Success Rates

We’re proud to have among the highest independently verified success rates in North America.

We do not take our successes for granted! They are the result of years of experience and constant fine-tuning of our stimulation protocols, our laboratory culture conditions and our embryo transfer guidelines. With continued refinements in medication protocols, cycle monitoring, our laboratory environment and techniques we aim to continue to improve our pregnancy rates.

In June 2013, Genesis Fertility Centre was the first Canadian clinic to voluntarily undergo independent verification of success rates by IVF Reports and Fertility Authority, recognized leaders in IVF standards and patient advocacy.

Why are these rates different?

*Biochemical pregnancy rates are defined as positive blood tests done 17 days after the embryo transfer.

**Clinical pregnancy rates are defined as pregnancies confirmed by transvaginal ultrasounds with at least a pregnancy sac present and most often a fetal heart beat.

It is important to ask which statistic is reported at your clinic. Clinical pregnancies are much more likely to result in delivery. After a fetal heart beat is seen, the miscarriage rates usually decrease to 5-10%.

Live birth rate is defined as the birth a child at least 6 months but hopefully 9 months after conception. Annual live birth rates are reported in the fall 2 years later. ( ie for January to December 2010 the reports were published in September 2012.)

eSET: Elective single embryo transfer is defined as single embryo ( blastocyst) transfer in women who have extra embryos available to freeze. The pregnancy rate per eSET measures the quality of an IVF lab and also the commitment of the medical team to healthy singleton births.

What to look for when comparing fertility success results

All fertility clinics post their statistics to the public and to a federal monitoring body (CARTR). When comparing success rates of clinics note how many embryos are transferred back into the woman. High pregnancy rates with fewer embryos replaced is a good sign. If many embryos are transferred back into the woman, there is a risk of a multiple birth which can lead to complicated pregnancies, unhealthy children and family hardship. At Genesis we try to transfer the fewest embryos but still give you the best chance of achieving a healthy pregnancy.

The most important factors determining the success of a cycle are the woman’s age and the number and quality of the embryos we replace. Those factors will vary from one couple to another and from one cycle to the next. Your individual circumstances will be unique. One of our physicians will be pleased to discuss your individual history with you and provide advice that is tailored for you.

Single Embryo Transfer

We are now proud to be perfecting the use of elective single embryo transfer (eSET). This procedure is becoming the gold standard for embryo transfer among eligible women and it is providing outstanding results.

Using eSET we’re able select a single perfect embryo and transfer it into a healthy young woman providing excellent pregnancy rates, while virtually eliminating the risks to mother and child associated with multiple pregnancies.

Nikki was told she could not conceive with her own eggs. One IVF cycle at Genesis Fertility Centre and 2 of her own eggs later, she is mom to Rafe.
