Stockholm: A testosterone skin gel, used daily, can boost libido and increase well-being in post-menopausal women.

According to researchers at the obstetrics and gynaecology department at Karolinks Hospital in Stockholm, women with low levels of libido responded to using 10mg a day of the gel.

The doctors said that it had a positive effect on several aspects of their sexual life inlcuding frequency of sexual activity, orgasm, arousal, fantasies and sexual interest.

The researchers found that testosterone levels increased more than tenfold during treatment. Testosterone, although thought of as a male sex hormone, is produced in small amounts by women and is required for a healthy sex drive. Low testosterone levels have been associated with hair loss and lethargy.
