Let’s start by having some straight talk about your penis. Other than our own penis, the majority of us have never seen an erect penis outside of a porno film. So, many of us will feel a little inadequate about the size of our member as we have nothing to compare to.

Most of the time for men, there is no real reason to. The average penis erect length of an American male is around six inches. So if you are that big, or bigger, there is nothing for you need to feel insecure about.

Still, these thoughts of inadequacy may continue to tick at us, like an itch that can’t quite reach. And in return, may even get in the way of your performance in the bedroom, since we feel like there is some standard we are not quite living up to.

So we look for ways to increase our penis size. Penis enlargement pills, like the ones you seen advertised in magazines or on the Internet, may do the trick. But how do they work, and what do they contain?

We all know that when we get an erection, there is an increased penis blood flow. As the spongy tissues of the penis become engorged with blood, they get larger and harder.

Male enlargement pills work in the same way, by improving the amount of blood flow into the penis, thus enlarging its overall size. So what ingredients do these pills have and what do they do?

Here is a list of popular ingredients in leading brands of penis enlargement pills; these have all been deemed safe by government regulators:

- Epimedium Sagittatum (Horny Goat) – increases testosterone;
- Erythroxylum Catuaba – a nerve stimulant used in treating impotence;
- Ginkgo Biloba – used to increase penis blood flow;
- Ptychopetalum Olacoides (Muira Pauma) – a potent aphrodisiac;
- Tribulus and Cordyceps – increase testosterone production.

Although these substances are generally recognized as safe they may have some side effects so exercise some caution.

Other ingredients may include zinc glutonate, which helps improve sperm motility (movement of the sperm) and quality; Terminalia Arjuna (Arjuna) – used to improve cardiovascular health; Musli – a natural aphrodisiac; Shatavari – a natural aid for sexual impotence; and Apigenin – used mainly in cancer treatment, it is also seen to maintain cardiovascular health when taken with a rich source of Vitamin C such as Amla.

But you may want to avoid all sexual enhancement pills containing yohimbine. Yohimbine is the main active ingredient in yohimbe, a traditional African aphrodisiac. Yohimbine is seen to dilate blood vessels in the penis, resulting in an increase penis blood flow.

It may also stimulate parts of the brain concerned with sexual desire. But there have also been reports linking yohimbine to serious side effects such as arrhythmia or paralysis.

Despite the hype surrounding penis enlargement pills, some men say they may not really increase the length of your penis permanently. Rather, the pills act as a form of natural Viagra, acting to increase penis blood flow and temporarily augmenting the size and hardness of your erection. That's why all the best suppliers of penis enlargement pills provide a free disc with penis stretching exercises as well.

If you are looking to increase your penis size without pills you may want to consider penis enlargement exercises or SizeGenetics device that works to stretch your penis naturally.
