This work examines gender differences in mental health, focusing on men's lower likelihood of seeking psychological support. A critical review of the literature identifies key barriers that hinder men's access to care services, including individual and social factors such as internalized stigma and rigid models of masculinity, as well as structural factors related to the inadequate capacity of services to respond to men's specific needs. The factors and organizational characteristics that an intervention should possess to increase male participation and adherence to treatment pathways are addressed through two main dimensions: (1) professionals' skills and characteristics, and (2) intervention features and approaches. For professionals, essential requirements include solid knowledge of masculinity and gender socialization, awareness of personal biases, and the adoption of direct, validating, and collaborative communication styles. Regarding intervention design, the literature highlights the value of co-design strategies that incorporate the diverse needs of male populations, the utilization of evidence-based frameworks, clear and goal-oriented structures, and the adoption of a strength-based approach that shifts the focus from deficit models of masculinity to a focus on positive functioning. Effective interventions should adapt language to men's perspective, use informal communication, appropriate humor, and involve respected male role models to normalize help-seeking and reduce stigma. Group-based approaches, action-oriented activities, and transparent goal setting are also recommended to enhance participation and adherence. These approaches aim to make mental health services more inclusive and effective for the male population. It is hypothesized that such strategies may encourage men to seek help, improve their well-being, reduce suicide risk, and generate significant social effects, such as the prevention of gender-based violence and the reduction of healthcare costs.
