2005 IVF Statistics

Posted on May 27, 2006 by Inception Fertility

Pacific Fertility Center is pleased to provide its final IVF laboratory statistics for 2005. (This is the most recent data from our clinic and has not yet been reported to CDC/SART. This data includes undelivered pregnancies. The pregnancies counted as positive include all pregnancies with a clear gestational sac on ultrasound examination. We urge caution when comparing these statistics to that of another center. Be advised that a comparison of clinic success rates may not be meaningful because patient medical characteristics and treatment approaches may vary from clinic to clinic.) Comparing IVF programs by published statistics requires some insight into why programs may or may not be different. We have listed some key points to facilitate your understanding of our statistics. Some factors associated with Pacific Fertility Center statistics:

  1. Pacific Fertility Center does not restrict IVF to only those patients most likely to succeed (a practice which often leads to higher pregnancy rates). Our less restrictive approach is confirmed by our high percentage of DOR patients as described in point #2.
  2. Over the years, PFC has treated a substantial number of IVF patients diagnosed with Decreased Ovarian Reserve, DOR (a basal FSH level of 10 mIU/mL or higher). As reported by SART/CDC, in 2003 and 2004, 28% and 22% of PFC patients, respectively, were diagnosed with DOR.
  3. PFC performs a substantial volume of IVF and ovum donor cycles. This allows for better statistical accuracy of our data, (the fewer number of patients - the less statistically significant the rates become). We feel it keeps all of us well-attuned to the practice of ART.
  4. PFC's non-donor egg success rates with frozen embryo transfers approaches that of fresh embryo transfers. We have had a very strong embryo freezing program for many years and are proud of this. Our patients can avoid high order multiple pregnancies by transferring fewer fresh embryos and successfully freezing the remaining embryos. They may also increase the odds of having more than one pregnancy from a single IVF cycle.
