According to Verywellfamily, success with an IVF pregnancy is relatively high if you are under 35. Additionally, using donor eggs also increases the chance of IVF success. In terms of percentages, 54.5% of egg retrievals result in a live birth for women 35 and under. This drops to 41.1% for those aged 35-37, and unfortunately severely declines to 26.7% if you are aged 38-40. However, these percentages are based on using your own eggs. A donor egg is not as impacted by the age of the person carrying the baby due to it being implanted.
Conversely, the stats from a 2020 study conducted by Penn Medicine are significantly lower, with the percentage of live births per egg retrieval being 21.3% for women who used their own eggs. This percentage includes babies that were born full term and at a healthy weight. The women carrying were also all 35 and under.
This lower percentage is why many women choose to do multiple cycles of IVF, though it's often an extremely difficult decision to make. As well as being expensive, IVF can cause major stress for those going through the process. In fact, the MGH Center for Women's Mental Health states that those undergoing IVF experience higher levels of depression, anxiety, and feelings of incompetence compared to those who fall pregnant naturally.
