   Current ART Pregnancy Rates for the Infertility Center of St. Louis

Overall pregnancy rates with the various assisted reproduction procedures performed at our center have consistently been good since the beginning of our program in the 1980s, despite taking on the most difficult cases and rarely canceling cycles.

The following reflects our specific success rates for fresh and frozen transfers. This includes all categories of patients who had transfer of embryos, older and younger patients, good responders and poor responders, unfavorable cases and favorable cases, with no specific selection. We do not cancel cycles because of a low number of follicles or eggs in order to artificially increase success rate reporting.

PREGNANCY RATES PER CYCLE*
(Fresh and Frozen Transfers.)

Procedure Performed Pregnancy Rates
ICSI w/ uterine embryo transfer (ICSI/IVF) 51% (361/711)
Frozen Embryo Transfer (FET) 49% (58/119)



PREGNANCY RATES PER CYCLE*
(By wife's age and ovarian reserve.)

 
Normal Ovarian Reserve
Low Ovarian Reserve
Age Pregnancy   Delivery Pregnancy   Delivery
< 30 years old 64% (108/170)   56% (96/170) 48% (13/27)   41% (11/27)
30-39 years old 57% (183/323)   47% (151/323) 35% (62/175)   27% (47/175)
≥ 40 years old 37% (10/27)   15% (4/27) 20% (5/25)   16% (4/25)

It must be emphasized that lower or higher overall pregnancy rates are not the only determinant of your chance for pregnancy in any specific IVF program. Programs that take on more difficult cases, such as older women, women with fewer eggs, couples with severe sperm problems in the husband, etc., will have lower pregnancy rates than programs that mostly take on "easier" cases, even though they may be higher quality programs.

Many programs either do not accept or cancel women with low numbers of eggs in order to artificially inflate their pregnancy rate. We, however, accept the most difficult cases while maintaining excellent pregnancy rates.

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