This largely depends on your age. Although infertility is defined as not becoming pregnant after a year of trying, some couples should be evaluated before one year of trying has passed. If you are less than 35 years old, it is reasonable to try for one year before getting a medical evaluation. However, as a woman ages, her chances of getting pregnant decrease, and an earlier evaluation is recommended.
