Close relation of dorsal nerve of penis/clitoris and pubis, represented by the course of sulcus nervi dorsalis penis/clitoridis has a major impact in surgical disciplines. Exact preparation of the dorsal nerve of penis is crucial in correct performance of conversion of genitalia in patients with transsexualism, in reconstruction of posterior urethra, in hypospadia, during performance of penile blocade during circumcision and in revascularization surgery of erectile dysfunction.
The role of sulcus nervi dorsalis penis in the Alcock's syndrome is discussed.

Injury of dorsal nerve of penis/clitoris leads to hypestesia or anestesia of glans penis/ clitoridis. The injury of dorsal artery of clitoris leads to hematoma.
It is possible to use sulcus nervi dorsalis penis/clitoridis for sexing of isolated pubis for antropological or forensic purposes. Lateral border of sulcus nervi dorsalis penis corresponds to vertical ridge and lateral border of sulcus nervi dorsalis clitoridis to ventral arc - two parameters. which are parts of the Phenice's method for sexing of isolated pubic bones.
