Erectile Dysfunction (ED): Causes, Symptoms, Diagnosis and Treatment

Erectile dysfunction (ED), commonly called impotence, refers to the persistent or recurrent inability to achieve or maintain a penile erection that allows satisfactory sexual activity. Almost every man experiences occasional difficulty getting an erection at some point. However, repeated or persistent erectile problems can indicate an underlying medical, vascular, hormonal, psychological, or lifestyle-related condition.

ED can affect men at different ages and can significantly affect confidence, relationships, and quality of life. Erectile dysfunction does not represent a normal part of ageing. In many cases, doctors can identify and treat the underlying cause and improve erectile function.

At Jyoti Hospital, Gurugram, our urology team evaluates erectile dysfunction comprehensively. We identify possible causes and recommend treatment according to each patient’s health, symptoms, expectations, and treatment goals.

What Is Erectile Dysfunction?

Erectile dysfunction occurs when a man repeatedly experiences difficulty:

• Getting an erection
• Maintaining an erection
• Achieving adequate penile firmness for sexual intercourse
• Maintaining sufficient rigidity throughout sexual activity

Stress, tiredness, anxiety, excessive alcohol consumption, or other temporary factors can occasionally affect erections. However, men who experience erectile difficulties repeatedly should seek medical evaluation.

The brain, nerves, hormones, blood vessels, and penile tissues all contribute to a normal erection. Problems affecting any of these systems can therefore cause or contribute to ED.

Symptoms of Erectile Dysfunction

Men with erectile dysfunction may experience:

• Difficulty getting an erection
• Difficulty maintaining an erection
• Erections that lack sufficient firmness
• Reduced sexual confidence
• Reduced sexual satisfaction
• Difficulty completing satisfactory sexual intercourse
• Anxiety or stress related to sexual performance

Some men may also experience reduced sexual desire, premature ejaculation, or other sexual problems. These conditions can have different causes, so your doctor may evaluate them separately.

What Causes Erectile Dysfunction?

Several factors can contribute to erectile dysfunction. Doctors generally consider vascular, hormonal, neurological, psychological, medication-related, lifestyle-related, and other medical causes.

1. Vascular Causes

The penis requires adequate blood flow to develop and maintain an erection. Conditions that damage or narrow blood vessels can therefore contribute to ED.

Common vascular risk factors include:

• High blood pressure
• Diabetes
• High cholesterol
• Atherosclerosis
• Obesity
• Peripheral arterial disease
• Cardiovascular disease
• Smoking

In some men, ED can appear before other noticeable symptoms of cardiovascular disease. For this reason, persistent ED may prompt doctors to assess cardiovascular risk factors.

2. Diabetes

Diabetes significantly increases the risk of erectile dysfunction.

Persistently elevated blood glucose can damage blood vessels and nerves that control erections. Men with poorly controlled diabetes may therefore develop difficulty achieving or maintaining an erection.

Good blood sugar control, regular physical activity, weight management, and appropriate medical treatment can help reduce the effects of diabetes on erectile function.

3. Hormonal Causes

Hormonal abnormalities can also contribute to erectile problems.

Possible causes include:

• Low testosterone
• Thyroid disorders
• Elevated prolactin levels
• Other endocrine disorders

Low testosterone can also reduce sexual desire and cause fatigue or reduced energy. Doctors should confirm testosterone deficiency with appropriate testing before they consider testosterone therapy.

4. Neurological Causes

The nervous system plays an important role in initiating and maintaining an erection.

Conditions that affect the brain, spinal cord, or peripheral nerves can contribute to ED, including:

• Spinal cord injury
• Multiple sclerosis
• Parkinson’s disease
• Stroke
• Peripheral neuropathy
• Diabetes-related nerve damage

5. Prostate and Pelvic Surgery

Certain prostate and pelvic procedures can affect the nerves and blood vessels involved in erections.

Men may develop ED after:

• Radical prostatectomy
• Pelvic surgery
• Radiation therapy
• Certain colorectal procedures
• Certain bladder procedures

The risk depends on several factors, including erectile function before treatment, the type of procedure, nerve involvement, and the patient’s overall health.

6. Medicines

Certain medicines can contribute to erectile difficulties.

These may include some:

• Antihypertensive medicines
• Antidepressants
• Antipsychotic medicines
• Hormonal medicines
• Medicines that affect the cardiovascular or nervous systems

Never stop a prescribed medicine without discussing it with your doctor. If you notice ED after starting a medication, tell our urologists so they can assess possible alternatives.

