Takes less than 2 minutes to complete 100% online

Key takeaways

• Spina bifida damages spinal nerves that control erections, causing neurogenic erectile dysfunction in many men.
• PDE5 inhibitors like sildenafil and tadalafil are first-line treatments and can help even with nerve damage.
• Always tell your prescriber about all medications, especially for bladder or bowel issues, to avoid unsafe combinations.
• If oral medicines do not work, alprostadil, vacuum devices, or specialist referral for implants are options.
• Lifestyle changes—healthy weight, stopping smoking, managing blood sugar—support erectile function and overall health.

Why Does Spina Bifida Cause Erectile Dysfunction?

Spina bifida is a condition where the spine and spinal cord do not develop properly in the womb, leaving a gap in the backbone. The level and severity of the spinal defect determine which nerves are affected. Erectile function relies on intact nerve pathways from the lower spinal cord (sacral segments S2–S4) to coordinate the relaxation of blood vessels in the penis and allow blood to flow in during arousal [1].

When spina bifida damages these sacral nerves, the brain's signals may not reach the penis effectively, and the autonomic nervous system—which controls involuntary functions like erections—can be impaired. This is known as neurogenic erectile dysfunction. The degree of ED varies: some men retain partial erectile function, while others find it difficult or impossible to achieve or maintain an erection without medical help [2].

Other factors common in spina bifida, such as reduced mobility, bladder and bowel management routines, medications (for example, some drugs for bladder spasticity), and psychological stress, can also contribute to erectile difficulties. It is important to recognise that ED in spina bifida is usually multifactorial, involving both physical nerve damage and broader health and lifestyle influences.

How Is Erectile Dysfunction Assessed in Men with Spina Bifida?

Assessment begins with a detailed medical history, including the level of your spinal lesion, any previous surgeries, current medications, and how ED affects your life and relationships. Your GP or specialist will ask about the quality of your erections, whether you have morning or spontaneous erections (which can indicate some preserved nerve function), and any other symptoms such as reduced sensation, bladder or bowel issues, or low mood [2].

A physical examination may include checking blood pressure, examining the genital area, and assessing reflexes and sensation in the lower body. Blood tests are often arranged to rule out or manage contributing conditions such as diabetes, low testosterone, or thyroid problems—all of which can worsen ED. In some cases, referral to a urologist or specialist with experience in spinal cord and neurogenic sexual dysfunction may be recommended for more detailed evaluation.

Because spina bifida can affect many body systems, your assessment may also involve discussing bladder management (as some bladder medications can influence erections), mobility aids, and any psychological support you might benefit from. A holistic approach ensures that treatment is tailored to your individual needs and that any modifiable factors—such as blood sugar control or medication adjustments—are addressed alongside ED-specific therapies.

What to Expect During Your Consultation

Whether you see your GP in person or complete an online consultation with a UK prescriber, expect questions about your general health, current medicines (including over-the-counter and herbal products), smoking, alcohol, exercise, and mental wellbeing. For men with spina bifida, it is especially important to mention any autonomic dysreflexia episodes, latex allergy (common in spina bifida), skin integrity issues, and your usual bowel and bladder routine, as these can influence treatment choices and safety. The consultation is confidential, and the aim is to find the safest and most effective option for you.

Lifestyle Measures and Self-Care for Spina Bifida and Erectile Dysfunction

While nerve damage from spina bifida cannot be reversed, several lifestyle measures can optimise your overall health and improve erectile function. Maintaining a healthy weight reduces strain on your cardiovascular system and can improve blood flow throughout the body, including to the penis. If you use a wheelchair or have limited mobility, work with a physiotherapist or occupational therapist to find exercises that suit your abilities—upper-body workouts, resistance training, and adapted cardiovascular activities all support circulation and general fitness [1].

