How Does Age Affect Fertility?

Read Transcript

Infertility is affected by age. We are born with all the eggs that you will ever use in your lifetime. So that means a 35 year old woman who's trying to get pregnant, those eggs are actually 35 years old. So unfortunately at the time of ovulation, all our eggs are actually stopped at what we call miosis which is a stage of division.

When that meiosis is completed, when the egg is fertilized. When we do get older, the chances of it having more mistakes increases. So for example, at the age of 35, our chances of having a baby with a chromosomal abnormality is one in 265, already by the age of 45 it's one in 25 chance of you having a baby with a genetic abnormality.

So you see that age does affect fertility.
