The clinical efficacy and acceptance of L-arginina HCL was tested in 40 infertile men. All of these men had a normal number of spermatozoa (> 20 million/ml), but a decreased motility; this decreased motility was not due to infection or to immunological disorders. The treatment consisted of 80 ml of 10% L-arginine HCL administered daily per os for 6 months. L-arginine HCL showed to be able to improve the motility of spermatozoa without any side-effects.
