基於我們的臨牀經驗發現，患有原發性早泄患者的陰莖背神經的數量與正常人的平均數量不一致，平均爲2條分支。在這項研究中，我們評估了在中國正常人與原發性早泄患者陰莖背神經的數量與分佈，以做出比較。
在這項研究中，我們仔細觀察了陰莖背神經、陰莖深背靜脈、陰莖背動脈以及深筋膜與白膜之間的陰莖，並且通過屍體解剖對38例成人患者的神經進行計數，此外，128例原發性早泄外科患者的陰莖背神經的數目和分佈得到確認。
其中，38例屍檢陰莖背神經的數目如下：1例7條分支，1例6條分支、6例5條分支、9例4條分支、14例3條分支、7例2條分支，並且多數背神經相互平行，僅在8例中發現與其他交通支相連。
通過對這38個案例的研究發現，他們陰莖背神經的平均分支爲3.55，遠遠高於正常人，這爲原發性早泄的治療提供了重要的數據支持。

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.
