Cooper Fascia

Cooper's fascia (lat. fascia cremasterica Cooperi) is a connective tissue fascia surrounding the spermatic cord and the levator testis muscle.

Cooper's fascia is a continuation of the internal oblique abdominal muscle, which passes onto the spermatic cord. It starts from the inguinal ligament and surrounds the spermatic cord, leaving only the posterior surface free.

Cooper's fascia received its name in honor of the English surgeon and anatomist Astley Paston Cooper (1768–1841), who first described this anatomical structure.
