Age has a big effect on the success of IVF treatment. The Society for Assisted Reproductive Technology (SART) indicates in their clinic report that the liver birth average percentages are as follows;
- Women under 35 – 9%
- Women 35 to 37 years old – 2%
In the United States, the upper limit for IVF is 50 years for those who want to carry the baby. The upper limit for donation is 45 years. For those who have frozen their eggs, they have the ability to transfer up to when they become 52 years old.
Most programs in the United States, however, have an age limit of between 42 and 45. These numbers are set because IVF live birth rate for women older than 45 years old is less than 1%.
