Women at 60 years of age cannot normally undergo IVF because the ovarian function and uterine environment of a 60 year old woman are not suitable for IVF. Under normal circumstances, at age 60, a woman is completely menopausal and her ovaries are no longer able to produce eggs naturally, so she cannot get pregnant. Even if some women are not menopausal at age 60 and are able to produce eggs, the quality of the follicles will be much lower and the uterine environment is not suitable for pregnancy, so the success rate of IVF is very low. Therefore, women generally cannot undergo IVF at the age of 60. Under normal circumstances, the success rate of IVF is higher when a woman is between 25 and 35 years old, and the success rate of IVF will decrease after 35 years old. After menopause, women lose their fertility and are even less able to undergo IVF.
