Just a few years again, PN co-founder John Berardi, PhD, posted a shirtless photograph of himself on his forty seventh birthday.
He referred to as it his “anti-regress pic” and thanked 30 years of squats, deadlifts, presses, and chin-ups—amongst different workout routines—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 publish 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 have been boringly “regular.” He additionally supplied some thought-provoking concepts about testosterone and growing old.
Dr. Berardi’s take is the other of what you typically hear, particularly as of late when…
- The mainstream opinion appears to be that declining testosterone is a harbinger of growing old, frailty, and impotence—to not point out a menace to masculinity.
- Rising numbers of middle-aged males are ditching conventional medical checkups for males’s-focused telehealth clinics focusing on testosterone enhancement.1

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

On this story, we’ll discover these questions and extra.
What’s testosterone?
Secreted by the testes, testosterone is the intercourse hormone accountable for male sexual traits akin to large muscle groups, deep voices, and furry chests. It’s a chemical messenger that performs a key position in varied processes all through the physique, together with sperm manufacturing and bone density.
(In girls, who additionally want testosterone to maintain varied 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, a whole lot of cisgender males consider testosterone in binary phrases, with decrease testosterone being dangerous 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 College of Medication.

Low testosterone vs. decrease testosterone
Testosterone ranges naturally ebb with age, with most males shedding about 1 to 2 % yearly beginning round age 40. By age 75, most males have 30 % 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 %.3)
Nonetheless, age-related drops in testosterone will not be the identical factor as “low testosterone.”
Hypogonadism is the medical time period for low testosterone ranges, and it impacts about 35 % of males older than 45 and 30 to 50 % of males who’ve weight problems or kind 2 diabetes, in accordance with the Endocrine Society, one of many skilled public well being organizations that units hypogonadism therapy tips.
Not solely can overly low testosterone make you are feeling fatigued and do a critical quantity in your intercourse drive, however it could actually 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 become 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 large caveat right here is as much as regular—not far above it.)
The significance of referring out
What for those who or your shopper 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 routinely blame their testosterone,” says Dr. Asafu-Adjei. “Their signs is likely to be associated to testosterone, however additionally they could possibly 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 vital.
Such a doctor can display you or your shopper 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 intrude 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 in depth workup is required.
“There are overlapping signs with low testosterone in addition to a whole lot of nuances round hormone therapy,” says Dr. Asafu-Adjei.
“For instance, outdoors of your complete testosterone, we additionally take a look at your testosterone-to-estrogen ratio and different associated hormones. That’s why it’s so vital to go to somebody who is aware of what they’re doing. They’ll take a deeper dive to determine the foundation of the issue.”

Testosterone and aggression
Many individuals assume that, in excessive quantities, testosterone turns males into pushy, road-rage-fueled jerks. Nonetheless, the affiliation between the hormone and conduct is way more complicated.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 lots 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 presents from a proposer. If somebody deemed the proposal too low, they may reject the supply and punish the individual for making such a substandard ask. Alternatively, in the event that they thought-about the supply useful, they may settle for it in addition to reward the individual.5
Researchers injected a number of the males with testosterone as they performed the sport.
As anticipated, gamers handled with the hormone have been extra prone to punish proposers, particularly in the event that they thought-about the supply unfair. Nonetheless, in the event that they perceived the supply as truthful, they rewarded the proposer extra generously.
The elevated testosterone amplified aggression, but additionally generosity.
Some researchers discuss with this phenomenon as “the male warrior speculation,” which holds that testosterone could perform to assist some males defend and cooperate with their “in group” (akin to their household, mates, and coworkers) whereas concurrently punishing anybody seen as an outsider.6

They work out lots and watch what they eat. In different phrases, they’re males experiencing mid- to long-term unfavourable power steadiness.”
Dr. Berardi’s recommendation is commonly not what males count on.
If their consuming and train routines counsel they’re in a persistent unfavourable 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 thing,” he says.
These added energy might come from a pair scoops of whey protein blended 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.

As you sleep, ranges rise once more, peaking throughout your first section of speedy eye motion. This will likely clarify why varied sleep problems—together with sleep apnea—are related to testosterone deficiency.7
A handful of small research have checked out what occurs to hormone ranges when males skimp on sleep.8 In one among these research, members slept simply 5 hours an evening for eight days, leading to a ten to fifteen % drop in daytime testosterone ranges. 9

A examine of 21,469 males discovered that those that consumed meals according to the Mediterranean food regimen had a decrease threat of creating erectile dysfunction over ten years in comparison with males who didn’t comply with the food regimen.14
“Mediterranean diets are additionally identified to advertise coronary heart well being,” says Dr. Asafu-Adjei.
The Mediterranean food regimen emphasizes fruit, greens, complete grains, nuts and legumes, and wholesome fat from meals like olive oil, eggs, and fatty fish. It de-emphasizes pink and processed meat, sugar-sweetened drinks, and sodium.
Nonetheless, consuming patterns that middle on minimally processed complete meals possible supply the identical advantages.

Early people who have been extra curious about mating than fleeing from sharp-clawed wild animals didn’t often dwell lengthy sufficient to move their genes to the subsequent technology.
Nonetheless, not all short-term stressors dampen testosterone. Some can elevate it quickly, together with examination stress or train.16

As an authorized well being coach, it’s out of your scope of apply to advocate dietary supplements to deal with a situation like hypogonadism.
As well as, the increase somebody may get from a complement pales compared to the six items of recommendation above, or to testosterone remedy.
With that vital caveat out of the best way…
There’s a correlation between low zinc consumption and low testosterone ranges.17 18
Nonetheless, to profit from supplementation, somebody should really be poor within the mineral. Merely topping off somebody’s already enough zinc shops possible received’t result in a testosterone increase, and will even trigger hurt.
Checking for and treating a mineral deficiency requires the experience of somebody educated in medical diet remedy. If you happen to lack this coaching, encourage purchasers 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 originally of this story:
Some evolutionary biologists have certainly theorized that males developed to have increased 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 will 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 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 conventional vary. For these males, a healthcare skilled, thorough analysis, and, if warranted, testosterone remedy may be life-changing.
On the identical time, loads of different males proceed to thrive nicely into (and previous!) center age.
Positive, they might 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. Possibly they’re extra affected person, nurturing, and empathetic, for instance.
“Don’t get me flawed. I’d be very sad with an inappropriate or clinically important 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 assume I’ve an excessive amount of to fret about.”
Dr. Berardi just 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 growing old and see this as a brand new season—or will I combat in opposition to it? I might colour my hair, do hair transplants, prime 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?’”
