Success rate statistics for In-Vitro Fertilization (IVF) and Elective Single Embryo Transfer (eSET)

PCRM IVF Pregnancy Results:

Updated January 2017

At PCRM we are proud to report our IVF success rates because they are among the highest in the country. This guide should give you an idea of how IVF statistics are presented. The Canadian Fertility Andrology Society (CFAS) is working to standardize reporting at IVF clinics to make things easier for patients to understand and to avoid misleading or exaggerated statistics. All IVF clinics in Canada report their numbers to Canadian Assisted Reproductive Technologies Register Plus (CARTR).You can find this information here on the CFAS website.

We understand that each patient is unique. So, while these success rates may provide a general guide, your individual chance of pregnancy should be discussed with your doctor. Your chance of success may be higher or lower than our averages. Your doctor will take into account the many factors that influence pregnancy rate:

  • Age
  • Egg number
  • Sperm count and motility
  • Uterine and tubal factors

Clinical Pregnancy

Your success is our goal. One of the most important measures of success in an IVF cycle is clinical pregnancy. This refers to a pregnancy that reaches the point it can be seen on ultrasound (i.e. 6-7 weeks gestational age and beyond).

Cumulative Clinical Pregnancy Rates:

Cumulative clinical pregnancy rate refers to the pregnancy rate resulting from all of the eggs collected in one IVF cycle (one batch). Due to the increasing number of patients who freeze all of their embryos and do not have a fresh embryo transfer, the pregnancy rates over a short interval of time are considered by many to be most representative of actual success rates. Because of the time required to wait for embryo transfer and follow-up of the resulting pregnancy, it takes several months to compile this statistic.

IVF Cumulative Clinical Pregnancy Rate
(< 35 years)
(2014 – 2015, n = 224)
 69%  Canadian Average (2015) = 42%
IVF Cumulative Clinical Pregnancy Rate
(35 – 42 years)
(2014 – 2015, n = 373)
 49%  Canadian Average (2015) = 31%


Donor Egg Pregnancy Rates:

Donor egg pregnancy rate refers to the fertilization of frozen-thawed eggs obtained from an anonymous donor via a commercial egg bank. Warming, fertilization, and growing the embryo occur in our laboratory.

Donor Egg Clinical Pregnancy Rate
(2016, n = 42)
 69%  Canadian average (2015) = 58%


Canadian Average IVF Pregnancy Results:
