A doctor can prescribe a penis pump as part of erectile dysfunction treatment. These pumps are FDA (Food and Drug Administration) approved and available from pharmacies. However, there are many excellent penis pumps available over the counter from specialist health stores and sex outlets. You don't need a prescription to use a penis pump; neither do you need to suffer from any specific medical complaint to enjoy their benefits. Treating ED is only one use for penis pumps; there are all kinds of fringe benefits and ways to enjoy the feelings and results they bring.
