Erectile Dysfunction: Causes, Symptoms and Treatment

What is erectile dysfunction?

Erectile dysfunction (ED) is the persistent inability to get or keep an erection firm enough for sex. In Malay it is called mati pucuk or lemah tenaga batin. One bad night is not ED. A pattern that lasts three months or more is.

It is far more common than most men assume. In the Massachusetts Male Aging Study, 52% of men aged 40 to 70 reported some degree of ED. It is a medical condition with identifiable causes, and it responds to treatment.

Erectile dysfunction symptoms

• Erections that are not firm enough for penetration
• Erections that fade before or during sex
• Fewer or weaker morning erections
• Needing much more stimulation than before
• Avoiding sex because of worry about performance

Low desire and premature ejaculation are separate conditions. They appear alongside ED, but they have different causes and different treatments.

Causes of erectile dysfunction

An erection is a blood flow event. Nerves signal the arteries in the penis to open, blood fills the erectile tissue, and the veins close to hold it there. Anything that interferes with blood vessels, nerves, hormones or the mind breaks that chain. In men over 40 the main cause is physical, and more than one factor is involved.

Physical causes

• Blood vessel disease. High blood pressure, high cholesterol and smoking narrow the arteries. This is the most common cause.
• Diabetes. High blood sugar damages both the small blood vessels and the nerves. Read more on diabetes and erectile dysfunction.
• Low testosterone. It lowers desire and weakens erections. See what low testosterone treatment can do for ED.
• Medication. Some blood pressure tablets, antidepressants and prostate drugs affect erections. Never stop a prescription on your own. Ask your doctor about alternatives.
• Surgery or injury. Prostate surgery, pelvic radiotherapy and spinal injury damage the nerves involved.
• Weight, alcohol and sleep. Excess weight, heavy drinking and poor sleep each lower testosterone and harm blood vessels. See how the KL lifestyle raises your ED risk.

Psychological causes

Stress, anxiety, depression and relationship strain cause ED on their own, particularly in younger men. A useful clue: if you still wake with firm erections, the blood supply works and the cause is psychological. One failed attempt also creates performance anxiety, which keeps the problem going after the original cause has passed. More in erectile dysfunction in your 20s and 30s.

Why ED is an early warning sign

The arteries in the penis are 1 to 2 mm wide. The arteries of the heart are 3 to 4 mm. Narrowing shows up in the smaller vessels first, which is why ED typically appears two to five years before heart symptoms do.

This is the strongest reason not to treat ED with tablets bought online. A tablet restores the erection while the underlying disease keeps progressing unnoticed. A proper assessment finds it early, when it is easiest to treat. More on what your ED could be telling you about heart health.

How erectile dysfunction is diagnosed

Diagnosis is quick and mostly a conversation. Nothing about it is painful. A typical first visit covers:

1. Medical and sexual history. When it started, how often it happens, whether morning erections are present, and what medication you take.
2. A short questionnaire. The IIEF-5 scores severity from mild to severe in five questions and gives a baseline to measure progress against.
3. Physical examination. Blood pressure, weight and waist, and a brief genital examination.
4. Blood tests. Fasting glucose or HbA1c, cholesterol, and a morning testosterone level.
5. Penile Doppler ultrasound. Only if needed, to measure blood flow directly.

You leave the first appointment knowing your score, the likely cause and your treatment options. See what happens at a first specialist visit.

Erectile dysfunction treatments: what works

Treatment follows the cause. These are the options with evidence behind them, in the order a specialist considers them. For how the choice is made, see the best treatment for erectile dysfunction.

Lifestyle changes

Exercise works. Around 40 minutes of moderate to vigorous aerobic exercise four times a week, kept up for six months, improves erectile function in men whose ED is linked to inactivity, weight, blood pressure or heart disease. Stopping smoking, losing weight, drinking less and sleeping properly add to it. Lifestyle change also makes every other treatment work better. Start with these 5 lifestyle changes that improve ED treatment results.

Shockwave therapy (ESWT)

Low-intensity shockwave therapy uses sound waves to stimulate new blood vessel growth in the penis. It is effective for mild to moderate ED caused by poor blood flow, and it treats the blood supply itself instead of producing a temporary effect. Sessions take about 20 minutes with no downtime. See what results to expect from ESWT.

Testosterone treatment

If blood tests confirm low testosterone, replacing it restores desire and improves erections. It is not a treatment for men whose levels are normal.

PRP injections (P-Shot)

Platelet-rich plasma is prepared from your own blood and injected into the erectile tissue to support repair. It is a regenerative treatment, planned together with shockwave therapy. Compare the options in shockwave therapy vs PRP vs stem cell therapy.

Counselling

When anxiety or relationship strain is part of the picture, counselling or sex therapy treats it directly. It combines well with medical treatment and works best when partners attend together. See erectile dysfunction and your relationship. For partners, see how to talk to him about ED treatment.

Where medication fits

Prescription tablets restore an erection for a few hours, and for some men they are part of the right plan. They do not treat the cause, and they have side effects such as headache, flushing and a blocked nose. They are dangerous alongside nitrate heart medicines. A specialist checks your heart health and current medication first, explains what to expect and decides whether tablets belong in your plan at all.

Devices, injections and surgery

Vacuum pumps, self-injection therapy and penile implants are established options for severe erectile dysfunction. Your specialist arranges these when they are needed.

Supplements and “natural” cures

Tongkat ali, maca, horny goat weed and similar products are heavily marketed for ED. None has evidence comparable to the treatments above. Worse, health authorities regularly find “herbal” sexual enhancement products laced with undeclared prescription drugs at unknown doses. Skip them. The money is better spent on a diagnosis.

Is there a permanent cure for erectile dysfunction?

Yes, for ED caused by medication, low testosterone, anxiety or lifestyle: it reverses once the cause is corrected. ED caused by long-standing diabetes or blood vessel disease is managed with ongoing treatment, and it is managed well: men return to a satisfying sex life with the right plan. The earlier it is assessed, the more reversible it is.

When to see a specialist

See a men’s health specialist if erection problems have lasted more than a few weeks, are getting worse, or are affecting your confidence or relationship. See one promptly if you also have diabetes, high blood pressure, chest discomfort or breathlessness on exertion.

A men’s health specialist takes the history, runs the tests and finds the cause, then builds the treatment plan around it. When you are ready for that step, see erectile dysfunction treatment in Kuala Lumpur.
