Question: what are the chances of getting pregnant naturally at 40?
Answer: It depends how far into your 40s you are. At 40, your chance of conceiving is just over 20 per cent (based on the average annual rate of pregnancy per cycle), falling to about 10 per cent by your mid-40s. This compares to 35 per cent for women in their 30s, and 45 per cent for women still in their 20s .
