My dissertation studies the provision of reproduction knowledge in school-based sexuality education from a comparative European perspective, with a specific focus on German-speaking countries. Sexuality education is a key channel through which knowledge is transmitted and remains a primary source of reproduction information for the majority of pupils. What is more, people’s knowledge about reproduction plays a crucial role in shaping their reproductive experiences and trajectories. Not least due to this, discussions surrounding sexuality education persist as a significant cultural battleground where debates revolve around notions of sexuality generally, but also around the level of state involvement in the provision of reproduction knowledge.
