Oysters
Myth has it that oysters are the food of love. Science may agree. Just two to three oyster deliver a full day’s supply of zinc, a mineral critical for normal functioning of the male reproductive system. Scientists are divided over reports that sperm counts have declined over the last 50 years and that environmental factors are to blame. Nutritional deficiencies do seem to be the cause of certain cases of low testosterone. Getting adequate zinc is sometimes the answer (up to 15 milligrams per day is recommended for men; more than 40 milligrams can pose risk). In one trial, 22 men with low testosterone level and sperm counts were given zinc every day for 45 to 50 days. Testosterone levels and sperm counts rose.
