"Male enhancement" is something of a generalization. Does it mean increasing the size of the penis or just enhancing erections? Or does male enhancement really refer to increasing desire, libido, performance and stamina? Penis size is somewhat predetermined and depends on the size of the corpus cavernosa and corpus spongiosa, as well as the amount of blood flow delivered to fill them. Libido is a complicated matrix of many factors involving circulation, nitric oxide, hormones, psychological factors and overall health.
Testosterone is an androgen or male hormone essential for optimal sexual function. Several ingredients in Enzyte are purported to increase testosterone production. Tribulus terrestris, an herb, has been used by many to increase the lutenizing hormone, which is a messenger that stimulates the production of testosterone in the testicles. Avena sativa or oat straw extract is another libido enhancer said to increase testosterone. Zinc deficiencies have been linked with low testosterone and sperm count.
Nitric oxide (NO) is an important gas that regulates blood flow and circulation in our bodies. It is also one of the reasons that the penis becomes erect. Enzyte contains ingredients that may increase the production of NO in the body. The amino acid L-arginine, found in Enzyte, is a direct precursor to NO. Arginine can vasodilate blood vessels, relaxing them and allowing more blood flow. Horny goat weed or epimedium extract is a traditional herb used for erectile support. The chemical in it, Icariin, also helps with NO production. Niacin (Vitamin B3) is a natural vasodilator, taken to promote healthy circulation. Pine bark extract or pycnogenol may help by decreasing oxidative stress.
Aphrodisiacs are a common phenomenon the world over. Many traditional remedies have little scientific support. However, anecdotal reports indicate that some men see benefits and continue using natural aphrodisiacs. Enzyte contains panax or Korean red ginseng, gingko biloba, maca, muira puama, saw palmetto and Swedish flower pollen. Despite the lack of evidence or understanding of the means of male enhancement, many swear by these herbs.
The ingredients in Enzyte resemble many other male enhancement formulas. Theoretically, they can improve certain factors of male sexual performance. Do they work? Kenneth Goldberg, M.D., medical director of the Male Health Center at Baylor University, says, "It makes no sense medically. There's no way that increasing blood flow to the penis, as Enzyte claims to do, will actually increase its size.” Due to a lack of actual scientific research on Enzyte, it is best to experiment on a trial-and-error basis. Try it and see if you notice any of the benefits that the product claims to provide. It is worth noting that Berkeley Premium Nutraceuticals, the manufacturer of Enzyte, has been sued for allegedly refusing to follow through on its guarantees.
