What is ED
ED is the inability of a man to obtain or maintain an erection.
The Massachusetts Male Aging Study found that 52% men aged 40-70 had ED to some extent and almost 10% could not have an erection at all.
The Cross-National Survey on Men's Health Issues found that ED rose with age, with men aged 70-75 being 14 times more likely to have ED than men 20-29.
