Genitourinary syndrome of menopause (GSM) is the medical umbrella term for the collection of vulvovaginal and urinary changes that happen when estrogen falls around and after menopause. It covers vaginal dryness, burning and irritation, painful sex, and urinary symptoms such as urgency, frequency, and recurrent urinary tract infections. GSM is common, it usually progresses without treatment, and — importantly — it is very treatable.
What GSM is (and why the name changed)
You may still see the older term vulvovaginal atrophy or atrophic vaginitis. In 2014, The Menopause Society (then NAMS) and the International Society for the Study of Women's Sexual Health agreed on genitourinary syndrome of menopause as a more accurate, less stigmatizing name. The older terms only described the vagina, but the tissues of the vulva, urethra, and bladder are all sensitive to estrogen, so symptoms cross the whole genitourinary area. "Atrophy" also sounded alarming and clinical for something so ordinary.
The change matters because it captures why one person's main complaint is dryness during sex while another's is a string of urinary infections — the same underlying process, different tissues speaking up.
Why it happens
Estrogen keeps the vaginal and vulvar tissues thick, elastic, and well-lubricated, and it supports a healthy population of protective lactobacilli that keep the vaginal environment slightly acidic. As estrogen declines through perimenopause and after the final period, those tissues become thinner, drier, and less stretchy. Blood flow decreases, natural lubrication drops, and the vaginal pH rises, which shifts the local bacterial balance.
The same tissue thinning affects the urethra and the base of the bladder, which is why urinary symptoms belong under the GSM label at all. This is a normal biological consequence of lower estrogen — not an infection you caught or anything you did wrong.
Common symptoms
GSM symptoms tend to build gradually, and not everyone gets all of them. The most common include:
- Vaginal dryness — often the earliest and most noticeable sign.
- Burning, itching, or irritation of the vulva or vaginal opening.
- Painful sex (dyspareunia), especially with penetration, sometimes with light bleeding or spotting afterward.
- Reduced arousal or lubrication and discomfort that dampens desire.
- Urinary urgency and frequency — a sudden or constant need to go.
- Burning with urination or recurrent urinary tract infections.
- Light bleeding or spotting from fragile tissue.
Unlike hot flashes, which often ease over time, GSM tends to persist or worsen the longer you are postmenopausal, because estrogen stays low. That progressive nature is exactly why it is worth addressing rather than waiting it out.
When to see a clinician first
Before treating symptoms as GSM, it is worth confirming that is what they are. New or changing symptoms deserve an evaluation to rule out other causes — a yeast or bacterial infection, a skin condition such as lichen sclerosus, a sexually transmitted infection, or, rarely, something more serious. A clinician can examine the tissue and check for these.
One rule has no exceptions: any bleeding after menopause warrants a clinician promptly. Even if GSM makes light spotting plausible, postmenopausal bleeding must always be evaluated to exclude other causes. Do not assume it is "just dryness."
The treatment ladder
GSM care is usually a stepwise ladder. Many people do well on the first rung; others move up if symptoms need more. The right step depends on how bothersome your symptoms are, your health history, and a conversation with your clinician.
| Approach | What it is | Best suited for | Access |
|---|---|---|---|
| Moisturizers | Non-hormonal vaginal moisturizers used regularly (every few days) to hydrate tissue over time | Ongoing dryness and daily comfort | Over the counter |
| Lubricants | Water- or silicone-based products used at the time of sex to reduce friction | Painful sex, on-demand relief | Over the counter |
| Vaginal estrogen | Low-dose estrogen delivered locally as a cream, tablet, or ring | Moderate to severe symptoms, including urinary ones | Prescription |
| Vaginal DHEA | A prasterone insert converted to hormones within vaginal tissue | Painful sex and dryness | Prescription |
| Ospemifene | A daily oral non-estrogen medication that acts on vaginal tissue | Those who prefer a pill or cannot use vaginal products | Prescription |
Step one: moisturizers and lubricants
For mild symptoms, non-hormonal products are first-line. Vaginal moisturizers are used regularly, not just around sex, and work by holding water in the tissue to relieve day-to-day dryness. Lubricants are used at the moment of intimacy to cut friction and ease penetration. The two do different jobs and can be used together. Our guide to vaginal dryness after menopause goes deeper on choosing products and easing discomfort during sex.
Step two: vaginal estrogen
When moisturizers are not enough, low-dose vaginal estrogen is a mainstay. Delivered locally as a cream, tablet, or slow-release ring, it restores the tissue rather than masking symptoms, and it is one of the few options that also helps the urinary component — including reducing recurrent UTIs for some people. Because the dose is low and largely local, it is often an option for people who would not take systemic hormone therapy, but that is a decision to make with your clinician, who weighs your personal and family health history. Our overview of hormone therapy explains how the different forms work and the safety conversation to have.
Step three: vaginal DHEA and ospemifene
Vaginal DHEA (prasterone) is a nightly insert that the vaginal tissue converts into small amounts of hormones locally; it is used mainly for painful sex and dryness. Ospemifene is a once-daily oral medication that acts selectively on vaginal tissue without being an estrogen — an option for people who prefer a pill or cannot use vaginal products. All three prescription routes — estrogen, DHEA, and ospemifene — are clinician decisions that weigh your symptoms, preferences, and health history. There is no single "best" one; the right choice is the one that fits you.
A note on lasers and "vaginal rejuvenation"
Energy-based devices (such as fractional CO2 lasers) are heavily marketed for GSM, but the FDA has warned that the safety and effectiveness of these devices for vaginal "rejuvenation" have not been established, and professional bodies including The Menopause Society describe the long-term evidence as limited. Treat these as unproven for GSM rather than an established rung on the ladder, and be skeptical of clinics promising a quick fix.
Living well with GSM
Alongside medical treatment, regular sexual activity or gentle vaginal stimulation helps maintain blood flow and elasticity, and stopping smoking supports tissue health. Avoiding harsh soaps, douches, and heavily fragranced products reduces irritation. Give any treatment several weeks — tissue repair is gradual, and improvement builds over time rather than overnight.
The most important takeaway is that GSM is not something you have to accept in silence. It is common, it is understood, and it responds to treatment. If dryness, discomfort, painful sex, or urinary changes are affecting your comfort or intimacy, bring them up with your clinician. A short, honest conversation is usually the first step to real relief.
