libido · 12 min read
If your sex drive has quietly disappeared and intimacy has become uncomfortable, you're not broken and you're not alone. Here's what's really happening in your body — and the layered, evidence-based approach that actually helps.

Low libido and vaginal dryness in menopause are both driven by falling oestrogen and fluctuating testosterone, which thin vaginal tissue and dampen desire at a neurobiological level. In my practice, this is one of the most common patterns I see in women over 40 — and it's treatable, not something to simply endure. Understanding the mechanism is the first step to getting your body, and your confidence, back.
Let's start with the honesty this topic deserves: something is genuinely changing, and it isn't in your head. Roughly 80% of women report some decline in sexual desire during the menopause transition (source: https://get.myalloy.com/symptoms/low-libido), and clinically, low sexual desire is reported by up to 55% of women during menopause (source: https://pmc.ncbi.nlm.nih.gov/articles/PMC6780739/). These aren't fringe experiences — they are the norm, even though almost no one talks about them at dinner parties.
The biology is layered, and this is where I think most articles stop too early. Declining oestrogen thins and dries the vaginal walls, a condition now called Genitourinary Syndrome of Menopause (GSM), which replaced the older term "vaginal atrophy" because it better captures how widely this affects the bladder, urethra, and vulva — not just the vagina. Vaginal dryness affects 56% of postmenopausal women, and 87% of those women believe it is a direct factor in their reduced libido (source: https://pubmed.ncbi.nlm.nih.gov/19237616). That's an important number, because it tells us women themselves are already connecting the dots between tissue health and desire — the medical world has simply been slower to formalise it.
What I've learned from 20 years of working with women through this transition is that libido loss isn't one thing — it's usually two. I call it Primary Libido Loss and Secondary Libido Loss. Primary loss is neurobiological: oestrogen and testosterone changes affect brain regions involved in arousal and desire directly. Secondary loss is behavioural — it's the avoidance that builds after even one or two painful sexual experiences. The body learns, quite sensibly, to protect itself from discomfort, and desire retreats as a defence mechanism. This is dyspareunia's quiet legacy: pain doesn't just hurt once, it rewires expectation.
Here's a gap I rarely see addressed clearly: it isn't only low testosterone that matters, but the volatility of it. Research shows women with significant testosterone fluctuations — ranging from 3.8 to 21.5 ng/dL — are four times more likely to report decreased libido (source: https://qa-ai.ovid.com/jnls/menopausejournal/abstract/10.1097/gme.0000000000001225~predictors-of-decreased-libido-in-women-during-the-late). In other words, it's not simply about being "low" on a lab report; the erratic ups and downs of the late perimenopausal years may be more disruptive to desire than a stable, lower baseline. This is one reason women often notice libido dips well before menopause is confirmed — the hormonal rollercoaster itself is the trigger.
There's also a structural piece that surprises many of the women I work with: without adequate oestrogen, the vagina can genuinely become shorter, narrower, and lose elasticity over time — not just drier. This is a use-it-or-lose-it tissue system. Regular blood flow to the pelvic region, whether through sexual activity, self-stimulation, or targeted pelvic floor therapy, is what keeps tissue supple and blood vessels responsive. Left unaddressed, these changes can become harder to reverse, which is why I think of vaginal health as a long-term maintenance issue, unlike hot flashes, which for many women eventually settle on their own.
And then there's the identity layer — the part clinical guides almost never mention. Menopause often coincides with an unravelling of how women see themselves: as sexual beings, as caregivers, as professionals, as partners. What I see time and again in consultations is a woman who isn't just dealing with dryness or a lower sex drive, but with a genuine sense of disconnection from her own body — as though it belongs to someone else now. That disconnection inhibits desire just as powerfully as any hormone shift, and it deserves to be named, not dismissed as "just stress."
Hormonal changes are the most common cause, but they're not the only possibility. Consider ruling out or discussing these with your GP:
Start with topical vaginal oestrogen if dryness or pain is present. This remains the gold standard for restoring local tissue health, and importantly, the FDA removed the Black Box warning for low-dose vaginal oestrogen because systemic absorption is minimal — meaning it's often safe even for women with contraindications to systemic HRT. In my practice, this single change resolves a surprising amount of secondary libido loss once pain is no longer part of the equation.
Discuss testosterone therapy with a knowledgeable provider if desire itself feels absent, not just uncomfortable. Bioidentical testosterone is increasingly used to treat Hypoactive Sexual Desire Disorder (HSDD), and given what we know about testosterone volatility driving libido loss, stabilising levels — not just raising them — can make a meaningful difference.
Commit to pelvic floor exercises, ideally guided by a pelvic health physiotherapist. Blood flow is medicine here; regular, gentle engagement improves tone, sensation, and elasticity, directly supporting the "use it or lose it" principle I mentioned earlier.
Use vaginal moisturisers and lubricants consistently, not just before intimacy. Regular use (a few times a week, separate from sexual activity) maintains tissue hydration and slows the structural narrowing that untreated dryness can cause over time.
Address the mental load explicitly, not just the hormones. Many women I see are deep in the "sandwich generation" — caring for ageing parents and children simultaneously — and this chronic stress load suppresses desire as powerfully as any hormonal shift. Naming this out loud, and actively redistributing caregiving responsibilities where possible, is genuinely therapeutic.
Consider systemic HRT if vasomotor symptoms, sleep disruption, and mood changes are significant. Systemic hormone therapy won't directly restore vaginal tissue the way topical oestrogen does, but by improving sleep and mood, it removes several major barriers to desire.
Rebuild intimacy gradually and without pressure. Secondary libido loss thrives on avoidance; gently reintroducing non-penetrative touch, and communicating openly with a partner about pain or hesitation, helps retrain the nervous system's association between intimacy and safety rather than intimacy and discomfort.
If you're unsure where to start, a structured assessment can help clarify whether your pattern looks more hormonal, structural, or psychological.

Why has my sex drive completely disappeared since starting menopause? It's usually a combination of falling and fluctuating oestrogen and testosterone affecting brain regions tied to desire, plus secondary avoidance if intimacy has become painful. Roughly 80% of women notice some decline during this transition (source: https://get.myalloy.com/symptoms/low-libido), so this is common, not a personal failing.
Can vaginal dryness actually cause a loss of sexual desire? Yes — 87% of women with vaginal dryness believe it directly contributes to reduced libido (source: https://pubmed.ncbi.nlm.nih.gov/19237616). Pain during sex teaches the brain to avoid it, creating a cycle where physical discomfort becomes psychological disinterest over time.
Is testosterone therapy safe for women to increase libido? When prescribed and monitored appropriately by a knowledgeable provider, bioidentical testosterone is increasingly used for Hypoactive Sexual Desire Disorder and is generally considered safe. It's particularly worth discussing given that testosterone fluctuations, not just low levels, strongly predict libido loss.
Does vaginal estrogen help with libido or just dryness? Primarily, it restores tissue health and reduces pain, which resolves secondary libido loss caused by avoidance. It doesn't directly boost neurobiological desire the way testosterone might, but removing pain often uncovers desire that was simply being suppressed by discomfort.
Are there non-hormonal ways to improve vaginal health and sex drive? Yes — consistent lubricant and moisturiser use, pelvic floor physiotherapy, regular blood flow to the area, stress reduction, and addressing relationship or identity concerns all help. These won't reverse significant tissue changes alone but meaningfully support comfort and connection.
Will my libido ever come back after menopause is over? For many women, yes, especially once pain, sleep, and mood are addressed. However, vaginal tissue health requires ongoing maintenance rather than a one-off treatment, so continued care is usually needed to sustain both comfort and desire long-term.
