Mustrophy 

A serious and clinical failure of the muscles. Also a lethal disease that ravages cows, birds, and various specimens of penguins. There is no cute except for the milk of the hoopa tree.

"Did you hear about that kid with Mustrophy?"

testicular matrophy 

The slow decay of your manhood after years of matrimony.

I don't know what's wrong doctor. I never get to go out with my friends anymore or watch the game on the weekend. We’re always doing things with my wife’s friends. We joined a book group and go clothes shopping together. Hmm, sounds like a severe case of testicular matrophy to me.
