Men across America are being told their testosterone is “fine” when they feel anything but.
Others are handed prescriptions for testosterone replacement therapy without anyone asking the most critical question: why is your testosterone low in the first place?
According to Dr. Seth, an ER physician and former special operations member, two broken systems are mishandling the testosterone conversation—and most men are paying the price with their health.
In a recent video breaking down the testosterone crisis, he reveals what doctors aren’t asking and why the answer to low testosterone usually has nothing to do with a prescription.

Two Systems, Same Problem
Dr. Seth identifies two distinct but equally flawed approaches currently dominating men’s health.
Traditional medicine operates on a simple but inadequate protocol. A man presents with fatigue, low libido, muscle loss, brain fog, and weight gain. If he’s lucky, his doctor orders a testosterone test. Total testosterone comes back at 320 nanograms per deciliter—technically within the “normal” range of 300 to 1,000.
Conversation over. Patient dismissed.
Doctor says you’re fine. Well, you are not fine. You feel terrible, but the number says normal, so the conversation is somehow over.
In other cases, doctors prescribe testosterone gel without investigating sleep quality, diet, stress levels, body composition, or exercise habits. The gel itself presents problems—inconsistent absorption, risk of transfer to partners and children through skin contact, and immediate suppression of natural testosterone production.
The second system involves online TRT clinics that have proliferated rapidly. While some maintain legitimate medical standards, many others follow a troubling pattern: prescribe testosterone to virtually anyone who requests it, regardless of actual levels or underlying causes.
The Question Nobody’s Asking
What’s causing your low testosterone?
Dr. Seth emphasizes this is where both systems fail catastrophically. For most men experiencing low testosterone, the testicles haven’t simply “stopped working.” Instead, lifestyle factors are systematically destroying hormonal health—factors that are entirely reversible without pharmaceutical intervention.
The Tests You Actually Need
Most men who’ve had testosterone checked received incomplete, misleading information. Dr. Seth recommends a comprehensive panel that reveals the full hormonal picture:
- Total testosterone – Only a starting point, tells you bound and unbound testosterone combined
- Free testosterone – The biologically active form that actually correlates with symptoms
- Sex hormone binding globulin (SHBG) – The protein that binds testosterone, making it unavailable; influenced by sleep, body fat, diet, and training
- Estradiol – Elevated estrogen produces symptoms identical to low testosterone when fat tissue converts testosterone to estrogen
- FSH and LH – Reveals whether the problem originates in the brain (low signals) or testicles (adequate signals, poor response)
- Morning cortisol – Chronically elevated cortisol directly suppresses testosterone production
- TSH, Free T3, Free T4 – Hypothyroidism mimics low testosterone symptoms almost perfectly
Without this complete picture, men risk treating the wrong problem entirely.
Three Non-Negotiable Levers
Before considering testosterone replacement, Dr. Seth prescribes six months of focused lifestyle intervention. Most men won’t follow through, he admits candidly, because everyone wants the quick fix.
If you are not willing to put in the work now, you’re probably not going to put in the work after you go on testosterone, and it’s going to do absolutely nothing for you.
Lever One: Sleep
A landmark study published in JAMA found that healthy young men sleeping less than five hours nightly for just one week experienced testosterone levels 10-15% lower than when fully rested. That single week of poor sleep aged their hormonal profile by 10-15 years.
Testosterone production occurs primarily during deep sleep, pulsing throughout the night and peaking in early morning hours. Cut sleep short, and you slash that production window. Quality matters as much as quantity—undiagnosed sleep apnea fragments sleep architecture and tanks testosterone even when spending eight hours in bed.
The prescription: Seven to nine hours, consistent schedule, dark cool quiet room. Non-negotiable.
Lever Two: Lifting Heavy
Compound movements—squats, deadlifts, rows, presses—produce significant acute hormone responses. Testosterone spikes 15-30 minutes post-workout, and consistent training creates a more favorable overall hormone environment with reduced body fat, improved insulin sensitivity, lower cortisol, and higher growth hormone.
Critically, resistance training reduces visceral fat, which directly decreases aromatase activity. Aromatase converts testosterone to estrogen, so less body fat means more testosterone remains testosterone.
Research demonstrates that exercise training alone improves arterial function by 28%, while TRT without exercise shows zero improvement. Cardiovascular health responds to physical effort in ways hormones cannot replicate.
The prescription: Three days weekly, compound movements, six months minimum.
Lever Three: Nutrition
Two evidence-based priorities dominate nutritional strategy for testosterone optimization.
First, eat enough. Chronic caloric restriction, especially severe fat restriction, suppresses testosterone production. Testosterone synthesis requires cholesterol—your body needs dietary fat. Men chronically restricting calories or eating very low-fat consistently show depressed testosterone levels.
The body interprets severe caloric deficit as famine. During perceived famine, reproduction becomes non-priority. Testosterone drops accordingly.
Second, minimize ultra-processed foods. Processed food drives insulin resistance, which disrupts the hypothalamic-pituitary-gonadal axis regulating testosterone production. It also promotes fat accumulation, increasing aromatase activity and converting more testosterone to estrogen.
The prescription: Real food, adequate calories, prioritize protein and natural fats, consistently.
The Stress Factor
Cortisol and testosterone exist on opposite ends of a hormonal seesaw. Chronically elevated cortisol from work stress, relationship problems, overtraining, sleep deprivation, or under-eating suppresses testosterone production directly at the hypothalamic level.
You cannot out supplement or out medicate a chronically stressed nervous system. If you are running on cortisol all day, every day, your testosterone will reflect that.
No amount of TRT fixes underlying chronic stress. You simply become the stressed guy on testosterone, creating an entirely new set of complications.
When TRT Is Actually Appropriate
Dr. Seth emphasizes he’s not anti-TRT. Testosterone replacement serves legitimate medical purposes for specific populations.
Men with primary hypogonadism—where testicles fail to produce testosterone due to injury, illness, or genetic condition—genuinely benefit from replacement therapy. Men who’ve optimized lifestyle factors for at least six months whose levels remain clinically low with no correctable underlying cause also represent appropriate candidates.
For these men, working with responsible clinics that examine comprehensive lab panels rather than isolated total testosterone can prove life-changing.
But that’s not most men currently starting TRT. Most are sleep-deprived, overtrained, underfed, chronically stressed, carrying excess body fat, and consuming processed foods multiple times daily. None of these underlying issues have been addressed before the prescription gets written.
The Six-Month Protocol
Dr. Seth outlines a clear path forward that prioritizes biology over pharmacology.
First, obtain comprehensive labs—total testosterone, free testosterone, SHBG, estradiol, FSH, LH, morning cortisol, and complete thyroid panel. Establish baseline data showing exactly what’s happening hormonally.
Then commit to six months: sleep seven to nine hours nightly, lift three days weekly with compound movements, eat real food in adequate quantities, and actively manage stress and training load.
Retest after six months. If levels remain low with FSH and LH indicating genuine production problems despite optimized lifestyle factors, then have an informed conversation with a responsible men’s health clinic.
But approach from knowledge and data, not desperation.
Based on clinical experience with hundreds of men, Dr. Seth predicts most won’t need that conversation—because most have never actually provided their bodies the conditions required for optimal testosterone production.
Give your biology those conditions first. The prescription pad can wait.
