A prospective study analyzing 30 men who were diagnosed with ED for more than 6 months were treated with a course of 40 hyperbaric oxygen (HBOT) sessions. The results of this study showed remarkable benefits, even for those men who previously were unsuccessful in achieving erections! After HBOT, 63% of the men had none to mild erectile dysfunction. In addition, both penetration and maintenance of erections improved significantly — 24 of the 30 men (80%) reported improved erections. Furthermore, 7 participants who agreed to undergo penile perfusion MRI pre and post HBOT allowed the researchers to conclude: “HBOT reverses the basic common pathophysiology, atherosclerosis and decreased penile perfusion, responsible for most cases of ED” <view study>
