Women’s fertility from the 30s to menopause
The most fertile and reproductive women’s age goes between the 20s and the 30s.
Fertility from age 30 is gradually decreasing being more pronounced from age 35 onwards.
- A 30-year-old woman, healthy and fertile, has a 20% probability of pregnancy. This means that 2 out of 10 cycles of attempt to become pregnant can achieve success (we understand cycles of attempt to become pregnant as all sexual relations with a reproductive purpose that take place during the fertile days of menstruation).
- At age 40, women’s probability is lower than 5% per attempt; therefore, less than 0.5 out of 10 cycles of attempt is expected.
- The average age of menopause is age 51, but the majority of women become incapable of becoming successfully pregnant around age 45. These percentages are valid for natural conception.
- For assisted reproduction treatments the rates of success are also affected by age as the quality of the ovum is present according to age. Age-related loss of female fertility is due to the fact that the quality as well as the quantity of ova decrease gradually.
It is a gross error to think that women are fertile until menopause
24% from 22 to 30
20% from 30 to 35
10% from 35 to 40
