Clinical pregnancy statistics at Instituto Bernabeu after assisted reproduction treatment

The following data refers to clinical pregnancy rates which end in a live birth and not data commonly provided by many centres which only gives positive pregnancy test rates which unfortunately end in implantation failure or miscarriages.

The statistics refer to one single treatment cycle and was audited by external DNV companies and Instituto Fidelitas.

After three treatments, 90% of our patients become pregnant.

We are committed to preserving maternal health and that of the foetus and so only transfer one or two embryos of high quality. Thus we have achieved high success rates with low rates of multiple births, avoiding the risks associated to both the mother and the children during triplet pregnancies.

In 90% of cycles the embryos reach blastocyst stage (day 4/5 of evolution and transfer), allowing for the natural selection of the embryos. Thus the patient receives the most likely ones to achieve pregnancy.

In 70% of cycles remaining, viable embryos are frozen for future treatments or indeed future children.

Please note that the statistics show global results and should not be applied to individual cases as we should always keep in mind the need to individualise each prognosis.
