Which abdominal fascial layer is continuous with the internal spermatic fascia?

Explanation:
The internal spermatic fascia is continuous with the transversalis fascia. As the testis descends through the inguinal canal, the transversalis fascia becomes the innermost covering of the spermatic cord, forming the internal spermatic fascia. This layering reflects the abdominal wall origins: cremasteric fascia/muscle come from the internal oblique, and the external spermatic fascia comes from the external oblique aponeurosis. The rectus sheath is part of the anterior abdominal wall and does not contribute to the cord coverings.
