Sexual addiction: many conceptions, minimal data.

Sexual addiction has received increasing attention in the past decade. We review existing literature on (a) competing conceptualizations of this syndrome as constituting an addictive, obsessive-compulsive, or impulse control disorder; (b) symptomatology and progression; (c) etiological models; and (d) treatment approaches. Based on this review, we conclude by identifying questions requiring resolution via empirical investigation.
