A member asked:

How does the menstrual cycle work in sync w/other women? i heard one's cycle is affected by women surrounding you?

A doctor has provided 1 answer

Likely due to smell: If the definitive answer is known, I am not aware of it. A likely explanation is women responding to each other's odors and perhaps pheromones. One does not have to be aware of the odors for the chemicals to affect a persons hormones.
