What does this TikTok actually claim?
@therhemantherapist tells his 75,000 viewers that how you wake up is "the easiest way to know your testosterone level as a Man." The video doesn't specify what he means by "how you wake up," but given the testosterone context, he's likely referring to morning erections.
This claim suggests you can accurately assess your hormone levels based on a single physical observation. That's a bold statement that needs serious scrutiny.
Is morning wood really a testosterone test?
Morning erections do correlate with testosterone levels, but they're a terrible diagnostic tool. The Massachusetts Male Aging Study (Feldman et al., Journal of Urology, 1994) found that erectile function declines with age and lower testosterone, but the relationship isn't linear or predictable.
Here's the problem: nocturnal penile tumescence (the medical term) depends on multiple factors beyond testosterone. Sleep quality, stress levels, cardiovascular health, and medications all affect morning erections. A study by Hirshkowitz et al. (Sleep Medicine Reviews, 2007) showed that REM sleep patterns alone can influence erectile function regardless of hormone levels.
You can have normal testosterone (300-1000 ng/dL) and still not experience consistent morning erections. Conversely, some men with clinically low testosterone (below 300 ng/dL) still have them occasionally.
What does actual testosterone testing involve?
Real testosterone testing requires blood work, specifically total and free testosterone levels measured between 7-10 AM when levels peak. The Endocrine Society's clinical practice guidelines (Bhasin et al., 2018) recommend two separate morning measurements below 300 ng/dL to diagnose hypogonadism.
The American Urological Association goes further, suggesting that symptoms alone aren't enough. You need both low lab values and clinical symptoms like fatigue, decreased libido, or mood changes. No single physical sign can replace proper laboratory testing.
Home testosterone tests exist, but they're less reliable than professional lab work. Even then, you're looking at numbers, not guessing based on physical observations.
Why this advice misses the mark
@therhemantherapist oversimplifies a complex hormonal system. Testosterone levels fluctuate throughout the day and can be affected by diet, exercise, sleep, and stress. A single morning observation tells you almost nothing about your overall hormonal health.
This kind of DIY diagnosis can lead men to seek unnecessary testosterone replacement therapy. The FDA has warned against testosterone supplementation in men with normal levels, citing cardiovascular risks including increased heart attack and stroke risk (FDA Drug Safety Communication, 2015).
Worse, focusing on morning erections as a health metric can create anxiety in perfectly healthy men who don't experience them consistently.
What should you actually know about testosterone?
If you're concerned about low testosterone, track multiple symptoms over time. These include persistent fatigue, reduced muscle mass, mood changes, and decreased sexual function. Don't rely on a single physical sign.
The real "easiest way" to know your testosterone level is getting tested by a healthcare provider. Quest Diagnostics and LabCorp offer testosterone panels that cost $50-100 without insurance. Many men's health clinics provide comprehensive hormone testing that includes testosterone, thyroid function, and other relevant markers.
Remember that "normal" testosterone ranges are broad (300-1000 ng/dL), and what's normal for you might not be normal for someone else. Age also matters - testosterone naturally declines about 1% per year after age 30.
