Dorsal penile nerve dissection surgery mainly treats men with overly sensitive dorsal penile nerves, and is generally only applicable to men with a higher number of dorsal penile nerves than the general population, requiring adequate evaluation before surgery. However, after dorsal penile nerve dissection, men may experience erectile dysfunction and even impotence in middle and old age. There is also the possibility of non-ejaculation after the operation due to the local sensitivity of the glans penis decreasing a lot due to the nerve dissection. If there is no ejaculation or no easy ejaculation for a long time, it may easily lead to male infertility, and at the same time, it may bring adverse effects to male sexual desire as well as sexual psychological stimulation, which will affect the life between husband and wife. Therefore, in clinical treatment for premature ejaculation, local alternative treatment with drugs is generally advocated, and performing dorsal penile nerve surgery is not recommended, but unless there is a clear number of dorsal penile nerves developing more than the average person, 1-2 branches can be selectively dissociated, which can significantly reduce the extreme sensitivity of the glans.
