They get rid of toxins and purify the semen by extracting free radicals. Foods: Oranges, lemon, red and yellow bell peppers, tomatoes are foods that increase fertility.5. Omega-3 Fatty Acids: These are special boosters that when present in the blood increases the blood circulation of the male reproductive organs hence giving energy and boosting potent sperm production.
