Vacuum erection devices for erectile dysfunction: Can they cause blood in semen?

Although unsettling, blood in semen (hemospermia) usually isn't a sign of a serious problem. In your particular circumstance, the blood may be due to back pressure on your prostate from the vacuum erection device. However, you should share this information with your doctor and review the instructions for the vacuum erection device to make sure you're using it properly.

Most men with erectile dysfunction can achieve erections using a vacuum erection device. These devices, which consist of a hollow chamber attached to a suction source, fit over the penis and create a seal. Suction applied to the chamber draws blood into the penis, producing an erection. Once an erection is achieved, a constriction ring or band is placed at the base of the penis to prevent blood from flowing out of the penis.

When used as directed, vacuum erection devices are generally safe and effective. However, side effects may include:

• Bruising of the penis
• Penis pain
• Impaired ejaculation
