re: https://www.straightdope.com/21342044/did-hitler-have-only-one-testicle
Having myself been born with only a single testicle, I have often wondered how common this is…?
As a child my father took me to a doctor who told both of us that “approximately 5%” of boys are born this way.
(In my case, the doctor thought it might be simply an “undescended testicle” rather than a single testicle, which, he said, is far more common.)
Any other males out there care to admit to this or am I truly a rarity…?
