Sexual dysfunction is characterized by disturbances in sexual desire and in the psychophysiological changes associated with the sexual response cycle (American Psychiatric Association, 1994). Prevalent in both genders, it ranges from 10–52% of men and 25–63% of women based on several studies (Frank et al., 1978; Spector and Carey, 1990; Rosen et al., 1993). It has been reported that the incidence of sexual dysfunction in the United States is greater in women (43%) than in men (31%) (Laumann et al., 1999).
Advances have occurred in the understanding of the neurovascular mechanisms of sexual response in both men and women (Rajfer et al., 1992; Burnett, 1995; Park et al., 1997). Several new classes of drugs have been identified that offer significant therapeutic potential for the treatment of male erectile disorder (Heaton et al., 1995; Morales et al., 1995; Boolellet al., 1996), while other agents are indicated for sexual desire and orgasm disorders (Rosen and Ashton, 1993; Segraves et al., 1993; Morales et al., 1995). In addition to conventional therapies, however, individuals with sexual dysfunction often seek alternative therapies.
Erectile dysfunction effects 50 percent of men ages 40-70 in the United States and is considered an important public health problem by the National Institutes of Health. Consumers are exposed to a plethora of natural products claiming to restore erection and sexual vitality. A review of the available empirical evidence reveals most naturally occurring compounds lack adequate clinical trials to support efficacy. However, arginine, yohimbine, Panax ginseng, maca, and Ginkgo biloba all have some degree of evidence they may be helpful for erectile dysfunction. Improvements in penile endothelial L-arginine-nitric oxide activity appear to be a unifying explanation for the actions of these naturally occurring agents. (Altern Med Rev 2004;9(1):4-16)
Traditional herbs have been a revolutionary breakthrough in the management of erectile dysfunction and have become known world-wide as an 'instant' treatment. The modern view of the management of erectile dysfunction subscribes to a single etiology, i.e. the mechanism of erection. A large number of pharmacological agents are orally consumed and vasoactive agents inserted intraurethrally or injected intrapenially to regain good erection. Modern phytochemicals have been developed from traditional herbs.
Phytochemicals focus their mechanism of healing action of the root cause, i.e. the inability to control the proper function of the whole body system. Hence phytochemicals manage erectile dysfunction in the frame of sexual dysfunction as a whole entity. Protodioscin is a phytochemical agent derived from Tribulus terrestris L plant, which has been clinically proven to improve sexual desire and enhance erection via the conversion of protodioscin to DHEA (Dehydroepiandrosterone).
Preliminary observations suggest that Tribulus terrestris L grown on different soils does not consistently produce the active component protodioscin. Further photochemical studies of many other herbal plants are needed to explain the inconsistent result found with other herbal plants, such as in diversities of Ginseng, Eurycoma longifolia, Pimpinella pruacen, Muara puama, Ginkgo biloba, Yohimbe etc.
Nitric oxide has been identified as an edothelium-derived relaxing factor in blood vessels. We tried to determine whether it is involved in the relaxation of the corpus cavernosum that allows penile erection. The relaxation of this smooth muscle is known to occur in response to stimulation by nonadrenergic, non-cholinergic neurons.
Methods: We studied strips of corpus cavernosum tissue obtained from 21 men in whom penile prostheses were inserted because of impotence. The mounted smooth-muscle specimens were pretreated with guanethidine and atropine and submaximally contracted with phenylephrine. We then studied the smooth-muscle relaxant responses to stimulation by an electrical field and to nitric oxide.
Just like the diet pill industry and the muscle building industry, the male enhancement industry has its fair share of bad companies that use tricks and deception to pry you from your hard earned money. We have compiled a short list of the most noted scams, tricks and bogus products to watch out for this year.
Nitric oxide makes an erection significantly bigger, harder and stronger by widening blood vessels in the penis. Nitric oxide is produced L-Arginine, an amino acid found in the body. Scientists have recently confirmed that most male enhancement pills made with high-quality L-Arginine can greatly increase erection size, as well as treat erectile dysfunction.
For over a decade, scientists have known that nitric oxide improves erectile function, but it wasn’t until the prescription drug Viagra was introduced that millions of men realized just how special this molecule is.
