At age 65, women are basically menopausal, and the success rate of IVF is extremely low, and it is not recommended to do IVF at this age.
As a woman ages, her ovarian function gradually declines and her estrogen and progesterone levels are significantly lower. Postmenopausal women do not ovulate and are unable to retrieve eggs from their bodies, leaving them with no way to undergo IVF. Even if someone else’s donor eggs are used, the embryos are difficult to develop properly in the body and miscarriages are likely to occur.
Some of the women who are 65 years old have many underlying diseases of their own that make them unsuitable for IVF. Even if there is no disease in the body, the functions of various organs have declined significantly compared to when they were young, and it is difficult to afford the physical changes that occur during pregnancy, making it easy for miscarriages to occur, or complications during pregnancy, such as hypertensive disorders of pregnancy, gestational diabetes, etc., which may jeopardize the life of the pregnant woman and the fetus in severe cases.
