Prevalence and comorbidity of sexual dysfunctions in a Portuguese clinical sample.

We investigated the prevalence and comorbidity of sexual dysfunction in a clinical Portuguese sample. A total of 96 participants (47 females and 49 males with a diagnosis of sexual dysfunction (DSM-IV; American Psychological Association, 1994) assigned by a group of trained sex therapists) answered the Female Sexual Function Index (FSFI; Rosen et al., 2000) and the International Index of Erectile Function (IIEF; Rosen et al., 1997). Results indicated erectile dysfunction (70%) and female hypoactive sexual desire disorders (40.4%) as the most prevalent complaints, with premature ejaculation (22.4%), vaginismus (25.5%), and female orgasmic disorder (21.3%) also showing relevant prevalences. Comorbidity studies indicated higher levels of overlapping among female sexual difficulties with strong associations between desire, subjective arousal, and orgasmic disorders, as well as between dyspareunia and vaginismus.
