Tucker Carlson hosted a personal trainer who said $4 could increasetestosterone levels inmen .- Few human studies have shown a link between red light and testosterone, and the studies that do exist have small sample sizes.

$4, a certified personal trainer at LifeTime Fitness in Columbus, Ohio, appeared on Carlson's show on Sunday to claim exposure to red light therapy can raise testosterone levels in men.
"I was recently exposed to a term called 'bromeopathy' and I think there's a lot of people out there that don't trust the mainstream information," McGovern said.

Earlier in the show, Carlson promoted a trailer for his new documentary $4 which covers what he described as the "total collapse" of testosterone levels in men.
Concerns about potentially decreasing testosterone levels have been around $4 However, some $4 on that
Carlson told his guest he believes testosterone levels are dropping, and supports people trying red light therapy on their testicles. "Why wouldn't open-minded people seek new solutions?" Carlson asked Kid Rock, who appeared on the show after McGovern.
According to one urologist, the answer to that question is: there are many reasons.
Scant research exists showing a relationship between red light and increased testosterone
Some animal studies have found an increase in testosterone after using low-level laser therapy.
Low-level laser therapy using a 670-nm diode laser appeared to increase testosterone in rats, according to a 2013 study performed in Korea and published in $4. This study suggests red light therapy could influence leydig cells found in the testes that release a class of hormones called androgens, which includes tesosterone. However, rat and human hormone levels $4.
Few human studies demonstrate this relationship. A 2013 study in $4 found semen specimen taken from patients with low sperm mobility could improve progressive motility using a low-level 830-nm diode laser, but the results depend on the laser density and post-exposure time.
"You know how many men's
"And almost all the studies that purport to improvement — whether it's light therapy or the multitude of men's products out there — not a single one has any convincing scientific evidence or properly done studies."
The lack of evidence has not stopped the
