How does age affect fertility pregnancy?
In women, age is the most important factor in determining fertility. A baby girl is born with around 1 million eggs; by puberty this ovarian reserve is down to less than half that number, and in the course of her reproductive life a woman will release only around 400 mature eggs. About 15 years before the menopause (from about the age of 35) her ovarian reserve declines further and the quality of her eggs is reduced. In some months an egg may not be produced at all. Despite all the medical advances in recent years, a woman cannot delay the age at which she reaches the menopause and therefore the age at which her fertility starts to diminish.
On pages 16 and 17,1 provide more information on the so-called biological clock and on a woman’s chance of conceiving at every stage of her reproductive life. I also explain the significance of the male partner’s age in how fertile a couple is likely to be. This is important because we now know that in around 40 per cent of cases infertility is due to the male partner, and in a high proportion of those, age is the main factor.
It is easy to dwell on the negative aspects of age and to become demoralized by the statistics, but if age is likely to be an issue for you, stay positive -1 regularly see and successfully treat many women over the age of 35. Bear
If you think either you or your partner have a fertility problem, consult your doctor now in mind that, on average, it takes between 6 and 12 months to conceive across all couples, regardless of age.
I also believe that there is a lot you can do to make sure you give yourself the best chance of becoming pregnant. For example, lifestyle and nutrition have an influence on fertility, and these are discussed in detail in Steps 5 and 6.
However, if you are over 35, and you have been having targeted intercourse for more than six months, you should consider having some fertility tests to rule out any underlying problems.
