How long after failing for a year while trying to conceive should we wait before starting fertility treatment?

Now: If you have not been successful in becoming pregnant after one year trying, then it is time to see your gynecologist. In older women, perhaps after 6 months.

Consider it now: If you are not pregnant after one year (6 months if you are over 35) of unprotected intercourse, you should see a gynecologist or a reproductive endocrinologist for an evaluation. Some people who have risk factors for infertility should be seen earlier: eg women with medical problems, irregular periods, endometriosis, previous pelvic surgery or infection, etc.
