Erectile Dysfunction


For a man to keep an erection rigid during sexual intercourse, blood needs to stay in the penis until the man ejaculates. Veno-occlusion, the constriction of veins, occurs to trap the blood inside.

Once the man climaxes, the veins will dilate and blood flows back into the body.

If the veins do not constrict enough, blood will leak back into the body, losing the erection. Many men with this type of erectile dysfunction find that they can get a firm erection at first, but are unable to maintain rigidity.

Erectile dysfunction is the inability to achieve and maintain an erection firm enough to have sexual intercourse, affecting up to 43.5% of men in their sixties [1].

The main cause for erectile dysfunction is venous leak, presented in over 80% of cases in Singapore.