7. Psychological Causes

Psychological and emotional factors can cause or worsen ED.

Common factors include:

• Performance anxiety
• Stress
• Depression
• Relationship difficulties
• Low self-esteem
• Previous negative sexual experiences

Physical and psychological factors can also occur together. For example, vascular ED can initially affect erections and subsequently create performance anxiety that further worsens the problem.

8. Lifestyle Factors

Certain lifestyle habits can increase the risk of ED.

These include:

• Smoking
• Excessive alcohol consumption
• Physical inactivity
• Obesity
• Poor diet
• Chronic stress
• Inadequate sleep

Improving these factors can support both erectile and cardiovascular health.

Types of Erectile Dysfunction

Doctors generally classify ED according to its underlying cause.

Organic Erectile Dysfunction

Organic ED results from a physical condition that affects the blood vessels, nerves, hormones, penile tissues, or other body systems.

Common examples include ED associated with:

• Diabetes
• Hypertension
• Cardiovascular disease
• Neurological disorders
• Hormonal abnormalities
• Pelvic surgery

Psychogenic Erectile Dysfunction

Psychogenic ED primarily results from psychological or emotional factors.

Performance anxiety, stress, depression, and relationship difficulties can interfere with the normal erectile response.

Some men with predominantly psychogenic ED continue to experience spontaneous or morning erections. However, this finding alone cannot establish the diagnosis.

Mixed Erectile Dysfunction

Many men experience both physical and psychological factors. Doctors call this mixed erectile dysfunction.

For example, vascular disease may initially make it difficult to maintain an erection. Repeated difficulty may then cause anxiety and loss of confidence, which can further affect sexual performance.

How Do Doctors Diagnose Erectile Dysfunction?

Our Urologists need to identify the underlying cause before selecting the most appropriate treatment.

The evaluation generally includes a detailed medical and sexual history, physical examination, and selected laboratory or specialized investigations.

1. Medical and Sexual History

Our doctor may ask about:

• When your symptoms started
• How frequently the problem occurs
• Your ability to achieve and maintain erections
• Morning or spontaneous erections
• Sexual desire
• Ejaculation
• Previous sexual difficulties
• Psychological and relationship factors
• Existing medical conditions
• Previous surgeries
• Current medications
• Smoking and alcohol consumption
• Physical activity and lifestyle

This information helps our doctor understand the pattern of ED and identify possible contributing factors.

2. Physical Examination

Our doctor may assess:

• Blood pressure
• Pulse
• Body weight and BMI
• Penis
• Testicles
• Secondary sexual characteristics
• Cardiovascular health
• Neurological function

The examination can help identify medical conditions that may contribute to ED.

3. Erectile Function Questionnaires

Our Doctors can use validated questionnaires to assess the severity of ED.

The International Index of Erectile Function (IIEF) remains a commonly used assessment tool. Doctors may also use the shorter Sexual Health Inventory for Men (SHIM) questionnaire.

These questionnaires can help establish baseline erectile function and track changes during treatment.

4. Blood Tests

Depending on your symptoms and medical history, your doctor may recommend:

• Fasting blood glucose
• HbA1c
• Lipid profile
• Serum Total testosterone
• Thyroid function tests when indicated
• Prolactin and other hormonal tests when clinically indicated

Our doctors do not need to order every test for every patient. They select investigations according to the individual’s symptoms and risk factors.

5. Penile Doppler Ultrasound

Penile Doppler ultrasound allow our doctors to assess blood flow within the penis.

Our doctors usually perform the test after administering a medication that produces an erection.

The test can help evaluate:

• Penile arterial blood flow
• Arterial insufficiency
• Veno-occlusive dysfunction
• Other penile vascular abnormalities

Our doctors generally reserve penile Doppler for patients who require a more detailed assessment of penile vascular function.

6. Nocturnal Penile Tumescence Testing

Nocturnal penile tumescence (NPT) testing records erections that occur during sleep.

Doctors may use NPT when they need additional information about whether psychological or physical factors contribute to ED.

However, doctors do not need NPT testing for every patient with erectile dysfunction.

7. PeriScope Cardiovascular Assessment

PeriScope assessment provides a non-invasive evaluation of cardiovascular and vascular health. The system simultaneously measures blood pressure in all four limbs and records ECG and pulse-wave information.

