title: Morphology, distribution and types of valves in the adult male's testicular veins.
abstract: Morphologically, the pampiniform plexuses investigated had, in their majority, no vascular spiraling on the left side, the same occurring on the right side; however, as for the total number of valves, except for those of the pampiniform plexuses, the left side was found contain a greater number of valves. As regards valve types, there is a predominance of double semilunar one on both sides rather than single semilunar valves.
