Sustained high blood glucose damages both the small blood vessels that carry blood into genital tissue and the fine nerves that carry sensation out of it, which is why diabetes affects arousal, erection, lubrication, and orgasm rather than just one of them. It also raises the rate of thrush and urinary infections, which adds pain and irritation on top. Erection difficulty in particular is common enough and early enough that it is sometimes the finding that leads to the diagnosis.

New erection difficulty with diabetes is a recognised cardiovascular marker and deserves a full risk assessment, not just a prescription.
Numbness spreading in the feet, legs, or genital area needs assessment for nerve damage.
Recurrent thrush or urinary infections can indicate glucose control that needs reviewing.
What the condition itself tends to do
Editorial categories, not percentages, and never a prediction about you. Each links to the fuller picture of that change.
Erections that are slower, softer, or do not hold. Because this depends on blood vessels and nerves, it can also be an early signal of something cardiovascular — which is why it is worth a clinical conversation rather than only a product.
Less natural lubrication, a tight or raw feeling, or discomfort that arrives during rather than before sex. Medicines cause this either by drying mucous membranes generally or by lowering oestrogen.
The body responds less, or much more slowly, even when the interest is there. Blood flow, nerve signalling, and hormone levels all feed this, and medicines can act on any of the three.
Arousal works but orgasm does not arrive. When this starts within weeks of a new medicine and had never happened before, the timing itself is information.
Wanting sex less often, or losing the spontaneous interest that used to arrive on its own. This is the effect people most often assume is psychological and most often is not only psychological.
Condition or treatment?
Diabetes rarely travels alone: most people are also on something for blood pressure and cholesterol, and some are on gabapentin or a tricyclic for nerve pain. So the sexual picture is usually the condition plus two or three medicines, and untangling them needs the whole list on the table at once rather than one drug at a time.
For almost every condition on this site, the condition and the medicines that treat it both affect sex — by different mechanisms, on different timescales, and with different answers. Being able to say which half you are asking about is the single most useful thing you can bring to an appointment, and it is the thing patients are least often given.

Never stop, pause, reduce, or change a prescribed medicine because of anything on this page. Some of the medicines listed here are dangerous to stop suddenly, and the condition being treated does not pause while you experiment. Everything here exists to make your next conversation with a prescriber more specific — not to replace it.
What helps
Glucose control is the intervention with the most evidence behind it here, and its effect on nerves and vessels is cumulative rather than immediate.
A glycerin-free water-based lubricant addresses dryness directly and does not interact with anything.
Recurrent thrush is worth treating as a glucose signal rather than only as an inconvenience.

Common questions
How does diabetes affect sex?
Sustained high blood glucose damages both the small blood vessels that carry blood into genital tissue and the fine nerves that carry sensation out of it, which is why diabetes affects arousal, erection, lubrication, and orgasm rather than just one of them. It also raises the rate of thrush and urinary infections, which adds pain and irritation on top. Erection difficulty in particular is common enough and early enough that it is sometimes the finding that leads to the diagnosis.
What are the most common sexual effects of diabetes?
The effects reported most often are difficulty getting or keeping an erection, vaginal dryness or less natural lubrication, and arousal is slower or harder to reach. Reported does not mean inevitable — the picture varies a great deal between people, and most people have more than one thing contributing at once.
Is it diabetes or the treatment for it?
Diabetes rarely travels alone: most people are also on something for blood pressure and cholesterol, and some are on gabapentin or a tricyclic for nerve pain. So the sexual picture is usually the condition plus two or three medicines, and untangling them needs the whole list on the table at once rather than one drug at a time. Timing is the most useful clue you have: an effect that appeared within weeks of starting or changing a treatment points at the treatment, while one that predates it points at the condition. Never stop, pause, or change a prescribed treatment to find out — take the timeline to the person who prescribed it.
Which treatments for diabetes have sexual side effects?
The classes commonly used here that carry documented sexual effects are statins, ace inhibitors and arbs, thiazide diuretics, beta-blockers, and gabapentin and pregabalin. Each has its own profile, so which one you are on matters — and that is a prescribing conversation, never a reason to stop anything.
What helps with the sexual effects of diabetes?
Glucose control is the intervention with the most evidence behind it here, and its effect on nerves and vessels is cumulative rather than immediate. A glycerin-free water-based lubricant addresses dryness directly and does not interact with anything. Recurrent thrush is worth treating as a glucose signal rather than only as an inconvenience.
When should I raise this with a clinician about diabetes?
Sooner than most people do, and specifically without waiting: New erection difficulty with diabetes is a recognised cardiovascular marker and deserves a full risk assessment, not just a prescription.
Educational information about what a diagnosed condition tends to do — not a diagnosis, not a way to work out whether you have something, and not advice about your treatment. Conditions on this page overlap, and most people with a long-term condition have more than one thing affecting them at once. Nothing here can examine you or run a test. Pain, bleeding, or a new and unexplained symptom always deserves assessment.
