Dorsal penile nerve block surgery involves selectively severing some branches of the dorsal nerve of the penis. Its main risks are that if too few nerves are cut, it may not achieve the therapeutic purpose, and if too many are cut, it could affect the erectile function of the penis, resulting in impotence, or even cause numbness or dullness in the local area, leading to an inability to ejaculate. Therefore, dorsal penile nerve block surgery should be cautiously considered and not used as a routine method for treating premature ejaculation.
