Origin

The cremasteric vein is formed by small venules that pass from the cremaster layer of the spermatic fascia that contains the cremaster muscle fibers. It also receives contributions from the pampiniform plexus.

Course

The cremasteric vein ascends within the spermatic cord between the internal and external spermatic fascia. It passes through the superficial inguinal ring across the inguinal canal and into the abdominal cavity through the deep inguinal ring. It has a short intraabdominal course before joining the inferior epigastric vein.

The cremasteric vein serves as an alternate pathway for venous return of blood from the testis, which is normally via the testicular vein into the inferior vena cava. Blood may shunt across the pampiniform plexus into the cremasteric vein into the inferior epigastric vein, thus, a potential source of varicocele (Hamada, Esteves and Agarwal, 2015).

Tributaries

There are no named tributaries.

Structures Drained

The cremasteric vein drains the three layers of the spermatic fascia (external, cremasteric and internal), and their contents. These structures make up the spermatic cord.

Vein is a secreted ligand for the Drosophila EGFR receptor homolog (EGFR), and EGFR-mediated activation of the Ras/MAP kinase pathway is essential for longitduinal glial cell survival (Hidalgo et al., 2001).
