New Patch Could Boost Women’s Sex Drives

A study published in the New England Journal of Medicine shows that a testosterone patch, marketed by Proctor & Gamble Pharmaceuticals under the name Intrinsa, can enhance the sex drives of postmenopausal women. The patch is placed on the abdomen like the birth control patch and changed twice a week.

Participants in the study wore a patch that released either 300 micrograms of testosterone a day, a patch that released 150 micrograms, or a placebo patch. Women wearing the 300 microgram patch reported an average increase in their “satisfying sexual experiences” of 2.1 times every four weeks. Researchers called the improvement “modest but significant.”

The study was funded by the manufacturer of the patch, following the FDA’s denial of approval for use of the patch in the U.S. in 2004. The FDA cited a lack of long-term safety data as the reason for denial, and the results of the study indicate that further research is still required.

While one of the minor side effects of the hormone therapy—unwanted hair growth—did not bother any of the test subjects enough for them to discontinue use of the patch, a potential, if tenuous, link to breast cancer is more disturbing.

During the study, four out of 814 women receiving either 150 microgram or 300 microgram doses of the hormone were diagnosed with breast cancer, compared to no women in the placebo group. In an article posted on Health.com, Lead Researcher Susan R. Davis, MD, PhD, of Monash University in Australia, called it a “chance finding” that four women in the treatment groups were diagnosed with breast cancer, noting that four breast cancer diagnoses among 814 women during a two-year period is “not unexpected.”

Nevertheless, it seems like a dangerous chance to take for a drug that yields only modest improvements to a woman’s libido.

Not to minimize the impact that menopause and a lack of estrogen can have on a woman’s sex drive, but I’d urge women to investigate more natural methods to boost their libido first, keeping in mind that the most powerful sex organ is the brain. This may be even more true for women than for men; fantasy alone can be a powerful aphrodisiac, as can sexy lingerie, the right mood, and (of course) the right lover’s touch.  Lack of lubrication is a true physical symptom in postmenopausal women, but there are plenty of safe lubricants available to solve that stumbling block.

Even if Intrinsa does become available as a “viagra for women,” satisfactory long-term safety trials could mean five years or more before the patch finds its way to a drugstore near you. And if the drug alone yields a marginal improvement in the sex lives of postmenopausal women, combining it with natural mood enhancers should raise the bar for amazing sex well into a woman’s golden years.
