I believe you’re never fully out of the woods…

Agreed. I explained more in a sibling comment, but this always confused me…

The “they want to be even” explanation is what I remeber being told by the urologist who untwisted me. I was, to be fair, young and in pain, so I don’t know that I remember clearly.

(Also, it was around 25-30 years ago, so I get to be wrong about this.)

Apparently (and this is from memory, so caveat emptor) when young the balls can be uneven. During puberty, one might say “Oh no! I must become even!” and twist up on itself.

This is resovled (at least in my case) with a local anesthetic and manual untwisting. Followed by a procedure where they sew your balls to your sack so they can’t try it again.

I had this as a teenager. Would not recommend.
