We didn’t divide by age group, but only by surrogate and self-patient. The success rate is for “Transfer- result in Heartbeat”.
Please note that the majority of pregnancies survive from heartbeat to live birth.
2016 Success Rate is lower than in 2015
In order to avoid “twins or multiple” risk, we are transferring 1.5 embryos each time, lower than 1.9 in 2015.
Higher percentage of Chinese patients who are older and have more challenging health issues (ovary reserve issue, uterus issue, etc.) which skewed down the transfer success.
Note: To keep the integrity of the data, we include all numbers for eggs retrieved. For all eggs and embryos, some are chosen to be frozen, some choose not go through PGS. So, our PGS number and blastocyst Embryo don’t include those cycles.
