Understanding Fertility by Age:
A woman’s fertility naturally declines with age. This calculator estimates the probability of conception per menstrual cycle and cumulatively over several cycles, assuming a healthy couple trying to conceive naturally.
The monthly probability of conception is highest in the early 20s and gradually decreases, with a more significant decline after age 35. This is due to a reduction in both the quantity and quality of eggs.
Key factors influencing fertility:
- Age: The most significant factor for women.
- Ovulation: Regular, healthy ovulation is crucial.
- Sperm Quality: Healthy sperm count and motility for the male partner.
- Tubal Health: Clear fallopian tubes for egg and sperm to meet.
- Overall Health: Lifestyle factors like diet, exercise, stress, and medical conditions can play a role.
These calculations provide general estimates based on population data. Individual fertility can vary widely. If you have concerns about your fertility, or have been trying to conceive without success for an extended period (typically 12 months if under 35, or 6 months if 35 or older), it is recommended to consult with a fertility specialist or healthcare provider.