During the assessment, the healthcare professional places blood-pressure cuffs on both arms and both ankles and connects ECG electrodes to the patient. The system can then provide measurements such as the ankle-brachial index (ABI) and pulse wave velocity (PWV), which can help assess peripheral circulation and arterial stiffness.

Because vascular health plays an important role in erectile function, doctors may consider PeriScope assessment in selected men with ED, particularly when they have cardiovascular risk factors or require additional vascular assessment.

However, PeriScope does not diagnose erectile dysfunction by itself. Our doctors use it as an additional cardiovascular or vascular assessment when clinically appropriate.

8. Other Specialized Investigations

Our doctors may recommend additional tests when the diagnosis remains uncertain, when treatment does not produce the expected response, or when they suspect a specific underlying condition.

Depending on the individual patient, these investigations may include:

• Specialized vascular investigations
• Intracavernosal injection testing
• Additional hormonal testing
• Neurological assessment
• Other investigations based on clinical findings

Most men with ED do not require every advanced investigation.

Treatment of Erectile Dysfunction

Our doctors select ED treatment according to the underlying cause, severity of symptoms, general health, cardiovascular risk, medications, and individual preferences.

Treatment aims to improve erectile function while also addressing medical conditions and risk factors that contribute to ED.

1. Lifestyle Modification

Lifestyle changes form an important part of ED management.

Our doctor recommend that you:

• Stop smoking
• Reduce excessive alcohol consumption
• Exercise regularly
• Lose weight when appropriate
• Follow a balanced diet
• Improve sleep
• Manage stress
• Control diabetes
• Control blood pressure
• Manage cholesterol

These changes can improve overall cardiovascular health and may also improve erectile function.

2. Treating Underlying Medical Conditions

Our doctors manage medical conditions that contribute to ED whenever possible.

These may include:

• Diabetes
• Hypertension
• High cholesterol
• Obesity
• Hormonal disorders
• Cardiovascular disease
• Depression and anxiety

Treating these conditions can improve both general health and sexual function.

3. PDE5 Inhibitors

Our doctors commonly prescribe phosphodiesterase type-5 (PDE5) inhibitors as first-line medical treatment for ED.

Common medicines include:

• Sildenafil
• Tadalafil
• Vardenafil
• Avanafil

These medicines enhance the natural erectile response to sexual stimulation by improving blood-flow-related mechanisms in the penis.

Our doctor will select the appropriate medicine and dose based on your health and treatment requirements.

Important Safety Information

Never combine PDE5 inhibitors with nitrate medicines. This combination can cause a dangerous fall in blood pressure.

Men with significant cardiovascular disease or those taking heart medicines should discuss ED treatment with their doctor before using PDE5 inhibitors.

4. Psychological Counselling and Sex Therapy

Our doctors recommend counselling or sex therapy when psychological or relationship factors contribute to ED.

Therapy can help address:

• Performance anxiety
• Stress
• Depression
• Relationship difficulties
• Sexual communication
• Loss of sexual confidence

Men with mixed ED may benefit from counselling alongside medical treatment.

5. Testosterone Therapy

Our doctors may consider testosterone therapy for selected men who have confirmed testosterone deficiency together with compatible symptoms.

Our doctors do not prescribe testosterone simply because a man has ED.

Before starting treatment, our doctors confirm the diagnosis and assess whether testosterone therapy is appropriate.

6. Vacuum Erection Devices

A vacuum erection device (VED) uses negative pressure to draw blood into the penis and produce an erection.

The patient can then place a constriction ring around the base of the penis to help maintain the erection during sexual activity.

Our doctors may recommend VEDs for men who cannot use certain medications or who prefer a non-drug treatment.

7. Intracavernosal Injections

Intracavernosal therapy involves injecting medication directly into the erectile tissue.

Medicines such as alprostadil can produce an erection without relying entirely on sexual stimulation.

Our doctors teach patients the correct injection technique, dosage, and safety precautions before they use this treatment.

Possible complications include:

• Penile pain
• Fibrosis
• Prolonged erection or priapism
• Incorrect injection technique

8. Intraurethral or Topical Alprostadil

Our doctors can administer alprostadil through the urethra or use topical formulations in selected patients and clinical settings.

These treatments provide alternatives for men who cannot or do not wish to use oral medicines or penile injections.

