The internal spermatic fascia (infundibuliform fascia or Le deuxième fascia de Webster) is a thin layer, which loosely invests the spermatic cord.

The internal spermatic fascia is derived from the transversalis fascia.

[1][2] It is acquired by the spermatic cord at the deep inguinal ring.

[3] It is mainly supplied by sensory afferents and the sympathetic nervous system.
