Our results

Institut Marquès has the best results in assisted reproduction. Our success rates are accredited by FIV-CAT, a body that depends on the Generalitat de Catalunya – competent authority in Health matters– and available in their official registry. Institut Marquès participates in the registry of the Spanish Fertility Society (SEF). Below we include the comparison between our results and the average provided by the Spanish Fertility Society (SEF) based on the set of Spanish centers. These data show that Institut Marquès has the best results in the field of assisted reproduction.

For the evaluation of the results it is necessary to take into account the transparency and the safety of each clinic. Our pregnancy rates relate to clinical pregnancy.

At Institut Marquès, we transfer a single embryo in 90% of our treatment cycles. This practice is not usual in other centres. Even so, we are well above the average. We believe that elective single embryo transfer avoids medical risks as well as the possibility of a twin pregnancy.

We are the only Centre where you will be able to see the results of your cycle. The fact that you can watch your embryos live through the “embryoscope from home” allows you to know for sure how many there are, how they are dividing and how is the quality of the transferred and vitrified embryos. Only this way you can really find out. It is an accurate and live report of your results.

Institut Marquès is a leading assisted reproduction reference center that treats patients coming over from 52 different countries.

The figures of patients we treated are reported below:

Average infertility/infertility time: 4, 8 years.
Average number of treatments done in other Centres:3, 6 IVF cycles.

 

In spite of dealing with such difficult cases, we provide the following results:

EGG DONATION

Patients who can freeze embryos after the transfer 85,8%

	Institut Marquès	Spanish Fertility Society (SEF)
Pregnancy / cycle	91%	73,2%
Twin pregnancies	5,0%	20,8%
Average of frozen embryos	2,8	3,3
Average of transferred embryos	1,1	1,6

EGG DONATION
Egg amount (Institut Marquès)

	Average of good quality blastocysts	Pregnancy rate by transfer	Pregnancy rate by cycle
Egg 4	2,1	61,5%	85%
Egg 6-7	3,1	65,2%	91%
Egg +8	3,2	65%	90%

Pregnancy rates mean pregnancies achieved with embryos coming from an egg collection.

This includes the transfer of fresh embryos as well as the possible transfers of frozen embryos.
