Ejaculatory dysfunction is one of the most common complaints of patients with sexual disorders. While it encompasses several ejaculatory disorders, weak ejaculation is seldom described in the literature. Since the pudendal nerve is the main nerve of ejaculation, we aim to hypothesize that pudendal nerve entrapment could be a cause of weak ejaculation, and that pudendal nerve release could contribute to the improvement of the ejaculatory stream. We presented two cases suffering from a weak ejaculatory stream and sensation of incomplete semen emptying, accompanied with clinical features of pudendal nerve entrapment. Both cases improved after pudendal nerve block and then laparoscopic transperitoneal pudendal release, with a sustained amelioration of the ejaculatory stream after 3 weeks of surgery. Pudendal canal entrapment is therefore a potentially curable cause for weak ejaculation.
射精功能障碍是性功能障碍患者最常见的主诉之一。虽然它包含几种射精障碍，但在文献中很少描述弱射精。由于阴部神经是射精的主要神经，我们假设阴部神经受压可能是弱射精的原因，而阴部神经松解可能有助于改善射精流。我们介绍了 2 例射精无力和精液排空感不完整的患者，伴有阴部神经受压的临床特征。这 2 例患者在阴部神经阻滞和腹腔镜经腹腔阴部神经松解后均得到改善，术后 3 周射精流持续改善。因此，阴部管受压是导致弱射精的一种潜在可治愈原因。
