The spermatic fascia (three layers) surrounds the spermatic cord.External spermatic fascia is derived from the external oblique.Cremasteric fascia from the internal oblique.Internal spermatic fascia from the transversalis fascia.Contents of the spermatic cord are detailed in Table 12.1.

As the vas deferens enters the inguinal canal, it takes with it a thin layer of fascia derived from the transversalis fascia, called the internal spermatic fascia. Further down the canal, it collects a covering of muscle fibres and fascia from the internal oblique muscle. These coverings are called the cremaster muscle and cremasteric fascia. Finally, as the vas passes through the external ring, it acquires another thin layer of fascia derived from the external oblique aponeurosis and called the external spermatic fascia.

Mirilas et al. provided a different point of view regarding the internal spermatic fascia (Mirilas et al. 2008; Mirilas 2011). They suggested that the sheath around the internal spermatic vessels is a continuation of the membranous layer of the extraperitoneal fascia from above the internal inguinal ring. Similarly, the vas deferens and its vessels are surrounded by a membranous layer. These findings are in agreement with ours, except that, in their study, the two membranous layers are located inside the internal spermatic fascia. They concluded that the two membranous layers attach posteriorly to the internal spermatic fascia by two short pedicles. Our findings are dissimilar to their interpretation of the internal spermatic fascia and also with their finding on the pedicles. In our study, the internal spermatic fascia refers to the sheath wrapping around the internal spermatic vessels, an observation that is held by many studies. However, in their study, the internal spermatic fascia refers to the sheath that surrounds the two membranous layers and their contents. Here, we found that the two membranous layers and their contents are surrounded by the external spermatic fascia and the cremaster rather than by the internal spermatic fascia as interpreted by Mirilas et al.
