What is Erectile Dysfunction?
Erectile dysfunction, or ED, is the most common sex problem that men report to their doctor. It affects as many as 30 million men. Also, you can prefer penile extension that increase your men confidence.penis enlargement surgery
ED is defined as trouble getting or keeping an erection that’s firm enough for sex.
Though it’s not rare for a man to have some problems with erections from time to time, ED that is progressive or happens routinely with sex is not normal, and it should be treated.
ED can happen:
- Most often when blood flow in the penis is limited or nerves are harmed
- With stress or emotional reasons
- As an early warning of a more serious illness, like: atherosclerosis (hardening or blocked arteries), heart disease, high blood pressure or high blood sugar from Diabetes
Finding the cause(s) of your ED will help treat the problem and help with your overall well-being. As a rule, what’s good for your heart health is good for your sex health.
How Erections Work
During sexual arousal, nerves release chemicals that increase blood flow into the penis. Blood flows into two erection chambers in the penis, made of spongy muscle tissue (the corpus cavernous). The corpus cavernous chambers are not hollow.
During erection, the spongy tissues relax and trap blood. The blood pressure in the chambers makes the penis firm, causing an erection. When a man has an orgasm, a second set of nerve signals reach the penis and cause the muscular tissues in the penis to contract and blood is released back into a man’s circulation and the erection comes down.
When you are not sexually aroused, the penis is soft and limp. Men may notice that the size of the penis varies with warmth, cold or worry; this is normal and reflects the balance of blood coming into and leaving the penis.
With Erectile Dysfunction (ED), it is hard to get or keep an erection that is firm enough for sex. When ED becomes a routine and bothersome problem, your primary care provider or a Urologist can help.
ED may be a major warning sign of cardiovascular disease indicating blockages are building in a man’s vascular system. Some studies have shown men with ED are at significant risk of getting a heart attack, stroke or circulatory problems in the legs. ED also causes:
- Low self-esteem
- Distress for the man and his partner
If ED is affecting a man’s well-being or his relationships, it should be treated. Treatment aims to fix or enhance erectile function, help circulatory health and help the quality of a man’s life.
ED can result from health problems, emotional issues, or from both. Some known risk factors are:
- Being over age 50
- Having high blood sugar (Diabetes)
- Having high blood pressure
- Having cardiovascular disease
- Having high cholesterol
- Using drugs or drinking too much alcohol
- Being obese
- Lacking exercise
Even though ED becomes more common as men age, growing old is not always going to cause ED. Some men stay sexually functional into their 80s. ED can be an early sign of a more serious health problem. Finding and treating the reason for ED is a vital first step.
Physical Causes of ED
ED happens when:
- There is not enough blood flows into the penis
Many health issues can reduce blood flow into the penis, such as hardened arteries, heart disease, high blood sugar (Diabetes) and smoking.
- The penis cannot trap blood during an erection
If blood does not stay in the penis, a man cannot keep an erection. This issue can happen at any age.
- Nerve signals from the brain or spinal cord do not reach the penis
certain diseases, injury or surgery in the pelvic area can harm nerves to the penis.
- Diabetes can cause small vessel disease or nerve damage to the penis
- Cancer treatments near the pelvis can affect the penis’ functionality
Surgery and or radiation for cancers in the lower abdomen or pelvis can cause ED. Treating prostate, colon-rectal or bladder cancer often leaves men with ED. Cancer survivors should see a Urologist for sexual health concerns.
- Drugs used to treat other health problems can negatively impact erections
Patients should talk about drug side effects with their primary care doctors.
Emotional Causes of ED
Normal sex needs the mind and body working together. Emotional or relationship problems can cause or worsen ED.
Some emotional issues that can cause ED are:
- Relationship conflicts
- Stress at home or work
- Stress from social, cultural or religious conflicts
- Worry about sex performance
The treatment for ED starts with taking care of your heart and vascular health. Your doctor may point out ‘risk factors’ that can be changed or improved.
You may be asked to change certain food habits, stop smoking, increase workouts or stop using drugs or alcohol. You may be offered alternatives to the drugs you take. (Never stop or change prescription drugs without first talking to your health care provider.)
Your health care provider may also suggest treating emotional problems. These could stem from relationship conflicts, life’s stressors, depression or anxiety from past problems with ED (performance anxiety).
The treatments below are available to treat ED directly.
Non-invasive treatments are often tried first. Most of the best-known treatments for ED work well and are safe. Still, it helps to ask your health care provider about side effects that could result from each option:
- Oral drugs or pills known as phosphodiesterase type-5 inhibitors are most often prescribed in the U.S. for ED (Viagra, Cialis, Levitra, Stendra)
- Testosterone Therapy (when low testosterone is detected in blood testing)
- Penile Injections (ICI, intracavernosal Alprostadil)
- Intraurethral medication (IU, Alprostadil)
- Vacuum Erection Devices
- Penile Implants
- Surgery to bypass penile artery damage for some younger men with a history of severe pelvic trauma. Penile vascular surgery is not recommended for older men with hardened arteries.
Oral Drugs (PDE5 inhibitors)
Drugs known as PDE type-5 inhibitors increase penile blood flow. These are the only oral agents approved in the U.S. by the Food and Drug Administration for the treatment of ED.
