Does the probability of pregnancy increase with the number of transfers?

By Guillermo Quea Campos M.D. (gynecologist).

No, pregnancy rates do not increase with the number of embryo transfers. In general, pregnancy rates per transfer in IVF/ICSI cycles are 60% (depending on the age of the patient) with a cumulative pregnancy rate of 90% on the fourth attempt. This does not mean that in the fourth attempt there is a 90% pregnancy rate, but rather that, of all the patients/couples that do IVF/ICSI cycles, 90% of them achieve pregnancy in the fourth attempt, considering that, per attempt, it is 60%.

Similarly, in cycles with donated eggs, pregnancy rates can be 70% with a cumulative pregnancy rate of 99% in a fourth attempt.

It is important to note that, if after a second transfer of good quality embryos pregnancy is not achieved, we must perform a study to determine the cause of the failure (Implantation Failure, etc).