We have entered an era where talking about sex isn’t taboo. People aren’t afraid to discuss ways to improve their sexual function and erectile problems. All natural sexual enhancers have been around for thousands of years—herbs proven to increase desire and libido are no stranger to hundreds of cultures around the world. Americans like their prescription drugs like Viagra and Cialis, but all natural enhancers are now extremely popular. New technology is pushing sexual pills to the max and within the next five years, sexual supplements are going to be even more effective and powerful.
The future of treatment for erectile dysfunction (ED) is exciting and the potential relationship between erectile dysfunction and cardiovascular disease and risk factors may allow the clinician to save a man's life based upon his erections. It's conceivable that we all may be taking one of these PDE-5 inhibitors in the next decade for prevention and protection from the ravages of aging.
Male enhancement supplements increase penis size and enhance sexual performance—a dream come true for any man! Luckily, there are many all-natural, over-the-counter penis pills to choose from. But, not all men need a male enhancer, while others are in great need of them. Before you purchase a product, first make sure you are a candidate for these powerful supplements.
Sexual health is an important part of your overall health. Everybody wants to be healthy, but many men ignore the importance of sexual health. Usually, this is because they fell embarrassed or because they think there is no solution. Men tend to be ashamed of various sexual problems, but the good news is that these problems are usually physical rather than mental or emotional and there is a solution: male enhancement supplements.
Every man wants a bigger penis so he can be sexually perfect in bed and please his woman. There are thousands of products on the market that not only increase penis size, but also help enhance sexual pleasure. They range from sex pills to penis pumps to penile exercises. They supposedly help treat male sexual problems like erectile dysfunction or impotence, premature ejaculation and low stamina. Sex pills are the most popular, but there are still some myths surrounding their use.
Mostly all the effective sex tablets and supplements increase blood flow to the genitals. There are some natural formulations prepared from the finest extracts of herbal aphrodisiacs like ginseng, ginkgo, muira pauma, L-Arginine and Tribulus Terrestris, which not only increase blood flow to your penis but also help in enhancing low male libido and testosterone levels.
The name says it all—a leafy plant that has been used for thousands of years as an aphrodisiac that increases sexual desire and improves erectile function. It was given its name when a goat herder noticed his goats going on a sexual rampage after eating certain weeds. Today, nearly every natural male enhancer contains this herb.
Known also as Epimedium or Yin Yang Huo, horny goat weed was first described in ancient classical Chinese medicinal texts. Today, horny goat weed holds an important place in Traditional Chinese Medicine and is gaining popularity around the world.
One of the questions we get asked most frequently is: How much longer can my penis get? Men of all ages, nationalities and backgrounds seek to make their penises longer, wider, and harder. Clinicians have identified...
Surprisingly, we have received a number of questions about the male enhancement product Rexavar and it’s association with the actor Charlie Sheen. Penis enlargement companies routinely hire actors and sports stars and other celebrities to endorse their male enhancement supplements. You may have seen Jimmy Johnson the former Dallas Cowboys head football coach appearing in TV commercials for Extenze for example. Other examples of celebrities who have endorsed male enhancement or penis enlargement pills like Rexavar include Jim McMahon, Dennis Rodman, Mike Ditka, Steve O, Ron Jeremy, Bob Feller, Mark McGwire, and many others.
However, Charlie Sheen is not a spokesperson for Rexavar. When we spoke to the people at Rexavar they stated that Charlie Sheen was on the cover of a magazine about male enhancement pills that rated Rexavar number one, and many people have assumed that Charlie Sheen was using Rexavar. The company says they do actually have a number of high profile celebrities that use the product but due to privacy guidelines they would not release the names of any other their clients.
So we can put this rumor to bed – Charlie Sheen is not a paid spokes person for Rexavar or any other male enhancement pill, product or supplement.
Rexavar â€“ The ultimate â€śEnhancementâ€ť pill for men of all ages. The published science behind it sets it apart from the pack.
Longinexx's ingredients are perfectly blended for a synergistic that is second to none. Technology innovations represent the future of male enhancement nutraceuticals.
