Vaginal Dryness
Vaginal dryness, discomfort, irritation, and painful sex — the symptom that most women suffer in silence because they think it's permanent and untreatable. It is neither.
Biological Mechanism
Estrogen maintains the thickness and elasticity of vaginal epithelium, the acidity of the vaginal environment (pH 3.5–4.5), lubrication via transudate production, and a lactobacillus-dominant microbiome that suppresses pathogenic bacteria. Without estrogen, all of these functions decline simultaneously. The medical term — Genitourinary Syndrome of Menopause (GSM) — reflects that this is not just vaginal: urethral and bladder mucosa are also estrogen-dependent, explaining why urinary frequency, urgency, and recurrent UTIs are components of the same syndrome.
Common Misdiagnoses
Recurrent bacterial vaginosis (the pH shift can cause BV-like symptoms), Vulvodynia or vulvar dermatitis, Interstitial cystitis (bladder symptoms component), Sexually transmitted infection, Psychosexual causes for painful sex (sometimes coexisting)
Evidence-Based Treatments
- 01Local vaginal estrogen (Vagifem, Estring, Ovestin)
The most effective treatment for GSM. Systemic absorption is minimal — safe even for women who cannot take systemic HRT (including some breast cancer survivors, depending on their cancer type and oncologist guidance).
- 02Ospemifene (Senshio)
Oral SERM (selective estrogen receptor modulator) — acts on vaginal tissue without uterine or breast estrogen receptor stimulation. Useful when local application is not tolerable.
- 03Non-hormonal lubricants (long-acting)
Replens and similar hyaluronic acid-based vaginal moisturisers used 2–3x per week maintain moisture between uses. Not as effective as estrogen but appropriate as adjunct or if hormonal treatment is declined.
- 04Systemic HRT
Addresses both GSM and other systemic perimenopause symptoms simultaneously. GSM resolution with systemic HRT takes longer than systemic symptom improvement — local estrogen is still sometimes added.
