The epidemiology and definition of female sexual disorders.

Female sexual dysfunction (FSD) is a multifactorial condition that has anatomical, physiological, medical, psychological, and social components. Similar to erectile dysfunction in men, FSD is highly prevalent and often undertreated. Due to the development of successful treatment for male erectile dysfunction, FSD is receiving increased attention. Only a few studies dealing with epidemiology of female sexual dysfunction are available in the literature. However, research efforts in the field are increasing. This overview presents currently used classification systems, recently updated definitions, as well as prevalence data on the different entities of female sexual disorders.
