Menstrual cups have gained significant attention as a sustainable, costeffective, and long-term alternative to traditional menstrual products. These reusable devices, made from medical-grade silicone, rubber, or elastomer, are inserted into the vaginal canal to collect menstrual blood. Despite their growing popularity, concerns have emerged regarding their safety, particularly their potential impact on reproductive health, including the risk of infertility. This study aims to assess the safety of menstrual cups by investigating whether their use is associated with an increased risk of infertility in women.
