Just a few years again, PN co-founder John Berardi, PhD, posted a shirtless photograph of himself on his forty seventh birthday.
He known as it his “anti-regress pic” and thanked 30 years of squats, deadlifts, presses, and chin-ups—amongst different workouts—for his chiseled six-pack, pumped chest, and bulging biceps.
The query many commenters posed:
“Are you on testosterone?”
Dr. Berardi defined in a follow-up put up that whereas he wasn’t in opposition to testosterone substitute remedy (TRT) for individuals who wanted it, he himself was not on this remedy, and his testosterone ranges had been boringly “regular.” He additionally supplied some thought-provoking concepts about testosterone and getting older.

- The mainstream opinion appears to be that declining testosterone is a harbinger of getting older, frailty, and impotence—to not point out a risk to masculinity.
- Rising numbers of middle-aged males are ditching conventional medical checkups for males’s-focused telehealth clinics specializing in testosterone enhancement.1

Are declining testosterone ranges regular?
Do testosterone-boosting complement regimens truly work?

What’s testosterone?
Secreted by the testes, testosterone is the intercourse hormone liable for male sexual traits equivalent to huge muscular tissues, deep voices, and bushy chests. It’s a chemical messenger that performs a key position in numerous processes all through the physique, together with sperm manufacturing and bone density.
(In ladies, who additionally want testosterone to maintain numerous processes buzzing, testosterone is secreted by the ovaries and adrenal glands. Their our bodies simply make a lot much less of it; about 10 to twenty instances lower than males.)
Presumably due to its relationship with muscle development and intercourse drive, numerous cisgender males consider testosterone in binary phrases, with decrease testosterone being unhealthy and better testosterone being good.
Nonetheless, it’s extra correct to consider the connection between testosterone and well being as a continuum that goes from too low (problematic) to too excessive (additionally problematic), with the wholesome vary falling between the 2 extremes, says Denise Asafu-Adjei, MD, MPH, urologist, males’s well being knowledgeable, and assistant professor of urology at Loyola College Chicago-Stritch Faculty of Drugs.

Low testosterone vs. decrease testosterone
Testosterone ranges naturally ebb with age, with most males shedding about 1 to 2 p.c yearly beginning round age 40. By age 75, most males have 30 p.c much less of the hormone than they did at age 25.2
(Enjoyable truth: Between ages 25 and 80, males can count on their testicles to shrink 15 p.c.3)
Nonetheless, age-related drops in testosterone aren’t the identical factor as “low testosterone.”
Hypogonadism is the medical time period for low testosterone ranges, and it impacts about 35 p.c of males older than 45 and 30 to 50 p.c of males who’ve weight problems or sort 2 diabetes, in line with the Endocrine Society, one of many skilled public well being organizations that units hypogonadism remedy tips.
Not solely can overly low testosterone make you are feeling fatigued and do a severe quantity in your intercourse drive, however it may additionally hurt your bone and cardiovascular well being, says Dr. Asafu-Adjei.
“You want testosterone for good bone energy,” says Dr. Asafu-Adjei. “As you grow old, you’re already coping with weaker bones, so having lowered testosterone isn’t going to assist.”
Alternatively, bringing ranges as much as regular appears to supply cardiovascular advantages, she says. (The massive caveat right here is as much as regular—not far above it.)
The significance of referring out
What should you or your consumer have a lot of the hallmark signs of hypogonadism however nonetheless have blood ranges of testosterone within the regular vary?
“Many males over 30 who really feel down or low power will now mechanically blame their testosterone,” says Dr. Asafu-Adjei. “Their signs is likely to be associated to testosterone, however in addition they might be associated to not sleeping, stress, or another issue.”
That’s why seeing a healthcare skilled specializing in males’s well being and testosterone administration is so essential.
Such a doctor can display screen you or your consumer for dozens of different issues (like stress and poor sleep) and situations (like diabetes, weight problems, or sleep apnea) that both mimic the signs of hypogonadism or intervene with the manufacturing or signaling of testosterone.
In different phrases, supplemental testosterone is the reply for some males with signs of hypogonadism, however not all of them. An intensive workup is required.
“There are overlapping signs with low testosterone in addition to numerous nuances round hormone remedy,” says Dr. Asafu-Adjei.
“For instance, exterior of your whole testosterone, we additionally have a look at your testosterone-to-estrogen ratio and different associated hormones. That’s why it’s so essential to go to somebody who is aware of what they’re doing. They’ll take a deeper dive to determine the basis of the issue.”
So, should you concentrate on teaching middle-aged and older males, get a urologist or endocrinologist in your referral community.

