Erectile dysfunction is when a man has difficulty getting an erection. Or keeping it long enough for sex. It’s also known as ED or impotence. It happens when not enough blood flows to the penis, preventing an erection.
It affects about 30 million men in the U.S. Some guys with ED find it difficult to either get or keep an erection every time they try to have sex. For others, ED symptoms can happen just once in a while. Either way, you should know that you’re not alone.
ABOUT
ED is not all in your head. It’s not just a part of aging that you have to accept. It’s a real medical condition, so it should be addressed like one. If you think you have ED symptoms, talk to a doctor.
*Data taken from the Massachusetts Male Aging Study. Of 1,290 respondents, 52% stated that they had some degree of ED.
What can cause ED?
ED is often caused by something physical, such as a disease, injury, or side effects from other drugs.
Medical Conditions
Although most cases of ED have a physical cause, thoughts that lead to depression, worry, or anxiety can also cause ED.
Even when ED has a physical cause, it can be made worse if it leads to depression and worry.
Diabetes is a condition where there is too much sugar, or glucose, in the blood. Over time, high blood sugar levels can damage nerves and blood vessels—like the ones that produce erections. When this occurs, diabetes can lead to ED.
In a study, up to 83% of men with diabetes had some form of ED.
Heart disease can clog or narrow the arteries. This can stop blood from flowing to the penis, and may cause ED. Talk to your doctor to make sure your heart is healthy enough for sex.
High blood pressure makes the heart work harder. This puts strain on the blood vessels, which then harden and narrow. This can prevent blood from getting to the penis and lead to ED. In a study, more than 65% of men with high blood pressure also had ED.
Additionally, some medications used to treat high blood pressure can lead to ED. Make sure your doctor is aware of all medications you are taking.
High cholesterol can clog your arteries. This can slow blood flow to the penis. The result? It can affect the quality of your erections.
In a study, high cholesterol raised men's risk of erectile dysfunction by 80%.
Obesity can cause real harm to your health. For example, it's associated with medical conditions that can affect blood flow. And when blood flow is affected, it can cause ED.
The prostate is a small gland near your bladder. It's next to the nerves that are necessary for an erection to happen. For men with prostate cancer, surgical removal of the prostate can lead to ED.
An injury to the spine can affect many functions in the body. Erectile function is no exception.
Due to nerve damage, some men with spinal cord injuries can't get erections. Others can—but can't keep them hard enough or long enough for sex.
Can your lifestyle have something to do with it?
Yes. Some lifestyle and psychological factors can play a role in causing ED, such as smoking, drinking, and stress because they may lead to conditions that affect blood circulation.
There are things you can do each day to improve your circulation and avoid some of the conditions that can lead to ED:
- Find ways to stay more active (mowing the lawn, walking the dog)
- Help manage your weight by eating healthy and watching your portion size
- Drink less alcohol
- Quit smoking. The results can be significant
- Look for ways to reduce stress in your daily life
VIAGRA helps guys with ED get and keep an erection.
And it’s been shown to effectively treat ED in guys who have certain other medical conditions. So be sure to tell your doctor about your medical conditions and medications so he can choose the right dose for you.
VIAGRA works for men with erectile dysfunction (ED) by increasing blood flow to the penis so you can get and keep an erection hard enough for sex. Individual results may vary. It’s been proven to help guys with all degrees of ED. VIAGRA usually starts to work within 30-60 minutes. And you only take it when you need it.
VIAGRA works only when you are sexually stimulated. You may take it up to 4 hours before sexual activity. So don’t worry. There's no need to rush.
After sex? Your erection should go away. In the rare event of an erection lasting more than 4 hours, seek immediate medical help to avoid long-term injury.
APPROXIMATELY
†Seventy-two percent, 80%, and 85% of the patients on 25 mg, 50 mg, and 100 mg of VIAGRA, respectively, achieved erections hard enough for sex, compared to 50% on placebo. Also, men taking VIAGRA showed an improvement in their ability to get and keep an erection versus those who took placebo.
Only your doctor can decide if VIAGRA is right for you. VIAGRA isn't right for everyone.
If you have trouble getting or keeping an erection hard enough for sex, VIAGRA may help.
