Testosterone therapy: Is it for women?

Some try testosterone to boost a sagging libido, but this therapy is still unproven in women.

You've probably seen those TV ads targeted to men with "low T," a drop in testosterone level that often occurs with age. Because this male hormone is an instrumental component in sexual desire, declining libido is a common symptom of "low T." Men with this condition may be treated with testosterone therapy to improve their sex drive and relieve other symptoms.
