What is Erectile Dysfunction and Why I Get ED ?

Erectile dysfunction (impotence) is the inability to get and keep an erection firm enough for sex.

Having erection trouble from time to time isn’t necessarily a cause for concern. If erectile dysfunction is an ongoing issue, however, it can cause stress, affect your self-confidence and contribute to relationship problems. Problems getting or keeping an erection can also be a sign of an underlying health condition that needs treatment and a risk factor for heart disease.

If you’re concerned about erectile dysfunction, talk to your doctor — even if you’re embarrassed. Sometimes, treating an underlying condition is enough to reverse erectile dysfunction. In other cases, medications or other direct treatments might be needed.

Symptoms

Erectile dysfunction symptoms might include persistent:

  • Trouble getting an erection
  • Trouble keeping an erection
  • Reduced sexual desire

 

Why I get Erectile Dysfunction ?

Depression – The brain is an often-overlooked erogenous zone. Sexual excitement starts in your head and works its way down. Depression can dampen your desire and can lead to erectile dysfunction. Ironically, many of the drugs used to treat depression can also suppress your sex drive and make it harder to get an erection, and they can cause a delay in your orgasm.

Alcohol – You might consider having a few drinks to get in the mood, but overindulging could make it harder for you to finish the act. Heavy alcohol use can interfere with erections, but the effects are usually temporary. The good news is that moderate drinking — one or two drinks a day — might have health benefits like reducing heart disease risks. And those risks are similar to erectile dysfunction risks.

Medications – The contents of your medicine cabinet could affect your performance in the bedroom. A long list of common drugs can cause ED, including certain blood pressure drugs, pain medications, and antidepressants. But do not stop taking any medicines without talking to your doctor first. Street drugs like amphetamines, cocaine, and marijuana can cause sexual problems in men, too.

Stress – It’s not easy to get in the mood when you’re overwhelmed by responsibilities at work and home. Stress can take its toll on many different parts of your body, including your penis. Deal with stress by making lifestyle changes that promote well-being and relaxation, such as exercising regularly, getting enough sleep, and seeking professional help when appropriate.

Anger – Anger can make the blood rush to your face, but not to the one place you need it when you want to have sex. It’s not easy to feel romantic when you’re raging, whether your anger is directed at your partner or not. Unexpressed anger or improperly expressed anger can contribute to performance problems in the bedroom.

Anxiety – Worrying that you won’t be able to perform in bed can make it harder for you to do just that. Anxiety from other parts of your life can also spill over into the bedroom. All that worry can make you fear and avoid intimacy, which can spiral into a vicious cycle that puts a big strain on your sex life — and relationship.

Middle-Aged Spread – Carrying extra pounds can impact your sexual performance, and not just by lowering your self-esteem. Obese men have lower levels of the male hormone testosterone, which is important for sexual desire and producing an erection. Being overweight is also linked to high blood pressure and hardening of the arteries, which can reduce blood flow to the penis.

Self-Image – When you don’t like what you see in the mirror, it’s easy to assume your partner isn’t going to like the view, either. A negative self-image can make you worry not only about how you look, but also how well you’re going to perform in bed. That performance anxiety can make you too anxious to even attempt sex.

Low Libido – Low libido isn’t the same as erectile dysfunction, but a lot of the same factors that stifle an erection can also dampen your interest in sex. Low self-esteem, stress, anxiety, and certain medications can all reduce your sex drive. When all those worries are tied up with making love, your interest in sex can take a nosedive.

Your Health – Many different health conditions can affect the nerves, muscles, or blood flow that is needed to have an erection. Diabetes, high blood pressure, hardening of the arteries, spinal cord injuries, and multiple sclerosis can contribute to ED. Surgery to treat prostate or bladder problems can also affect the nerves and blood vessels that control an erection.

 

Causes of Erectile Dysfunction

Male sexual arousal is a complex process that involves the brain, hormones, emotions, nerves, muscles and blood vessels. Erectile dysfunction can result from a problem with any of these. Likewise, stress and mental health concerns can cause or worsen erectile dysfunction.

Sometimes a combination of physical and psychological issues causes erectile dysfunction. For instance, a minor physical condition that slows your sexual response might cause anxiety about maintaining an erection. The resulting anxiety can lead to or worsen erectile dysfunction.

ED is not the same as premature ejaculation.

