What this trial studies

This study is a randomized, double-blind, placebo-controlled trial that evaluates the effects of health and wellness products on sexual health and related outcomes in women. Adult participants residing in the United States who express a desire for improved libido, sexual satisfaction, or function will be enrolled. The study will collect self-reported data electronically over a 7-week period, with assessments at baseline, during the study, and at the end. Participants will not know whether they are receiving the active product or a placebo until the conclusion of the study.

Why it matters

Potential benefit: If successful, this study could lead to improved sexual health and satisfaction for women seeking enhancement in these areas.

How similar studies have gone: While similar studies have explored health products for sexual health, this specific approach is relatively novel.
