For millions of women, the symptoms of genitourinary syndrome of menopause (GSM) are an accepted but deeply disruptive part of aging. Vaginal dryness, irritation, and recurrent infections can profoundly affect daily life, yet the condition remains widely underdiagnosed and undertreated.

A Nonsteroidal Alternative

Researchers at the University of Colorado Anschutz Medical Campus have developed a potential alternative that aims to restore vaginal tissue health without relying on conventional steroid hormones. Published in Menopause, the team describes a synthetic flavone, known as 3-fluoro 6,4'-dihydroxyflavone (3F), that regenerated the vaginal epithelium in a preclinical model while showing no evidence of systemic estrogenic activity.

"Over-the-counter methods for treating lubrication may provide enough relief to ease some symptoms... However, they don't address the degenerative changes in the vaginal epithelium." — Steve Nordeen, Pathologist, University of Colorado Anschutz School of Medicine

Mimicking Estrogen Safely

Rather than replacing estrogen itself, the researchers designed 3F to activate the same signaling pathway within vaginal tissue while minimizing exposure elsewhere. The compound has a much lower affinity for estrogen receptors than estradiol and is rapidly metabolized by the liver. In ovariectomized rats, vaginal delivery of 3F restored the thickness and differentiated structure of the vaginal epithelium to levels comparable with estradiol treatment, without stimulating dangerous cell proliferation.
