The likelihood of a 50 year old woman getting pregnant naturally before she has gone through menopause is relatively low, but a very small number of women do get pregnant. A woman develops about 400 mature eggs in her lifetime, and at around age 50 ovarian function has declined or failed significantly, so most women do not have the function to continue having children at this time. Since the ovaries cannot ovulate normally, the probability of getting pregnant is relatively small, and pregnancy is generally not recommended, and the risk of pregnancy is relatively high. But a very small number of 50-year-old women if the menstrual cycle is normal, ovarian function is still in a normal state, in the case of coitus without contraception may also be pregnant, but the probability is relatively small, and is not eugenic age. So although 50 years old, as long as the menopause has not yet, it is still recommended to take contraceptive measures.
