Harvard Health has an interesting publication on Testosterone Therapy. Here’s an extract:

Declining testosterone is a normal part of aging, but is replacement therapy right for you? Here is what you need to know.

Testosterone replacement therapy (TRT) has surged in popularity over the past decade. Millions of older men have turned to TRT to restore hormone levels in hopes of refueling energy and reigniting their sex drive.

Yet TRT remains controversial because of its uncertain benefits and potential health risks. Safety concerns were raised years ago when studies showed a possible association between TRT and an increased risk of cardiovascular disease.

Dr. Frances Hayes, a reproductive endocrinologist with Harvard-affiliated Massachusetts General Hospital, points out that some of these studies had limitations.

“For instance, in one study, TRT doses were much higher than what would usually be prescribed, and the subjects tended to be more frail, with other health problems,” she says. “Other studies showed no evidence of increased risk.”

The latest findings

Recent research has supported this position. A study reported at the 2015 American Heart Association Scientific Sessions involved 1,472 men ages 52 to 63 with low testosterone levels and no history of heart disease. Researchers found that healthy men who received TRT did not have a higher risk of heart attack, stroke, or death.

Furthermore, a study in the August 2015 Mayo Clinic Proceedings showed no link between TRT and blood clots in veins among 30,000 men. “Right now, the jury is still out about TRT’s influence on cardiovascular disease,” says Dr. Hayes.

TRT’s relationship with other health issues is also mixed. For instance, TRT has previously been tied to a higher incidence of prostate cancer, but a study published in the December 2015 Journal of Urology found that exposure to TRT over a five-year period was not linked to a greater risk of aggressive prostate cancer.

The bottom line is that the long-term risks of TRT are still unknown, as many of these studies have limited follow-ups. That does not mean you should avoid TRT. For a selected subgroup of men, the therapy can be a viable option.
