Vaginal Estrogen Therapy Restores Sexual Function After Menopause

Sexual health does not have to decline irreversibly after menopause, yet many women experience significant dysfunction — and many go untreated. This review, published in Maturitas by researchers at the University of Pavia, asks a pointed question: how well does local estrogen therapy (LET) actually address the full spectrum of sexual dysfunction associated with menopause?

The authors focus on genitourinary syndrome of menopause (GSM), a condition encompassing vulvovaginal atrophy, dryness, irritation, and painful intercourse driven by estrogen withdrawal. LET is already the standard of care for GSM, delivered in multiple formulations including tablets, soft gel inserts, vaginal rings, creams, and gels using either estradiol or conjugated equine estrogens at low or ultra-low doses. This review synthesizes evidence across these formulations to evaluate effects on the key domains of sexual function: desire, arousal, lubrication, orgasm, pain, and satisfaction.

The strongest and most consistent evidence supports LET's benefit for dyspareunia — painful intercourse — which is among the most common and impactful sexual complaints postmenopause. There is also reasonable evidence for improvements in arousal, lubrication, and satisfaction. However, effects on sexual desire and orgasm are less well established, pointing to the biopsychosocial complexity of female sexuality that local estrogen alone cannot fully address.

A notable gap identified is that most research treats LET as a single drug class rather than comparing specific formulations, limiting clinicians' ability to make tailored prescribing decisions. Evidence in women with breast cancer — who are often denied systemic hormone therapy — is also sparse.

The authors conclude that managing GSM is central to preserving sexual longevity and overall quality of life. They call for an evidence-based standard of care that accounts for individual symptom profiles and treatment goals, framing sexual health maintenance as a legitimate and important longevity objective for postmenopausal women.
