Pudendal neuropathies are well recognised as part of more generalised peripheral neuropathies; however, focal abnormalities of the pudendal nerve due to cycling-related injuries have been infrequently reported. We describe two patients who developed pudendal neuropathies secondary to pressure effects on the perineum from racing-bicycle saddles. Both were male competitive athletes, one of whom developed recurrent numbness of the penis and scrotum after prolonged cycling; the other developed numbness of the penis, an altered sensation of ejaculation, with disturbance of micturition and reduced awareness of defecation. Both patients improved with alterations in saddle position and riding techniques. We conclude that pudendal nerve pressure neuropathy can result from prolonged cycling, particularly when using a poor riding technique.
阴部神经病变是更广泛的周围神经病变的一部分，这一点已得到充分认识；然而，因骑行相关损伤导致的阴部神经局灶性异常却鲜有报道。我们描述了两名因赛车座对会阴产生压力效应而继发阴部神经病变的患者。两人均为男性竞技运动员，其中一人在长时间骑行后出现阴茎和阴囊反复麻木；另一人出现阴茎麻木、射精感觉改变、排尿障碍和排便意识减退。两名患者通过调整鞍座位置和骑行技巧后病情均有改善。我们得出结论，长时间骑行，尤其是骑行技术不佳时，可导致阴部神经压迫性神经病变。