Our doctor can determine whether these options suit your individual condition.

9. Penile Prosthesis

Our doctors may recommend a penile prosthesis when other treatments fail, cause unacceptable side effects, are contraindicated, or do not meet the patient’s expectations.

A surgeon places the prosthesis inside the penis to allow the patient to achieve an erection when desired.

The main types include:

• Inflatable penile prostheses
• Malleable or semi-rigid prostheses

Penile prosthesis surgery provides a definitive mechanical solution for appropriately selected men with persistent ED.

Emerging and Regenerative Treatments for Erectile Dysfunction

Researchers continue to investigate treatments that may improve penile blood flow, vascular function, tissue health, or the body’s natural repair mechanisms.

These approaches include:

• Low-Intensity Extracorporeal Shock Wave Therapy (LiESWT)
• Platelet-Rich Plasma (PRP)
• Stem-cell-based therapies

These treatments differ from established ED therapies. Researchers continue to evaluate their effectiveness, ideal patient selection, treatment protocols, and long-term outcomes.

Low-Intensity Extracorporeal Shock Wave Therapy (LiESWT)

Low-Intensity Extracorporeal Shock Wave Therapy (LiESWT) uses low-energy acoustic shock waves to stimulate selected areas of the penis.

Researchers have studied LiESWT primarily in men with vasculogenic erectile dysfunction, where impaired blood flow or vascular dysfunction contributes to ED.

Researchers believe that the acoustic waves may stimulate biological processes such as angiogenesis, endothelial activity, and tissue-repair pathways.

During treatment, the healthcare professional places a handheld applicator against selected areas of the penis and delivers low-energy acoustic waves. The treatment does not generally require an incision or injection into the penile tissue.

The 2026 EAU guideline reports that LiESWT can produce a mild improvement in erectile function among selected men with vasculogenic ED. However, studies have used different devices, treatment settings, and protocols.

The 2026 SMSNA position statement takes a more cautious position. After reviewing randomized controlled trials, the society concluded that the evidence has not consistently demonstrated a clinically meaningful benefit and recommends against routine use of energy-based restorative therapies outside appropriately approved clinical trials.

Therefore, our doctors do not present LiESWT as a guaranteed or permanent cure for erectile dysfunction.

Platelet-Rich Plasma (PRP) Therapy

Platelet-rich plasma (PRP) uses a concentrated preparation derived from the patient’s own blood. Platelets contain growth factors that may support processes involved in tissue repair, angiogenesis, and cellular regeneration.

For ED, researchers have studied PRP injections into the erectile tissue, particularly in men with organic or vasculogenic ED.

Researchers propose that the growth factors released by platelets may support neurovascular repair, angiogenesis, and smooth-muscle regeneration.

Some studies have reported improvements in erectile-function scores after PRP treatment. However, researchers have used different methods to prepare, activate, and administer PRP, and no standardized treatment protocol currently exists.

The 2026 EAU guideline states that current evidence remains insufficient to recommend PRP for routine clinical practice and recommends intracavernosal PRP only within a clinical-trial setting.

The 2026 SMSNA position statement also recommends against routine PRP treatment for ED outside appropriately approved clinical trials.

Therefore, our doctors explain the current evidence and limitations clearly before patients consider PRP for ED.

Stem Cell Therapy

Stem-cell therapy represents another regenerative approach that researchers continue to investigate for erectile dysfunction.

Researchers are studying whether stem or progenitor cells can support the repair or regeneration of:

• Blood vessels
• Nerves
• Smooth muscle
• Other components of erectile tissue

Early studies have produced interesting findings, but researchers have used different types of cells, treatment methods, doses, and patient populations across studies.

Current evidence does not establish stem-cell therapy as a routine treatment for ED. The 2026 SMSNA position statement recommends that researchers continue to evaluate these therapies within appropriately approved clinical trials.

Are Regenerative Treatments Suitable for Everyone With ED?

No. Our doctors do not recommend LiESWT, PRP, or stem-cell therapy to every man with ED.

Before considering an emerging or regenerative treatment, our doctors evaluate the underlying cause of your erectile dysfunction. Depending on your symptoms and risk factors, the evaluation may include:

• Cardiovascular risk assessment
• Diabetes evaluation
• Blood pressure measurement
• Cholesterol testing
• Hormonal assessment
• Medication review
• Psychological assessment
• Penile vascular evaluation

Established treatments such as lifestyle modification, PDE5 inhibitors, vacuum erection devices, intracavernosal injections, and penile prosthesis surgery have a more established role in ED management.

