Your chances of becoming pregnant decrease with age. Research shows that age is becoming a more common factor in infertility because many couples are waiting to have children until their 30s or 40s. People over age 35 have a higher risk of having fertility issues. The reasons for this include:

• Overall number of eggs is lower.
• More eggs have an abnormal number of chromosomes.
• An increased risk of other health conditions. The older a person gets, the greater their chance of acquiring a health condition.
