Anatomical terminology

The paired Gubernacula (from Ancient Greek κυβερνάω = pilot, steer, also called the Caudal Genital Ligament) are embryonic structures which begin as undifferentiated mesenchyme attaching to the caudal end of the gonads (testes in males and ovaries in females).

Function during development[edit]

As the scrotum and labia majora form in males and females, respectively, the gubernaculum aids in the descent of the gonads (both testes and ovaries).

The testes descend to a greater degree than the ovaries and ultimately pass through the inguinal canal.

Adult structures[edit]

The gubernaculum is present only during the development of the urinary and reproductive organs, being replaced by distinct vestiges in males and females.

Males[edit]
