Does cirrhosis cause erectile dysfunction? Yes, cirrhosis can cause erectile dysfunction (ED), and this connection is well-established in medical literature. Men with cirrhosis experience ED more frequently than the general population, with severity often correlating with disease progression. The relationship is multifactorial, involving hormonal imbalances, vascular changes, neurological complications, and psychological factors. Cirrhosis disrupts hormone metabolism, protein production, and blood flow—all essential for healthy erectile function. Recognising this link enables healthcare professionals to address sexual health as an integral part of cirrhosis care, ensuring comprehensive assessment and appropriate management tailored to individual needs.

Does Cirrhosis Cause Erectile Dysfunction?

Yes, cirrhosis can cause erectile dysfunction (ED), and the relationship between these conditions is well-established in medical literature. Studies indicate that a significant proportion of men with cirrhosis experience erectile dysfunction, making it more common than in the general population. The severity of ED often correlates with the progression of liver disease, with more advanced cirrhosis typically associated with greater sexual dysfunction.

The connection between cirrhosis and erectile dysfunction is multifactorial, involving complex interactions between hormonal imbalances, vascular changes, psychological factors, and the direct effects of liver disease on multiple body systems. Cirrhosis disrupts the liver's ability to metabolise hormones, produce essential proteins, and maintain normal blood flow, all of which are crucial for healthy erectile function. Additionally, the accumulation of toxins that would normally be processed by a healthy liver can affect nerve function and blood vessel health.

It is important to recognise that whilst cirrhosis is a significant risk factor for ED, other contributing factors may coexist. These include diabetes, cardiovascular disease, alcohol use, medications, and psychological stress—all of which are common in patients with chronic liver disease. The presence of erectile dysfunction in a man with cirrhosis should prompt a comprehensive medical assessment to identify all contributing factors and guide appropriate management. This should include assessment of cardiometabolic risk factors (blood pressure, cholesterol, blood glucose) as ED can be an early marker of cardiovascular disease. Understanding this connection helps patients and healthcare professionals address sexual health concerns as an integral part of cirrhosis care, rather than viewing it as an isolated or inevitable consequence of ageing.

How Liver Cirrhosis Affects Sexual Function

Cirrhosis impacts sexual function through several interconnected physiological mechanisms. The liver plays a central role in maintaining vascular health, and cirrhosis-related changes can impair erectile function. The systemic haemodynamic changes and endothelial dysfunction (damage to the inner lining of blood vessels) associated with cirrhosis affect the vascular responses necessary for achieving and maintaining an erection. Portal hypertension, a hallmark of advanced cirrhosis, contributes to these systemic circulatory changes that can ultimately impact erectile tissue function.

Neurological complications of cirrhosis further contribute to erectile dysfunction. Hepatic encephalopathy, caused by the accumulation of toxins such as ammonia, can affect the nervous system's ability to transmit the signals necessary for sexual arousal and response. Peripheral neuropathy, which may develop in patients with cirrhosis (particularly those with alcohol-related liver disease), can damage the nerves that control erection, leading to reduced sensation and impaired erectile function.

The psychological burden of living with chronic liver disease cannot be underestimated. Depression, anxiety, and reduced self-esteem are prevalent among men with cirrhosis and are independent risk factors for erectile dysfunction. Fatigue, a near-universal symptom of cirrhosis, significantly reduces libido and sexual activity. Body image concerns related to ascites, muscle wasting, gynaecomastia, or jaundice may further diminish sexual confidence and desire.

Medications commonly prescribed for cirrhosis complications can also affect sexual function. Diuretics such as spironolactone, used to manage ascites and oedema, have anti-androgenic effects that can worsen erectile dysfunction. Beta-blockers, prescribed for portal hypertension, may reduce libido and erectile capacity. Other medications sometimes used in this patient population, such as certain antidepressants or opioid analgesics, can also contribute to sexual dysfunction. Recognising these multiple pathways helps clinicians develop comprehensive management strategies that address the full spectrum of factors affecting sexual health in cirrhosis patients.

Hormonal Changes in Cirrhosis and Erectile Problems

Hormonal dysregulation is one of the most significant mechanisms linking cirrhosis to erectile dysfunction. The liver is essential for metabolising sex hormones, and when cirrhotic liver tissue replaces healthy hepatocytes, this function becomes severely impaired. Men with cirrhosis typically experience reduced testosterone levels (hypogonadism) alongside elevated oestrogen levels, creating a hormonal imbalance that profoundly affects sexual function. A substantial proportion of men with cirrhosis have low testosterone, which directly correlates with reduced libido, erectile dysfunction, and decreased sexual satisfaction.

The mechanism behind these hormonal changes involves several processes. Cirrhosis increases the activity of aromatase, an enzyme that converts testosterone to oestradiol (a form of oestrogen). Simultaneously, the damaged liver cannot adequately clear oestrogen from the circulation, leading to oestrogen accumulation. This relative excess of oestrogen compared to testosterone contributes not only to erectile dysfunction but also to feminising features such as gynaecomastia (breast tissue enlargement), testicular atrophy, and altered body hair distribution.

The hypothalamic-pituitary-gonadal axis is also disrupted in cirrhosis. Chronic illness, malnutrition, and inflammatory cytokines associated with liver disease suppress the release of gonadotropin-releasing hormone (GnRH) from the hypothalamus and luteinising hormone (LH) from the pituitary gland. This results in reduced stimulation of testicular testosterone production. Additionally, sex hormone-binding globulin (SHBG) levels are often elevated in cirrhosis, which binds to available testosterone and reduces the amount of free, biologically active hormone.

