Vaginal estrogen: the overlooked therapy that extends lifespan

Vaginal estrogen therapy stands as a case study in preventive medicine: an accessible, well-tolerated intervention with solid evidence that rarely escapes the gynecology clinic. Applied directly to the vaginal and urethral epithelium, estrogen restores the atrophied mucosa following menopause, reducing recurrent urinary tract infections that in older women can trigger sepsis, hospitalization, and death. Beyond symptomatic relief—dryness, dyspareunia, urinary urgency—the data suggest this local therapy impacts mortality from infectious causes in aging populations. The absence of significant systemic effects, unlike systemic hormone therapy, makes vaginal estrogen an underutilized longevity tool, particularly relevant for biohackers and functional medicine practitioners seeking to optimize female health beyond obvious symptoms.
