One conversation. One change. Testosterone marker improved by 33% in four weeks

No new supplements.
No training overhaul.
No dietary intervention.
I told him to stop carrying his phone in his front pocket.
That was it.
He'd been doing it every day for years. Phone against his body for eight, ten, sometimes twelve hours straight. When we remeasured four weeks later — same site, same protocol, nothing else touched — the number had moved more than it had in two years.
Here's what most men haven't been told.
Leydig cells, located in the interstitial tissue of the testes are the cells responsible for producing testosterone — they are sensitive to heat and electromagnetic radiation. Your phone creates a chronic low-level environment those cells don't recover well from.
Multiple peer-reviewed systematic reviews have documented this. What's missing isn't the research. It's someone applying it.
The men I work with are doing everything right. Training. Sleeping. Eating well. Taking the right supplements. And still wondering why the numbers aren't moving.
Sometimes the variable they haven't considered is the one they haven't been asked about.
Where's your phone right now?
