A woman went to her doctor for a follow-up visit after the doctor had prescribed testosterone (a male hormone) for her. She was a little worried about some of the side effects she was experiencing.

"Doctor, the hormones you`ve been giving me have really helped, but I`m afraid that you`re giving me too much. I`ve started growing hair in places that I`ve never grown hair before."

The doctor reassured her. "A little hair growth is a perfectly normal side effect of testosterone. Just where has this hair appeared?"

"On my balls."
