Do Women Need Periods? More women in their 20s and 30s are choosing to suppress their menstrual cycles. “Views are changing really rapidly,” E. Micks, MD, says. “That need to have regular periods is not just in our society anymore.” J. Prior, MD, says women should think carefully before trying to suppress their cycle. “Having a period serves a purpose: It tells you your reproductive system is working and that you’re not pregnant. It isn’t a “disease” that needs to be treated away. I think there is value in understanding and appreciating our own intrinsic hormonal cycles. It’s our identity.”
