Comparing success rates between egg donation & standard IVF

The following chart, from the Centers for Disease Control, compares the success (measured as a delivered pregnancy) using donor eggs compared to using a woman’s own eggs:

From this table, you can see that using the eggs of young, healthy non-infertile women imparts a higher probability of success at almost all ages where a comparison is possible.

At older ages, the discrepancy is even greater than portrayed in this graph because some women do not get an embryo transfer. The incidence of cycle cancellation and the number of cycles with no embryos for transfer rises with the woman ages when using the woman’s own eggs.

Looking at the table below from 2002 CDC/SART (Society for Assisted Reproductive Technology) national success rates, you can see that the data suggest that donated eggs result in very high rates of delivered pregnancies.

Age	No Egg Retrieval	No Embryo Transfer
<35	9%	5%
35-37	13%	4%
38-40	17%	5%
41-42	20%	7%
>42	24%	11%

Further, because the eggs come from young women, the incidence of miscarriage and births of chromosomally abnormal children like Downs syndrome is lower.

These pregnancies do not require prenatal genetic testing with either amniocentesis or chorionic villus sampling.
