2019 HIGHLIGHTS OF THE ANNUAL MEETING OF THE EUROPEAN SOCIETY OF HUMAN REPRODUCTION AND EMBRYOLOGY 23rd-26th June 2019 Austria, Vienna The purpose of this report is to capture highlights from the ESHRE 2019 congress. The REPROFACTS faculty has selected the studies presented in this report; putting study findings in perspective and extracting the practice points. The faculty members were independent in their choice of studies and their evaluation and this report is based on the REPROFACTS 2019 Post-ESHRE meeting.

August 2019 GBPMLR/NONF/0819/0199 Sponsored by INTRODUCTION TO REPROFACTS INTRODUCTION TO REPROFACTS The Annual Meeting of ESHRE is considered by many to be the world’s major and most important Faculty members event in the field of reproductive science and medicine. The latest Annual Meeting was held in Vienna, from 24 to 26 June 2019, attracting 12,003 delegates from 130 countries. All relevant innovations Prof. Dr. med. habil. Jürgen M. in reproductive science found a platform for exchange and communication at ESHRE 2019. The main Dr. rer. nat. Jens Hirchenhain Weiss Düsseldorf. Subspeciality: clinical scientific program consisted of 234 peer-reviewed oral communications and 63 invited lectures, with Lucerne. Subspecialities: female infertility embryology an additional 789 posters in electronic format. and ovarian stimulation The key themes ranged from the role of luteal phase support, male infertility and the importance of Prof. Dr. med. Heribert Kentenich Prof. med. Ludwig Wildt Berlin. Subspecialities: safety and quality, counselling the patient, to debates on the increased incidence of ICSI and freeze-all. The ESHRE 2019 Innsbruck. Subspeciality: endocrinology program was truly packed with inspiring content. law and ethics, psychology Priv.-Doz. Dr. rer. nat. Verena However, the wealth and breadth of information can make it challenging for individual delegates to Prof. Dr. med. Michael von Wolff Nordhoff, Bern. Subspecialities: fertility preservation, not only understand the general themes but to also single out and focus on the truly relevant news Münster. Subspecialities: basic science ovarian reserve, early pregnancy from each subspecialty. For that reason, the REPROFACTS initiative was founded in Germany in 2011. and reproductive genetics Eight experts in different subspecialties share among them the whole scientific program of the Prof. Dr. med. Kazem Nouri Prof. Dr. med. Michael Zitzmann Vienna. Subspecialities: endometrium, annual meeting, visiting the lectures, browsing the posters, speaking to the presenters, investigating Münster. Subspeciality: andrology the background and finally selecting what they think represents the “must-know” content from the endometriosis, surgery conference. Nine days after the conclusion of the ESHRE meeting, the REPROFACTS meeting was held in Frankfurt, Germany. The REPROFACTS faculty presented their selection of studies to a large audience of practicing clinicians and embryologists, putting study findings in perspective and extracting the practice points. The faculty is totally independent in their choice of studies and their evaluation. This report contains some of the key highlights from the REPROFACTS meeting 2019.
