Hormone Optimization — South Dakota & Colorado

You're 25 and exhausted.
Your labs came back “normal.” — They're not. Let's find out why.

Low testosterone in young men is real, measurable, and treatable — without a lifetime on TRT. Dr. Walters holds a PhD in reproductive endocrinology and finds the cause, not just the number.

Why this practice is different

Most clinics hand younger men testosterone — and a lifetime of dependency. We restore your own production instead.

Fertility intact. Your body's machinery back online. That's the difference between renting a fix and owning one.

The research that changed everything

Dr. Walters earned his PhD in reproductive endocrinology with a focus on ovarian oxytocin. At the time, oxytocin was classified exclusively as a brain peptide produced by the hypothalamus. His post-doctoral research demonstrated that the ovary also produces oxytocin — a finding that contradicted established medical teaching and contributed to a fundamental reclassification of the hormone. That early experience — following the evidence against institutional consensus — has defined everything since.

From research to the bedside

A drive to help people — not just study them — led Dr. Walters to leave academic research and earn an MBA. He took over management of a small rural hospital on the brink of financial failure and restored it to profitability within four years. So moved by the direct impact a single physician could have on a rural community, he enrolled in medical school at 40 years old.

He and his wife, along with their 10 children, relocated to Des Moines, Iowa, where Dr. Walters completed his medical degree (DO) and a Family Practice residency. The family then moved to southern Colorado, where his clinical career began.

25 years of hormonal medicine

Over the course of his career, Dr. Walters' practice has evolved into a specialty clinic focused entirely on the restoration and optimization of hormones in male and female patients of all ages. His central focus is understanding why hormones become dysregulated in the first place — not simply replacing what has been lost.

His research and clinical experience converge on a clear answer: the population-level decline in testosterone he has observed over 25 years is being driven, in significant part, by ubiquitous exposure to endocrine-disrupting chemicals (EDCs) that suppress the hypothalamic-pituitary-gonadal (HPG) axis. This is not a fringe hypothesis. It is supported by decades of peer-reviewed research.

Fitness as medicine

Dr. Walters has used exercise as a clinical tool throughout his career. Fifteen years ago he discovered CrossFit and was so impressed by the results that he built his own CrossFit gym. He competed in the CrossFit Games in 2014 and 2016 in the 60+ age division. One of his patients who joined his gym in 2011 went on to win the 2015 CrossFit Games in the 60+ female division. He holds himself to the same standard he asks of his patients.

Young Men & Low Testosterone

You're 25 years old. Your testosterone is low. And your doctor told you you're fine.

You're not fine. And you're not alone. Low testosterone in young men is not rare, not mysterious, and not untreatable. But it requires a physician who actually understands why it's happening — and most don't.

Book a consultationRead the research →

You are not imagining this

If you are in your 20s or 30s and experiencing any of the symptoms listed here, your HPG axis is almost certainly being suppressed. The question is not whether it's happening — it's what's causing it.

These symptoms are real. They are measurable. And the medical profession is failing young men by either dismissing them or responding with testosterone replacement — which is wrong for most young men.

Symptoms
→Fatigue that sleep doesn't fix
→Difficulty building muscle despite consistent training
→Accumulating body fat, especially around the abdomen
→Low sex drive or erectile dysfunction
→Brain fog, difficulty concentrating, or memory problems
→Mood swings, irritability, anxiety, or depression
→Poor recovery from exercise
→Feeling like a 50-year-old in a 25-year-old body

Why is this happening?

Multiple large studies document a decline of more than 1% per year in average testosterone levels since the 1980s. Sperm counts in Western men have fallen by more than 50% over the same period.

This is not aging. This is not genetics. This is chemistry.

The scientific evidence points strongly to endocrine-disrupting chemicals (EDCs) — synthetic compounds found in plastics, food packaging, pesticides, tap water, and personal care products — that mimic estrogen and bind to receptors in the hypothalamus and pituitary. Your body is not broken. It is being chemically suppressed.

Treatment

Why testosterone replacement is the wrong answer for most young men

Testosterone Replacement (TRT)
✕Signals the pituitary to stop producing LH and FSH
✕Your testes shrink from disuse
✕Natural testosterone production ceases
✕Sperm count drops to zero — functional infertility
✕Many men become permanently dependent
Clomiphene Citrate
✓Targets the mechanism of suppression, not the symptom
✓Your testes continue to function normally
✓Your own testosterone rises to optimal levels
✓Fertility is preserved
✓No external hormones — no permanent dependency

Natural Hormone Optimization

Your hormones didn't fail you.
They were disrupted.

The modern environment is saturated with synthetic chemicals that interfere directly with your body's hormone production. Most physicians never test for this. Dr. Walters has spent 25 years building the clinical framework that connects the published evidence to the patient in front of him — and it explains what most physicians cannot.

