This thesis explores the critical role of comprehensive sex education (CSE) in Lebanon, a country deeply influenced by its cultural, political, and religious dynamics. Despite efforts to integrate CSE into the national curriculum, such as the 2009 initiative, societal resistance rooted in a culture of silence has hindered progress. Using UNESCO's international guidelines for CSE as a benchmark, this study critically evaluates the 2009 Lebanese sex education curriculum, identifying gaps and limitations that fail to address the nuanced needs of Lebanese youth. The research highlights how the absence of effective CSE perpetuates gender discrimination, unsafe sexual practices, and stigma surrounding sexuality, especially for marginalized communities. By emphasizing CSE’s transformative potential in fostering informed, equitable, and inclusive societal norms, the thesis advocates for a reformed, culturally sensitive curriculum. This work underscores the urgency of educational reform to break taboos, promote public health, and align Lebanon’s youth with global academic standards.