The major causes of ED include:

  • Vascular (blood vessel) disease — Erections happen when blood collects in the shaft of the penis. Vascular disease can limit the amount of blood flowing to or staying in the penis. Both can result in problems with erections.
  • Vascular disease is the most common medical cause of impotence.
  • Nerve damage — Nerves must be working normally for a man to get and keep an erection. Nerves can be damaged by diabetes, multiple sclerosis, prostate surgery or damage to the spinal cord.
  • Psychological factors — Psychological issues such as depression, anxiety, guilt or fear can sometimes cause sexual problems. At one time, these factors were thought to be the major cause of impotence. Doctors now know that physical factors cause impotence in most men with the problem. However, embarrassment or “performance anxiety” can make a physical problem worse.
  • Medications — Many medications cause problems with sexual function. These include drugs for high blood pressure, depression, heart disease and prostate cancer.
  • Hormonal problems — Abnormal levels of certain hormones can interfere with erections and sex drive. Hormonal problems, such as a low testosterone level, are an uncommon cause of impotence.

 

Physical causes of Erectile Dysfunction

In many cases, erectile dysfunction is caused by something physical. Common causes include:

  • Heart disease
  • Clogged blood vessels (atherosclerosis)
  • High cholesterol
  • High blood pressure
  • Diabetes
  • Obesity
  • Metabolic syndrome — a condition involving increased blood pressure, high insulin levels, body fat around the waist and high cholesterol
  • Parkinson’s disease
  • Multiple sclerosis
  • Certain prescription medications
  • Tobacco use
  • Peyronie’s disease — development of scar tissue inside the penis
  • Alcoholism and other forms of substance abuse
  • Sleep disorders
  • Treatments for prostate cancer or enlarged prostate
  • Surgeries or injuries that affect the pelvic area or spinal cord
  • Low testosterone

Psychological causes of erectile dysfunction

The brain plays a key role in triggering the series of physical events that cause an erection, starting with feelings of sexual excitement. A number of things can interfere with sexual feelings and cause or worsen erectile dysfunction. These include:

  • Depression, anxiety or other mental health conditions
  • Stress
  • Relationship problems due to stress, poor communication or other concerns

Risk factors

As you get older, erections might take longer to develop and might not be as firm. You might need more direct touch to your penis to get and keep an erection.

Various risk factors can contribute to erectile dysfunction, including:

  • Medical conditions, particularly diabetes or heart conditions
  • Tobacco use, which restricts blood flow to veins and arteries, can — over time — cause chronic health conditions that lead to erectile dysfunction
  • Being overweight, especially if you’re obese
  • Certain medical treatments, such as prostate surgery or radiation treatment for cancer
  • Injuries, particularly if they damage the nerves or arteries that control erections
  • Medications, including antidepressants, antihistamines and medications to treat high blood pressure, pain or prostate conditions
  • Psychological conditions, such as stress, anxiety or depression
  • Drug and alcohol use, especially if you’re a long-term drug user or heavy drinker

Complications

Complications resulting from erectile dysfunction can include:

  • An unsatisfactory sex life
  • Stress or anxiety
  • Embarrassment or low self-esteem
  • Relationship problems
  • The inability to get your partner pregnant

Prevention

The best way to prevent erectile dysfunction is to make healthy lifestyle choices and to manage any existing health conditions. For example:

  • Work with your doctor to manage diabetes, heart disease or other chronic health conditions.
  • See your doctor for regular checkups and medical screening tests.
  • Stop smoking, limit or avoid alcohol, and don’t use illegal drugs.
  • Exercise regularly.
  • Take steps to reduce stress.
  • Get help for anxiety, depression or other mental health concerns.

Diagnosis

For many people, a physical exam and answering questions (medical history) are all that’s needed for a doctor to diagnose erectile dysfunction and recommend a treatment. If you have chronic health conditions or your doctor suspects that an underlying condition might be involved, you might need further tests or a consultation with a specialist.

Tests for underlying conditions might include:

  • Physical exam. This might include careful examination of your penis and testicles and checking your nerves for sensation.
  • Blood tests. A sample of your blood might be sent to a lab to check for signs of heart disease, diabetes, low testosterone levels and other health conditions.
  • Urine tests (urinalysis). Like blood tests, urine tests are used to look for signs of diabetes and other underlying health conditions.
  • Ultrasound. This test is usually performed by a specialist in an office. It involves using a wandlike device (transducer) held over the blood vessels that supply the penis. It creates a video image to let your doctor see if you have blood flow problems.This test is sometimes done in combination with an injection of medications into the penis to stimulate blood flow and produce an erection.
  • Psychological exam. Your doctor might ask questions to screen for depression and other possible psychological causes of erectile dysfunction.

Treatment

The first thing your doctor will do is to make sure you’re getting the right treatment for any health conditions that could be causing or worsening your erectile dysfunction.

