6.85 55 minutes NOVA reports on new hope for victims of erectile dysfunction, also known as impotence. Among the promising therapies covered in the program are ones developed by Dr. Irwin Goldstein of Boston University School of Medicine and Dr. Harin Padma-Nathan, director of the Male Clinic in Santa Monica, CA. Actual cases are profiled, featuring men talking candidly about their problem—and going through treatment—on camera. Erectile dysfunction affects an estimated 52% of men between the ages of 40 and 70.
