IVF & Assisted Stimulation Cycle
Overall, roughly 71% of medically assisted fertility cycles fail annually (CDC 2012).
By age breakdown the failure rates increase dramatically as women age:
35 and younger – 60% failure rate
35-37 – 70 % failure rate
38-40 – 80% failure rate (78 on cdc website)
41-42 – 90% failure rate (88 on cdc website) 43-44 –95% and higher failure rate
44 and older – 99%
Success rates for IVF depend on a number of factors, including the reason for infertility, where you’re having the procedure done, and your age.
The CDC compiles national statistics for all assisted reproductive technology (ART) procedures performed in the U.S., including IVF, GIFT, and ZIFT, although IVF is by far the most common; it accounts for 99% of the procedures.
The most recent report from 2009 found:
Pregnancy was achieved in an average of 29.4% of all cycles (higher or lower depending on the age of the woman).
The percentage of cycles that resulted in live births was 22.4% on average (higher or lower depending on the age of the woman.
