Our research examines the impact of menstruation on fieldwork experiences in natural science disciplines, with a particular focus on how systemic androcentric biases shape working conditions. We conducted a cross-sectional survey with 429 participants—primarily women—to collect both quantitative and qualitative data on the logistical, social, and health-related challenges faced during fieldwork. Key aspects include the availability of menstrual hygiene products in first aid kits, access to adequate sanitary facilities, and the communication difficulties regarding menstrual issues, especially with male supervisors. By linking these findings to broader social and cultural dynamics, our study highlights the influence of patriarchal norms in structuring academic environments and calls for more inclusive and equitable fieldwork practices. Our interdisciplinary approach bridges natural sciences and gender studies, offering a critical perspective on how to improve working conditions and advance equity in research settings.
