Female Sexual Function Index (FSFI)
Also known as: FSFI
The FSFI is a 19-item multidimensional self-report instrument designed to assess sexual function in women across the lifespan. Developed by Rosen and colleagues in 2000, it measures six core domains of sexual response and has become a gold standard in both clinical and research settings for evaluating female sexual dysfunction.

When to use it
The FSFI is appropriate for women aged 18 and older, including pre-, peri-, and postmenopausal women. It is particularly useful in urology and gynecology clinics for routine screening, in sex therapy settings for treatment planning, in research evaluating therapeutic interventions (e.g., hormone therapy, PDE5 inhibitors), and in epidemiologic studies of sexual health prevalence. It is not suitable for non-heterosexual partnerships without adaptation.
Strengths & limitations
- Multidimensional: captures six distinct domains of sexual response, avoiding oversimplification.
- Psychometrically robust: extensive validation across diverse populations with good internal consistency (Cronbach's α > 0.82 for most subscales) and test–retest reliability.
- Responsive to change: sensitive to treatment effects in both pharmacologic and psychotherapeutic interventions.
- Clinically actionable: subscale profiles help clinicians target interventions to specific dysfunctions rather than treating sexual dysfunction as monolithic.
- Widely adopted: facilitates comparison across studies and clinical settings worldwide.
- Heteronormative design: assumes partnered, penis-in-vagina sexual activity; interpretation unclear for same-sex partnerships or non-penetrative preferences.
- Four-week recall bias: respondents may not accurately remember frequency/severity of symptoms over extended period.
- Doesn't capture contextual factors: sexual distress, relationship satisfaction, and partner function are not measured; high FSFI scores do not guarantee satisfaction.
- Multifactorial dysfunction: when multiple domains are affected, subscale scores can mask which primary problem to address first.
Frequently asked
What score cutoff indicates sexual dysfunction?
A total FSFI score of 26.55 or lower suggests clinically significant sexual dysfunction. However, clinical judgment should incorporate patient symptom severity, distress, and relationship context; a score alone does not constitute diagnosis.
Can the FSFI be used in postmenopausal women?
Yes. The FSFI is valid across menopausal stages. However, normative interpretation may differ: postmenopausal women typically show longer arousal time and reduced lubrication due to hypoestrogenism, which is physiologically expected rather than pathologic unless accompanied by distress.
What if a woman is not sexually active?
The FSFI instructions typically ask respondents to rate function 'over the past four weeks' or 'if sexually active.' Guidelines vary on whether to administer it to abstinent women. Some clinicians administer modified versions to assess capacity for function; others defer scoring pending renewed sexual activity. Consult the clinical context.
Does a high FSFI score mean a woman is satisfied?
No. FSFI measures physiologic/behavioral function, not emotional satisfaction or relationship quality. Some women with high FSFI scores report low sexual satisfaction due to relationship conflict or low desire; conversely, some with lower function scores feel satisfied within their relationship. Administer complementary measures of sexual satisfaction and distress for holistic assessment.
How sensitive is the FSFI to medication effects?
The FSFI is moderately to highly sensitive to sexual side effects of medications, particularly SSRIs (which may lower arousal/orgasm subscales). Studies show FSFI subscales improve after dose reduction or medication switching. However, response varies individually; not all patients on SSRIs show decreased FSFI scores.
