Understanding Success Rates
IVF programmes do not always use the same criteria to report results. It is important to understand exactly what the numbers mean when looking at percentages. In our hands the following terms apply:
Biochemical Pregnancy: Positive home pregnancy (urine hCG) on Day 16
Clinical Pregnancy: An ultrasound confirmed pregnancy with a fetal heart beat detected.
Results are usually quoted per embryo transfer (ET) and on some occasions per cycle, where cycles refer to egg recoveries.
Rates quoted per embryo transfer and per cycle differ in that the later includes those patients who had egg recoveries but did not subsequently have an embryo transfer. This may have been due to a failed fertilisation, elective freeze or failure to reach the blastocyst stage in a blastocyst cycle.
