Monorchism:
Most people with a penis have two testicles in their scrotum — but some only have one. This is known as monorchism.
Monorchism can be the result of several things. Some people are simply born with just one testicle, while others have one removed for medical reasons. [healthline]
Noted in “Putin Admits He Has Lost,” Lib Dem FoP, Daily Kos:

I had to go look that one up, as I’ve never seen that word before, or heard that particular bit of information concerning Hitler.
