L-ARGININE is an amino acid the body uses for a variety of important chemical and cellular processes. . .also Studies show sperm/semen can double.. 500mg daily and (this is important...) 1,000mg 30-40 minutes prior to sexual activity. Like all natural supplements, you must be patient and allow your body's "storehouse" to build-up. This period takes anywhere from 2-4 weeks depending upon the individuals baseline health and metabolic rate.
ZINC OXIDE 80% - Increases number of sperm and sperm motility - One of the nutrients most critical for prostate health. The prostate needs 10 times more zinc than any other organ in the body. It is vital for preventing prostate problems. Unfortunately, 90% of men consume diets deficient in Zinc because most of our food is processed. Irving Bush and Associates at Chicago's Cook County Hospital tested the effectiveness of Zinc supplementation on men with prostate problems. All patients reported symptomatic improvement while almost 80% had palpable shrinkage of the prostate gland. RDA is 15 mg...I recommend 45 mg per day..
LYCOPENE - is a natural anti-oxident that is prevalent in tomatoes. Recent studies show it to have roughly twice the power of Beta-Carotene and 10 times the strength of Vitamin E, when it comes to protecting and healing our bodies from the damage of free radicals which are the cancer precursors. In fact, free radicals are now considered to be one of the main causes of disease and aging. In a process known as oxidation, they accelerate the breakdown of our cell's structure, thereby damaging the DNA and weakening our immune system. A four year study at Harvard University set out to see whether the five major antioxidants found in fruits and vegetables would have any beneficial effect on prostate cancer. Of the five, only Lycopene was found to have a direct link. They found that of the 50,000 healthy males studied, those who ate at least 10 servings of tomatoes or tomato based products per week were 33% less likely to develop prostate complications than those who never ate them. Researchers concluded that the active antioxidant in tomatoes, Lycopene, significantly reduced the risk of prostate difficulties and improved its function. I recommend you take 10-12 servings of tomatoes or tomato based foods per week.
BETA-SITOSTEROL - is another nutrient that may benefit men with prostate problems. One double blind study of 100 men showed that Beta-Sitosterol taken over a six-month period improved urine flow, reduced the size of the prostate and led to improvement in the erections and volume of ejaculate.
NIACIN - is important for many cellular processes. Supplementation with extra niacin in your diet will promote increased blood flow to all parts of your body. . .including the scrotum and testicles.
L-LYSINE - Works with zinc to increase sperm produced.
L-CARNITINE - Proven to increase sperm quantity and quality.

Interesting reading. Now, can you tell me how to make it so that I can lower the possibility of me getting a girl pregnant (without having to resort to abstinence or condoms).

Word of caution about NIACIN. Consult your doctor beforehand.
