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

As PCRM Edmonton has just opened, we are not able to post our statistics and pregnancy rates.  Our lab systems and operating procedures as well as clinical protocols are identical and we anticipate having the same excellent pregnancy rates that we have in Burnaby.  As we get more data with statistical significance, we will be updating this page.

Below are someIVF Pregnancy Results achieved in our Burnaby Clinic for June 2012 to June 2013.

IVF Pregnancy Results Statistics

Elective Single Embryo Transfer (eSET)

In certain patients, electively transferring one embryo provides excellent pregnancy rates, and significant reduction in multifetal pregnancy. At PCRM, we have strict criteria for electively choosing a single embryo:

  • age under 35
  • no prior failed IVF/ICSI treatment
  • high quality day 5 embryos
  • surplus embryos to permit cryopreservation

In this subset of women, eSET pregnancy rates were 61% in 2012 at PCRM. This represents one of the highest eSET rates in Canada. Other patients who do not fall into these criteria also elect to have a single embryo transfer. Any single embryo transfer is done with consultation between the embryologist, our clients, and our physicians, in order to review risks, benefits, and potential outcomes.

Comments

At PCRM we have a pregnancy rate of 58% for women under age 35, and 54% overall pregnancy rate for all women under 42, which is amongst the best in the country. By comparison, the Canadian national average pregnancy rate per cycle for women under age 35 in the 2009 publication by the Canadian Fertility Andrology Society (CFAS) is 45%, and the pregnancy rate for all women is 36%. The most recent CDC (US) update (2007) also shows a US national pregnancy rate for all women of 35%. These statistics are prepared through the Canadian Assisted Reproductive Technology Registry every year and published to clinics.

Day 5 Embryo transfer

At PCRM, we consistently deliver extremely high ability to transfer embryos on day 5. The ability to grow blastocysts (advanced stage embryos) provides the embryology scientist a more accurate way to select the best embryos, and day 5 embryos also have higher rates of implantation. This allows us to transfer more healthy, but lower numbers of embryos.

Pregnancy rate per Egg Retrieval

When reviewing statistics, it’s important to ask the question about how many cycles get cancelled prior to egg retrieval or embryo transfer. The key number to sort this out is the Pregnancy rate per Egg Retrieval (rather than per cycle started). We have a very low cancellation rate due to a proven track record of experienced decision making, and careful protocol selection.
