Background: Across societies, gender norms often allow men to hold key decision-making power within relationships, households and communities. This extends to almost all domains, consisting of family planning (FP) as well. FP programs have largely engaged men as clients and rarely as equal partners or influencers although across lower- and middle-income countries (LMICs), and especially in South Asia, men hold key decision-making power on the domain of family planning. The objective of this article is to explore couple dynamics through the lens of spousal communication and decision-making and unpack male engagement and spousal dynamics in family planning. Methods: This review presents a synthesis of evidence from two peer-reviewed databases, PubMed and Jstor, and and insights from programmatic documents to shed light on gender equitable engagement of young married men in family planning. Inclusion and exclusion criteria for both these databases was set and search strategies were finalized. This was followed by title and abstract screening, data extraction, synthesis and analysis. Results: Study participants included unmarried men (16%, n=8), married men (19%, n=9), married women (19%, n=9), married couples (25%, n=12) or more than two respondent categories (21%, n=10). Almost three quarters (71%, n=34) of the studies selected had FP as the primary area of inquiry. Other prominent thematics on which the studies reported were around norms (n=9, 16%), couple dynamics and intimacy (n=12, 22%). Conclusions: The evidence presented provides sufficient impetus to expand on gender-equitable male engagement, viewing men as equal and supportive partners for informed, equitable and collaborative contraceptive uptake and FP choices by couples.
