Sexual
dysfunction may have physiological or psychological causes
or a combination of both. Between 10-52% of men at some
point in their lives will experience some type of sexual
dysfunction. One recent study in the Journal of American
Medical Association (1999) found sexual dysfunction common
in 31% of men age 18 to 59.
