Couples are generally advised to seek medical attention if they are unable to achieve pregnancy after a year of unprotected intercourse. The doctors will conduct a physical examination of both individuals to determine their general state of health and to evaluate physical disorders that may be causing infertility. Usually both individuals are interviewed about their sexual habits in order to determine whether intercourse is taking place properly for conception.

If no cause can be determined at this point, more specific tests may be recommended.
