According to Dr. Joel Kaplan, a diplomat at the American Board of Sexology in Washington, D.C., "When the first airtight vacuum pump cylinder is placed around your penis, blood rushes into the muscle portion of your penis. The muscle tissue expands to the maximum, breaks down, and then rebuilds into larger and stronger muscles, similar to body-building." Dr Kaplan has been a pioneer in the use of vacuum pump therapy for penis enlargement and sexual dysfunction.
