It is a commonly accepted fact that when the age of a woman increases, her chances of carrying out a full term of pregnancy decreases. It is said that once a woman advances out of her 20s her chances of becoming pregnant and giving birth begin to slightly decrease, but once she then advances out of her 30s and into her 40s her chances become sharply slimmer... In the same breathe it is important to also recognize the undeniable fact that as age increases the chances of birth defects also increases. These are all very real reasons why some women do not get pregnant, but what are the reasons behind these facts?
One of the main contributing factors is that when a woman advances in age, her ovulation cycle is not as regular as it was when she was younger. By this I mean that her ovulation schedule may move from consistent to sporadic and unpredictable, thus making conception increasingly difficult. The age of a woman’s eggs also play a big factor in whether or not she will be able to carry a baby and give birth. This is because that as the eggs age they simply grow to resist fertilization more and more. And even if an old egg is fertilized, the old age may cause a miscarriage.
