Does bladder cancer cause erectile dysfunction? Whilst bladder cancer itself rarely directly causes erectile dysfunction (ED), the connection between these conditions is significant and multifaceted. The anatomical proximity of the bladder to structures controlling erectile function means that advanced disease and, more commonly, bladder cancer treatments—particularly radical cystectomy—can substantially impact sexual health. Psychological factors following cancer diagnosis, shared risk factors such as smoking and vascular disease, and treatment-related nerve or blood vessel damage all contribute to ED in bladder cancer patients. Understanding this complex relationship enables men and their healthcare teams to address sexual health concerns proactively throughout the cancer journey.

Understanding the Link Between Bladder Cancer and Erectile Dysfunction

Bladder cancer and erectile dysfunction (ED) can be connected, though the relationship is complex and multifaceted. Erectile dysfunction—the persistent inability to achieve or maintain an erection sufficient for satisfactory sexual activity—is not directly caused by bladder cancer in most cases. However, the anatomical proximity of the bladder to structures involved in erectile function means that both the disease and its treatment can significantly impact sexual health.

The bladder sits close to the prostate gland, seminal vesicles, and neurovascular bundles that control erectile function. Advanced bladder cancer that invades beyond the bladder wall may affect these neighbouring structures, potentially interfering with the nerves and blood vessels essential for achieving and maintaining an erection. However, localised bladder cancer confined to the bladder lining typically does not directly impair erectile function through mechanical means.

Psychological factors also play a substantial role in the connection between bladder cancer and ED. A cancer diagnosis often triggers significant emotional distress, anxiety, and depression—all of which are recognised contributors to erectile dysfunction. The stress of managing a serious illness, concerns about prognosis, and changes to body image can profoundly affect sexual desire and performance.

It's worth noting that bladder cancer and erectile dysfunction share several risk factors, including advancing age, smoking, and vascular disease. These underlying factors may contribute to ED independently of the cancer itself. Additionally, general health decline associated with cancer, including fatigue, pain, and the side effects of various treatments, can indirectly contribute to sexual dysfunction. Understanding these interconnected factors is essential for patients and healthcare professionals when addressing sexual health concerns in the context of bladder cancer.

How Bladder Cancer Treatment Affects Sexual Function

Treatment modalities for bladder cancer vary depending on the stage and grade of disease, and each approach carries different implications for sexual function. The most significant impact on erectile function typically occurs with radical cystectomy—surgical removal of the bladder—which is the standard treatment for muscle-invasive bladder cancer.

During radical cystectomy in men, the procedure often involves removing the bladder, prostate, seminal vesicles, and surrounding lymph nodes. This extensive surgery carries a high risk of damaging the cavernosal nerves that run alongside the prostate and are crucial for erectile function. Even with nerve-sparing surgical techniques, which aim to preserve these delicate neurovascular bundles, erectile dysfunction remains a common outcome. Studies suggest that 50-90% of men experience some degree of ED following radical cystectomy, with rates varying based on surgical technique, surgeon experience, and patient age.

It's important to note that cystoprostatectomy also results in dry orgasm (anejaculation) and infertility, as the prostate and seminal vesicles are removed. Men who wish to father children should discuss fertility preservation options before treatment begins.

Radiotherapy, used either as primary treatment or in combination with chemotherapy, can also affect erectile function. Radiation to the pelvic region may damage blood vessels and nerves over time, with erectile dysfunction sometimes developing months or even years after treatment completion. The risk increases with higher radiation doses and larger treatment fields.

Intravesical therapies, such as BCG (Bacillus Calmette-Guérin) immunotherapy for non-muscle-invasive bladder cancer, generally have minimal direct impact on erectile function as they are administered locally into the bladder. However, patients should use condoms during sexual intercourse for at least one week after BCG treatment and follow their healthcare team's specific advice regarding sexual activity. Systemic chemotherapy can cause fatigue and peripheral neuropathy that may indirectly affect sexual function, though the evidence for chemotherapy directly reducing testosterone levels in bladder cancer patients is limited and varies by treatment regimen.

Managing Erectile Dysfunction After Bladder Cancer Diagnosis

Addressing erectile dysfunction following bladder cancer requires a comprehensive, multidisciplinary approach that considers both physical and psychological aspects of sexual health. Early intervention and open communication with healthcare professionals are crucial for optimal outcomes.

Psychological support forms a cornerstone of ED management in cancer patients. Counselling or psychosexual therapy can help patients and their partners navigate the emotional challenges associated with cancer diagnosis and treatment. Cognitive behavioural therapy (CBT) has demonstrated effectiveness in addressing anxiety and depression that contribute to sexual dysfunction. Many NHS cancer centres offer specialist psychosexual counselling services, and patients should enquire about these resources early in their treatment journey.

Penile rehabilitation programmes are increasingly offered following pelvic surgery, though the evidence base remains variable. These programmes typically involve early use of erectile aids to maintain penile oxygenation and prevent tissue fibrosis during the recovery period. The rationale is that regular erectile activity—whether spontaneous or medically induced—helps preserve the structural integrity of penile tissue, though treatment plans should be individualised.

