Sexual dysfunction is characterized by inhibition of sexual desire or of psychophysiological changes that usually characterize sexual response. Included are female "sexual arousal disorder, " SEXUAL AROUSAL DISORDER, male "erectile disorder, " ERECTILE DISORDER, and hypoactive "sexual desire disorder" SEXUAL DESIRE DISORDER.
The concept of human "sexuality" SEXUALITY is broad and complex. All persons are sexual beings from birth to death. Acute and chronic disorders, disabling neurologic injury and disease, and aging may necessitate adaptations in the ways in which sexuality is expressed, but the individual with a sexual dysfunction, no matter how severe, does not cease to be a sexual being.
Because of the complexity of human sexuality, specific etiologies of sexual dysfunction can be classified as pathophysiological, psychological, environmental, or maturational. Altered body function related to endocrine disease, surgery, trauma, radiation, or cancer can be a primary or secondary cause of dysfunction. Lack of information, misinformation, developmental disability, absence of an effective role model, and physical and sexual abuse can alter sexual function, as can lack of privacy, fear or guilt, an incompatible or abusive partner, and excessive stress.
Defining characteristics include verbalization of the problem, whether actual or perceived, limitation imposed by disease or therapy, and reported inability to achieve desired satisfaction.
