Experts say that testosterone levels are crucial for health and well-being.
A study published in The Lancet on Thursday, however, found that men who are exposed to testosterone in early adulthood may experience more problems later in life than men who do not get the hormone in childhood.
Researchers looked at a longitudinal study of over 4,000 people from the United States and Canada and found that people who were exposed to high levels of testosterone during their teens or 20s had higher risk of cardiovascular disease, cancer and prostate cancer in later life.
The study also found that a family history of prostate cancer was associated with an increased risk of prostate and prostate-specific antigen (PSA) levels, a marker of the development of the disease.
This finding may be a result of genetic variation, which has been linked to prostate cancer risk, said lead author Robert W. Johnson, an assistant professor of medicine at the University of Minnesota Medical School.
The findings suggest that exposure to testosterone may be associated with adverse health outcomes later in a man’s life.
Johnson said that the study was conducted to help researchers better understand the role of testosterone in the development and progression of prostate disease.
It also suggests that future research should focus on understanding how to treat high levels in men, Johnson said.
“There is a lot of controversy around this topic.
It’s a matter of doing research to see if we can identify the mechanisms that are responsible for these effects,” Johnson said, adding that more research is needed to understand the link between testosterone and health problems in adulthood.
The United States is one of the world’s biggest producers of testosterone, and testosterone is considered a major component of male reproductive systems.
It is produced by a single cell in the testes, and the hormone is present in all cells in the body.
It is thought to have been responsible for many physiological effects, including the development, maintenance and growth of the testis.
A study published last year found that males who take testosterone are more likely to have lower testosterone levels in adulthood, although this is not clear in a clinical setting.
The American College of Obstetricians and Gynecologists (ACOG) recommends that men begin taking testosterone in adulthood to reduce the risk of developing prostate cancer.
The ACOG also recommends that doctors discuss treatment options with their patients.
According to Johnson, testosterone is a powerful hormone, and it is important to take care of men who take it, including taking a testosterone blocker or testosterone replacement therapy.
He added that the effects of testosterone on prostate health may depend on many factors, including whether the testosterone is taken in the early stages of prostate development or at higher doses.
“A lot of this research has been on men in early life,” he said.
Johnson, however a co-author on the new study, said the findings do not indicate a causal relationship between testosterone exposure and risk of certain health problems.
“This study does not suggest that testosterone exposure is an independent risk factor for cardiovascular disease,” Johnson told The Washington Times.
Johnson noted that it may be possible to reduce or eliminate the impact of testosterone exposure in later lives.
“You can take a very low dose of testosterone and increase the amount of testosterone you take, and there’s probably a small risk,” Johnson explained.
“But what you should do is try to minimize that risk.”
In the meantime, Johnson suggested that men use testosterone-blocking drugs to reduce their risk of heart attacks, strokes and other health problems, particularly in men with higher testosterone levels.
