ESHRE PGD Consortium data collection XIV –XV: cycles from January 2011 to December 2012 with pregnancy follow-up to October 2013

AbstractSTUDY QUESTIONHow does the data collection XIV –XV of the European Society of Human Reproduction and Embryology (ESHRE) PGD Consortium compare with the cumulative data for data collections I–XIII?SUMMARY ANSWERThe 14th and 15th retrospective collection represents valuable data on PGD/PGS cycles, pregnancies and children: the main trend observed is the increased application of array technology at the cost of FISH testing in PGS cycles and in PGD cycles for chromosomal abnormalities.WHAT IS KNOWN ALREADYSince 1999, the PGD Consortium has collected, analysed and published 13 previous data sets and an overview of the first 10 years of data collections.STUDY DESIGN, SIZE, DURATIONData were collected from each participating centre using a FileMaker Pro database (versions 5 –12). Separate predesigned FileMaker Pro files were used for the cycles, pregnancies and baby records. The study documented cycles performed during the calendar years 2011 and 2012 and follow-up of the pregnancies and babies born which resulted from these cycles (until October 2013).PARTICIPANTS/MATERIALS, SETTINGS, METHODData were submitted by 71 centres (full PGD Consortium members). Records with incomplete or inconsistent data were excluded from the calculations. Corrections, calculations and tables were made by expert co-authors.MAIN RESULTS AND THE ROLE OF CHANCEFor data collection XIV –XV, 71 centres reported data for 11 637 cycles with oocyte retrieval (OR), along with details of the follow...
