Male infertility in patients with bronchial dilatation is related to the progressive obstruction of the epididymo-deferential loop. When bronchial dilatation is diagnosed early enough, a spermogram should be performed to conserve the quality of the semen before it starts to deteriorate. In cases of excretory azoospermia it is essential to consider the diagnosis of bronchial dilatation and possible mucoviscidosis among the various etiologies.
