Sexual dysfunction can be classified into two types: Sexual dysfunction (FSD) and sexual dysfunction of the genitals (SDF).
Sexual dysfunction refers to difficulties experienced by individuals or couples at any stage of the sexual response cycle, which inhibits satisfaction with sexual activity. Sexual dysfunction is a condition in which an individual or couple has difficulty in all stages of normal sexual activity, including sexual intercourse, oral sex, anal sex and vaginal intercourse. It can include difficulty maintaining an erection or experiencing an orgasm as well as the inability to orgasm during sexual intimacy.
Although recent pharmacological advances have generated increased public interest and increased demand for erectile dysfunction-related clinical services, epidemiological data on sexual dysfunction are relatively sparse. Sexual dysfunction is characterized by psychophysiological changes associated with the sexual response cycle in both men and women. The strong association observed in NHSLS data suggests that sexual dysfunction is the most common cause of female anorgasmia and premature ejaculation in men, although the role of hormonal changes in the development of FSD and other sexual disorders has yet to be investigated.
