The FSFI is a multidimensional questionnaire organized into 19 multiple-choice questions and divided in 6 domains which explore sexual desire, arousal, vaginal lubrication, satisfaction and sexual pain. It contains questions about sexual life in the previous 4 weeks. Each answer is given a score between 0 and 5. The final total score gives the result of the test, when it's lower than 26.5 (Wiegel et al, 2005) it suggests a possible sexual dysfunction. FSFI is easily understandable and the time required to complete it is less than 5 minutes.
