Age & fertility calculator

How does your age affect your fertility?

Based on average statistics, this calculator will give you an idea of how age can affect fertility. Includes the probability of pregnancy each cycle, probability of conception over time, risk of miscarriage and chances of chromosomal defects based on maternal age. The numbers generated by this calculator are simply basic guidelines and can be affected by many factors including the health of both mother and father, as well as weight, ethnicity, environmental influences and emotional health. If you have questions or concerns about your fertility or risks of miscarriage and birth defects, it is best to discuss them with your healthcare provider.

The probability statistics are for women with normal reproductive function only. The numbers represent the "best case" scenario for the probability of pregnancy if you are actively trying to conceive naturally (without any medical intervention).
