There are a number of successful natural treatments for erectile dysfunction that are very effective. One needs to examine lifestyle, blood sugar regulation, stress levels, hormone levels, partner issues, confidence issues and energetic flow (Chinese medicine). In a man with normal free testosterone (the male hormone) and blood flow a few simple supplements work wonders. The key is to increase something in the body called NO or nitrous oxide. It is the molecule that changes the blood flow in thepenis that gives a man his erection. This can be accomplished with a number of different things depending on the person. One may simply need pycnogenol and l-arginine. Everyone is different and generally can be helped.
