Respect the Science

It is important to respect the science and our speakers. We are committed to featuring the latest groundbreaking, not-yet published data at ENDO. We can only do that by assuring our speakers we will have 100% compliance with our recording policy. There is no photography or video recording during sessions unless the presenter specifically states that they welcome photography. Please “Respect the Science” as well as our fellow attendees by not disrupting sessions.
