First off before you read any further penis enlargement pills when taken on their own do not work to make your penis any bigger. Now, if they call them penis enhancement pills there's a good chance they are telling the truth.

Pills do not work on their own but can be effective as a supplement to speed up and enhance the gains from exercises and devices. Penis enhancement pills internally stimulate development of the erectile chambers allowing for more blood to be held, which gives a longer and thicker erection.

When used in conjunction with exercises or enlargement devices as well as enhancing the look of the penis the following benefits have been reported:
o Erection strengthening (hardening)
o Increased sexual stamina
o Increased head size
o More intense orgasms
o Higher sex drive
o Treatment of impotence
o Increased sperm production
o Overall improvement in sexual function
o Increased orgasm intensity.

The ingredients in the enhancement pills are of course important as some pills have no ingredients that will help at all. Some of the most important ingredients to look for (and what they do) are listed below:

L-Arginine is an amino acid that stimulates growth hormone release and improves the immune system. This amazing amino acid totally increases ejaculatory volume levels and orgasm intensity when taken on a regular basis. It is also said to increase sperm production.

The Ginkgo Biloba leaf extract helps with blood circulation and increases the supply of oxygen to the heart, brain and all body parts. In men, it increases the arterial inflow to erectile tissues through arteries and veins without any change to systemic blood pressure.

Panax Ginseng is one of the most popular medicinal plant in China. It is used for mental and physical revitalizing effect on the whole body. Ginseng universally fights weakness and gives more energy. It develops the endocrine gland function and has a good effect on the sex glands. Aside from enhancing athletic performance, Panax Ginseng rejuvenates and increases longevity.

Catuaba is in the area of treating incapacity of the male genital organs. It is an innocent aphrodisiac, safe and highly effective for long term use.

Zinc Gluconate is important for the male reproductive system. Zinc is also essential for healthy prostate function. Testosterone, the most essential anabolic our bodies naturally produce, is recognized to be closely interrelated with zinc.

When choosing an enhancement pill remember to check the ingredients. All good pill sites should contain a list of the ingredients that their pills have in them.

Another point to note is dangerous ingredients. Any pill that contains Yohimbe should always be avoided as it has had a warning placing on it by the FDA.

If you just want your penis to be bigger when you need it, a cheaper alternative is erection or enhancement oils.

Enhancement oils are designed to penetrate the deepest layers of the penile tissue and testicles instantaneously, and give noticeable results within 30 - 90 seconds. The oil is rubbed in a short time before you need it. Because the absorption is direct to the genitals using the transdermal method, 95% of the beneficial ingredients are absorbed, compared to approx 5 to 10% with an herbal capsule or tablet.
