Blog Post: The Impact of Age on In Vitro Fertilization Success Rates
In vitro fertilization (IVF) has become a widely used assisted reproductive technology for couples struggling with infertility. This procedure involves retrieving eggs from a woman’s ovaries and fertilizing them with sperm in a laboratory, before transferring the resulting embryo(s) back into the uterus. While IVF has helped many couples achieve their dream of starting a family, its success rates can vary greatly depending on various factors, such as the age of the woman undergoing the procedure.
Age is a crucial factor in IVF success rates, as the quality and quantity of a woman’s eggs decline as she gets older. This decline in egg quality and quantity can significantly impact the chances of a successful IVF cycle. In this blog post, we will explore how age affects IVF success rates and what couples can do to improve their chances of success.
The Impact of Age on IVF Success Rates
According to a study by the Society for Assisted Reproductive Technology (SART), the live birth rate for IVF using a woman’s own eggs is around 40% for women under 35 years old. However, this success rate drops to 31% for women aged 35-37, 22% for women aged 38-40, and just 12% for women over 40. This significant decline in success rates for older women is due to the natural decline in egg quality and quantity, known as ovarian reserve, as women age.
As women get older, their ovarian reserve decreases, meaning they have fewer eggs available for fertilization. Additionally, the remaining eggs may have chromosomal abnormalities, making them less likely to result in a successful pregnancy. This decline in egg quality and quantity also affects the chances of a successful embryo implantation, which is a crucial factor in IVF success.
Another factor that can impact IVF success rates for older women is the higher likelihood of underlying health issues, such as endometriosis and uterine fibroids, which can make it more challenging for the embryo to implant and grow. These health issues are more common in older women and can significantly impact the success of an IVF cycle.

Improving IVF Success Rates for Older Women
While age is a significant factor in IVF success rates, there are steps that couples can take to improve their chances of success. One option is to consider using donor eggs from a younger woman. By using donor eggs, women over 40 can have the same success rates as younger women, as the quality and quantity of the donor’s eggs are not affected by age. However, this option may not be feasible or desirable for all couples.
Another option is to undergo preimplantation genetic screening (PGS), which involves testing the embryos for chromosomal abnormalities before implantation. This can help identify the healthiest embryos and increase the chances of a successful pregnancy. However, this additional step can also increase the cost of an IVF cycle.
Couples can also improve their chances of IVF success by taking steps to improve their overall health and fertility. This includes maintaining a healthy weight, quitting smoking, reducing alcohol consumption, and managing stress levels. Additionally, women can undergo fertility treatments, such as ovarian stimulation, to increase the number of eggs retrieved for an IVF cycle. However, it’s important to note that ovarian stimulation can also increase the risk of complications, such as ovarian hyperstimulation syndrome.
In conclusion, age has a significant impact on IVF success rates, and women over 40 may face more challenges in achieving a successful pregnancy through IVF. However, by considering alternative options, such as using donor eggs, and taking steps to improve overall health and fertility, older women can increase their chances of success. It’s essential for couples to discuss their options with a fertility specialist to determine the best course of action for their individual situation.
