Low Libido in Perimenopause: Causes, Treatments, and What Helps
Why low libido is so common in perimenopause, what hormonal and non-hormonal treatments exist, and how relationship and body factors play a role.
Why Libido Declines During Perimenopause
Reduced libido is one of the most commonly reported but least often addressed perimenopausal symptoms. The causes are multiple and layered. Estrogen supports vaginal lubrication, blood flow to genital tissue, and tissue elasticity, all of which affect physical comfort and sensation during sex. When estrogen declines, sex can become uncomfortable or painful, which unsurprisingly reduces desire. Testosterone, which is important for libido in women as well as men, also declines with age. The ovaries and adrenal glands both produce testosterone, and output falls gradually from the mid-thirties onward. Progesterone changes during perimenopause can also dampen mood and energy, further reducing interest in sex. Fatigue from poor sleep, low mood, and increased life stressors compound the picture.
The Role of Vaginal Dryness and Pain
Vaginal dryness and discomfort during sex are among the most direct physical causes of reduced libido during perimenopause. When sex is uncomfortable or painful, the brain understandably begins to associate intimacy with discomfort, and desire decreases as a protective response. This is not a psychological weakness. It is a physiological feedback loop. Treating vaginal atrophy and dryness, whether through local (vaginal) estrogen, non-hormonal moisturisers, or lubricants, often has a notable positive effect on libido by restoring comfort. Many women who are reluctant to address libido directly find that resolving the physical discomfort dimension substantially restores their interest in sex.
Hypoactive Sexual Desire Disorder as a Clinical Diagnosis
When low libido causes significant personal distress and is not explained by another condition or relationship factor alone, it can be diagnosed as hypoactive sexual desire disorder (HSDD). HSDD is a recognised medical condition, not a personal failing. The criteria involve persistent low or absent desire for sexual activity accompanied by distress. Not every woman with reduced libido has HSDD; for some, the shift feels acceptable or even welcome. For those who are distressed by the change, HSDD is worth discussing with a GP or menopause specialist, because there are medical options. Recognising that low libido can be a clinical condition worthy of treatment rather than something to simply accept is an important step for many women.
Testosterone Therapy for Low Libido
Testosterone therapy is the most evidence-based hormonal treatment specifically for low libido in women. A systematic review including over 8,000 women found that testosterone therapy improved sexual desire, arousal, frequency of satisfying sexual activity, and orgasmic function compared to placebo. Testosterone is typically prescribed as a gel or cream, often at lower doses than those used for men, and applied to the skin daily. In the UK, testosterone is not licensed for use in women but can be prescribed off-label. Side effects at recommended doses are generally minor and reversible, including some local skin reactions and, rarely, increased facial hair. Testosterone therapy is increasingly available through NHS menopause clinics and private menopause specialists.
Non-Hormonal Options and Relationship Factors
For women who cannot or prefer not to use hormonal treatments, non-hormonal options exist. Flibanserin is a non-hormonal medication licensed for HSDD in premenopausal women in the USA, though not widely available in the UK. Beyond medication, relationship factors play a significant role. Communication with a partner about changing needs, comfort, and desires is often more impactful than any pharmacological intervention. Sex therapy or psychosexual counselling addresses the psychological and relational dimensions of low libido and is evidence-based for improving sexual satisfaction. Body image concerns, which are very common during perimenopause, also affect libido. Exercise and practices that build connection with the body, including yoga and strength training, can improve body confidence and indirectly support sexual desire.
Lifestyle Factors That Affect Desire
Sleep deprivation is one of the most underappreciated drivers of low libido. Poor sleep reduces testosterone production, lowers energy, and impairs mood, all of which decrease sexual desire. Improving sleep quality, whether through addressing night sweats with HRT or improving sleep hygiene, often has a noticeable effect on libido. Alcohol is commonly used as a social lubricant but is a depressant that reduces testosterone, impairs arousal, and worsens sleep quality. High chronic stress elevates cortisol, which suppresses sex hormone production. Exercise, particularly resistance training, supports testosterone levels and body confidence. Reducing ultra-processed food and eating adequate protein and micronutrients supports overall hormonal health. These factors will not reverse a significant hormonal libido issue on their own, but they matter and are within your control.
Seeking Help and Tracking Patterns
Low libido during perimenopause is one of the symptoms women are least likely to mention to their GP, often because they feel embarrassed or assume nothing can be done. Both assumptions are worth challenging. Treatment options exist, and clinicians who specialise in menopause are experienced in discussing sexual health without judgment. Logging your symptoms, energy levels, sleep quality, and mood alongside your cycle using an app like PeriPlan can help you see patterns and communicate the full picture of your experience to a healthcare provider. Understanding whether low libido correlates with particular cycle phases, sleep quality, or stress levels helps identify the most relevant contributing factors.
