能。如果位于腰骶段的神经受损，伤及支配阴茎反射勃起的神经纤维就会发生阳痿。另外，一些脊髓病变，如脊髓肿瘤、脊椎裂、脊髓空洞症、脊髓痨、肌萎缩性侧索硬化病等运动神经元病也是发生神经性阳痿的原因。有关资料报道，多发性神经硬化症有 90%以上的病人患有不同程度的阳痿。糖尿病性神经系统病变，慢性酒精中毒，维生素B12、B6的长期缺乏，这些会使神经纤维肿胀、破裂、空泡化及轴索直径改变，均会导致神经性阳痿。神经性阳痿与精神性阳痿截然不同，它们的临床表现、发病机理、治疗方法均不相同。
