Spermatozoa have been found days and weeks after castration, and the individuals during this period were capable of impregnation, but in these cases the reservoirs were not empty, although the spring had ceased to flow.

Beigel, in Virchow's Archives, mentions a cryptorchid of twenty-two who had nocturnal emissions containing spermatozoa and who indulged in sexual congress.

Partridge describes a man of twenty-four who, notwithstanding his condition, gave evidences of virile seminal flow.
In some cases there is anomalous position of the testicle.

Hough mentions an instance in which, from the great pain and sudden appearance, a small tumor lying against the right pubic bone was supposed to be a strangulated hernia.

There were two well-developed testicles in the scrotum, and the hernia proved to be a third.
