	Anatomical terminology

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

Structure

The internal spermatic fascia is derived from the transversalis fascia.[1][2] It is acquired by the spermatic cord at the deep inguinal ring.[1] It has very little lymphatic drainage.[3] It is mainly supplied by sensory afferents and the sympathetic nervous system.[3]
