Success Rates: Statistics
For purposes of the tables below, a "clinical pregnancy" is defined as a pregnancy within the uterus with a fetal heartbeat present at the time of first trimester ultrasound. A small percentage of patients will be expected to miscarry after detection of the fetal heartbeat, especially in the older age groups. Final live birth rate data is presented when available.

Definitions
- Clinical Pregnancy Rates (Clin. PR (+FHB)) - Normal first trimester ultrasound with positive fetal heart beat or normally rising hCG levels, if ultrasound results are not available. Please note that such rates are per embryo transfer.
- Donor Egg - IVF Cycles utilizing oocytes from anonymous or known donors
- Live Birth Rate - Birth of one or more live infants as a result of an embryo transfer
The rates above reflect patients with a variety of different fertility diagnoses and ages. These rates are a combination of both blastocyst and day 3 embryo transfers. A comparison of clinic success rates may not be meaningful because patient medical characteristics and treatment approaches may vary from clinic to clinic.
