Sexual dysfunction related to psychiatric disorders: a systematic review

Sexual dysfunction is thought to be highly prevalent in patients with psychiatric disorders. Factors such as the use of psychotropic substances (ie, psychopharmaceuticals and drugs), age, or somatic diseases may contribute to sexual problems, but the extent to which psychopathology itself affects sexual functioning is not well understood.

The study sought to provide an overview of the literature on the prevalence of sexual dysfunction in psychotropic-free and somatic disease-free psychiatric patients.

A systematic review (PRISMA [Preferred Reporting Items for Systematic Reviews and Meta-Analyses]) was conducted by 2 authors (TH and AWMP) independently, with the review process being monitored by a third author. Relevant articles on the relationship between sexual dysfunctions and psychopathology were searched in PubMed, Web of Science, and PsycINFO from inception until June 16, 2022. The study methods were entered in the international register of systematic reviews PROSPERO (2021, CRD42021223410).

The main outcome measures were sexual dysfunction and sexual satisfaction.

Twenty-four studies were identified, including a total of 1199 patients. These studies focused on depressive disorders (n = 9 studies), anxiety disorders (n = 7), obsessive- compulsive disorder (OCD) (n = 5), schizophrenia (n = 4), and posttraumatic stress disorder (n = 2). No studies on bipolar disorder were found. Reported prevalence rates of sexual dysfunction in psychiatric disorders were 45% to 93% for depressive disorders, 33% to 75% for anxiety disorders, 25% to 81% for OCD, and 25% for schizophrenia. The most affected phase of the sexual response cycle was sexual desire, in both men and women with depressive disorders, posttraumatic stress disorder, and schizophrenia. Patients with OCD and anxiety disorders most frequently reported dysfunction in the orgasm phase, 24% to 44% and 7% to 48%, respectively.

The high prevalence of sexual dysfunction requires more clinical attention by means of psychoeducation, clinical guidance, sexual anamnesis, and additional sexological treatment.

This is the first systematic review on sexual dysfunction in psychotropic-free and somatic disease-free psychiatric patients. Limitations include the small number of studies, small sample sizes, the use of multiple questionnaires (some not validated), which may contribute to bias.

A limited number of studies identified a high prevalence of sexual dysfunction in patients with a psychiatric disorder, with substantial variation between patient groups in frequency and phase of reported sexual dysfunction.
