• Several chronic pain conditions, such as temporomandibular disorders (TMD), are more common in women than in men although the biological mechanisms responsible for this gender disparity are poorly understood • Observational studies suggest that TMD pain is greatest during the late luteal phase of the menstrual cycle and during menses when estrogen levels quickly decline • Also, women with TMD who use hormonal contraception report greater levels of daily pain compared to women not taking hormonal contraception • The aim of this study is to evaluate gynecological characteristics that are putative risk factors for TMD: parity, use of hormonal contraception, and self-reported pain levels and psychological symptoms over the course of the menstrual cycle
