Sexual Dysfunction: Causes, Symptoms & Treatments

at Omniya Clinic in London

Confidential, doctor-led care for women and men

Sexual difficulties are common, and in most cases, highly treatable. Whether you’re experiencing low libido, arousal changes, erectile or ejaculation problems, or pain during sex, our clinicians take a comprehensive, root-cause approach.

At Omniya Clinic in London, we assess your hormones, vascular and metabolic health, medications, sleep, stress, and relationship factors to understand what’s really going on. From there, we build a personalised treatment plan that fits your body, lifestyle, and goals.

What is Sexual Dysfunction?

Sexual dysfunction refers to ongoing difficulties with desire, arousal, orgasm, or physical comfort that cause distress or affect relationships. It can occur at any age and often has multiple contributing factors: physical, hormonal, psychological, or relational.

  • In women, sexual dysfunction may include low libido, reduced arousal or orgasm, vaginal dryness, or pain during sex. These symptoms are often linked to hormonal changes during perimenopause or menopause, as well as genitourinary and psychological factors.
  • In men, it can involve erectile dysfunction (ED), low libido, premature or delayed ejaculation, or performance-related anxiety.

 

If these symptoms persist for more than a few weeks or begin to affect your wellbeing or relationship, it’s time for a medical review. At Omniya Clinic in Knightsbridge, we take a discreet, evidence-based approach to identify and treat the underlying causes, helping you regain comfort, confidence, and sexual wellbeing.

Common Causes of Sexual Dysfunction

Sexual function depends on a balance of hormones, circulation, nerve health, mood, and relationship wellbeing. Difficulties can arise when one or more of these systems are disrupted.

  • Hormonal factors: Changes in oestrogen and progesterone during perimenopause or menopause can reduce vaginal lubrication and arousal. Low testosterone, in men and sometimes women, can lower desire and energy, while an underactive thyroid may affect mood, libido, and metabolism.
  • Vascular and metabolic factors: Conditions that affect blood flow and metabolic health, such as high blood pressure, diabetes, insulin resistance, raised cholesterol, obesity, or sleep apnoea, can interfere with arousal or erection quality.
  • Medication effects: Certain prescription medicines, including some antidepressants, antihypertensives, and hair-loss treatments, may reduce desire or make erections less reliable. A medication review can help identify and manage these effects safely.
  • Psychological and relationship factors: Stress, anxiety, low mood, body-image concerns, and relationship strain are frequent contributors. Even one difficult sexual experience can sometimes lead to performance anxiety or avoidance, which we can help you address.
  • Lifestyle factors: Poor sleep, alcohol excess, smoking, and low physical activity can all influence hormonal balance, circulation, and mood, gradually impacting sexual wellbeing.

How We Assess Sexual Dysfunction at Omniya

At Omniya Clinic in Knightsbridge, your consultation begins with a confidential, in-depth review of your symptoms, medical history, and lifestyle. Sexual dysfunction is often multifactorial, so we look at your health as a whole, not just one aspect.

Your clinician may recommend targeted investigations, only where useful, such as:

  • Blood tests: to assess your sex-hormone profile, including oestrogen and progesterone (for women) or testosterone and SHBG (for men), alongside prolactin, thyroid function, vitamin D, iron/B12, glucose or HbA1c, and lipid profile.
  • Medication and lifestyle review: exploring potential contributors such as stress, sleep patterns, physical activity, and prescribed drugs that may affect sexual function.
  • Specialist referrals (if appropriate): for pelvic, urology, or cardiovascular assessments when additional evaluation is required.

 

You’ll leave with a clear, evidence-based plan and a follow-up schedule to review progress and fine-tune results.

Treatment Options at Omniya Clinic

At Omniya Clinic in Knightsbridge, treatment plans are tailored to each individual and may combine medical therapy, lifestyle strategies, and supportive care. Our goal is to address the underlying cause, not just the symptom — improving comfort, confidence, and connection.

  • Hormone Replacement Therapy (HRT): Prescribed using body-identical oestrogen (with progesterone if you have a uterus) to reduce hot flushes, night sweats, and vaginal dryness, while improving sleep, energy, and overall wellbeing. For many women, HRT can also enhance libido directly or indirectly.
  • Local vaginal oestrogen and moisturisers: Provide targeted relief for vaginal dryness, soreness, and pain during sex, helping restore natural comfort and confidence.
  • Testosterone for women: In specialist care, low-dose testosterone may be considered for low sexual desire that persists after HRT review, when clinically appropriate.
  • Pelvic health support and sexual-wellbeing coaching: We can refer for pelvic floor physiotherapy, psychosexual therapy, or relationship support where helpful.
  • ED Medication (PDE5 inhibitors): Options such as sildenafil or tadalafil may be prescribed following medical review. These improve erectile quality and blood flow, supporting confidence and sexual function.
  • Testosterone Replacement Therapy (TRT): For men with clinically confirmed low testosterone, TRT can restore healthy levels to improve libido, energy, mood, and erectile strength.
  • Optimising cardiovascular and metabolic health: Managing blood pressure, cholesterol, glucose balance, weight, sleep, and medication side-effects is key to long-term improvement.
  • Thyroid Therapy: Supports energy, metabolism, and mood, all essential for healthy sexual function.
  • Weight-Management and Metabolic Support: Structured nutrition and activity guidance, with medical support where appropriate, can improve circulation, hormone balance, and self-confidence.
  • Hormones MOT Programme: A deeper look at sex and thyroid hormones, adrenal function, and metabolic health, with a personalised optimisation plan.
  • IV Drips: Hydration and micronutrient replenishment can complement your wider wellness and recovery plan.

Our Approach

At Omniya, we treat the cause rather than the symptom, combining medical expertise with an integrated understanding of hormones, lifestyle, and emotional wellbeing.

Our aim is to help you restore confidence, comfort, and connection — safely and sustainably.

What Treatments are Available For Sexual Dysfunction?

Sexual Dysfunction FAQs

Is Viagra the only option for erectile dysfunction (ED)?

No. Erectile dysfunction has many possible causes, including hormonal imbalance, reduced blood flow, medication side effects, and lifestyle factors. PDE5 inhibitors such as Viagra or Cialis can help, but the best results come from addressing the root causes. At Omniya Clinic, we assess hormones, cardiovascular health, and metabolic factors before recommending the safest and most effective approach.

Does HRT help with low libido?

For women, Hormone Replacement Therapy (HRT) can often improve sexual desire indirectly by easing hot flushes, sleep disturbance, and low mood. Some women also experience a direct increase in libido once hormonal balance is restored. Local vaginal oestrogen may also relieve dryness or discomfort that can make sex painful, restoring comfort and confidence.

How do you test for low testosterone?

We perform a morning blood test (when testosterone levels are highest) and may repeat it for accuracy. Diagnosis also considers symptoms such as low energy, reduced libido, and mood changes. If levels are confirmed low and treatment is appropriate, Testosterone Replacement Therapy (TRT) may be recommended, always with regular safety monitoring.

Can thyroid problems affect sexual function?

An underactive thyroid (hypothyroidism) can cause fatigue, low mood, and reduced desire, and may also affect erection quality in men.

How long until I see results?

Some people notice improvements in energy, mood, or sexual response within weeks, while deeper hormonal and metabolic changes usually take a few months. At Omniya, your clinician will review progress regularly and fine-tune your treatment plan for lasting results.
