Female menstrual cycles synchronised

If you are studying biorhythms as part of your Psychology course, you are likely to come across an intriguing piece of research by Kathleen Stern and Martha McClintock that demonstrates how menstrual cycles (an infradian rhythm) may synchronise as a result of the influence of female pheromones.

The Zimbardo myth
