Overview

• The study analyzed 35 studies from 2007 to 2024, involving 24,489 participants, primarily from Western countries.
• No significant differences were found in relationship or sexual satisfaction between monogamous and non-monogamous individuals.
• Researchers attribute comparable satisfaction levels to communication, meeting needs, and the absence of infidelity in non-monogamous relationships.
• The findings highlight the stigma faced by non-monogamous individuals and call for more inclusive healthcare, societal, and policy support.
• Limitations include reliance on self-reported data and Western-centric samples, suggesting the need for further research in diverse cultural contexts.
