Menstrual Synchrony

Menstrual synchrony, also known as the McClintock Effect, or the Wellesley Effect is a phenomenon reported in 1971 wherein the menstrual cycles of women who lived together (such as in homes, prisons, convents, bordellos, dormitories, or barracks) reportedly became synchronized over time. The existence of menstrual synchrony has not been definitively established, and studies investigating it have been controversial. The phenomenon of menstrual synchrony also addresses the larger question of whether or not humans have and can perceive pheromones, or utilize chemosignaling.
