The amorous propensities and generative faculties of polyorchids have always been supposed greater than ordinary.

Russell reports another case of a man with a similar peculiarity, who was prescribed a concubine as a reasonable allowance to a man thus endowed.
Morgagni and Meckel say that they never discovered a third testicle in dissections of reputed triorchids, and though Haller has collected records of a great number of triorchids, he has never been able to verify the presence of the third testicle on dissection.

Some authors, including Haller, have demonstrated heredity in examples of polyorchism.

There is an old instance in which two testicles, one above the other, were found on the right side and one on the left.

Macann describes a recruit of twenty, whose scrotum seemed to be much larger on the right than on the left side, although it was not pendulous.
