Epididymo-orchitis; the significance of the condition in industrial surgery.

Epididymo-orchitis, caused by direct trauma, is an uncommon condition, and the history and symptoms are quite different from those of the considerably more common so-called indirect epididymo-orchitis that is ascribed to trauma or strains, and which in symptomatology and clinical course is much like acute, nonspecific, pyogenic epididymitis. The author is convinced that the indirect trauma of muscular strain or minor injuries does not cause epididymitis; it is probable that slight trauma of that sort merely draws attention to an already existing inflammatory process that has made the scrotal area more sensitive than usual.
