What is Erectile Dysfunction?

Erectile dysfunction, or ED (It used to be called impotence), is the inability to achieve or sustain an erection suitable for sexual intercourse. A penile erection is the hydraulic effect of blood entering and being retained in sponge-like bodies within the penis. The process is most often initiated as a result of sexual arousal, when signals are transmitted from the brain to nerves in the penis. Problems with erections may stem from medications, chronic illnesses, poor blood flow to the penis, drinking too much alcohol, or being too tired. Erectile dysfunction can occur at any age, but it is more common in men older than 75.

Difference Between Erectile Dysfunction and Impotence:

The word "impotence" may also be used to describe other problems that interfere with sexual intercourse and reproduction, such as lack of sexual desire and problems with ejaculation or orgasm. Using the term erectile dysfunction clarifies that those other concerns are not involved.

An occasional issue achieving an erection is nothing to worry about. But failure to do so more than 50% of the time at any age may indicate a condition that needs treatment.

About 40% of men in their 40s report at least occasional difficulties getting and maintaining erections. So do more than half (52%) of men aged 40 to 70, and about 70% of men in their 70s.

Common Causes of Erectile Dysfunction

Erectile dysfunction can be caused by several things, including:

Your feelings can also lead to erectile dysfunction.

For example, feeling nervous about having sex after a bad experience or because of a previous episode of impotence and feeling self-conscious that you can't enjoy sex, or thinking that your partner is reacting negatively to you.

Erectile dysfunction happens to about one in ten men.

Today there are several treatments that can help, so there is no longer any need for males to suffer as often simple lifestyle changes, medications, and other treatments can be used to treat ED. Quitting smoking, losing excess weight, and increasing physical activity may help some men regain sexual function.
