FSFI

Meaning

The FSFI, or Female Sexual Function Index, is a widely used, multi-dimensional, self-report questionnaire designed to assess the quality and quantity of sexual function in women over the preceding four weeks. This comprehensive instrument measures six distinct domains of sexual response: desire, arousal, lubrication, orgasm, satisfaction, and pain. It serves as a foundational clinical and research tool for quantifying sexual function and identifying potential dysfunction across a spectrum of patient populations.
