Blunted Testosterone Response linked to PTSD

Men whose Testosterone levels fail to rise when stressed are at higher risk of developing Post Traumatic Stress Disorder. A news article on a recent study says:

UT Austin researchers used hormone data obtained from saliva samples of 120 U.S. soldiers before deployment and tracked their monthly combat experiences in Iraq to examine the effects of traumatic war-zone stressors and PTSD symptoms over time, according to university officials.

Before deployment, soldiers’ stress responses were tested in a stressful CO2 inhalation challenge, Josephs said: “Healthy stress responses showed a strong cortisol increase in response to the stressor, whereas abnormal stress responses showed a blunted, nonresponsive change in cortisol.”
The upshot: Soldiers who had an abnormal cortisol response to the CO2 inhalation challenge were more likely to develop PTSD from war-zone stress, scientists concluded. Conversely, soldiers who had an elevated testosterone response to the CO2 inhalation challenge were not likely to develop PTSD, regardless of the soldiers’ cortisol response, according to scientists.

Only the abstract of the journal article is online.
