IVF Pregnancy Success Rates
Successful pregnancy rates from IVF can be defined in several terms. The most
useful and meaningful is the live birth rate or “take home baby rate”. This takes into account that with any couple that
becomes pregnant (either naturally or with the use of fertility treatments) there
is a risk for miscarriages or early pregnancy loss which can range from 10% or
higher depending on factors such as age of the female and history of repeated
miscarriages in the past. Another useful definition of success would be the clinical pregnancy rate which is defined as the presence of a fetal heart beat by ultrasound usually
performed at 6 to 7 weeks of pregnancy. This quoted rate is usually higher than
the live birth rate due to the possibilities of miscarriages and pregnancy losses.
Piedmont Reproductive Endocrinology Group (PREG) is proud to be members of the
American Society of Reproductive Medicine (ASRM) and Society of Assisted Reproductive
Technology (SART). As members of SART we are required to report our In Virto
Fertilization (IVF) pregnancy success rates annually to the Center of Disease
Control (CDC) and have done so since the inception of our IVF program in 2004.
Please visit their website to view this data; www.cdc.gov/art/ . It is important to note that this published data lags by about 2 to 3 years
since live birth rates are reported and therefore programs have to wait for all
live births from their patients to be recorded for that given year.
In late 2006, Piedmont Reproductive Endocrinology Group (PREG) made changes to
our In Vitro Fertilization (IVF) program that included expansion of our embryology
lab, change in laboratory directorship, changes in embryo culture and development
processes and a transition into more blastocyst (Day 5) embryo transfers. In
general, embryos can be transferred on either Day 3 after fertilization (usually
a 4-8 cell embryo) or on Day 5 (blastocyst stage) depending on the number and
development of embryos formed. Advantages of blastocyst embryo transfer include
the ability to select the higher quality and more developed embryos and transfer
of usually only two embryos in attempt to continue with high pregnancy rates but
decrease the risk of multiple pregnancies including triplets or more. Not all
infertility patients are candidates for blastocyst transfer and consultation with
your physician is recommended.
Since most patients want to know a program’s most recent In Vitro Fertilization
(IVF) pregnancy success rates, we are happy to report our clinical pregnancy rates
for 2007 below. Again, live birth rates are not included since all patients who
conceived in 2007 have not yet delivered (live birth rate). It is also very important
to note that comparisons of individual clinic’s In Vitro Fertilization (IVF) pregnancy
success rates may not be meaningful because patient medical characteristics and
treatment approaches may vary from clinic to clinic.
 The clinical pregnancy rate is the percent of In Vitro Fertilization (IVF) cycles
resulting in a pregnancy with fetal cardiac activity within the uterus at 7 weeks of pregnancy as visualized by ultrasound. Live
Birth data is not available yet for these cycles.
A comparison of clinic success rates may not be meaningful because patient medical
characteristics and treatment approaches may vary from clinic to clinic.
The graph below depicts our Fresh Non-Donor In Vitro Fertilization (IVF) clinical
pregnancy rates by day of transfer.
The clinical pregnancy rate is the percent of In Vitro Fertilization (IVF) cycles
resulting in a pregnancy with fetal cardiac activity within the uterus at 7 weeks of pregnancy as visualized by ultrasound. Live
Birth data is not available yet for these cycles.

2006 In Vitro Fertilization (IVF) Success Rates The graph below depicts Piedmont Reproductive Endocrinology Group’s (PREG) 2006
clinical pregnancy rate per cycle start and live birth rate per cycle start also
known as the “take home baby rate” for every patient undergoing Fresh Non-Donor
In Vitro Fertilization (IVF) in the 2006 calendar year at Piedmont Reproductive
Endocrinology Group.
The clinical pregnancy rate is the percent of In Vitro Fertilization (IVF) cycles
per cycle start resulting in a pregnancy with fetal cardiac activity within the uterus at 7 weeks of pregnancy as visualized by ultrasound.
A comparison of clinic success rates may not be meaningful because patient medical
characteristics and treatment approaches may vary from clinic to clinic.
The graph below depicts our 2007 Fresh Donor Egg In Vitro Fertilization (IVF) cycles
implantation rate and clinical pregnancy rate for all ages.
The clinical pregnancy rate is the percent of In Vitro Fertilization (IVF) cycles
per cycle start resulting in a pregnancy with fetal cardiac activity within the uterus at 7 weeks of pregnancy as visualized by ultrasound. Live
Birth data is not available yet for these cycles.
The implantation rate is the total number of pregnancies (gestational sacs) within
the uterus at 6-7 weeks as visualized by ultrasound, divided by the total number
of embryos transferred into the uterus. In the graph above, the implantation rate
is for all of our 2007 fresh donor egg In Vitro Fertilization (IVF) cycles. Each
patient received two embryos during their transfer.
A comparison of clinic success rates may not be meaningful because patient medical
characteristics and treatment approaches may vary from clinic to clinic. |
