A comparison of clinic success rates may not be meaningful because patient medical characteristics and treatment approaches may vary from clinic to clinic.

Success Rates for ART procedures can be very confusing. Clinics may report their success rates based on different criteria. When exploring ART programs it is important to know what their statistics include, or do not include. Here are some terms which may be used:

1. Human Chorionic Gondaotropin (hCG) level, is the "pregnancy hormone" that keeps the corpus luteum producing progesterone when conception occurs. It is this hormone that is measured by Home Pregnancy Tests (HPTs). An hCG beta blood test is much more sensitive than an HPT and is generally given 14 days after conception should have occurred.
2. Clinical Intrauterine Gestation is the status when a sac is seen via ultrasound
3. Ongoing Clinical Pregnancy is the status when a sac and heartbeat have been determined and the patient is continuing with a pregnancy.
4. Delivery- is the status of haven given birth.

OTHER WAYS TO REPORT STATISTICS
Success Rates can also be reported using a positive beta-HCG rate. The beta-HCG is determined from a blood test. These rates are initially informative because they give you the most current pregnancy statistics; however these statistics are generally higher than the clinical intrauterine gestation statistics, and both are higher than ongoing pregnancy and delivery statistics.

CNY Fertility Center does NOT report success rates using postive HCG rates. We report success rates using clinical intrauterine gestations, ongoing pregnancies or deliveries, whichever information is most up to date.
