Influence of Arginine on Oligospermia

Experimental Biology and Medicine, 1947
Summary1. Eighteen infertile men with oligospermia received 1.8-2.7 g of arginine and minimal amounts of lysine, pyridoxine, and tryptophane in tablet form for 8 months.2. The tendency for sperm concentration to increase was as great in the untreated group as in the treated groups.3. Although no pregnancies occurred in the treated groups, 2 pregnancies
