Does peroxide help with erectile dysfunction? This question arises from online claims suggesting hydrogen peroxide might improve erectile function. However, there is no credible scientific evidence or UK regulatory approval supporting hydrogen peroxide as a treatment for erectile dysfunction. In fact, using hydrogen peroxide for this purpose poses serious health risks, including chemical burns and tissue damage. Erectile dysfunction is a medical condition requiring proper assessment and evidence-based treatment. This article examines the lack of evidence for hydrogen peroxide, explains proven treatments available through the NHS, and outlines when to seek medical advice.
Summary: No, hydrogen peroxide does not help with erectile dysfunction and poses serious health risks including chemical burns and tissue damage.
- Hydrogen peroxide has no UK regulatory approval (MHRA) or clinical evidence supporting its use for erectile dysfunction.
- First-line ED treatments are PDE5 inhibitors (sildenafil, tadalafil, vardenafil, avanafil) which enhance nitric oxide pathways.
- Applying or ingesting hydrogen peroxide for ED can cause chemical burns, urethral injury, systemic toxicity, and infection.
- Erectile dysfunction often signals underlying cardiovascular disease or diabetes requiring proper medical evaluation.
- Men experiencing persistent ED should consult their GP for evidence-based assessment and treatment options.
- PDE5 inhibitors must not be used with nitrates, nicorandil, or riociguat due to dangerous blood pressure interactions.

What Is Hydrogen Peroxide and How Does It Work in the Body?
Hydrogen peroxide (H₂O₂) is a chemical compound consisting of two hydrogen atoms and two oxygen atoms. It exists naturally in the body at very low concentrations as a byproduct of cellular metabolism, particularly within mitochondria and peroxisomes. At physiological levels, hydrogen peroxide functions as a signalling molecule involved in various cellular processes, including immune responses and wound healing.
In clinical settings, hydrogen peroxide has historically been used as a topical antiseptic. However, current NHS guidance does not recommend routine use of hydrogen peroxide or other antiseptics for cleaning minor wounds, as they may delay healing. Simple irrigation with clean water is preferred for most minor cuts and grazes. Medical-grade hydrogen peroxide solutions (typically 3% for household use) are available, whilst industrial formulations can be significantly stronger and are hazardous. When applied to tissues, hydrogen peroxide releases oxygen through enzymatic breakdown by catalase, creating a foaming action.
Within the body, hydrogen peroxide is tightly regulated by antioxidant enzymes such as catalase, glutathione peroxidase, and peroxiredoxins. These enzymes prevent excessive accumulation, which could otherwise cause oxidative stress and cellular damage. Oxidative stress occurs when there is an imbalance between reactive oxygen species (including hydrogen peroxide) and the body's antioxidant defences, potentially damaging proteins, lipids, and DNA.
Whilst hydrogen peroxide plays legitimate physiological roles at controlled concentrations, there is no established medical use for hydrogen peroxide in treating erectile dysfunction. The compound's presence in the body relates to cellular metabolism and immune function rather than vascular or erectile mechanisms. Any claims suggesting hydrogen peroxide as a treatment for erectile dysfunction lack scientific foundation and regulatory approval from the MHRA (Medicines and Healthcare products Regulatory Agency). No hydrogen peroxide product holds a UK marketing authorisation for erectile dysfunction.
Does Peroxide Help with Erectile Dysfunction?
There is no credible scientific evidence or UK regulatory approval for hydrogen peroxide in the treatment of erectile dysfunction. Erectile dysfunction (ED) is a complex medical condition involving vascular, neurological, hormonal, and psychological factors. Effective treatments target specific physiological mechanisms—primarily enhancing blood flow to the penis through well-understood pharmacological pathways.
Some unsubstantiated online claims suggest that hydrogen peroxide might improve erectile function by increasing oxygen delivery to tissues or reducing oxidative stress. However, these assertions are not supported by peer-reviewed research, clinical trials, or regulatory approval. In fact, the relationship between oxidative stress and erectile dysfunction is more nuanced: whilst excessive oxidative stress can impair endothelial function and contribute to ED, introducing hydrogen peroxide—a reactive oxygen species itself—would likely exacerbate rather than alleviate oxidative damage.
Erectile function depends primarily on the nitric oxide pathway, which relaxes smooth muscle in penile blood vessels, allowing increased blood flow. Licensed medications for ED, such as phosphodiesterase type 5 (PDE5) inhibitors, work by enhancing this natural mechanism. Hydrogen peroxide does not interact with this pathway in any therapeutically beneficial manner.
