Latest IVF Success Rates in the US

Adapted from Preliminary National Summary Report for 2020 published by the American Society for Reproductive Medicine (ASRM)

The latest available (2020) In Vitro Fertilization live birth rates were recently published by the ASRM.

In 2020, there were 117,384 IVF treatment cycles started in the US. The majority of pregnancies were singleton pregnancies (over 93%), with less than 7% twins and less than 0.5% triplets or more.

Over 85% of pregnancies were term pregnancies, with the remainder either pre-term or very pre-term. This is not statistically different from spontaneously conceived pregnancies.

The probability of a successful outcome depends mainly on the transferred embryo quality, which reflects primarily the quality of one’s eggs. The egg quality, in turn, is, for the most part, dependent on the female age. The following table shows the probability of live birth per IVF treatment cycle (%) related to the female age at the treatment start.

Age 34 & Younger 35-37 38-40 40-42 43 & older
Live Birth Probability 44.6 31.5 19.9 9.7 2.9
Average Number of Embryos Transferred 1.2 1.2 1.4 1.7 2.0
Implantation Rate per Embryo 51.4 45.4 36.1 21.9 8.2

 

There is no available treatment to improve one’s egg and sperm quality. Still, your lifestyle, type of diet, the level of stress in your life, physical activity, and exposure to egg/sperm damaging factors can play a decisive role in your probability of success.
