Now more than five decades old, the field of sex therapy remains active, continuously incorporating in its practice advances in psychology and medicine. In this article, we present a brief historical perspective of the sex therapy practice as well as its present state. We discuss the how the current biopsychosocial paradigm advocates sexual dysfunction as an interaction of predisposing, precipitating, and maintaining factors and calls for the cooperation of professionals from different areas to effectively evaluate and treat patients. We conclude that the concerns of modern sex therapy have moved past rescuing sexual function and toward minimizing distress while enhancing sexual satisfaction.
