Sexual medicine or Psychosexual medicine as defined by Masters and Johnsons in their classic Textbook of Sexual Medicine, is "that branch of medicine that focuses on the evaluation and treatment of sexual disorders, which have a high prevalence rate." Examples of disorders treated with sexual medicine are erectile dysfunction, hypogonadism, and prostate cancer. Sexual medicine often uses a multidisciplinary approach involving physicians, mental health professionals, social workers, and sex therapists. Sexual medicine physicians often approach treatment with medicine and surgery, while sex therapists often focus on behavioral treatments. While literature on the prevalence of sexual dysfunction is very limited especially in women, about 31% of women report at least one sexual dysfunction regardless of age. About 43% of men report at least one sexual dysfunction, and most increase with age except for premature ejaculation. Scope Sexual medicine addresses issues of sexual dysfunction, sex education, disorders of sex development, sexually transmitted infections, puberty, and diseases of the reproductive system. The field connects to multiple medical disciplines with varying degrees of overlap including reproductive medicine, urology, psychiatry, genetics, gynaecology, andrology, endocrinology, and primary care. However, sexual medicine differs from reproductive medicine in that sexual medicine addresses disorders of the sexual organs or psyche as it relates to sexual pleasure, mental health, and well-being, while reproductive medicine addresses disorders of organs that affect reproductive potential. History The concept of sexual medicine did not arise in North America until the latter half of the 20th century, specifically around the time of the sexual revolution during the 1960s and 70s where the baby boomer generation had an increase in birth control pill use. Prior to that, open discussion of sex was seen as taboo. Psychoanalytic theories about sexuality, such as those proposed by Sigmund Freud and Helene Deutsch, were considered highly controversial. It was not until the post-World War II baby boom era and the sexual revolution of the 1960s and 1970s that sex, and subsequently sexual disorders, became a more accepted topic of discussion. In fact, urologists were the first medical specialty to practice sexual medicine. Not only does their practice focus on the urinary tract (the kidneys, urinary bladder, and urethra), there is a large emphasis on male reproductive organs and male fertility. Today, sexual medicine has reached a wider range of medical specialties, as well as psychologists and social workers, to name a few. What really opened the doors for societal normalcy
