The probability of pregnancy for women in their 40’s is very low, only 5%. It is very important for women to have preconception checkups because as women age, their ovarian function will gradually degenerate and their fertility will gradually decline. 40-year-old women, in addition to having degenerated ovarian function, may also have thin endometrium and blocked fallopian tubes, all of which may affect their chances of getting pregnant. 40-year-old women may get pregnant as long as they have menstrual flow, which means they have ovulation, but The quality of eggs is not as good as in youth, but pregnancy is possible as long as there is ovulation.
