Results In the dorsal of penis, the DNP were mainly parallel distribution, the number of DNP 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, the average number of DNP was (3.55±1.2) branches. Conclusion The DNP have different pattern of innervation with more than 2 branches, these findings may aid in planning primary premature ejaculation surgical procedures.
