摘要： During the past decade, national data from Australia and the USA have shown a steady linear increase in pregnancy rates from IVF and ICSI to levels equivalent to those from GIFT. The GIFT rates remained relatively constant at around 21%. The IVF and ICSI rates are similar, indicating that the increase is due more to improvements in the embryo culture procedure than the ICSI technique itself. Pregnancy rates from blastocyst transfer increased nearly two-fold in Australia and New Zealand but appear to have reached a plateau. The adjusted pregnancy rate from non-blastocyst transfer is still similar to that from GIFT. It likely therefore that changes in media formulations and, just as importantly, the culture techniques used have played a major role in contributing to the increased pregnancy rates obtained from ART procedures.
