If your interest in sex has quietly dropped and you're wondering what happened, the honest answer is: usually several things at once. Desire in midlife is rarely about a single hormone.

The hormonal layer. Testosterone — yes, women produce it — contributes to libido, and it tapers gradually with age. Oestrogen supports the tissues and blood flow involved in arousal, and as it falls, vaginal dryness can make sex uncomfortable, which understandably dampens desire.

The everything-else layer. This is the part that gets ignored. Exhausting broken sleep, chronic stress and high cortisol, low mood, body-image shifts, relationship strain, and simply being touched-out or overloaded all suppress desire — and they're extremely common in midlife. Desire struggles when your nervous system never gets to switch off.

What helps — addressing the whole picture:

• Treat the physical barriers. If dryness or discomfort is part of it, that's very treatable (moisturisers, lubricants, local oestrogen) — and removing pain often rekindles interest.
• Protect sleep and lower stress. Desire needs spare capacity; rest and downtime are not optional extras here.
• Talk to your partner. Shifting toward unhurried, pressure-free intimacy (not just intercourse) helps many couples reconnect.
• Consider the hormonal route. For some women, HRT — and in certain cases testosterone, prescribed and monitored by a specialist — improves libido. It's worth an informed conversation.

The cause that is easy to miss: your medicine cabinet

Before assuming it must be hormones, it is worth checking what you take every day. Several common medicines can lower desire, and this is easy to overlook because the tablet was prescribed for something else entirely:

• Antidepressants, particularly SSRIs and SNRIs, are among the medicines most often linked to reduced desire and difficulty reaching orgasm. This does not mean stopping them, and you should never stop an antidepressant on your own, but a conversation about dose or an alternative is reasonable.
• Some blood pressure and heart medicines can reduce the blood flow involved in arousal.
• Spironolactone, often prescribed for acne, PCOS or blood pressure, can lower libido.
• Hormonal contraception affects some women’s desire, though the evidence across studies is genuinely mixed, so it is worth considering rather than assuming.

If the timing fits — your libido changed after starting a medication — that is a specific, answerable question for your GP or pharmacist. Our companion guide, medications that can lower libido, goes through the drug classes one by one.

Be kind to yourself. Desire that ebbs in a demanding, hormonally shifting decade isn't a flaw. With the layers addressed, it very often returns.

How to raise it with your GP

Many women never mention low desire because it feels awkward, or too minor for an appointment. It is neither. If it helps, a plain opening works best: "My sex drive has dropped and it is bothering me, and I would like to work out why." From there, it is reasonable to ask whether any of your medicines could be involved, whether your symptoms fit perimenopause, whether a blood test would help, and, if relevant, whether local oestrogen or testosterone might be options for you. You are allowed to ask for a longer appointment if you think you will need the time.

Common questions

Is low libido in midlife caused by hormones?

Partly — falling testosterone and oestrogen play a role, but sleep, stress, mood and comfort matter just as much.

Can women take testosterone for libido?

In some cases, specialists prescribe low-dose testosterone for women, with monitoring. It's an individual decision to discuss with a clinician.
