An international study, led by Monash University's Professor Susan Davis has confirmed steroid patches can significantly increase the sex drive of postmenopausal women not using hormone replacement therapies.
It is the first study in the world to show that when used alone, testosterone administered by a skin patch significantly improved sexual well-being in postmenopausal women.

The study concluded that in postmenopausal women not receiving estrogen therapy, treatment with a patch delivering 300 µg of testosterone per day resulted in a modest but meaningful improvement in sexual function. The long-term effects of testosterone, including effects on the breast, remain uncertain.