Alcohol-related cirrhosis presents additional hormonal challenges. Alcohol has direct toxic effects on testicular Leydig cells, which produce testosterone, further exacerbating hypogonadism. Even after alcohol cessation, these hormonal abnormalities may persist, though some improvement is possible with sustained abstinence and liver function stabilisation. Hormonal assessment should be considered in men with cirrhosis experiencing erectile dysfunction. In line with UK practice, testosterone should be measured in the morning (around 9 am) on at least two separate occasions. If SHBG is elevated, as often occurs in cirrhosis, assessment of free or bioavailable testosterone may be necessary to accurately evaluate hormonal status.

Treatment Options for Erectile Dysfunction with Cirrhosis

Managing erectile dysfunction in men with cirrhosis requires a tailored, multidisciplinary approach that considers the severity of liver disease, contributing factors, and patient safety. Treatment should always begin with addressing modifiable risk factors and optimising management of the underlying liver condition. For patients with alcohol-related cirrhosis, sustained abstinence is paramount, as it may improve both liver function and hormonal balance over time. Nutritional support to address deficiencies common in cirrhosis can also contribute to improved overall health and sexual function.

Phosphodiesterase type 5 (PDE5) inhibitors, such as sildenafil, tadalafil, and vardenafil, are first-line pharmacological treatments for erectile dysfunction and can be effective in men with cirrhosis. However, their use requires careful consideration of liver function. In patients with Child-Pugh class A cirrhosis (compensated disease), these medications can generally be used with dose adjustments. For those with Child-Pugh class B or C cirrhosis (decompensated disease), PDE5 inhibitors should be used with extreme caution, with drug-specific recommendations: sildenafil should start at a reduced dose of 25 mg in hepatic impairment; tadalafil and avanafil are not recommended in severe hepatic impairment; vardenafil is contraindicated in severe hepatic impairment.

All PDE5 inhibitors are absolutely contraindicated in patients taking nitrates or riociguat due to the risk of severe hypotension. Caution is also needed with alpha-blockers, and strong CYP3A4 inhibitors (such as ritonavir, ketoconazole, or erythromycin) may significantly increase PDE5 inhibitor levels. Grapefruit juice should also be avoided. Blood pressure should be checked before starting treatment, particularly in patients on non-selective beta-blockers for portal hypertension.

Medication review is essential, as some drugs used in cirrhosis management contribute to erectile dysfunction. If spironolactone is implicated, switching to alternative diuretics may be considered, though this decision must be specialist-led and balance the management of ascites and oedema. Similarly, if beta-blockers are affecting sexual function, discussion with a hepatologist about alternative strategies for managing portal hypertension may be appropriate, though this must not compromise variceal bleeding prevention.

Testosterone replacement therapy (TRT) may be considered in men with confirmed hypogonadism and cirrhosis, but requires specialist endocrinology input. Transdermal or intramuscular preparations are preferred over oral formulations. Monitoring should include prostate-specific antigen (PSA), haematocrit, liver function tests, and fluid status. TRT is contraindicated in prostate cancer, male breast cancer, polycythaemia, and uncontrolled heart failure. Psychological support, including counselling or cognitive behavioural therapy for depression and anxiety, addresses important non-physical contributors to erectile dysfunction and should be integrated into comprehensive care. Patients should only obtain ED medicines from regulated UK pharmacies or services, avoiding unregulated online sources.

When to Seek Medical Advice

Men with cirrhosis experiencing erectile dysfunction should discuss this with their GP or hepatologist rather than attempting self-management. Sexual dysfunction is a legitimate medical concern that warrants professional assessment, and healthcare providers are accustomed to discussing these issues sensitively. Early consultation allows for identification of treatable contributing factors and prevents the use of potentially unsafe treatments purchased online or from unregulated sources, which may be particularly dangerous for individuals with liver disease.

Seek medical advice promptly if erectile dysfunction:

• Develops suddenly or worsens rapidly, as this may indicate progression of liver disease or development of new complications

• Is accompanied by other new symptoms such as increased fatigue, confusion, abdominal swelling, or jaundice

• Significantly affects quality of life, relationships, or psychological wellbeing

• Occurs alongside reduced libido, testicular pain, or breast enlargement, which may indicate hormonal imbalances requiring investigation

• Is associated with penile deformity or curvature (possible Peyronie's disease)

• Persists despite first-line treatments, particularly in men under 40 with severe ED

Urgent medical attention is required if you experience:

• A prolonged erection lasting more than four hours (priapism), which is a medical emergency

• Chest pain, severe dizziness, or fainting after taking any erectile dysfunction medication

• Signs of liver decompensation, including worsening confusion, increased abdominal swelling, vomiting blood, or black tarry stools

Your healthcare team can arrange appropriate investigations, which may include blood tests to assess liver function, hormone levels (morning testosterone measured on two occasions), and other factors such as diabetes or thyroid function. A cardiometabolic risk assessment (blood pressure, cholesterol, blood glucose) is also important as ED can be an early marker of cardiovascular disease. They can also review your current medications and discuss safe treatment options tailored to your degree of liver impairment. Remember that erectile dysfunction is common in cirrhosis and discussing it openly with your medical team is an important step towards finding effective management strategies whilst ensuring your overall safety. If you experience any suspected side effects from medications, report them through the MHRA Yellow Card Scheme (yellowcard.mhra.gov.uk). NICE guidance emphasises the importance of addressing quality of life issues, including sexual health, as part of comprehensive chronic disease management.
