基于我们的临床经验发现，患有原发性早泄患者的阴茎背神经的数量与正常人的平均数量不一致，平均为2条分支。在这项研究中，我们评估了在中国正常人与原发性早泄患者阴茎背神经的数量与分布，以做出比较。
在这项研究中，我们仔细观察了阴茎背神经、阴茎深背静脉、阴茎背动脉以及深筋膜与白膜之间的阴茎，并且通过尸体解剖对38例成人患者的神经进行计数，此外，128例原发性早泄外科患者的阴茎背神经的数目和分布得到确认。
其中，38例尸检阴茎背神经的数目如下：1例7条分支，1例6条分支、6例5条分支、9例4条分支、14例3条分支、7例2条分支，并且多数背神经相互平行，仅在8例中发现与其他交通支相连。
通过对这38个案例的研究发现，他们阴茎背神经的平均分支为3.55，远远高于正常人，这为原发性早泄的治疗提供了重要的数据支持。

Based on our clinical experience, the number of dorsal penile nerves in patients with primary premature ejaculation (PPE) is not consistent with the average number (2 branches). In this study, we evaluated the number and distribution of dorsal penile nerves among healthy Chinese adults and patients with PPE.
The dorsal nerve of the penis, the deep dorsal vein of the penis, and the dorsal artery of the penis between the deep fascia of the penis and the albuginea penis were carefully educed, observed, and counted in 38 adult autopsy specimens. The number and distribution of the dorsal penile nerve in 128 surgical patients with PPE were determined.
The numbers of dorsal penile nerves of the 38 cases were as follows: 7 branches in 1 case; 6 branches in 1 case; 5 branches in 6 cases; 4 branches in 9 cases; 3 branches in 14 cases; and 2 branches in 7 cases. Most of the dorsal nerves were parallel to each other and in the dorsum of the penis. In only 8 cases, the branches were connected by some communicating branches. In 4 cases, 1 or 2 thin dorsal nerves continued their pathway over the ventral aspect of the penis. The average number of branches of the dorsal penile nerve in patients with PPE was 7.16.
Based on the study of 38 cases, the average number of dorsal penile nerves was 3.55 branches and that of patients with PPE was greater. These preliminary results suggest that the excessive dorsal penile nerves may have an impact on PPE via increased sensitivity and provide topographic data for the possible treatment of PPE.
