the groove on the ventral surface of the embryonic penis that ultimately is closed to form the spongy portion of the urethra.

urethral groove

In the embryo, a midline furrow between the developing genital folds. In the male, the genital folds fuse over the urethral groove, which then becomes incorporated into the distal urethra. In the female, the genital folds remain apart and become the labia minora; the open space between them is the remnant of the urethral groove. See also: groove
