When should couples see an infertility specialist?

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.

Typically 1 year: I believe whenever they are ready. More usually, physicians recommend evaluation after 1 year of unsuccesful trying. When the woman is over 36 years of age, it is nowadays more appropriate to start evaluation after 6 months. I'm glad you asked when a 'couple' can start, both partners should be involved from the very beginning.
