Dr. Joel Kaplan is a graduate from the University of Chicago and Saybrook Institute in San Francisco, where he received his Ph.D. in clinical psychology and human sexuality. Dr. Kaplan has also been awarded Diplomat status with the American Board of Sexology in Washington DC and is a registered sex researcher and certified sex therapist. He is currently in private practice and has been a pioneer in the usage of vacuum pump therapy for penis enlargement and sexual dysfunction.

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.
