What did @pologuerrero.med actually say?
Here is the honest answer: nothing coherent about testosterone. The transcript attributed to this video is garbled nonsense, likely the product of a failed auto-transcription on a Spanish-language video. Phrases like "President Milano Graza of Resident Evil 3" and "the search manager of the photos" are not medical claims. They are machine-generated gibberish.
The caption, however, tells us something real. @pologuerrero.med, a Spanish-language medical creator with over 2 million views on this video, claims that "your habits literally affect your testosterone" and that "excess is not good either." Those are the actual claims we can evaluate, pulled from the caption because the transcript is unusable.
We will not pretend the transcript contains medical information it does not contain. That would be doing you a disservice. Instead, we will fact-check the caption claims and the category context, which is testosterone replacement therapy and hormone optimization.
Does the science back this up?
The caption claim, that lifestyle habits affect testosterone levels, is well-supported. The claim that excess testosterone is harmful is also backed by evidence. Both are accurate at a general level, though the devil is in the detail nobody provided.
On habits: sleep deprivation alone measurably suppresses testosterone. A 2011 study by Leproult and Van Cauter in JAMA found that one week of sleep restriction to five hours per night reduced daytime testosterone levels by 10 to 15 percent in healthy young men. Obesity, chronic stress, alcohol overuse, and sedentary behavior all have documented negative associations with testosterone production, largely through effects on the hypothalamic-pituitary-gonadal axis.
On excess being harmful: supraphysiologic testosterone, meaning levels pushed above the normal reference range through exogenous use, carries real risks. A 2023 meta-analysis by Bhattacharya et al. in the European Heart Journal found dose-dependent associations between high-dose anabolic androgen use and adverse cardiovascular outcomes, including left ventricular hypertrophy and reduced HDL cholesterol. Excess endogenous testosterone is rarer but also clinically relevant in conditions like congenital adrenal hyperplasia.
What did they get wrong (or right)?
We cannot penalize @pologuerrero.med for claims they did not make in any transcript we can actually read. That would be unfair. What we can say is this: the caption is vague in a way that could mislead. "Habits affect testosterone" is true, but without context, viewers may overestimate how much lifestyle change can move the needle clinically.
For men with clinically confirmed hypogonadism, defined as total testosterone consistently below 300 ng/dL with symptoms, lifestyle changes alone rarely normalize levels enough to matter therapeutically. Endocrine Society guidelines from Bhasin et al., 2018, published in the Journal of Clinical Endocrinology and Metabolism, are explicit that TRT is indicated when biochemical deficiency is confirmed, not as an optional lifestyle add-on.
The "excess is not good" framing deserves credit. Too many testosterone-related social media accounts treat higher as always better. It is not. Polycythemia, testicular atrophy, infertility, and mood disruption are real side effects of unsupervised high-dose testosterone use, and a creator flagging this to 2 million viewers is doing something useful.
What should you actually know?
Testosterone is not a simple dial you turn up with the right morning routine. It is regulated by a feedback loop involving the hypothalamus, pituitary gland, and testes. Lifestyle factors can nudge it, but if your levels are clinically low, no amount of cold showers or zinc supplements will substitute for a proper diagnosis and, where warranted, medical treatment.
If you are considering TRT, the process should start with two morning blood draws confirming low total testosterone, plus evaluation of LH, FSH, prolactin, and a full metabolic panel. Self-administering testosterone without this workup risks suppressing your natural production unnecessarily and missing an underlying condition driving the low levels. Pituitary tumors, for example, can present as low testosterone.
Telehealth platforms operating in regulated environments are required to conduct this kind of evaluation before prescribing. If a platform skips it, walk away. And if a TikTok video is your primary source of hormone health information, use it as a starting point for questions to ask a physician, not as a treatment protocol.
