It is possible to draw blood into the penis with a vacuum device, generated by a pump attached to an air-tight chamber that fits over your penis. This treatment, which can be used daily, is optimal for men who do not want or are not suitable for drug treatment. The blood is held there by a rubber-retaining ring around the base of the penis.

There is also a semirigid rubber sheath that can permit penetration when fitted over your penis.
When used properly, these devices are safe, but they may cause mild discomfort in some men including bruising, pain in the penis, numbness, and blocked ejaculation. These devices are best prescribed by your doctor and used as directed.
