The urethral groove is a temporary linear indentation on the underside (ventral side) of the male penis during embryonic development.

In humans, it typically appears around 8 weeks of gestation and becomes closed into a normal male urethra by the 12th week.

Pathology

Failure of complete closure results in a hypospadias.