Patients considering emerging treatments should understand the available evidence, possible benefits, uncertainties, alternatives, and long-term outcomes.

Erectile Dysfunction and Heart Health

Erectile dysfunction and cardiovascular health share several important risk factors.

The blood vessels supplying the penis are relatively small, so vascular dysfunction can sometimes affect erectile function before a man develops noticeable cardiovascular symptoms.

Men with persistent ED may therefore benefit from assessment of:

• Blood pressure
• Blood sugar
• Cholesterol
• Smoking status
• Body weight
• Physical activity
• Family history of cardiovascular disease

Our doctors may recommend additional cardiovascular assessment when patients have multiple risk factors.

Erectile Dysfunction and Diabetes

Diabetes can significantly affect erectile function.

Persistently high blood glucose can damage:

• Blood vessels
• Peripheral nerves
• Autonomic nerves
• Endothelial function

These changes can make it difficult to achieve or maintain an erection.

Good diabetes control, lifestyle modification, and appropriate ED treatment can help men manage these problems.

Erectile Dysfunction After Prostate Cancer Treatment

Prostate cancer treatment can affect erectile function, particularly after radical prostatectomy or radiation therapy.

Several factors influence the risk and severity of ED, including:

• Erectile function before treatment
• Age
• Cancer characteristics
• Nerve-sparing status
• Type of treatment
• Cardiovascular health
• Diabetes and other medical conditions

Men undergoing prostate cancer treatment should discuss sexual-function concerns with their urologist. Doctors can consider appropriate treatment and rehabilitation strategies according to the patient’s individual situation.

Myths About Erectile Dysfunction

Myth 1: Erectile Dysfunction Is a Normal Part of Ageing

Fact: Age can influence erectile function, but persistent ED does not represent something men simply have to accept. Doctors can often identify contributing factors and provide treatment.

Myth 2: ED Means a Man Has No Sexual Desire

Fact: Erectile dysfunction and low sexual desire represent different problems. A man can have normal sexual desire while experiencing difficulty achieving or maintaining an erection.

Myth 3: ED Always Results From Psychological Problems

Fact: Physical conditions such as vascular disease, diabetes, neurological disorders, hormonal abnormalities, medications, and lifestyle factors can cause ED. Psychological factors can also contribute.

Myth 4: ED Medicines Work for Everyone

Fact: PDE5 inhibitors help many men, but not everyone responds in the same way. Doctors may need to review the diagnosis, medication use, dose, timing, and underlying health conditions when treatment does not work adequately.

Myth 5: PRP Provides a Proven Permanent Cure for ED

Fact: Researchers continue to study PRP as a regenerative treatment. Current evidence does not support routine clinical use, and current EAU guidance recommends intracavernosal PRP only within clinical trials.

Myth 6: Shockwave Therapy Permanently Cures ED

Fact: LiESWT may provide a mild improvement in erectile function for selected men with vasculogenic ED, according to the EAU. However, evidence remains mixed, and the 2026 SMSNA position statement does not support routine use of energy-based restorative therapies outside clinical trials.

Final Thoughts

Erectile dysfunction represents a common and treatable medical condition. Vascular disease, diabetes, hormonal abnormalities, neurological conditions, medications, psychological factors, and lifestyle habits can all contribute to ED.

Because ED can also share risk factors with cardiovascular and metabolic disease, men should seek appropriate medical evaluation rather than rely solely on self-medication.

Doctors can treat ED using lifestyle modification, management of underlying medical conditions, PDE5 inhibitors, counselling, vacuum erection devices, intracavernosal injections, and penile prosthesis surgery when appropriate.

Specialized assessments such as penile Doppler and PeriScope cardiovascular evaluation can provide additional information in selected patients.

Researchers continue to investigate emerging and regenerative treatments such as LiESWT, PRP, and stem-cell therapy. While these treatments may offer potential future approaches, patients should understand the current evidence and its limitations before choosing them. Current guidelines and professional statements continue to evaluate the role of these therapies.

If you experience persistent erectile difficulties, consult a qualified urologist. A proper evaluation can help identify the underlying cause and guide you toward the most appropriate treatment for your individual needs.
