Across the United States, testosterone levels in men have been quietly declining for decades. It isn’t just a problem of aging. Younger men today often have significantly lower testosterone than men of the same age in previous generations. Researchers have documented this trend repeatedly, yet the deeper question rarely gets asked.
Are Modern Testosterone Levels Truly Normal?
Or are they simply the statistical average of a metabolically stressed population?
From the perspective of Mother Luck Ranch—and the ancestral nutrition principles taught by the Weston A. Price Foundation—those are two very different things.
When we talk about health here, we’re not talking about what is common. We’re talking about what is biologically robust. The difference matters.
The Modern Medical Definition of “Normal”
Most laboratories in the United States define normal total testosterone roughly between: 300–900 ng/dL. Some labs even set the lower limit closer to 264 ng/dL.
In practice, this means a man with testosterone around 350–450 ng/dL will often be told everything looks fine—even if he is experiencing symptoms like fatigue, reduced drive, slow recovery from exercise, or loss of muscle mass.
This is because modern reference ranges are statistical. They are based on averages from the current population.
If the population itself becomes less healthy, the “normal” range shifts downward with it.
This is exactly what appears to be happening.
The Generational Testosterone Collapse
Several studies have confirmed that testosterone levels have declined significantly over the past few decades.
One study published in the Journal of Clinical Endocrinology & Metabolism tracked American men and found testosterone levels dropped substantially between the 1980s and early 2000s—even after adjusting for age and obesity (Travison et al., 2007).
More recent national survey data suggests the same trend continues today. Average testosterone among U.S. men fell from roughly 605 ng/dL around the year 2000 to about 451 ng/dL by 2015–2016 (Urology Times analysis of NHANES data).
In other words, what was once considered mediocre is now considered normal.
From an ancestral health perspective, that should raise eyebrows.
Because when we step outside modern industrial life and look at traditional cultures—the kind Weston A. Price studied in the 1930s—we see a very different picture of male vitality.
What Weston A. Price Observed
Weston A. Price traveled the world studying populations who still ate their traditional diets and lived close to the land. He did not measure testosterone levels directly. Hormone testing was not available in the field at the time. But he documented physical markers of endocrine health that strongly correlate with robust testosterone levels:
- Broad facial structure
- Dense bone development
- Strong musculature
- High fertility
- Physical stamina
- Resilience to disease
Across cultures—from the Swiss Alps to the Polynesian islands to African pastoral societies—Price consistently observed men with remarkable physical strength and vitality.
These populations were eating diets rich in:
- Pastured animal fats
- Organ meats
- Raw dairy
- Fresh seafood
- Bone broths
- Mineral-rich plants grown in living soil
When these same populations adopted industrial foods—refined flour, sugar, canned goods, and vegetable oils—degeneration appeared within a single generation.
Modern endocrinology now recognizes that the endocrine system is deeply tied to nutrient density and metabolic health. In many ways, Price was observing hormone health long before we had the language to describe it.
What Ancestral Health Practitioners Consider Optimal
Within ancestral health and regenerative agriculture circles—communities deeply influenced by Weston A. Price—the conversation around testosterone looks a little different.
Instead of asking whether someone falls within the statistical range, the question becomes:
Is the body functioning at its natural capacity?
Many practitioners in this space consider the following ranges more reflective of robust hormonal health:
Optimal vitality: 700–900 ng/dL
Strong metabolic health: 600–700 ng/dL
Borderline metabolic stress: 450–600 ng/dL
Low testosterone physiology: below 450 ng/dL
These are not official medical ranges. They reflect patterns observed in men who report high energy, strong recovery, and stable metabolic health.
A man sitting in the mid-400s might still be labeled “normal” in a laboratory report, but many men report feeling noticeably better once levels rise into the 600–700 range.
The Modern Environmental Pressures Lowering Testosterone
To understand why testosterone has declined, we have to zoom out and look at the modern environment.
In regenerative agriculture we talk constantly about soil health. When soil biology is degraded, crops weaken. The human body is not that different. Our internal terrain matters.
Several forces in modern life place constant pressure on the endocrine system.
Metabolic disease
Excess body fat increases the activity of an enzyme called aromatase, which converts testosterone into estrogen. Rising obesity rates directly correlate with declining testosterone levels.
Endocrine-disrupting chemicals
Modern life exposes us to thousands of synthetic chemicals that did not exist in traditional environments.
Compounds like BPA, phthalates, and certain pesticides can interfere with hormone signaling. These chemicals are now commonly found in plastics, food packaging, personal care products, and agricultural systems.
Sleep disruption
Testosterone production peaks during deep sleep. Chronic sleep disruption—especially conditions like sleep apnea—can significantly suppress hormone production.
Sedentary living
Human bodies evolved for movement and physical labor. A lifestyle of prolonged sitting reduces the mechanical stimulus that supports testosterone production.
Ultra-processed diets
Traditional diets emphasized fat-soluble vitamins and mineral density. Modern diets often emphasize refined carbohydrates and industrial seed oils while lacking key nutrients required for hormone production.

Sunlight deprivation
Sunlight supports circadian rhythms, vitamin D production, and mitochondrial function. Reduced outdoor exposure can disrupt multiple hormonal pathways.
