Penile insensitivity is a symptom commonly observed after traumatic or iatrogenic nerve lesions, or in association with neurological or vascular diseases. In contrast, we report 2 cases of intermittent genital hypesthesia that occurred in cyclists after long-term bicycle riding. Anatomical studies show that this condition was probably caused by an irritation of the pudendal nerve during its course through the Alcock canal as reported in the literature. No pathological findings were demonstrated on extensive physical examinations, medical history and all medical imagings (sonography of abdomen, prostate and testes, and magnetic resonance imaging of the pelvis and lumbar spine) as well as radiodiagnostics and Doppler sonography, nor was there evidence of other neurological disturbances. The symptoms in the 2 patients spontaneously resolved after 4 and 7 weeks, respectively, without specific medical therapy.
阴茎感觉减退是创伤性或医源性神经损伤后常见的症状，或与神经或血管疾病相关。相比之下，我们报告了2例长期骑自行车的自行车运动员出现间歇性生殖器感觉减退的病例。解剖学研究表明，如文献报道，这种情况可能是由于阴部神经在穿过阿尔科克管的过程中受到刺激所致。在全面的体格检查、病史询问以及所有医学影像检查（腹部、前列腺和睾丸超声检查，以及骨盆和腰椎磁共振成像）、放射诊断和多普勒超声检查中均未发现病理结果，也没有其他神经功能障碍的证据。2例患者的症状分别在4周和7周后自行缓解，未接受特殊药物治疗。
