Erectile dysfunction is the inability to achieve and keep enough stiffness of the penis to enter the vagina and have sexual intercourse. Another term for this problem is impotence. It is normal for most men to have trouble having an erection sometimes when they are tired or nervous. When erectile dysfunction becomes a pattern or a long-lasting problem, however, it can deeply affect the emotional lives of men and their sex partners.
Erectile dysfunction affects older men more than younger men.
Midlife and the later years bring changes in circulation that may affect the sex organs. Couples need to be more open and understanding with each other about sexual problems such as erectile dysfunction. Fortunately, erectile dysfunction can often be cured. An erection is caused when there is increased blood flow into the penis. Penile veins then clamp down to trap blood there, causing stiffness.
