Meet some astonishingly candid men—and their partners—as NOVA offers a revealing look at erectile dysfunction: its causes, its life-shattering effects, and the amazing progress science has made in treating it over the last 20 years. Follow some intensely personal true stories: A 24-year-old Bosnian émigré with a shrapnel injury who thought he could never make love to his wife again. A hard-driving lawyer whose cardiac-related sexual dysfunction drove him to thoughts of suicide. A newly married elderly couple determined to enjoy a physically intimate life. Step behind the scenes and witness the work of medical specialists who have made possible some of the most rapid treatment advances this century—from cumbersome pumping devices to penile implants, home injections, and now simple oral medications that were undreamed of a few years ago. For those who have benefited from these treatments, the result has been nothing short of life-changing. "It’s like a new experience," says a woman whose husband survived prostate cancer.
