The Hentai mutation gives the afflicted Canmephian extra groups of male genitalia, almost always totalling in odd numbers. Usually, it causes three sets to be grown, but five is not uncommon. Seven, nine, and more are very rare -- the higher the number, the rarer the sightings. It is not uncommon to see a Hentai-afflicted fur with all his or hir testicles in one scrotal sac.
Polyorchid afflicted Canmephians with Hentai have their added testicles multipled. Ex: A normal fur with an extra pair will have four testicles. A three-cocked Hentai fur will have twelve testicles, irrespective of having a "merged" scrotal sac or three seperate ones.
