In this episode, Professor Elisabet Stener-Victorin from Karolinska Institute in Stockholm, shares understandings regarding the aetiology of polycystic ovarian syndrome (PCOS) according to the latest research. As a researcher, Elisabet and her team hope to uncover underlying causes of the disease, with the aim of finding better treatments in future. Interestingly, 20 genetic variations have been identified as well as links between androgen exposure in foetal life and epigenetic changes. Tune in to hear more from Professor Stener-Victorin.
