A 28-year-old woman and her partner present to their physician as they have not been able to achieve pregnancy during the past 1 year. Her partner, age 35, and she are both healthy and take no prescription medications. They are sexually active two to three times per week and do not use any contraception. Prior to initiating a potentially expensive infertility evaluation, they ask what percentage of reproductive-age couples are unable to conceive after 1 year of coitus without contraception?
