"Forget T Not" from Muscle and Fitness in 2005 lists ten Testosterone-boosting foods: oysters, lean beef, beans, poultry, eggs, lowfat cottage cheese, broccoli, cabbage, Brussels sprouts and garlic. Oysters because of their zinc content are reputed to be a testosterone boosting food. Garlic has shown propensities for testosterone boosting in studies involving rodents, but the dosage needs to be very very high (.8g of garlic per 100g of food). Best bet, avoid alcohol, periodic red meat, get your vegies in every day (broccoli, cauliflowers, cabbage, brussle sprouts), supplement with zinc and/or high dosages of garlic pills....
From doing some research, here is what I came up with as far as the connection between broccoli and testosterone- From "A Man's Worse Nightmare Health Alert 125" by Al Sears, MD.--

http://www.alsearsmd.com/ha125.php"I3C (Indole-3-Carbinol) is a plant compound that has the ability to rid estrogen from your body.3 Vegetables like cabbage, Brussels sprouts, and broccoli contain it. In your digestive tract, I3C converts into DIM.
DIM (Diindolylmethane) is a plant compound that enhances estrogen elimination. It breaks down estrogen into safer compounds. DIM balances the testosterone-estrogen ratio."
