Anatomical terminology [edit on Wikidata]

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]
