Researchers from the University of Adelaide in Australia say dips in testosterone levels among aging men are more common for those who are depressed or have recently quit smoking. Lead researcher Dr. Gary Wittert presented the findings this month at the Endocrine Society's 94th annual meeting in Houston.
For the study, researchers examined 1,500 men between the ages of 35 and 80. They sampled their testosterone levels in two clinical visits taking places five years apart. The researchers found for most men, testosterone levels dipped only one percent in five years, but some men had more significant drops.
"Men who had declines in testosterone were more likely to be those who became obese, had stopped smoking or were depressed at either clinic visit," Wittert said in a statement. "While stopping smoking may be a cause of a slight decrease in testosterone, the benefit of quitting smoking is huge."
