With the relaxation of birth policies, many couples are considering expanding their families by having a second or even third child. However, for women of advanced age, the chances of conceiving naturally decrease, leading many to turn to IVF for assistance. IVF, as a product of modern technology, has helped countless families realize their dreams of parenthood. Nevertheless, for older women, the success rate of this technology presents certain challenges.

 

The success rate of IVF is closely related to a woman’s age. Generally, women under the age of 35 have a higher success rate, close to 55%. For women between the ages of 36 and 38, the success rate is around 50%. However, once a woman is over the age of 39, the success rate drops to about 30%. As women age, ovarian reserve and egg quality gradually decline, which affects the formation of embryos and the chances of successful implantation.

 

During the IVF process, ovarian stimulation is used to retrieve more high-quality eggs in one cycle, creating more embryos and thereby improving the success rate. However, studies show that for women over the age of 38, especially those over 40, the dosage of ovarian stimulation medication often increases with age, but the number of eggs retrieved tends to be lower than expected.

 

According to some studies, women of advanced age may need multiple ovarian stimulation cycles to accumulate 8-10 eggs in order to obtain a quality egg for embryo transfer. Even so, the miscarriage rate remains high, and the chances of a successful pregnancy and live birth significantly decrease as age increases.

 

Dr. Nathan Zhang, founder of IVF USA, points out that for women over the age of 40, the success rate of IVF drops dramatically, primarily due to the decline in egg quality. Among 10 eggs, only 1-2 may be of good quality, and the overall success rate is usually less than 1%. Therefore, a single egg retrieval may not be enough for success. It is recommended that women of advanced age undergo multiple egg retrievals to ensure a sufficient number of quality embryos for transfer.

 

Additionally, Dr. Nathan Zhang emphasizes that for older women undergoing IVF, while the number of eggs retrieved is important, the quality of those eggs is even more critical. Even if embryos are formed, it does not guarantee a successful pregnancy or a smooth delivery. Ensuring the live birth rate is the ultimate goal.

 

Before beginning IVF treatment, Dr. Nathan Zhang advises women of advanced age to undergo a thorough fertility assessment to determine whether their ovarian function allows for further attempts. Additionally, maintaining a healthy mindset is key to success. Women should manage their expectations throughout the treatment process and take a rational view of how age impacts fertility.
