What criteria classifies a couple as infertile?

6-12 months: If you believe you have a fertility problem, you should seek out an expert in fertility diagnosis and treatment. In women under 35, common guidance is to try for a year, if you feel you are healthy, before seeking assistance. Over age 35, 6 months. If menstrual cycles are irregular, or you have a medical condition, seek help sooner.

1 year: The simple answer is infertility is defined as 1 year of exposure (unprotected intercourse) without conception. This is based on observing that 85% of couples without fertility problems conceive naturally within 1 year. Actively trying vs. 'not preventing it', ' and other factors such as frequency of trying do not alter the clinical definition. Tests usually help sort out more specifics.