For best results, men with ED take these pills about an hour or two before having sex. The drugs require normal nerve function to the penis. PDE5 inhibitors improve on normal erectile responses helping blood flow into the penis. Use these drugs as directed. About 7 out of 10 men do well and have better erections. Response rates are lower for Diabetics and cancer patients.
If you are taking nitrates for your heart, you SHOULD NOT take any PDE5 inhibitors. Always speak with your health care provider before using a PDE5 inhibitor to learn how it might affect your health.
Most often, the side effects of PDE5 inhibitors are mild and often last just a short time. The most common side effects are:
- Stuffy nose
- Facial flushing
- Muscle aches
In rare cases, the drug Viagra ® can cause blue-green shading to vision that lasts for a short time. In rare cases, the drug Cialis ® can cause or increase back pain or aching muscles in the back. In most cases, the side effects are linked to PDE5 inhibitor effects on other tissues in the body, meaning they are working to increase blood flow to your penis and at the same time impacting other vascular tissues in your body. These are not ‘allergic reactions’.
In those rare cases where a low sex drive and low blood levels of Testosterone are at fault for ED, Testosterone Therapy may fix normal erections or help when combined with ED drugs (PDE type 5 inhibitors).
Vacuum Erection Device
A vacuum erection device is a plastic tube that slips over the penis, making a seal with the skin of the body. A pump at the other end of the tube makes a low-pressure vacuum around the erectile tissue, which results in an erection. An elastic ring is then slipped onto the base of the penis. This holds the blood in the penis (and keeps it hard) for up to 30 minutes. With proper training, 75 out of 100 men can get a working erection using a vacuum erection device.
Intracavernosal (ICI) and Urethra (IU) Therapies
If oral drugs don’t work, the drug Alprostadil is approved for use in men with ED. This drug comes in two forms, based on how it is to be used: intracavernosal injection (called “ICI”) or through the urethra (called “IU therapy”).
Alprostadil is injected into the side of penis with a very fine needle. It’s of great value to have the first shot in the doctor’s office before doing this on your own. Self-injection lessons should be given in your doctor’s office by an experienced professional. The success rate for getting an erection firm enough to have sex is as high as 85% with this treatment. Many men who do not respond to oral PDE5 inhibitors can be ‘rescued’ with ICI.
ICI Alprostadil may be used as a mixture with two other drugs to treat ED. This combination therapy called “bimix or trimix” is stronger than alprostadil alone and has become standard treatment for ED. Only the Alprostadil ingredient is FDA approved for ED. The amount of each drug used can be changed based on the severity of your ED, by an experienced health professional. You will be trained by your health professional on how to inject, how much to inject and how to safely raise the drug’s dosage if necessary.
ICI therapy often produces a reliable erection, which comes down after 20-30 minutes or with climax. Since the ICI erection is not regulated by your penile nerves, you should not be surprised if the erection lasts after orgasm. The most common side effect of ICI therapy is a prolonged erection. Prolonged erections (>1 hour) can be reversed by a second injection (antidote) in the office.
Men who have penile erections lasting longer than two to four hours should seek Emergency Room care. Priapism is a prolonged erection, lasting longer than four hours. It is very painful. Failure to undo priapism will lead to permanent penile damage and untreatable ED.
Intraurethral (IU) Therapy
For IU therapy, a tiny medicated pellet of the drug, Alprostadil, is placed in the urethra (the tube that carries urine out of your body). Using the drug this way means you don’t have to give yourself a shot, unfortunately it may not work as well as ICI. Like ICI therapy, IU Alprostadil should be tested in the office, before home usage.
The most common side effects of IU alprostadil are a burning feeling in the penis. If an erection lasts for over four hours, it will need medical attention to make it go down.
The main surgical treatment of ED involves insertion of a penile implant (also called penile prostheses). Because penile vascular surgery is not recommended for aging males who have failed oral PDE5 inhibitors, ICI or IU therapies, implants are the next step for these patients. Although placement of a penile implant is a surgery which carries risks, they have the highest rates of success and satisfaction among ED treatment options.
Penile implants are devices that are placed fully inside your body. They make a stiff penis that lets you have normal sex. This is an excellent choice to improve uninterupted intimacy and makes relations more spontaneous.
Several restorative or regenerative treatments are under investigation for the future treatment of ED:
- Extracorporeal shock wave therapy (ESWT) – low-intensity shock waves that aim to fix the erectile tissues and help restore natural erections.
- Intracavernosal injection of stem cells – to help cavernous tissue regrowth
- Intracavernosal injection autologous platelet rich plasma (APRP) – to help cavernous tissue regrowth
These are not currently approved by the FDA for ED management, but they may be offered through research studies (clinical trials). Patients who are interested should discuss the risks and benefits (informed consent) of each, as well as costs before starting any clinical trials. Most therapies not approved by the FDA are not covered by government or private insurance benefits.
Supplements are popular and often cheaper than prescription drugs for ED. However, supplements have not been tested to see how well they work or if they are a safe treatment for ED. Patients should know that many over-the-counter drugs have been found on drug testing to have ‘bootlegged’ PDE 5 Inhibitors as their main ingredient. The amounts of Viagra, Cialis, Levitra or Stendra that may be in these supplements is not under quality control and may differ from pill to pill. The FDA has issued consumer warnings and alerts.
