Women with low libidos appear to get a boost in sexual desire through the use of testosterone patch treatment, according to new research.

Two randomized double-blind, placebo-controlled trials found that post-menopausal women suffering from a lack of sexual desire experienced “significant” improvements in the frequency of “satisfying” sexual activity and desire, as well as a decrease in sexual distress through the use of low-dose, transdermal testosterone patches.

A total of 132 participants from two trials were interviewed after a six-month treatment, according to the research, which is published in the current issue of The Journal of Sexual Medicine.

“More women on testosterone experienced a meaningful benefit (52 percent vs. 31 percent) and, in fact, the odds of experiencing a meaningful benefit on testosterone were 2.4 times greater than that of placebo,” said Sheryl Kingsberg, principal author of the study, in a news release.

Women who experienced a benefit were interested in continuing treatment, Kingsberg said.

The women who reported a positive effect said they had an average increase in sexual activity of 4.4 times over four weeks. In contrast, women who did not experience a benefit had only a 0.5 times increase in activity over four weeks.