When these factors combine, the endocrine system adapts by dialing hormone production down. The body shifts from a state of vitality toward a state of survival.
Sun Gazing: Reclaiming Light as a Nutrient has become a critical part of our daily routine for wellbeing.
A Regenerative Approach to Hormone Health
At Mother Luck Ranch, we approach health through the same lens we apply to land stewardship.
If soil is depleted, you don’t pour synthetic inputs on top and call it solved.
You rebuild the ecosystem.
The human body works the same way.
At Mother Luck Ranch we believe the same principle applies to land and human health. Healthy soil produces resilient crops. Healthy biological terrain produces resilient people.
When testosterone levels decline across an entire population, it is rarely just a hormone problem. It is a systems problem.
Sleep, sunlight, food quality, stress, environmental toxins, and physical activity all send signals to the endocrine system about whether the body should prioritize survival or vitality.
When those signals begin to resemble the rhythms our biology evolved with, the body often begins correcting itself.
Natural Ways to Increase Testosterone
We focus on rebuilding health from the ground up. That means addressing the environmental and biological signals that tell the body whether to operate in survival mode or vitality mode.
Improve sleep quality
Testosterone production occurs primarily during deep sleep. Men with chronic sleep disruption often show dramatically lower testosterone levels.
Sleep apnea is one of the most common hidden causes of low testosterone in otherwise healthy men.
Practical steps:
- Sleep in a completely dark room
- Avoid screens for one hour before bed
- Finish eating three hours before sleep
- Get morning sunlight within 30 minutes of waking
- Aim for 7–9 hours of consistent sleep
Studies have shown that even one week of restricted sleep can significantly lower testosterone levels in healthy men (Leproult & Van Cauter, Journal of the American Medical Association).
Strength Training with Heavy Resistance
The human body evolved under conditions of physical labor and resistance.
Heavy compound movements stimulate testosterone production far more effectively than steady-state cardio.
Recommended approach:
- Strength train 3–4 days per week
- Focus on large compound movements
- Squats
- Deadlifts
- Push movements
- Pull movements
Even short sessions of intense resistance training can stimulate testosterone release.
Sunlight and Vitamin D
Vitamin D acts more like a hormone than a vitamin. Low vitamin D levels are strongly associated with lower testosterone.
One randomized trial found vitamin D supplementation increased testosterone levels in deficient men over a one-year period (Pilz et al., Hormone and Metabolic Research).
Natural approaches:
- 20–30 minutes of midday sunlight exposure when possible
- Daily outdoor time
- Maintaining vitamin D levels between roughly 40–60 ng/mL
- Add a daily fermented cod liver oil supplement. Bonus if it also contains concentrated butter oil to improve bioavailability. We use this one from Green Pasture.
Eat Nutrient-Dense Animal Foods
Testosterone production depends on cholesterol and fat-soluble nutrients. Traditional diets emphasized foods rich in these building blocks.
Foods that support hormone production include:
- Pastured red meat
- Egg yolks
- Liver and organ meats
- Shellfish such as oysters
- Raw or grass-fed dairy
- Bone broth
- Tallow and butter
Zinc, vitamin A, cholesterol, and fat-soluble vitamins all play roles in hormone synthesis.
Reduce Chronic Stress
Cortisol and testosterone operate like opposite sides of a seesaw. When cortisol remains elevated for long periods, testosterone production declines.
Supportive practices include:
- Daily outdoor time
- Slow breathing practices
- Regular physical activity
- Time away from screens and constant stimulation
Even simple routines such as evening walks can help shift the nervous system away from chronic stress signaling.
Reduce Endocrine Disruptor Exposure
Modern life exposes the body to chemicals that can interfere with hormone signaling.
Reducing exposure can include:
- Avoiding plastic food containers
- Using glass or stainless steel instead
- Filtering drinking water
- Choosing natural personal care products
- Limiting pesticide exposure
Many endocrine disruptors mimic estrogen inside the body, which can further suppress testosterone.
Maintain Metabolic Health
Insulin resistance and visceral fat are strongly associated with lower testosterone.
Practical metabolic support includes:
- Prioritizing protein at each meal
- Reducing ultra-processed foods
- Maintaining stable blood sugar
- Incorporating daily movement
Even moderate fat loss in overweight men has been shown to increase testosterone levels.
Average Is Not the Same as Healthy
One of the most important lessons from both regenerative agriculture and ancestral nutrition is this:
What is common is not always what is natural.
The goal is not simply to fall within a laboratory reference range. The goal is to restore the conditions that allow the body to thrive.
Modern testosterone ranges reflect the metabolic reality of a population living with chronic stress, disrupted circadian rhythms, chemical exposure, and nutrient-poor diets.
When we measure against that baseline, the bar for “normal” becomes surprisingly low.
But when we look at traditional cultures—those living closer to the rhythms of land, animals, and sunlight—we see a different picture of human vitality.
That perspective is worth remembering.
Because sometimes the goal isn’t simply to fall inside the laboratory range.
Sometimes the goal is to restore the conditions that allow the body to thrive the way it was designed to.
And in many ways, that journey looks remarkably similar to what we are doing on the land here at Mother Luck Ranch: rebuilding health from the soil up.
