It is a process as old as humanity itself, yet there is still much we do not know about women's menstrual cycle and the impact it has on the entire body. Now, a team of researchers from the Department of Clinical Medicine at Aarhus University has, for the first time, demonstrated that the cycle affects a wide range of proteins in the female body, explains Associate Professor Jonas Ghouse, one of the researchers behind the study. The study is published in the journal Nature Medicine.
