Players who reported the most concussion symptoms had nearly twice the risk of ED. Notably, those with a few concussion symptoms had elevated risk for low testosterone, which suggests that there may be no safe threshold for head trauma.
Those findings did not change based on the player's position on the field either.
There was never enough noise – we had 10 position category and just did not see any effect, "said Rachel Grashow, the study's lead author.  That ED risk persisted even when researchers accounted for other possible causes for the condition.
ED, hypertension, obesity, cholesterol, depression, anxiety, "said Grashow. "Grashow." [Grashow.]
One of the reasons for this was that the brain's pituitary gland causes problems
That explanation is echoed in previous studies that saw higher ED risks and neurohormonal dysfunction among people with trauma and traumatic brain injury, including military veterans and civilians with head injuries.
The researchers They are observational – based on self-reported concussion symptoms and indirect measures of ED and low testosterone.
"This is definitely a gateway study," said Grashow.
You have not done that, but it has not been done finding.
"The findings suggest that sleep apnea and use of prescription pain medication contribute to low testosterone," said Grashow.
Grashow hopes the findings will help to destigmatize the issue for NFL players and push to get help.
