When to Use

Primary Clinical Uses

Baseline assessment and screening tool for identifying Female Sexual Dysfunction (FSD)

Measuring therapeutic efficacy of interventions (e.g., localized estrogen, ospemifene, flibanserin)

Research standard for quantifying multidimensional sexual function in clinical trials

What it Measures

The FSFI is uniquely potent because it disaggregates sexual function into 6 distinct physical and psychological domains over the past 4 weeks: Desire, Arousal, Lubrication, Orgasm, Satisfaction, and Pain.

How it Works

Scoring Breakdown

The index consists of 19 questions. Each response is scaled, multiplied by a specific domain factor. The maximum total score is 36. Higher scores equal better function.

Clinical Threshold

> 26.55	Normal sexual function
≤ 26.55	Highly suggestive of Female Sexual Dysfunction (FSD)
