Male sexual enhancement is a wide topic which covers a large number of aspects of male sexuality.
It is not just concerned about penis enlargement but addresses other problems as well such as impotence, premature ejaculation and fertility problems.
Erectile Dysfunction (ED), sexual dysfunction, is one of the major factors which cause impotency in males.
Erectile dysfunction is more common in men over age 65 but can occur at any age.
It is estimated that in America alone at least 20 million men have some degree of erectile dysfunction.
Actually, virtually all men will experience erectile dysfunction at some stage, resulting from excessive drinking, stress or tiredness.
There is a huge market for all aspects of sexual performance.
In your research for male sexual enhancements, it's pretty sure you have already become acquainted with some of them, such as penis pumps, penis weights, penis rings and the famous penis pills and sex supplements.
This article focuses on some of the common ingredients in natural herbal sexual enhancements and gives you an idea of what these ingredients do.
The goal of most herbal products is to help men increase their sexual performance, stamina and extend their sexual experiences.
What man doesn't want this? One common ingredient is Longjack (tongkai ali / eurycoma longifelio) - a natural Malaysian herb called  the "Asian Viagra".
It is said to have an aphrodisiac effect.
There is compelling research on longjack which shows it as a natural and effective hormone booster.
It naturally boosts testosterone levels.
Another ingredient is Yohimbe.
It is said to stimulate desire causing stronger, longer and more powerful erections via dramatic increases in penile blood flow.
Other ingredients include Maca - a Peruvian botanical with a long history as an aphrodisiac and physical energizer and Gaba.
Some research indicates that Maca has a regulating effect on hormones and increases libido while Gaba - a natural compound can increase the neurotransmitter dopamine.

Male enhancement herbs can aid erections and help sustain erections much longer than normal as well as reducing recovery time between sexual intervals.
They can all work together to bring your body back into a state of harmony and help you enjoy sex even more.
But remember, if you have any questions as to the advisability of taking any product due to a  medical condition, you should always consult your health care professional.
