In Vitro Fertilization (IVF)

Our Pregnancy Rates & Outcomes

While we do not yet have the complete live birth rates for 2014, it is our custom to publish clinical pregnancy rates as soon as they become available each year. Here, we report the fresh IVF cycle outcomes for our program in 2014. For complete pregnancy rates of our program that includes frozen embryo transfers, egg donation cycles and a detailed discussion, please see the main IVF pregnancy rates page.

All the pregnancy rates below are reported with embryo transfer as the reference point, meaning that only the IVF cycles that reached embryo transfer. Some women inevitably experience miscarriages, and live birth rates are expected to be somewhat lower than the clinical pregnancy rates below. As always, our clinical pregnancy rates exclude chemical pregnancies (pregnancies registered only as a spike in hCG levels without ultrasound confirmation).

Interpreting IVF Pregnancy Rates

Here, a few words of caution are in order. Statistical data in medicine should always be interpreted with care, and this is also true in looking at IVF pregnancy rates for a few reasons:

  • Age is not the only factor in infertility, and outcome data based on age alone is not always the best way to estimate an individual patient’s pregnancy chances. One of the other major factors is ovarian reserve.
  • For women with very low ovarian reserve, the risk of “zero” outcome, which is to say no pregnancy chances, is significant.
  • As Society for Assisted Reproductive Technologies (SART) and Centers for Disease Control and Prevention (CDC) also note in their annual outcome reporting, center-to-center comparisons of IVF pregnancy rates can be misleading because of the differences in patient population, treatment approaches and selection criteria.
  • In light of a recent report from CHR that a handful of IVF centers engage in questionable practice of manipulating their IVF outcome reporting in order to inflate their reported pregnancy rates, SART/CDC data should be viewed with caution.

Please visit the main IVF pregnancy rates page, where we discuss our patient population, offer detailed explanation of our latest IVF success rates, and pregnancy rates from other types of treatment cycles, such as FET, egg donation, PGD and so on.
