Pregnancy after 40 success rate

When couples are trying on their own to get pregnant the fertility issue that reduces chances for success is related to the quality of the eggs. The charts below illustrate the rate of live births per embryo transfer procedure by the age of the recipient of the embryos. Although these age and fertility statistics are specifically about IVF success, there is a similar loss in fertility potential with aging in the general "normal fertile" population. The graphs below are from the 2012 ART Success Rates report published by the CDC, Centers for Disease Control and Prevention, a US government agency.
Another point shown here is that there not a substantial decline in success by age of the recipient woman with donor egg IVF.


The national summary (as well as clinic specific results) of IVF success rates for cycles done in years 1995 through 2012 are posted on the CDC website.
All clinics have some upper age limit after which they will not perform in vitro fertilization with the woman's own eggs.
They also have substantially lower success rates with fertility treatments including in vitro fertilization (IVF). With treatments such as IVF, the issue that holds back success potential is both egg quality and egg quantity. The rate of chromosomal abnormalities in eggs (and therefore also in embryos) increases significantly with advancing female age.


Embryos that have normal chromosomal analysis after PGS have a very high potential for implantation and live birth.
