IMFER’s Pregnancy Rates in 2012
Below are our statistics on clinical pregnancies for the year 2012. 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, we 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 fourth graphic you can observe that IMFER transfers a lower number of embryos per transfer, which results in a lower number of multiple pregnancies.
