IVF Success rates by age

A female’s age plays a crucial role in the success of IVF treatment. According to AIIMS Delhi, the overall IVF success rate lies between 30% and 35%. However, it differs from one female to another and is different in different age groups. It is higher in the 20s and early 30s and starts decreasing in females above 35.

In your 20s, you will have a 20% of pregnancy success if you have no fertility issues. If you opt for IVF treatment due to any infertility issues such as lower egg numbers, genetic disease, etc., your IVF success rates will be different. As per the Centre for Disease Control (CDC), the success rates would be:

• Higher if you are under 35
• 32% if you are under 35 and haven’t conceived before
• 37% if you have had a child and are under 35 and trying to have the second child through ART
• 34% if you have more than two children and are in your 20s
