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 youve been giving me have really helped, but Im afraid that youre giving me too much. Ive started growing hair in places that Ive 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 testicles, which is something else I want to talk to you about…, replied the lady.
