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.
|Age Group||<35||35-37||38-40||41-42||43-44||Donor Egg|
|Number of Cycle Starts||44||191||257||111||34|
|Number of Egg Retrievals||420||178||227||89||29|
|Number of Embryo Transfers||390||169||210||82||25||217|
|Average # of Embryos Transferred||1.59||1.78||2.22||2.65||2.84||1.57|
- 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.
