Testicular and epididymal appendages are embryologic remnants of the mesonephric duct and paramesonephric, respectively. These appendices are subject to a torsion causing condition known as acute scrotal syndrome. This study aimed to determine the variations of testicular and epididymal appendices, registering its presence and size. We studied 30 cadavers of adult individuals, Brazilians, aged 18 and 70, fixed in formaldehyde 40%, provided by the Laboratory of Descriptive and Topographic Anatomy of the Federal University of Alagoas (UFAL), Maceió, Brazil. By dissecting these, the presence of the respective appendixes were identified, which were measured with a manual caliper (Metrica), recording its length and width. The testicular appendices were observed in 41 testes (68.3%) and epididymal appendices in 15 cases (25%). The average length was 4.9 mm (SD=1.7) for the appendix testis and epididymis to 5.2 mm (SD=2.4). With respect to the width of the appendices, the average recorded were 3.2 mm (SD=1.7) and 2.6 mm (SD=0.9) for testicular and epididymal, respectively. The data obtained can be used as morphological support in urological clinical and testicular surgery.
