Anatomical terminology |
The primary urethral groove or 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 eight weeks of gestation and becomes closed into a normal male urethra by the twelfth week.
Failure of complete closure can be associated with hypospadias.[1]
