Sexual health is an integral component of overall wellbeing, yet it remains one of the most under-discussed topics in diabetes care. Both men and women with diabetes experience a significantly higher prevalence of sexual dysfunction than the general population — a consequence of the vascular, neurological, and psychological effects of the condition. Breaking the silence on this topic is the first step towards effective management.
How Diabetes Affects Sexual Health
In men: Erectile dysfunction (ED) is the most common sexual complication of diabetes in men, affecting approximately 35–75% of men with diabetes compared to 25–30% of the general male population. The mechanisms are multifactorial: autonomic neuropathy impairs the nerve signals required for erection; endothelial dysfunction reduces nitric oxide production, impairing vasodilation; and psychological factors including depression, anxiety, and diabetes distress contribute significantly. ED in men with diabetes often occurs 10–15 years earlier than in men without diabetes and may be the first clinical sign of cardiovascular disease.
In women: Female sexual dysfunction in diabetes is less well-studied but equally prevalent. It encompasses reduced libido, impaired arousal, decreased vaginal lubrication, pain during intercourse (dyspareunia), and difficulty achieving orgasm. Autonomic neuropathy reduces genital blood flow and sensation; recurrent vaginal infections (common with poorly controlled diabetes) cause discomfort; and hormonal changes, particularly in women approaching menopause, compound these effects.
Erectile dysfunction in men with diabetes is a significant predictor of cardiovascular disease. Studies show that men with diabetes and ED have a 2–3 times higher risk of major cardiovascular events than men with diabetes without ED. If you develop ED, discuss cardiovascular risk assessment with your doctor — it may be an early warning sign that warrants further investigation.
Treatment Options
For men with ED: PDE5 inhibitors (sildenafil/Viagra, tadalafil/Cialis, vardenafil/Levitra) are effective in approximately 50–60% of men with diabetes-related ED. They are generally safe but should not be used with nitrate medications (used for angina). Vacuum erection devices, penile injections, and surgical implants are options for those who do not respond to oral medications.
For women: Vaginal lubricants and moisturisers address dryness and discomfort. Topical oestrogen (for post-menopausal women) can significantly improve vaginal atrophy and lubrication. Pelvic floor physiotherapy is effective for pain-related dysfunction. Psychological therapy and couples counselling address the relational and emotional dimensions.
For both: Optimising blood glucose control is the single most important intervention — improved glycaemic management can partially reverse neuropathic and vascular contributions to sexual dysfunction. Addressing depression and anxiety (which are both causes and consequences of sexual dysfunction) is equally important.
Sexual health should be part of your routine diabetes review. If your doctor doesn’t ask, you can raise it: “I’ve been experiencing some changes in my sexual health that I’d like to discuss.” A good diabetes team will take this seriously and either address it directly or refer you to an appropriate specialist (urologist, gynaecologist, psychosexual therapist).
Sexual dysfunction is a common, treatable complication of diabetes that deserves the same clinical attention as retinopathy or nephropathy. If you are experiencing changes in sexual health, please raise it with your diabetes care team. Effective treatments exist, and addressing this aspect of your health is an important part of comprehensive diabetes management.
