Of the 32 symptoms men commonly attribute to low testosterone — fatigue, brain fog, low mood, weight you can't lose, feeling not quite like yourself — only three actually correlate with low T on the largest prospective study we have. All three are sexual: decreased morning erections, decreased sexual thoughts, and erectile dysfunction.
The other 29 are real, but they're produced by something else: poor sleep, untreated metabolic disease, depression, chronic stress, alcohol, medication side effects. Dr. Jordan Feigenbaum and Dr. Austin Baraki walk through the European Male Aging Study finding and how to actually evaluate a man with a ten-symptom checklist without dismissing what he's experiencing. From Episode 2 of our Signal book launch series.
