Are EDCs silently suppressing your testosterone?
You're in your 20s or 30s, exhausted, struggling to build muscle, and your drive has disappeared — but your doctor told you everything is "normal." It isn't. Dr. Walters is one of the few physicians who can identify the cause and treat it without putting you on testosterone for life.
Learn why →You're exhausted, gaining weight, losing drive — and your doctor says your labs are "within range." They are not looking at the right labs, and they are not asking why. Dr. Walters evaluates the full HPG axis, identifies the environmental and endocrine cause, and builds a treatment protocol targeted at the mechanism — not the symptom.
See how we can help →Most hormone clinics measure a number and replace it. Dr. Walters evaluates HPG axis function to determine where disruption is occurring and why. His clinical framework — EDC-induced ERα agonism driving hypothalamic GnRH suppression — is built on peer-reviewed literature and 25 years of clinical observation. He welcomes referrals and collegial consultation.
Referral information →One phone call to Jenny. She'll get you on the calendar — telemedicine for South Dakota (no in-person visit required) or monthly in-person clinic in Colorado Springs. Most patients are seen within two weeks.
Dr. Walters takes a complete health and exposure history, orders a comprehensive hormone panel, and assesses your full HPG axis — not just a single testosterone number.
You receive a cause-targeted treatment protocol — not a testosterone prescription. Most patients report measurable improvement in energy, drive, and body composition within 3–4 weeks. Follow-up labs confirm what they're feeling.
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.
Dr. Walters has helped me with osteoporosis, extreme depression, insomnia, postmenopausal issues, and so much more. He does not treat the symptom — he treats the root cause.
I have never had a doctor care as much or invest as much in me. Doc Walters is constantly researching and finding new ways to live a healthier, stronger life.

Read on Substack →One of the only physicians in the United States with a PhD in reproductive endocrinology and 25 years of clinical experience in hormonal optimization — for men and women of all ages.
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.
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.
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.
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.
Dr. Walters sees patients in South Dakota via telemedicine and in person and in Colorado at monthly in-person clinic visits. He personally uses and believes in every protocol he prescribes.
Jenny manages the day-to-day administration of the clinic with precision and warmth. She handles scheduling, patient inquiries, and the operational infrastructure that allows Dr. Walters to focus entirely on patient care.
Karlie serves as the clinical backbone of every in-person patient visit. Her energy, warmth, and clinical skill ensure every patient feels heard and well cared for. She has been a cornerstone of Dr. Walters' practice for over 11 years.
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.
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.
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.

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.
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.
These symptoms used to appear primarily in men over 50. Today, Dr. Walters sees them routinely in men in their 20s and 30s:
EDCs reduce testosterone in women as well as men. Symptoms that once appeared only at menopause are increasingly common in women in their 30s:
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:

Dr. Walters evaluates the full HPG axis and uses targeted interventions — primarily clomiphene citrate for men with EDC-driven suppression — that restore endogenous production without creating dependency.
