Key Features/ Anatomical Relations
The internal spermatic fascia is the deepest of three layers that surround the spermatic cord and testes. It is derived from the transversalis fascia as the testes descend from the abdomen to lie outside the pelvis in the embryo.
Function
The internal spermatic fascia permits a degree of motility between the facial coverings and overlying skin. This movement helps to control the temperature of the testes.