Depending on the cause and severity of your erectile dysfunction and any underlying health conditions, you might have various treatment options. Your doctor can explain the risks and benefits of each treatment and will consider your preferences. Your partner’s preferences also might play a role in your treatment choices.

Oral medications

Oral medications are a successful erectile dysfunction treatment for many men. They include:

  • Sildenafil (Viagra)
  • Tadalafil (Adcirca, Cialis)
  • Vardenafil (Levitra, Staxyn)
  • Avanafil (Stendra)

All four medications enhance the effects of nitric oxide — a natural chemical your body produces that relaxes muscles in the penis. This increases blood flow and allows you to get an erection in response to sexual stimulation.

Taking one of these tablets will not automatically produce an erection. Sexual stimulation is needed first to cause the release of nitric oxide from your penile nerves. These medications amplify that signal, allowing normal penile function in some people. Oral erectile dysfunction medications are not aphrodisiacs, will not cause excitement and are not needed in people who get normal erections.

The medications vary in dosage, how long they work and side effects. Possible side effects include flushing, nasal congestion, headache, visual changes, backache and stomach upset.

Your doctor will consider your particular situation to determine which medication might work best. These medications might not treat your erectile dysfunction immediately. You might need to work with your doctor to find the right medication and dosage for you.

Before taking any medication for erectile dysfunction, including over-the-counter supplements and herbal remedies, get your doctor’s OK. Medications for erectile dysfunction do not work in everyone and might be less effective in certain conditions, such as after prostate surgery or if you have diabetes. Some medications might also be dangerous if you:

  • Take nitrate drugs — commonly prescribed for chest pain (angina) — such as nitroglycerin (Nitro-Dur, Nitrostat, others), isosorbide mononitrate (Monoket) and isosorbide dinitrate (Dilatrate-SR, Isordil, Bidil)
  • Have heart disease or heart failure
  • Have very low blood pressure (hypotension)

Other medications

Other medications for erectile dysfunction include:

  • Alprostadil self-injection. With this method, you use a fine needle to inject alprostadil (Caverject, Edex) into the base or side of your penis. In some cases, medications generally used for other conditions are used for penile injections on their own or in combination. Examples include alprostadil and phentolamine. Often these combination medications are known as bimix (if two medications are included) or trimix (if three are included).Each injection is dosed to create an erection lasting no longer than an hour. Because the needle used is very fine, pain from the injection site is usually minor.Side effects can include mild bleeding from the injection, prolonged erection (priapism) and, rarely, formation of fibrous tissue at the injection site.
  • Alprostadil urethral suppository. Alprostadil (Muse) intraurethral therapy involves placing a tiny alprostadil suppository inside your penis in the penile urethra. You use a special applicator to insert the suppository into your penile urethra.The erection usually starts within 10 minutes and, when effective, lasts between 30 and 60 minutes. Side effects can include a burning feeling in the penis, minor bleeding in the urethra and formation of fibrous tissue inside your penis.
  • Testosterone replacement. Some people have erectile dysfunction that might be complicated by low levels of the hormone testosterone. In this case, testosterone replacement therapy might be recommended as the first step or given in combination with other therapies.

Penis pumps, surgery and implants

If medications aren’t effective or appropriate in your case, your doctor might recommend a different treatment. Other treatments include:

  • Penis pumps. A penis pump (vacuum erection device) is a hollow tube with a hand-powered or battery-powered pump. The tube is placed over your penis, and then the pump is used to suck out the air inside the tube. This creates a vacuum that pulls blood into your penis.Once you get an erection, you slip a tension ring around the base of your penis to hold in the blood and keep it firm. You then remove the vacuum device.The erection typically lasts long enough for a couple to have sex. You remove the tension ring after intercourse. Bruising of the penis is a possible side effect, and ejaculation will be restricted by the band. Your penis might feel cold to the touch.If a penis pump is a good treatment choice for you, your doctor might recommend or prescribe a specific model. That way, you can be sure it suits your needs and that it’s made by a reputable manufacturer.
  • Penile implants. This treatment involves surgically placing devices into both sides of the penis. These implants consist of either inflatable or malleable (bendable) rods. Inflatable devices allow you to control when and how long you have an erection. The malleable rods keep your penis firm but bendable.Penile implants are usually not recommended until other methods have been tried first. Implants have a high degree of satisfaction among those who have tried and failed more-conservative therapies. As with any surgery, there’s a risk of complications, such as infection. Penile implant surgery is not recommended if you currently have a urinary tract infection.
