ESHRE PGD Consortium data collection VIII: cycles from January to December 2005 with pregnancy follow-up to October...

The eighth report of the European Society of Human Reproduction and Embryology PGD Consortium is presented documenting cycles collected for the calendar year 2005 and follow-up of the pregnancies and babies born until October 2006 which resulted from these cycles. For the first time, the delivery rates for each indication are presented and also the pregnancy rates for each centre are reported anonymously. Since the first data collections, there has been a steady increase in the number of cycles, pregnancies and babies reported annually. For data collection VIII, 39 centres have participated, reporting on 3488 cycles to oocyte retrieval (OR), along with details of the follow-up on 845 pregnancies and 670 babies born. Five hundred and twenty OR were reported for chromosomal abnormalities, 108 OR for sexing for X-linked diseases, 500 OR for monogenic diseases, 2275 OR for preimplantation genetic screening and 85 OR for social sexing. Data VIII is compared with the cumulative data for data collections I-VII.
