Her trial involved 49 women either nearing or at menopause, all reporting
sexual dysfunction. "Across the board, there was a significant increase in
sexual satisfaction in the women on the drug compared to the control

reported improved sexual desire, while 72% had greater satisfaction in their
sex lives, 64% had an improved sexual relationship with their partners, 60% had
better clitoral sensation, and 52% had more frequent orgasms.
The placebo effect definitely came into play, as in the men's study, Polan
tells WebMD. In one category, for example, "Thirty percent of women got
