This study examined whether the menstruation cycle impacts on suicide. 56 autopsies on Indian females who died by suicide were performed & matched to a control group of 44 females who had died from other causes. Results show that 25% of women of who died by suicide were menstruating at the time, compared to 4.5% of the control group. More research is warranted to investigate this apparent association. There are serious methodological problems in the study of menstruation & suicide & there is a need to understand the impact within a larger psychological, social, & cultural framework. (26 refs.)
