Erectile dysfunction: causes, treatment and when to see a doctor
Erectile dysfunction is the inability to get or keep an erection firm enough for sex. It is common, it is treatable, and it is not a sign of weakness or a verdict on your manhood. It is a medical problem, and it behaves like one.
What many men do not realise is that it can be the first clue to something else going on in the body, often in the blood vessels or the nerves. That is why it is worth taking seriously rather than hiding.
This article covers the common causes, what an honest assessment involves, the treatments that work, and the warning signs that mean you should not wait.
What is happening, physically
An erection is a plumbing and signalling event. Blood vessels in the penis relax and fill; other vessels hold the blood in place; nerves carry the messages; and hormones set the background. A problem anywhere in that chain shows up as trouble getting or keeping an erection.
Because the blood vessels are so central, erectile dysfunction is often an early sign of narrowed arteries. The arteries in the penis are smaller than the ones around the heart, so they can show the effects of a circulation problem before the heart does. In this way, a man's erection can warn him about his heart.
Common causes
The physical causes are the commonest. Narrowed arteries and the conditions that drive them: high blood pressure, high cholesterol, diabetes, smoking, and a sedentary life. Diabetes damages both blood vessels and nerves. Hormone problems, including low testosterone, play a part in some men. So do nerve injuries from surgery or pelvic trauma.
Some medicines contribute, including certain blood pressure tablets and some antidepressants. Do not stop any prescribed medicine on your own. If you suspect a medicine is the cause, raise it with your doctor, who can often adjust the plan.
Then there are the psychological causes, which are real and not imaginary. Stress, anxiety about performance, depression, exhaustion, and relationship strain can all interfere. Often physical and emotional factors work together. A man who has one bad night starts to worry, the worry makes the next night worse, and a pattern forms.
Alcohol and smoking both worsen the problem, and so does a poor diet and obesity. These are worth naming because they are also the places where change helps most.
What an honest assessment looks like
A doctor will ask about your erections, but also about your general health: blood pressure, sugar, cholesterol, mood, sleep, and any medicines you take. Do not leave out herbal or traditional remedies, even if you feel shy about them. Some contain ingredients that interact badly with other drugs.
A physical examination checks circulation and nerves. Blood tests usually look at blood sugar and cholesterol, and often at hormone levels. This is not a snooping exercise. It is the fastest route to finding a treatable cause.
Treatments that work
Treatment depends on the cause and comes in stages. The first line for most men is a category of tablets known as PDE5 inhibitors, prescribed after assessment. They help blood flow and work well for many men, but they are not suitable for everyone and must be prescribed and monitored by a clinician.
One safety point is worth repeating because it can be dangerous. If you take heart medicines that contain nitrates, these tablets can cause a dangerous drop in blood pressure and must not be used together. Always tell the prescriber every medicine and supplement you take.
Other options include treatments delivered by injection or into the penis, a vacuum device, and surgery in the form of a penile implant for men who do not respond to other approaches. Hormone treatment helps when a hormone deficiency is the cause. Whatever the route, the point is that most men can be helped.
Alongside medical treatment, the everyday changes matter. Regular exercise, weight loss if you carry extra weight, stopping smoking, cutting back on alcohol, and treating blood pressure, sugar and cholesterol all improve erectile function and the health of the arteries behind it. Good sleep and attention to stress help too. These are not vague advice. They act on the same blood vessels the tablets act on.
What does not help
Unknown mixtures sold as "man power" preparations, unregulated herbs, and injections offered outside a clinic may contain hidden drugs, including some that raise blood pressure or interact with heart medicines. They can also mask a condition that needs proper assessment. Save your money and your safety.
Questions men ask quietly
Does it mean I will have a heart attack? Not necessarily, and it does not mean it is certain. What it does mean is that your blood vessels deserve a check, especially if you also have diabetes, high blood pressure or high cholesterol. Treating those protects your heart as well as your erections.
Will I be on tablets forever? It depends on the cause. If the cause is reversible, the need may pass. If it is long term, treatment may continue. Either way, the point is a working sex life, not a count of tablets.
Do I have to tell my partner? That is your choice. Many men find that a partner who understands the medical reason feels less personally rejected, which eases the pressure at home. If you would rather not, you can still be assessed and treated on your own.
When to see a doctor
See a doctor if erections are consistently a problem, if you need help most or all of the time, or if the trouble came on suddenly. Come sooner if you also have diabetes, high blood pressure, high cholesterol, or a family history of early heart disease, because your erectile function may be telling you something about your heart.
Get emergency help right away for chest pain that spreads to the arm or jaw, chest pain with sweating or breathlessness, or sudden difficulty breathing. Do not assume it is unrelated simply because it happened during or after sex.
Seek urgent care for an erection that lasts several hours and will not go down, which is a painful emergency that can damage the penis; for sudden severe pain in the penis; or for weakness on one side of the body or difficulty speaking.
If you take a nitrate heart medicine and have been considering erectile dysfunction tablets, do not combine them. Speak to a doctor first.
Next steps
Book an appointment and say plainly what is happening. Bring a list of every medicine and supplement you take, and be ready to talk about your general health. Ask about the tests you need and what treatment would suit you. There is no need to manage this alone, and in many men the first visit leads to a diagnosis that improves far more than their sex life.
