In 10 formalin-preserved adult male cadavers, dissection of the penile veins, arteries and nerves revealed information of clinical importance. The main venous drainage of the corpora cavernosa is via the cavernous veins, with additional drainage through the circumflex, deep dorsal, and crural veins. The arterial supply of the cavernous bodies varied remarkably, and the incidence of an accessory internal pudendal artery was high. The cavernous nerves, previously believed to be microscopic structures, were in fact identifiable grossly, and we were able to follow them from the region of the hilum of the penis to the prostate. The nature of these nerves was then confirmed by serial histologic sectioning. This detailed knowledge of the venous drainage and arterial and nervous supply of the penis, as well as of the relationships among the cavernous structures in the hilum of the penis, can elucidate the cause of erectile dysfunction and provide a valuable guide for surgical correction of vasculogenic and neurogenic impotence.
在10具用福尔马林保存的成年男性尸体上，对阴茎的静脉、动脉和神经进行解剖，揭示了具有临床重要性的信息。海绵体的主要静脉引流是通过海绵体静脉，此外还有通过旋静脉、阴茎背深静脉和脚静脉的引流。海绵体的动脉供应差异显著，副阴部内动脉的发生率很高。海绵体神经以前被认为是微观结构，实际上肉眼即可识别，我们能够追踪它们从阴茎根部区域到前列腺的走行。然后通过连续组织切片证实了这些神经的性质。对阴茎静脉引流、动脉和神经供应以及阴茎根部海绵体结构之间关系的详细了解，能够阐明勃起功能障碍的病因，并为血管源性和神经源性阳痿的手术矫正提供有价值的指导。
