London - Giving middle-aged women testosterone could boost their sex drive, research suggests.
Administering the hormone via patches, gels and sprays improved sexual desire and pleasure.
Such non-oral treatments also had fewer side effects than testosterone pills, experts said.
The findings raise hope of a new treatment to restore flagging libido in older, post-menopausal women.
The Australian study involved a review of 36 trials involving 8 500 women, 95 percent of whom had gone through the menopause.
