(June 23, 2012) — A new research study finds that a decrease in testosterone levels over time is a lot more likely to result from a man’s behavioral as well as health and wellness modifications than by aging. The research study results will be presented June 25 at The Endocrine Society’s 94th annual satisfying in Houston.
“Declining testosterone levels are Camiseta SL Benfica not an inevitable part of the aging process, as lots of people think,” stated research study co-author Gary Wittert, MD, professor of medicine at the university of Adelaide in Adelaide, Australia. “Testosterone modifications are mainly explained by smoking habits as well as modifications in health and wellness status, especially obesity as well as depression.”
Many older guy have low levels of the sex hormone testosterone, however the cause is not known. few population-based studies have tracked modifications in testosterone levels among the exact same guy over time, as their research study did, Wittert said.
In this study, supported by the national health and wellness as well as medical research study Council of Australia, the authors analyzed testosterone measurements in a lot more than 1,500 guy who had measurements taken at two center gos to five years apart. All blood testosterone samples underwent testing at the exact same time for each time point, according to Wittert.
After the researchers excluded from the analysis any type of guy who had abnormal lab values or who were taking medications or had medical conditions understood to impact Camiseta Arsenal FC hormones, they included 1,382 guy in the data analysis. guy ranged in age from 35 to 80 years, with an typical age of 54.
On average, testosterone levels did not decline substantially over five years; rather, they decreased less than 1 percent each year, the authors reported. However, when the investigators analyzed the data by subgroups, they discovered that specific elements were linked to lower testosterone levels at five years than at the beginning of the study.
“Men who had declines in testosterone were a lot more likely to be those who ended up being obese, had stopped smoking or were depressed at either center visit,” Wittert said. “While stopping smoking may be a cause of a minor decrease in testosterone, the benefit of quitting smoking is huge.”

Unmarried guy in the research study had higher testosterone reductions than did married men. Wittert attributed this discovering to past research study showing that married guy tend to be healthier as well as happier than unmarried men. “Also, routine sexual activity has a tendency to boost testosterone,” he explained.
