Treatment Success Rates
There are several critical components that determine IVF infertility treatment success rates. These include female age, ovarian reserve and egg quality. At the Montreal Fertility Centre we are dedicated to creating an atmosphere that optimizes your chance of success.
Please note that Quebec law mandates single embryo transfer for all women under age 37, and a maximum of 2 embryos for women age 37 or older.
Our clinical pregnancy rates from January 2013 to December 2017 are listed below. Please note that a clinical pregnancy is defined as having a visible gestational sac at first trimester ultrasound.

The Canadian Fertility and Andrology Society (CFAS) certifies that the format in which this centre presents their IVF data complies with CFAS standards. In doing so, this IVF Centre demonstrates a commitment to clear and easily understood patient communication concerning pregnancy outcomes. CFAS compliance refers to presentation of data only. The data itself has not been audited by the CFAS and remains proprietary to the clinic. Patients should be aware that it is very difficult to compare the results of one clinic with those of another since each has a unique patient population. Many other factors can affect treatment outcomes. Your estimated chance of success with treatment must be individualized to your particular situation and can only be provided once you have had a consultation with the clinic of your choice. The CFAS is a national non-profit multidisciplinary society dedicated to promoting excellence in the field of Assisted Reproduction to the benefit of Canadians and children born of this technology.
