The Testosterone Dilemma - Men's Journal
Researchers have long known that testosterone, the hormone that confers masculinity, declines naturally with age — about 1 percent per year after you hit your mids, — taking your muscle mass and libido with it. But emerging evidence suggests that men have less testosterone today than their fathers did, most likely owing to increasing rates of obesity and possible exposure to environmental toxins.
Add this to the results of the Northwestern study, and they add up to a grim prognosis for middle-aged men helping their wives raise children in a polluted world. It also adds up to a vast target market for the obvious cure: The sales pitch for TRT reads like a wish list for every man on Earth: No wonder prescriptions for the therapy have jumped percent over the past 18 years.
But while more men are trying TRT, a fierce debate rages among doctors about the safety and ethics of prescribing it to anyone without a defined deficiency.
Before prescribing TRT for hypogonadism, a responsible doctor will recommend lifestyle changes to raise testosterone levels, including weight loss, exercise, and better sleep, says Dr. We treat all of these to improve the quality of life or to increase longevity.
Should we withhold offering prescription glasses to older men and women because poor vision is common with advancing years? Other doctors take this argument even further, advocating that TRT should be used to make men as vigorous as possible, regardless of age.
Jeffry Life , the buff year-old star of many shirtless ads, became the poster boy for the Las Vegas—based Cenegenics Medical Institute precisely because his tremendous physique demonstrates how synthetic testosterone can help men defy expectations of frailty and physical decline.
Testosterone can help change all that. But it could also be argued that Yurth and Life are simply bringing men back up to the testosterone levels enjoyed by their forefathers.
Population-wide, testosterone levels have dropped markedly in the past 20 years — 16 percent in to year-old men, for example. Obesity plays a role, since body fat helps turn testosterone into estrogen. But even when the research is corrected for weight and smoking, it suggests that other factors may be at play — environmental toxins, perhaps.
A study from the University of California, for example, found that atrazine, a common pesticide, is so high in estrogen that it can transform an adult male frog into a fully reproducing female. But others warn that there could be a downside to having high testosterone, and that our bodies lower production for good reasons.
For one, evidence suggests that high testosterone may accelerate prostate cancer. And the Northwestern study makes the point that lower testosterone levels in fathers may be an evolutionary occurrence, helping men become more sensitive and nurturing and, thereby, better dads.
While few doctors doubt that the more testosterone you take, the more muscle you build, some urologists, like Dr. Studies on the relationship between testosterone and heart health have also been mixed. While large studies have shown lower mortality at higher testosterone levels, more recent research has found just the opposite, or that higher testosterone correlates with higher cardiac risk.
One TRT study even had to be halted last year because of an uptick in cardiac events among subjects. TRT has other side effects, too, including shrunken testicles, hair loss, acne, breast enlargement, and sterility.
The therapy can also raise hematocrit levels red blood cell concentration , which in turn can help improve athletic performance. But if your hematocrit level gets too high, the blood can become so viscous that it increases the risk of stroke and heart attack. Your brain sees the level is normal and shuts down.
When hormone replacement therapy was first used with women, it was considered to be very safe…But it became clear that HRT not only increases the risk of certain cancers, it is not beneficial to the heart. For guys without hypogonadism, a wait-and-see approach may make the most sense. Robert Mordkin , a urologist in Arlington, Virginia.
