Abstract
Summary
1. 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 were recorded among the wives of 2 of the control subjects.
4. It appears that amino acid therapy for oligospermia should be reserved for those patients who exhibit or give the history of inadequate protein intake.
