Success of IVF largely depends on woman's age and her ovarian reserve. The presence of previous failed IVF/ICSI attempts also is an indicator.
IVF is most successful in women who are younger than 35 years of age. In this age group pregnancy rates may be as high as 40% with a single embryo transfer and 55% with a double embryo transfer.
However, pregnancy rates start to decline after 35 and more so after 39. Theoretically a chance of conception beyond the age 45 is zero.
The graphic below displays the clinical pregnancy rate (ultrasound visible pregnancy sac) per embryo transfer in the American Hospital of Istanbul.
As can be seen in this graphic, our clinical pregnancy rate per embryo transfer is approximately 60% at age 24, 47% at age 30 and 40% at age 35.
