Polyorchids are persons who have more than two testicles. For a long time the abnormality was not believed to exist, and some of the observers denied the proof by postmortem examination of any of the cases so diagnosed, but there is at present no doubt of the fact,--three, four, and five testicles having been found at autopsies. Russell, one of the older writers on the testicle, mentions a monk who was a triorchid, and was so salacious that his indomitable passion prevented him from keeping his vows of chastity. The amorous propensities and generative faculties of polyorchids have always been supposed greater than ordinary.

...and although there are evidences of the possession of the generative function, still, we are compelled to say that the chances are against fecundity of human cryptorchids. In this connection might be quoted the curious case mentioned by Geoffroy-Saint-Hilaire, of a soldier who was hung for rape. It was alleged that no traces of testicles were found externally or internally yet semen containing spermatozoa was found in the seminal vesicles. 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."