Lifestyle modifications can also support sexual health recovery. These include:

• Maintaining cardiovascular fitness through regular exercise

• Achieving and maintaining a healthy weight

• Limiting alcohol consumption

• Stopping smoking, which impairs blood flow

• Managing other health conditions such as diabetes and hypertension

It's worth noting that erectile dysfunction can sometimes signal underlying cardiovascular disease. Men with persistent ED should have their blood pressure, cholesterol, and blood glucose checked, particularly if they have other risk factors.

Open communication with partners is equally vital. Couples counselling can help both individuals adjust to changes in sexual function and explore alternative forms of intimacy. Many men and their partners find that redefining sexual satisfaction beyond penetrative intercourse reduces performance anxiety and enhances overall relationship satisfaction.

Treatment Options for ED Related to Bladder Cancer

Several evidence-based treatment options exist for managing erectile dysfunction following bladder cancer treatment, with choice depending on individual circumstances, treatment history, and patient preference.

Phosphodiesterase type 5 (PDE5) inhibitors are typically the first-line pharmacological treatment for ED. These medications—including sildenafil, tadalafil, and vardenafil—work by enhancing the natural erectile response to sexual stimulation by increasing blood flow to the penis. They require sexual stimulation to work and are typically taken 30-60 minutes before sexual activity. Following nerve-sparing surgery, success rates vary but can reach 40-60% with regular use.

Generic sildenafil can be prescribed on the NHS for any man with ED. Other PDE5 inhibitors may have restricted NHS availability. Sildenafil 50mg is also available without prescription from pharmacists (as Viagra Connect) following an assessment. PDE5 inhibitors are contraindicated in men taking nitrate medications or riociguat, and caution is needed with alpha-blockers, certain antihypertensives, and in men with unstable cardiovascular disease. Common side effects include headache, flushing, and indigestion. Patients should seek urgent medical attention for erections lasting over 4 hours, sudden vision/hearing loss, or chest pain.

For men who do not respond adequately to oral medications, intracavernosal injections offer an alternative. These involve self-injecting vasoactive drugs (such as alprostadil) directly into the penis, producing an erection within 5-20 minutes regardless of nerve function. Whilst the concept may initially seem daunting, most men become comfortable with the technique after proper training. Success rates are high (70-80%), though potential side effects include penile pain, priapism (prolonged erection), and fibrosis with long-term use. Injection sites should be rotated, and men on anticoagulants should use with caution.

Vacuum erection devices (VEDs) provide a non-pharmacological option. These mechanical pumps create negative pressure around the penis, drawing blood into the erectile tissue, with a constriction ring then placed at the base to maintain the erection. VEDs are safe, non-invasive, and can be used regardless of nerve damage. The constriction ring should not be left in place for more than 30 minutes, and men with bleeding disorders or on anticoagulants should use with caution.

Penile prosthesis implantation represents the most invasive but also most reliable treatment option. Surgical implants—either malleable or inflatable—provide a permanent solution with high satisfaction rates (typically >80%) among both patients and partners. This option is generally reserved for men who have not responded to less invasive treatments. Potential complications include infection and mechanical failure. Referral to a specialist urologist with expertise in prosthetic surgery is necessary, and waiting times can vary across NHS trusts.

Patients who experience suspected side effects from any ED treatment should report them through the MHRA Yellow Card Scheme (yellowcard.mhra.gov.uk).

When to Seek Medical Advice About Sexual Health Concerns

Patients should feel empowered to discuss sexual health concerns with their healthcare team at any point during their bladder cancer journey. Unfortunately, sexual dysfunction remains an under-discussed topic in oncology settings, with many patients reluctant to raise concerns and clinicians sometimes failing to proactively address the issue.

Ideally, discussions about potential sexual side effects should occur before treatment begins. This allows patients to make informed decisions about treatment options where choices exist and to have realistic expectations about recovery. Pre-treatment counselling also provides an opportunity to discuss fertility preservation if relevant and to establish baseline sexual function.

Patients should contact their GP or specialist team if they experience:

• Persistent erectile difficulties lasting more than a few weeks

• Significant distress or relationship problems related to sexual dysfunction

• Loss of libido or other changes in sexual desire

• Pain during sexual activity

• Psychological symptoms such as anxiety or depression affecting quality of life

People with unstable cardiac symptoms or who have recently experienced a heart attack or stroke should seek medical advice before using ED medicines or resuming sexual activity.

Urgent medical attention is required if priapism (an erection lasting more than four hours) occurs, particularly in men using intracavernosal injections or other erectile aids, as this constitutes a medical emergency requiring immediate treatment to prevent permanent damage.

Patients receiving BCG treatment should contact their healthcare team urgently if they develop a high fever (≥38.5°C), flu-like symptoms, or other concerning symptoms after treatment, and should follow their team's specific advice about sexual activity precautions.

Most NHS cancer centres have specialist nurses who can provide initial advice and arrange appropriate referrals. Urology departments typically offer dedicated erectile dysfunction clinics, and some centres have psychosexual counsellors integrated into cancer care pathways. Private treatment is also available for those who prefer this route or face long NHS waiting times.

It is worth noting that sexual health is an important component of overall quality of life and cancer survivorship. Healthcare professionals increasingly recognise that addressing these concerns is not merely about restoring erectile function but about supporting holistic wellbeing, relationship health, and psychological adjustment following cancer treatment. Patients should never feel that sexual health concerns are trivial or inappropriate to discuss—they are a legitimate and important aspect of cancer care.
