Abstract

Objective: To evaluate the efficacy of two common interventions for bothersome postmenopausal vaginal symptoms on improving sexual frequency and pain. Methods: This is a post-hoc analysis of data from a 12-week double-blind placebo-controlled trial that randomized postmenopausal women (ages 45-70 years) with moderate-severe genitourinary discomfort to vaginal 10μg estradiol tablet plus placebo gel (n = 102), placebo tablet plus vaginal moisturizer (n = 100), or dual placebo (n = 100). Outcomes were proportion of sexually active women at 12 weeks, frequency of sexual activity, and pain severity with sexual activity (0-3 scale). Consistent with the original study design, comparisons were made between each active arm and the dual placebo arm. Results: Most women enrolled in the trial, 294/302 (97%), had sufficient data to be included in this analysis. Mean age of participants was 61 years, most were white (88%), college educated (66%), and most reported sexual activity in the month before enrollment (81%). After 12 weeks of treatment, a similar proportion of women in the vaginal estrogen and dual placebo groups reported sexual activity in the past week (50% and 40%; P = 0.10) and the past month (78% and 84%, P = 0.52). Mean (standard deviation) pain with sexual activity scores at 12 weeks were similar between vaginal estrogen (1.0 [1.0]) and placebo (0.9 [0.9], P = 0.52] groups. The proportion sexually active at 12 weeks (35%) and mean (standard deviation) pain severity in the vaginal moisturizer group (1.1 [0.9]) did not differ from placebo (P = 0.36). Conclusions: Compared to placebo, neither low-dose vaginal estradiol nor vaginal moisturizer treatment over 12 weeks resulted in significantly greater increases in the proportions of women reporting sexual activity or improvement in pain scores with sexual activity.
