We organized the webinar “Adenomyosis: An Update 2021” as Turkish Society of Endometriosis and Adenomyosis. Stefano Guerriero, MD (Italy) , Erkut Attar, MD (Turkey) and Miklos Koppan, MD (Hungary) shared their experiences with their presentations in this webinar moderated by Yücel Karaman, MD and Tolga Karacan, MD. We tried to answer many questions with case presentations and interactive discussion sessions. We’d like to thank our dear attendees for their intense interest .
