title: Unexplained subfertility: a pragmatic approach.
abstract: The treatment of infertility has made substantial progress over the last two decades. Infertility is said to be unexplained when a couple do not conceive and no definite cause could be identified. Unexplained subfertility continues to pose some difficulty in management principally because of the lack of a specific, and potentially treatable, abnormality and the treatment is generally empirical. In this review, an effort is made to define the current state of the art, efficient and cost-effective infertility care to permit the treatment of a larger number of patients suffering from unexplained subfertility within a reasonable time period.
