Former football players who had experienced more severe concussions were more likely to report erectile dysfunction and low testosterone than other players. Published in JAMA Neurology, researchers used self-reported data about treatment for ED and low testosterone in 3,409 former players. More than 18% of the players reported low testosterone levels, 22.7% reported erectile dysfunction, and both rates rose in association with head trauma. Fewer than 10% reported undergoing treatment for both symptoms.
“We found a very strong association between number of concussion symptoms and the likelihood that a former football player reported erectile dysfunction, or reported low testosterone. As you increase the number of reported concussion symptoms, you see a subsequent increase in likelihood of ED or low T.”
