Success Rates

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

Clearing up the Confusion
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:

  • 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.
  • Clinical Intrauterine Gestation is the status when a sac is seen via ultrasound
  • Ongoing Clinical Pregnancy is the status when a sac and heartbeat have been determined and the patient is continuing with a pregnancy.
  • Delivery – is the status of having given birth.

How We Calculate Our Reported Statistics

CNY Fertility Center is a member of SART (Society for Assisted Reproductive Technologies), we report all of our data to this agency. All of our statistics are divided into age categories, standard in statistical reporting for ART procedures. Our delivery or on-going pregnancies are from patients that have had an embryo transfer. We take the number of deliveries/on-going pregnancies for each age category and divide that by the number of patients who had an embryo transfer in that age category. In depth statistical information for 2001 and years prior can be found at the Center for Disease Control’s website.

We report pregnancies from PRIDE (donor egg) cycles separately from other patients because the age of the eggs that are donated are not the same as that of the patient carrying the pregnancy, and to include them with non-PRIDE patients would be uninformative. Patients having a frozen embryo transfer (FET) are also calculated separately since the procedure of doing a FET is different from doing a fresh cycle, and should be a distinct statistical entity.

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.
