Zinc - the big one - it basically doubles your sperm supply
Nitric Oxide - also used to increase your sperm supply
Calcium - thickens and whitens your sperm
Tribulus - increases your horniness
Saw Palmetto - increases your horniness
DHEA - artificial testosterone derivative for hardon strength

Protein Powders and Drinks help as well but they tend to bloat you if you drink/take too much.
