The couple must be considered as a single unit as each partner contributes a share to the infertility potential of the couple. The approach to infertility requires an efficient and complete initial evaluation. Many couples have more than one contributory cause which should be identified early in the evaluation.
Evaluation must begin with a detailed history and a complete physical examination of both partners. History-taking must be directed to complete all the items related to infertility. A pre-morbid history should be analyzed in detail concerning the disease, the investigations done, and the treatment. The history and/or physical examination may direct the evaluation in a particular direction, but other pertinent fertility factors should not be overlooked.
