Most women in their 40’s can get pregnant. Women in their 40’s have greatly reduced fertility compared to women in their 30’s, but still have fertility functions. Because the average age of menopause for Chinese women is between 44-54 years old, women with relatively normal ovarian function before menopause will have periodic ovulation, so they will be able to conceive, but after the age of 35 years old, women’s ovarian function gradually declines and the quality of eggs decreases, so the chances of conception will be relatively lower. Some women experience a decline in ovarian function around the age of 40 and lose their fertility. If a woman’s fertility function is normal, she is advised to conceive naturally. If a woman’s fertility function declines significantly and the chances of conceiving naturally are low, she is advised to undergo assisted reproductive technology in a timely manner. A small number of women will experience menopause at the age of 40, and these women will lose their fertility due to premature ovarian failure. Pregnant women over the age of 40 need to undergo obstetric diagnosis to ensure the health of the fetus.
