New research suggests a DHEA vaginal suppository for treating vaginal dryness may be one step closer to government approval. The DHEA formulation could provide an effective alternative for women hoping to ease their symptoms of menopause — without resorting to estrogen.

During perimenopause, vaginal tissues begin to atrophy, the lining thins and secretes less and less fluid, and the pH becomes more alkaline, explain the researchers. Not only do these signs of age lead to discomfort during sex, they also increase a woman’s susceptibility to infections and urinary problems. While hormonal treatments may help alleviate such symptoms, many women have a past history of cancer or higher genetic risk for reproductive cancers rendering such medicines unsafe.

As an alternatives to estrogen treatments, some women resort to non-hormonal lubricants. While these products may temporarily provide moisture and even ease sexual pains, they do not correct the physical problems producing the symptoms. By comparison, DHEA (dehydroepiandrosterone) is a precursor of estrogens and androgens and so can induce physical changes that protect the vagina, according to the researchers. That said, the DHEA product in this study is still considered “hormonal” by regulatory authorities, such as the Food and Drug Administration.

Safety Testing a New Product

For the study, a research team from EndoCeutics, a private bio-pharm company, recruited nearly 500 women to participate in a randomized, double-blind, placebo-controlled trial of its DHEA suppository product. The majority of the women, 84 percent, complained of moderate to severe vaginal dryness. The researchers divided the women, ranging in age from 40 to 80, into two groups: 325 women in the DHEA-treatment group and 157 in a placebo group. After a baseline gynecological test, the women used a daily suppository of either the DHEA or placebo, depending on their group, for 12 weeks.

Compared with the women using a placebo, the women who used the DHEA ovules experienced improvements. Their scores on a scale of 0 to 3 for pain during sex dropped 0.36 points more than the women using placebo and their scores improved by 0.27 points with regard to vaginal dryness. Importantly, the gynecologists who examined them saw 86 percent to 121 percent better improvements in vaginal secretions, integrity of the vaginal lining, lining thickness, and tissue color in the women who used DHEA, while their vaginal pH shifted 0.66 points toward acidity (a positive direction).

“The only side effect reasonably related to treatment is vaginal discharge due to melting of the vehicle at body temperature and this was reported in about 6 percent of the participants,” noted the researchers in their study.

Importantly, this therapy has not been tested in patient at risk or with a history of breast cancer.

“Although this medication is considered 'hormonal,' the mechanism appears to be primarily local with minimal side effects beyond vaginal discharge from the suppository," Dr. JoAnn V. Pinkerton, executive director of North American Menopause Society, stated in a press release.
