It has been taught that the spermatozoa do not acquire motility until after leaving the epididymes. This idea I have recently demonstrated to be erroneous. A young man had suffered from a double epididymitis years before the operation to be described. Recent repeated examinations of the semen had shown constant absence of spermatozoa, although the amount of semen and macroscopic appearance were normal. An anastomosis of the vas with the globus major of one side was suggested, and at the time of the operation I withdrew a few drops of fluid from the neighborhood of the proposed site of incision into the epididymis. This fluid I immediately put on a slide, covered it, and made the examination, the procedure occurring at room temperature. The spermatozoa were found active and, in fact, appeared in no wise different from spermatozoa obtained after ejaculation, and I believe that impregnation could be secured by