No formulation of hydrogen peroxide has received approval from the MHRA or been recommended by NICE (National Institute for Health and Care Excellence) for erectile dysfunction. Healthcare professionals in the UK follow evidence-based guidelines that do not include hydrogen peroxide in any capacity for managing ED. Do not apply, inject, or ingest hydrogen peroxide for erectile dysfunction. Patients considering any treatment for erectile dysfunction should consult their GP rather than experimenting with unproven substances that may pose serious health risks.
Evidence-Based Treatments for Erectile Dysfunction in the UK
The NHS and NICE provide clear, evidence-based guidance on managing erectile dysfunction, with treatment options tailored to underlying causes and individual patient circumstances. First-line pharmacological treatment typically involves PDE5 inhibitors, including sildenafil (Viagra), tadalafil (Cialis), vardenafil (Levitra), and avanafil (Spedra). These medications enhance the effects of nitric oxide, promoting smooth muscle relaxation and increased blood flow to the penis during sexual stimulation.
Important safety information for PDE5 inhibitors:
-
Do not use if you take nitrates (e.g., glyceryl trinitrate for angina), nicorandil, or riociguat—the combination can cause dangerous drops in blood pressure
-
Use with caution if you take alpha-blockers for prostate problems or high blood pressure; your doctor will advise on timing and dosing
-
Avoid if you have significant cardiovascular disease, recent stroke or heart attack, severe liver impairment, or certain eye conditions (e.g., non-arteritic anterior ischaemic optic neuropathy)
-
Common side effects include headache, facial flushing, indigestion, and nasal congestion
-
Seek urgent medical attention if you experience an erection lasting more than 4 hours (priapism), sudden vision or hearing loss, or chest pain during sexual activity
If you experience side effects from any medicine, you can report them via the MHRA Yellow Card scheme at yellowcard.mhra.gov.uk.
Before prescribing medication, GPs conduct a thorough assessment to identify potential underlying causes. This may include:
-
Cardiovascular evaluation – ED can be an early indicator of cardiovascular disease; formal cardiovascular risk assessment (e.g., QRISK3) and management of modifiable risk factors are essential
-
Hormonal assessment – measuring morning (around 9am) total testosterone levels on two separate occasions, particularly if accompanied by reduced libido; if low, further tests (LH, FSH, prolactin) and possible endocrinology referral
-
Diabetes screening – poorly controlled diabetes commonly contributes to ED
-
Medication review – certain drugs (antihypertensives, antidepressants) may cause or worsen ED
-
Psychological factors – anxiety, depression, and relationship issues frequently contribute
For men who cannot use or do not respond to oral medications, second-line treatments include vacuum erection devices, intracavernosal injections (alprostadil), or intraurethral alprostadil. In select cases, surgical options such as penile prosthesis implantation may be considered. Referral to specialist services—urology (for structural penile disease, Peyronie's disease, or refractory ED), endocrinology (for confirmed hypogonadism), cardiology (for symptoms or high cardiovascular risk), or psychosexual medicine—may be appropriate.
Lifestyle modifications form an essential component of ED management. NICE guidance emphasises the importance of regular physical activity, maintaining a healthy weight, reducing alcohol consumption, stopping smoking, and managing stress. These interventions address modifiable risk factors and often improve erectile function alongside medical treatments. Psychological interventions, including cognitive behavioural therapy or psychosexual counselling, benefit men where psychological factors predominate.
Risks of Using Hydrogen Peroxide for Erectile Dysfunction
Using hydrogen peroxide for erectile dysfunction poses significant health risks with no potential benefit. Topical or internal application of hydrogen peroxide to genital tissues is dangerous and can cause severe chemical burns, tissue damage, and scarring. The delicate mucous membranes of the penis and urethra are particularly vulnerable to chemical injury from oxidising agents like hydrogen peroxide.
Potential complications from inappropriate hydrogen peroxide use include:
-
Chemical burns and tissue necrosis – causing pain, scarring, and potentially permanent damage
-
Urethral injury – if introduced into the urethra, leading to strictures or infection
-
Systemic toxicity – if absorbed or ingested in significant quantities, potentially causing gastrointestinal irritation, vomiting, gas embolism (if oxygen bubbles enter the bloodstream), or corrosive injury to the gastrointestinal tract
-
Infection risk – damaged tissue becomes more susceptible to bacterial or fungal infections
-
Delayed appropriate treatment – relying on ineffective remedies postpones evidence-based medical care
Hydrogen peroxide is not licensed for internal use in the UK, and ingestion is dangerous. Do not swallow or instil hydrogen peroxide. There is no approved hydrogen peroxide treatment for erectile dysfunction. If you have ingested hydrogen peroxide or experienced genital chemical burns or exposure, contact NHS 111 for urgent advice. Call 999 or go to A&E if you experience severe pain, breathing difficulty, vomiting, neurological symptoms, or have been exposed to large amounts or high-concentration solutions.