For Men For Women Young Men Specifically →

What is causing your hormone imbalance?

Human hormone levels are in measurable, documented decline — and have been for decades. Testosterone levels in men have fallen by more than 1% per year since the 1980s. Sperm counts in Western men have dropped by more than 50% over the same period. This is happening to young men in their 20s and women in their 30s showing hormonal profiles associated with menopause.

The leading scientific explanation is ubiquitous exposure to endocrine-disrupting chemicals (EDCs): synthetic compounds that interfere with the body's endocrine system at the receptor level.

01They mimic naturally occurring hormones — particularly estrogens — triggering responses the body did not intend
02They bind to hormone receptors and block the body's own hormones from activating them
03They suppress the normal production of testosterone by disrupting the hypothalamic-pituitary-gonadal (HPG) axis
For Men

Symptoms of EDC-related hormonal disruption

These symptoms used to appear primarily in men over 50. Today, Dr. Walters sees them routinely in men in their 20s and 30s:

→Persistent fatigue and low energy
→Low sex drive or erectile dysfunction
→Inability to build or maintain muscle
→Increased body fat, particularly abdominal
→Brain fog, poor concentration, memory problems
→Mood swings, irritability, or depression
→Poor sleep quality, low sperm count, bone density loss
For Women

Symptoms of EDC-related hormonal disruption

EDCs reduce testosterone in women as well as men. Symptoms that once appeared only at menopause are increasingly common in women in their 30s:

→Fatigue and persistent low energy
→Low libido
→Loss of muscle mass and increased body fat
→Brain fog and poor concentration
→Depression or mood instability
→Sleep disruption
→Infertility, osteopenia, or osteoporosis

Dr. Walters' approach: treating the cause, not the number

Most hormone clinics measure a testosterone level and prescribe testosterone. Dr. Walters considers this approach incomplete — and for young patients, potentially harmful. His evaluation includes:

→Complete hormonal panel: testosterone (total and free), LH, FSH, estradiol, SHBG, DHEA, thyroid, cortisol, and more
→Assessment of HPG axis function — where in the system is the disruption occurring?
→Detailed history of chemical exposures, lifestyle, and environmental contributors
→Evaluation of nutritional status, including Vitamin D, which regulates multiple hormonal pathways

Real patients. Real results.
Real words.

Unedited, unsolicited accounts from patients who were dismissed, mismanaged, or failed by mainstream medicine — and found a physician who actually figured out what was wrong.

"

Dr. Walters found all the reasons why I felt the way I did — hypogonadism, low testosterone, low vitamin D. He prescribed the right treatment and I felt better than I had felt in years.

When I first came to Dr. Walters, I had been dismissed by multiple physicians who told me my labs were "normal." I was exhausted, couldn't build muscle despite training consistently, and felt like a shell of myself at 27. Dr. Walters was the first physician who actually dug into why my testosterone was low. He identified hypogonadism, low testosterone, and low Vitamin D as connected pieces of the same puzzle. Within a few weeks I felt better than I had felt in years.

Doc Walters is more than my physician. He is one of my most trusted mentors. I have never had a doctor care as much or invest as much in me as he has over these last six years.

I came to Dr. Walters after years of feeling like my body was working against me despite everything I had done in my career to stay physically elite. What I found was a physician who actually wanted to understand the root cause — not just manage symptoms. Over six years, he has transformed how I think about health, performance, and aging. Doc Walters is more than my physician. He is one of my most trusted mentors.

At 45 years old, I feel like and I'm performing as if I am back in my late 20s. I could never quantify how much my quality of life has improved.

Before working with Dr. Walters, I had accepted that how I felt was just what getting older looked like. I was wrong. At 45 years old, I feel like I'm performing as if I'm back in my late 20s. The lab tests confirm it — objective markers of health have improved significantly. But numbers don't capture what this has actually meant for my daily life and my sense of self. Dr. Walters gave me that.

Dr. Walters has unequivocally helped me with every condition I came to him with. He does not treat the symptom — he treats the root cause.

I have been a patient of Dr. Walters for over twelve years. In that time, he has helped me with osteoporosis, extreme depression, insomnia, postmenopausal symptoms, and so much more. He sits with you, listens deeply, and actually figures out why your body is struggling. He gives you hope and the tools for self-empowering control over your own health.

