Four original scientific studies of Eugonia have been accepted and will be presented at the forthcoming international congress of the European Society of Human Reproduction and Embryology - ESHRE-2016, to be held in Helsinki on 3-6 July 2016.This is the largest congress worldwide on Assisted Reproduction and as a result only studies of high impact and originality are accepted for publication. This proves that Eugonia continues to be on the cutting edge of scientific research, actively contributing to new developments.The research has been conducted in close collaboration with higher education institutes: Aristotle University of Thessaloniki – Greece, Barts NHS Trust - London, University of Nottingham – UK, University of New South Wales – Australia.Our studies report clinical as well as embryological developments in the field of IVF, and the resulting knowledge will significantly help in improving patient treatment and in increasing our pregnancy rates at Eugonia. Recombinant vs. urinary human chorionic gonadotrophin (hCG) for triggering final oocyte maturation in patients at risk for ovarian hyperstimulation syndrome OHSS: a randomized clinical trialLainas, T.