Many individuals assume that, in excessive quantities, testosterone turns males into pushy, road-rage-fueled jerks. Nonetheless, the affiliation between the hormone and habits is rather more advanced.4
Because it seems, each an excessive amount of and too little testosterone can result in irritability.
As well as, the hyperlink between testosterone and aggression relies upon so much on somebody’s persona, upbringing, context, social norms, and extra.
For instance, in a single experiment, researchers requested forty younger males to play a online game that concerned accepting and rejecting affords from a proposer. If somebody deemed the proposal too low, they might reject the provide and punish the particular person for making such a substandard ask. Alternatively, in the event that they thought-about the provide useful, they might settle for it in addition to reward the particular person.5
Researchers injected among the males with testosterone as they performed the sport.

The elevated testosterone amplified aggression, but in addition generosity.

They work out so much and watch what they eat. In different phrases, they’re males experiencing mid- to long-term unfavorable power stability.”

If their consuming and train routines counsel they’re in a persistent unfavorable power scenario, he merely recommends they eat an additional wholesome snack or two a day.
“In conditions like this, including a pair hundred additional energy of high-quality protein and carbohydrate usually fixes every little thing,” he says.
These added energy might come from a pair scoops of whey protein combined in milk with a nut butter and banana sandwich on the facet, he says.
One other favourite snack of Dr. Berardi’s: A bowl of steel-cut oats with protein powder, cacao powder, dates, uncooked nuts, and nut butter.

“Mediterranean diets are additionally recognized to advertise coronary heart well being,” says Dr. Asafu-Adjei.

Checking for and treating a mineral deficiency requires the experience of somebody educated in medical diet remedy. For those who lack this coaching, encourage shoppers with low testosterone to speak to their healthcare professionals about whether or not a zinc complement may assist.
Use the Deep Well being lens
Let’s circle again to Dr. Berardi’s speculation, first talked about in the beginning of this story:
Some evolutionary biologists have certainly theorized that males advanced to have larger testosterone ranges after they’re youthful (to encourage mating) and decrease ranges after they’re older (to encourage parenting).19
Nonetheless, that is extra of a concept than a certainty.
What we are able to say with certainty is that this: There’s no one-size-fits-all protocol for wholesome testosterone ranges.
When testosterone drops after center age, some males really feel awful.
Even after they do every little thing proper within the life-style division—exercising, consuming a nutritious diet, sleeping sufficient, and so forth—they’re unable to lift testosterone into the traditional vary. For these males, a healthcare skilled, thorough analysis, and, if warranted, testosterone remedy could be life-changing.
On the similar time, loads of different males proceed to thrive nicely into (and previous!) center age.
Positive, they could be unable to pack on muscle like they used to. However, in the event that they’re paying consideration, suggests Dr. Berardi, they could discover different pluses. Perhaps they’re extra affected person, nurturing, and empathetic, for instance.
“Don’t get me fallacious. I’d be very sad with an inappropriate or clinically vital decreasing of my hormone ranges,” says Dr. Berardi. “Nonetheless, if I can keep within the regular vary and symptom-free with good life-style practices, I don’t suppose I’ve an excessive amount of to fret about.”
Dr. Berardi lately turned 50.
“I’m at this stage the place I see an fascinating fork within the highway,” he mentioned.
“Will I gracefully settle for getting older and see this as a brand new season—or will I combat in opposition to it? I might colour my hair, do hair transplants, high up my T ranges, and get Botox injections. Or I might settle for that there will likely be some eventual decline and ask, ‘What am I getting in return?’”