Most hormone clinics measure a testosterone number and prescribe testosterone. Dr. Walters evaluates the entire HPG axis to understand why your hormones are dysregulated. He holds a PhD in reproductive endocrinology — a credential virtually no other hormone clinic physician holds — and has 25 years of clinical experience treating the root cause of hormonal decline. His central clinical insight — that EDC exposure drives HPG axis suppression via ERα agonism at the hypothalamus, and that clomiphene citrate is the mechanistically targeted response — is a synthesis no other practicing physician has published.
Yes. Dr. Walters treats male and female patients of all ages. His practice includes hormone optimization for menopause, andropause, low testosterone in young men, and complex hormonal presentations across the lifespan.
Dr. Walters is based in South Dakota and holds a monthly two-day clinic in Colorado Springs, Colorado. South Dakota patients are seen via telemedicine or in person in his Hot Springs, SD clinic. Colorado patients are seen in person for their first visit, then via telemedicine.
Yes. South Dakota patients can book a telemedicine appointment by calling (719) 544-0199. Colorado patients are seen at the monthly Colorado Springs clinic. Contact Jenny Thompson, Office Manager, to schedule.
For Young Men
Yes — and this is one of Dr. Walters' primary areas of focus. Low testosterone in young men is increasingly common and is often driven by endocrine-disrupting chemical (EDC) exposure that suppresses the HPG axis. For most young men, Dr. Walters uses clomiphene citrate rather than testosterone replacement — an approach that restores natural production without suppressing fertility or creating long-term dependency.
Exogenous testosterone signals your body to stop producing its own. For a young man, this typically results in testicular atrophy, reduced sperm production, and potential permanent fertility consequences. Clomiphene addresses the mechanism of suppression rather than bypassing it. It is a fundamentally more appropriate treatment for most young men.
Dr. Walters is a cash-pay practice and does not bill insurance. Lab work is ordered through major laboratories that bill insurance directly for insured patients.
Telemedicine
Yes. South Dakota patients can establish a complete physician-patient relationship via secure video telemedicine — no in-person visit required. Colorado patients require one in-person visit to the Colorado Springs clinic, after which all follow-up care can be via telemedicine.
Any device with a camera and microphone — smartphone, tablet, or computer. Dr. Walters uses the free Spruce Health app for secure, HIPAA-compliant calls and video appointments. Download Spruce, then call the office at (719) 544-0199 through the app at your appointment time.
Yes. Labs are ordered through major national laboratories. You have your blood drawn at a local lab near you and the results are sent to Dr. Walters for review.

The Chemically Castrated Generation

How endocrine disruptors are suppressing young men's testosterone — and the $2 pill that restores it.

From the Author

For fifteen years I have watched young men walk into my clinic exhausted, flat, and quietly certain that something was wrong with them. Most had already been told they were fine. Most had been handed an antidepressant. Almost none had ever had their testosterone checked.

When I checked it, the number was often lower than their grandfather's.

This book is the case I have spent a career assembling — and it is a clinical case, start to finish. The decline is real. The cause is chemical. And the treatment costs about two dollars a dose.

What the book argues

Testosterone in young American men has fallen by nearly half in four decades. Sperm counts have dropped by more than half. The chemicals driving the decline — the bisphenols, phthalates, and organochlorines that entered the food and water supply at industrial scale beginning in the 1970s — suppress the hormonal signal at the level of the brain, not the testes.

The result is a clinical picture — fatigue, low drive, depression that does not lift with antidepressants — that is being read as primary mental illness, because the framework that would identify the hormonal cause is not taught in most medical schools.

The standard answer, testosterone replacement, makes the underlying problem worse: it suppresses an already-fragile system further. The better answer is a generic medication that has been on pharmacy shelves for half a century, costs about two dollars a dose, and restores a man's own production rather than replacing it. It is called clomiphene citrate — and it may be the most important men's health medication most physicians have never prescribed for this purpose.

This book documents the crisis, names the mechanism, and lays out the treatment.

These young men did not lose their testosterone. In most cases, they never had it in the first place.
Who it's for

Written for three readers

The Young Man

Whose labs were called “normal”

Told for years that the way he feels is in his head — when a single blood test, read against the right baseline, would have told a different story.

The Parent

Watching a son disappear

Into fatigue, lost motivation, and a stack of prescriptions that aren't working — and unable to get a straight answer about why.

The Physician

Who suspects something is missed

And wants the evidence base intact and the clinical reasoning visible — the mechanism, the studies, and the protocol, not a polemic.

Built on 140 peer-reviewed studies — including the work of Swan, Levine, Skakkebæk, Travison, and Lokeshwar — and written so all three can follow it without being talked down to.

David Walters, DO, PhD, MBA

David Walters has spent twenty-five years restoring hormonal function in men and women. He began his scientific career in reproductive endocrinology — his research demonstrated that the ovary produces oxytocin, a finding that contradicted the medical teaching of the time — and entered medical school at forty, after turning around a failing rural hospital as its administrator. He writes the Medical Anarchy Substack and practices in South Dakota and Colorado.
