An evaluation for an infertility diagnosis is usually started after inability to achieve pregnancy after 12 months of unprotected and frequent intercourse. People with a past medical history of infertility and women older than 35 years may also choose to be evaluated for a diagnosis. An evaluation usually involves recording the patient’s history (e.g., sexual practices, exposure to toxins or certain medications, surgeries), physical examination and imaging of reproduction organs, and certain laboratory tests (e.g., semen analysis, ovulation hormone levels).[1]
