The gubernaculum is the hyaluronic acid-rich column of extracellular matrix which spans between the inferior pole of the gonad and the scrotum. Its non-contractile shortening is what 'pulls' the testis to its adult position.

When passing through the abdominal wall, the testis descends laterally to the rectus abdominis. This occurs through the deep and superficial inguinal rings, the latter of which is found in the inguinal (Hesselbach's) triangle, the medial border of which is the rectus abdominis (the inferior border is the inguinal ligament, and the lateral border is the inferior epigastric vessels).

The descending testis must pass through the parietal peritoneum. This results in a connection known as processus vaginalis. This connection closes, seals and disintegrates during development, leaving the tunica vaginalis covering the testis in the adult scrotum.
