An extract from the bark of the French maritime pine tree, combined with L-Arginine aspartate, an amino acid, is the natural answer to enhancing erectile quality, say the makers of a new over-the-counter erectile dysfunction product. The supplement, called Prelox, is a blend of two circulation-enhancing ingredients. Pycnogenol (the bark extract), which helps keep blood vessels dilated for optimal blood flow, and L-Arginine, an amino acid.
A study that reviewed the effects of Prelox found that it caused a markedly increased nitric oxide production, the key mediator involved in expanding arteries for elevated blood flow during erections. Conducted by the Medical University of Sofia, Bulgaria, the researchers involved said that by the end of the study, all men taking Prelox experienced almost a 100 percent increase of orgasmic function, sexual desire, intercourse satisfaction and overall satisfaction.
Blood analysis revealed an increased testosterone level during supplementation with Prelox. This is not a direct result of the supplement but is typical for men with increased sexual activity. The men in this trial reported a dramatic increased frequency of morning erections. Moreover, their partners noted a higher interest for sex as well as better performance.
Past research on Prelox indicated its effectiveness in increasing and enhancing sexual performance in three clinical studies in the United States and Europe. In these studies, almost 85 percent of Prelox users said it improved erectile function and more than 70 percent of Prelox users said it was easier to initiate and sustain an erection. In a study at the New York University School of Medicine, more than 80 percent of male subjects rated Prelox as effective in improving their ability to engage in sexual activity.
