Agricultural extension services are pivotal instruments for transferring knowledge and technologies to smallholder farmers in developing economies. Yet decades of evidence indicate that women — who make up a substantial share of the agricultural workforce in low- and middle-income countries — remain systematically underserved by these services. This article presents a critical narrative review of the literature on gender, agricultural extension services, and farm-level outcomes, drawing together evidence across three interrelated dimensions: agricultural productivity, farm income, and women's empowerment. Drawing on peer-reviewed studies published mainly from 2010 onwards, the review examines the nature and scale of gender gaps in extension access, the structural and socio-cultural barriers that drive them, and the differential impacts of various extension modalities — including farmer field schools, digital platforms, and female extension agent deployment — on male and female farmers. The article also evaluates measurement frameworks for women's empowerment in agriculture, including the Women's Empowerment in Agriculture Index and its adaptations. The evidence points consistently to the conclusion that women's restricted access to extension services contributes substantially to observed productivity and income gaps and helps perpetuate cycles of disempowerment. Targeted, gender-responsive extension designs — encompassing group-based approaches, ICT-enabled services, and deliberate female staffing strategies — hold real promise, though context sensitivity and sustained institutional commitment remain essential. The review closes with reflections on persistent research gaps and policy implications, and acknowledges limitations relating to geographic concentration, methodological heterogeneity, and possible publication bias in the underlying literature.
