I happen to be one of very few people who know of this condition that the man has. He had an accident several years ago with some power equipment. Leviticus 21:20 commands that no man present the bread at the temple with damaged testicles..

I think that there are ways of making your point without alluding to a person's disability or misfortune.
Besides, I know of an elder with three testicles. They're even.
