Abstract

During the past three decades, several reports have suggested that the quality of semen in men is declining. The chance of exposure to environmental toxin tends to increase but most of gonadotoxic agents are not clearly known. We report five patients with secondary transient or permanent reduction of sperm numbers. The possible causes are discussed.
