Vacuum erection therapy was developed in 1961 by Geddings Osbon. A .sufferer of ED, he refused to accept the fact that he could no longer have sexual intimacy with his wife of three decades. Working intently the next couple of years, he invented a plastic device, actually an external vacuum, that was capable of inducing an erection. A reversible, noninvasive form of dealing with ED, the vacuum device was used by Obson for more than twenty years. In 1983, he was awarded a patent for it. The company he founded, Osbon Medical Systems, still manufactures and distributes his Erecaid vacuum device worldwide.

The device acts in a very simple way. When a man wants to have in erection, he places a clear plastic cylinder over his penis, and either a manual or special electrical pump is used to create negative pressure in the tube. Regardless of the source of the erection problem, this PRESSURE causes vessels in the penis to fill with blood, just as they would in a normal erection. Once an erection is achieved—it may take two minutes or so—a flexible tension ring is slipped off the bottom of cylinder around the base of the penis to keep blood from flowing out of the penis, thereby allowing it to stay hard when the cylinder is removed. The resulting erection may be safely sustained for at least thirty minutes. Allowing the erection to last longer than that can produce damage to delicate erectile tissue.

The pump does have several advantages, the primary ones being that it is very safe and free of side effects. And it can be utilized whenever an erection is desired. Some urologists are now recommending pump use following prostate and penile surgery to promote erections and thereby protect the penis from potential damage caused by the lack of regularly occurring nocturnal erections.

In day-to-day use, some pump users complain that their penis feels numb, or that it becomes discolored, misshapen, and cold to the touch. Many speak of the interruption of intimacy that using it brings during lovemaking. Research shows that about 7 percent of men using it experience mild discomfort upon ejaculation or varying degrees of ejaculation impairment. The pump costs between $400 to $500 and is available only with a physician’s prescription.
