Engaging men and boys in the HIV/AIDS response is essential for promoting gender equality, challenging harmful gender norms, and reducing the spread of HIV/AIDS. Gender-transformative approaches seek to transform unequal power dynamics and promote positive masculinities that prioritize respect, equality, and health. By engaging men and boys as allies in the fight against HIV/AIDS, we can break down barriers to access, improve health outcomes, and create healthier, more equitable relationships and communities for all.
