Updating guidelines is a collaborative effort that involves various stakeholders. Professional organizations such as the American College of Obstetricians and Gynecologists (ACOG) or the International Federation of Gynecology and Obstetrics (FIGO) often take the lead in this process. These organizations typically form committees or working groups composed of experts in the field. Additionally, input from researchers, clinicians, and sometimes even patients is considered to ensure that the guidelines are comprehensive and applicable to real-world settings.
