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.
