TUESDAY, Feb. 23, 2021 — Testosterone levels tend to fall in older men, but a new study shows that exercise — and not supplemental testosterone — is the way to rejuvenate the aging male heart.
Australian researchers found that without exercise, testosterone replacement therapy offered patients no improvement at all in cardiovascular health. But exercise alone — absent any testosterone supplementation — did boost arterial function.
As a bonus, exercise also boosted the men’s natural testosterone levels, the study found.
According to study author Dr. Bu Yeap, the bottom line is clear: “To improve the health of arteries, exercise is better than testosterone.”
Yeap, who is president of the Endocrine Society of Australia, acknowledged that “there is a gradual decline in testosterone levels as men grow older, extending into middle and older age.” And that decline is often accompanied by expanding waistlines and a wide array of health conditions.
As a result, testosterone therapy has gained traction, largely in a bid for increased energy and muscle mass. In fact, global sales of the hormone have skyrocketed 12-fold in just the first decade of the 21st century.
That’s not necessarily a good development, Yeap cautioned…
