What is erectile dysfunction?
A recurring inability to achieve or maintain an erection sufficient for satisfactory sexual activity. Not a source of shame, but a medical condition with clear causes.
Definition
Erectile dysfunction (ED) is the recurring inability to achieve or maintain an erection firm enough for intercourse. It is not about a single occasion when things do not work out, that happens to every man. It becomes a medical condition when the pattern persists and affects your quality of life.
How common is it?
The Massachusetts Male Aging Study shows that 52% of men between 40 and 70 experience some degree of erectile problems. Prevalence increases with age:
Despite this high prevalence, 75% of men do not dare to raise the subject with their GP. And 82% say they wish the doctor would bring it up first. So the conversation almost never starts, even though the problem is almost always treatable.
Four categories of causes
1. Vascular (most common)
Narrowed or stiffened blood vessels restrict blood flow to the erectile tissue. This is by far the most common cause in men over 40. Important: erectile problems often precede cardiovascular symptoms by 3 to 5 years. Your erection can be an early warning sign for your cardiovascular health.
2. Hormonal
Low testosterone levels affect libido, nitric oxide production, and overall erectile function. Testosterone declines by 1 to 2 percent per year from age 30. After 40, this can become clinically noticeable.
3. Neurological
Nerve damage from diabetes, spinal cord injury, MS, or prostate surgery can disrupt signal transmission between the brain and penis. After a radical prostatectomy, 25 to 75 percent of men experience some degree of erectile problems.
4. Psychogenic
Performance anxiety, stress, depression, and relationship issues can cause or worsen erectile problems. A tell-tale sign: morning erections are still present, but erection fails during sexual contact. Psychogenic ED is more common in younger men, but plays a role at every age.
Risk factors
- Diabetes: men with diabetes have a 3 times higher risk of erectile problems
- Cardiovascular conditions: high blood pressure, atherosclerosis, and high cholesterol damage the blood vessels
- Obesity: excess weight lowers testosterone and impairs vascular function
- Smoking: nicotine damages the endothelium and reduces blood flow
- Medication: blood pressure drugs, antidepressants, and antihistamines can cause erectile problems as a side effect
Treatment spectrum
Erectile dysfunction is a spectrum. Treatment follows that spectrum, from least invasive to most invasive:
- Lifestyle changes: weight loss, exercise, quitting smoking, stress reduction. This is always step one, regardless of what other treatment follows.
- Oral medication (PDE5 inhibitors): These drugs are effective in 60 to 70% of men. But they treat the symptom, not the cause. And as vascular decline progresses, their effectiveness diminishes.
- Regenerative therapy: shockwave therapy and PRP target the restoration of underlying vascular function. Not a pill, but a treatment programme aimed at tissue repair.
- Surgery (penile prosthesis): a last resort when other treatments prove insufficient. A definitive solution, but invasive and irreversible.
When to seek help?
You do not need to wait until it is "bad enough". Consider reaching out when:
- Erectile problems have persisted for more than 3 months
- You notice fewer morning erections than before
- Medication no longer works or is becoming less effective
- You have started avoiding intimacy
- It is affecting your relationship or self-confidence
The sooner you discuss it, the more options are available. And the greater the chance that a relatively straightforward approach will be sufficient.
