Testosterone improves sexual function, well-being in postmenopausal women

Nagpur: Although best known as a male hormone, testosterone is important for female sexual health, contributing to libido and orgasm as well as helping to maintain normal metabolic function, muscle strength, cognitive function and mood. Levels decline naturally over a woman’s lifespan, and can also drop sharply following surgical menopause. Prior research has suggested that testosterone therapy can improve sexual function in women, but the available formulations have been designed for men and evidence for their safety or for adverse side-effects in women is scant.
“Our results suggest it is time to develop testosterone treatment tailored to postmenopausal women rather than treating them with higher concentrations formulated for men,” says senior author Professor Susan Davis from Monash University, Australia. “Nearly a third of women experience low sexual desire at midlife, with associated distress, but no approved testosterone formulation or product exists for them in any country and there are no internationally-agreed guidelines for testosterone use by women. Considering the benefits we found for women’s sex lives and personal well-being, new guidelines and new formulations are urgently needed.”
In this study, scientists reviewed 46 reports about 36 randomized controlled trials, conducted between January 1990 and December 2018 and involving 8,480 participants aged 18 to 75 years, approximately 95% of whom were post-menopausal. The trials compared testosterone treatment to a placebo or to an alternative hormone treatment such as oestrogen, with or without progestogen.