Erectile dysfunction often signals underlying health conditions such as cardiovascular disease or diabetes that require proper medical evaluation. Attempting self-treatment with unproven substances not only risks direct harm but may also delay diagnosis of serious conditions. The psychological impact of ED can be significant, and ineffective treatments may worsen anxiety and relationship difficulties.
Patients should be aware that legitimate ED treatments undergo rigorous clinical trials and regulatory scrutiny before approval. The absence of any such evidence for hydrogen peroxide reflects not a gap in research but rather the lack of any plausible therapeutic mechanism or safety profile for this application.
When to See a GP About Erectile Dysfunction
Men experiencing erectile dysfunction should consult their GP, particularly if the problem is persistent, worsening, or causing distress. ED is not simply a normal part of ageing and often indicates underlying health issues that benefit from early intervention. A GP consultation provides opportunity for proper assessment, identification of contributing factors, and access to effective, safe treatments.
Seek medical advice if you experience:
-
Consistent difficulty achieving or maintaining erections sufficient for sexual activity
-
Sudden onset of ED, which may indicate vascular or neurological problems
-
ED accompanied by other symptoms such as chest pain, breathlessness, or leg pain during exercise
-
Reduced libido alongside erectile difficulties, potentially suggesting hormonal issues
-
Psychological distress, anxiety, or relationship problems related to sexual function
-
Morning erections have ceased, which may help distinguish physical from psychological causes
Call 999 or go to A&E immediately if erectile dysfunction occurs alongside chest pain during sexual activity, as this may indicate significant cardiovascular disease requiring urgent assessment. Also seek emergency care if you feel severely unwell.
During the consultation, your GP will take a comprehensive medical and sexual history, review current medications, and may perform a physical examination. Blood tests might be arranged to check for diabetes, cardiovascular risk factors, and hormone levels (including morning testosterone on two occasions if low libido is present; further endocrine tests and possible referral if confirmed low). Cardiovascular risk assessment (e.g., QRISK3) and management of modifiable risks are important components of care. This assessment is confidential, and GPs are experienced in discussing sexual health sensitively.
Many men feel embarrassed discussing erectile dysfunction, but healthcare professionals regard it as a common medical condition warranting the same professional approach as any other health concern. Early consultation enables prompt treatment and may identify serious conditions such as diabetes or cardiovascular disease at a stage when intervention is most effective. The NHS provides various treatment options, and GPs can refer to specialist services when appropriate, including urology, endocrinology, cardiology, or psychosexual medicine clinics. Effective, evidence-based help is available—self-treatment with unproven or dangerous substances like hydrogen peroxide is never advisable.
Frequently Asked Questions
Can hydrogen peroxide treat erectile dysfunction?
No, hydrogen peroxide cannot treat erectile dysfunction and has no UK regulatory approval or clinical evidence supporting this use. Using hydrogen peroxide for ED poses serious health risks including chemical burns, tissue damage, and systemic toxicity, whilst providing no therapeutic benefit.
What are the safest treatments for erectile dysfunction available on the NHS?
The safest first-line treatments are PDE5 inhibitors such as sildenafil (Viagra), tadalafil (Cialis), vardenafil (Levitra), and avanafil (Spedra), which are prescribed after proper medical assessment. These medications enhance natural nitric oxide pathways to improve blood flow to the penis during sexual stimulation.
Why do some people think peroxide might help with ED?
Unsubstantiated online claims suggest hydrogen peroxide might increase oxygen delivery or reduce oxidative stress, but these assertions lack peer-reviewed research or clinical trial evidence. In reality, hydrogen peroxide is itself a reactive oxygen species that would likely worsen rather than improve oxidative damage affecting erectile function.
What happens if I use hydrogen peroxide on my genitals?
Applying hydrogen peroxide to genital tissues can cause severe chemical burns, tissue necrosis, urethral injury, scarring, and increased infection risk. If you have experienced genital chemical exposure, contact NHS 111 for urgent advice, or call 999 if you have severe pain, breathing difficulty, or neurological symptoms.
Can I take Viagra if I'm on blood pressure medication?
PDE5 inhibitors like Viagra must never be taken with nitrates, nicorandil, or riociguat due to dangerous blood pressure drops. If you take alpha-blockers for blood pressure or prostate problems, your GP will advise on safe timing and dosing, as these medications require careful management when used together.
When should I see my GP about erectile problems?
Consult your GP if you experience consistent difficulty achieving or maintaining erections, sudden onset ED, reduced libido, or psychological distress related to sexual function. Early consultation enables proper assessment, identification of underlying conditions like cardiovascular disease or diabetes, and access to effective NHS treatments.