Managing blood sugar and blood pressure is crucial, as diabetes and hypertension are more common in people with reduced mobility and can independently worsen ED. Eating a balanced diet rich in vegetables, fruits, whole grains, and lean protein, and limiting processed foods, salt, and sugar, supports vascular health. If you smoke, stopping is one of the most effective steps you can take: smoking damages blood vessels and significantly worsens erectile dysfunction [2].

Limiting alcohol is also important, as heavy drinking can impair erections and interact with ED medications. Psychological wellbeing matters too—living with spina bifida can be challenging, and anxiety or low mood can reduce libido and erectile confidence. Talking to a counsellor, joining a peer support group, or discussing concerns with your partner can all help. Open communication about sex and intimacy, including exploring different forms of closeness and pleasure, can reduce performance pressure and strengthen your relationship.

Oral Medication Options for Erectile Dysfunction in Spina Bifida

Oral medicines called phosphodiesterase type 5 (PDE5) inhibitors are the first-line treatment for erectile dysfunction in men with spina bifida, provided there are no medical reasons to avoid them [2]. These include sildenafil (Viagra), tadalafil (Cialis), vardenafil (Levitra), and avanafil (Spedra). They work by relaxing blood vessels in the penis, making it easier to achieve and maintain an erection when you are sexually aroused. They do not cause an automatic erection—sexual stimulation is still needed [3][4][5][6].

Sildenafil is usually taken about one hour before sex, with effects lasting around four to six hours. Tadalafil can be taken on-demand (at least 30 minutes before sex, with effects lasting up to 36 hours) or as a low daily dose for spontaneity. Vardenafil works similarly to sildenafil, and avanafil is the fastest-acting, often effective within 15–30 minutes. Your prescriber will help you choose based on your lifestyle, the severity of your ED, and any other health conditions or medications [11].

PDE5 inhibitors are effective in many men with neurogenic ED, though response rates can be lower than in men without nerve damage. If one medicine does not work well, trying a different PDE5 inhibitor or adjusting the dose (under medical supervision) may help. It is essential to use these medicines exactly as prescribed and to inform your prescriber of all your current medications, as some combinations are unsafe.

Important Safety Considerations

Never take PDE5 inhibitors if you use nitrates (such as GTN spray or isosorbide mononitrate for angina), nicorandil, riociguat, or recreational drugs called 'poppers', as the combination can cause a dangerous drop in blood pressure. If you take an alpha-blocker for urinary symptoms (common in spina bifida), you must be stable on that medicine and start the PDE5 inhibitor at the lowest dose, as both can lower blood pressure. Some medicines that affect liver enzymes (for example, certain antifungals, antibiotics, or HIV treatments) can alter PDE5 levels; your prescriber will check your full medication list during the consultation [3][4][5][6]. Always seek urgent medical help if you experience an erection lasting more than four hours, sudden vision or hearing loss, or chest pain during sex.

Other Treatment Options and Specialist Referrals

If oral PDE5 inhibitors are not effective, not suitable, or not tolerated, several other treatments are available. Alprostadil is a medicine that can be applied as a cream (Vitaros, applied to the tip of the penis) or given as an injection directly into the side of the penis (Caverject). Alprostadil works locally to relax blood vessels and does not rely on intact nerve pathways in the same way as PDE5 inhibitors, so it can be effective even when nerve damage is severe [7].

Vacuum erection devices (VEDs) are non-drug options that use a plastic cylinder and pump to draw blood into the penis; a constriction ring is then placed at the base to maintain the erection. VEDs can be used alongside or instead of medication and are particularly useful if you cannot take oral treatments. Some men with spina bifida may need adaptations or assistance to use a VED safely, especially if hand function or sensation is limited.

For men who do not respond to these treatments, surgical options such as penile implants may be considered. A penile prosthesis is surgically placed inside the penis and can be inflated or bent into position to allow intercourse. This is usually a last-resort option and requires referral to a specialist urological surgeon. Psychological and relationship counselling, either alone or alongside physical treatments, can also be very beneficial. Your GP or specialist can refer you to appropriate services, including psychosexual therapists experienced in working with people with disabilities.
