IMFER’s Pregnancy Rates in 2014

Below are our statistics on clinical pregnancies for the year 2014. These are the results of transferring 1 or a maximum of 2 embryos per attempt – even if the law allows for a maximum of 3, IMFER do not recommend the transfer of 3 embryos in any case.

In order to interpret the results correctly, you should bear in mind that:

  • The results refer to clinical pregnancies observed on a scan resulting from a single treatment. Biochemical pregnancies are not included, i.e. those cases where, despite a positive pregnancy test, no gestational sac was observed on the scan.

  • These rates refer to a heterogeneous group of patients with several and varied fertility problems so they cannot be individualized. Each couple is unique and therefore has their own pregnancy chances.
  • In a 70% of cycles supernumerary embryos are obtained, which are cryopreserved for future treatments.

  • Finally, we are including the data obtained by the latest activity register published by  Spanish Society of Fertility (SEF), where you can compare the activity and results of the main fertility clinics in the country with ours.

Here are the results we have obtained:

The cumulative pregnancy probability in a treatment cycle after fresh and frozen embryos transfers raises the probabilities of success up to 60% with IVF-ICSI-IMSI and 85% with egg donation

Multiple pregnancy and ovarian hyper-stimulation (OHS) are the main serious risks that should be -if possible minimized or rather, eliminated. IMFER makes responsible, personalized proposals to reduce the incidence of both complications as much as possible. In the following graphic you can observe that IMFER transfers a lower number of embryos per transfer, which results in a lower number of multiple pregnancies.

Regarding ovarian hyper-stimulation (OHS), for several years we apply specific customized stimulation protocols to prevent it from occurring. Besides, thanks to our excellent embryo cryopreservation program, we have maintained and even improved success rates with patients at risk of ovarian hyper-stimulation so that we have almost eliminated the occurrence of this syndrome. Thanks to the so called “delayed embryo transfer”, we can transfer embryos to an improved uterine setting without a risk of ovarian hyper-stimulation and with high success rates (72% per cycle). For the fourth consecutive year, the number of patients with moderate-severe OHS has been 0.

“Again in 2014, the number of patients with moderate-severe OHS at IMFER has been 0”

For all these reasons, 9 out of 10 patients who do the indicated treatments see their dream of becoming parents come true
