Fox News host Tucker Carlson can’t cease speaking about balls. He’s deeply involved about an alleged “crash” in testosterone ranges amongst American males, a lot in order that he produced a whole documentary about it known as The End of Men. The trailer, which dropped on Friday, reveals a bunch of ripped, shirtless dudes doing man stuff: capturing weapons, wrestling one another, chopping down bushes, milking cows (???), and chugging uncooked eggs. Perhaps most notably, it additionally features a shot of a totally bare man blasting his genitals with a purple mild remedy machine.

Carlson has grow to be an enormous proponent of so-called “testicle tanning”: exposing one’s nuts to infrared mild in an effort to spice up testosterone. He endorsed the follow throughout a section of The End of Men with self-described “fitness professional” Andrew McGovern, who claimed that testicle tanning and purple mild remedy have “a massive amount of benefits.” Later on within the doc, Carlson pitched the concept to Kid Rock, for some cause, imploring him to “open [his] mind.”

“Don’t you think at this point, when so many of the therapies, the paths they’ve told us to take, have turned out to be dead ends that have really hurt people, why wouldn’t open-minded people seek new solutions?” Carlson requested. A seemingly baffled Kid Rock simply shook his head and stated, “I don’t know what the hell is going on in this world.”

There isn’t a lot analysis demonstrating that purple mild remedy has therapeutic advantages. The Cleveland Clinic notes that “the full effectiveness of red light therapy has yet to be determined.” We know even much less about testicle tanning, particularly.

To get a greater sense of what may occur once you zap your testicles with an infrared mild machine, VICE known as up Seth Cohen, a urologist and the director of the Sexual Dysfunction Program at NYU Langone Health. He weighed in on the alleged advantages of testicle tanning (spoiler: there most likely aren’t any), and what may go incorrect for individuals who attempt it (one other spoiler: most likely loads).

VICE: As far as , does testicle tanning truly enhance testosterone?

Seth Cohen: Based on literature, based mostly on our data of how the testicles produce sperm and testosterone, there’s nothing that might lead us to consider that any type of exterior mild or phototherapy would elevate testosterone ranges. I’m not conscious of any science, or information, or any journal publications proving that purple mild remedy improves male testosterone. 

You must additionally understand that there are particular articles which are printed [based on] “anecdotal data.” That principally signifies that one physician noticed this in his follow with 10 or 20 sufferers. That’s not one thing we’re going to change our suggestions on. We change suggestions on medical therapies based mostly on double-blind, placebo-controlled, randomized trials—giant research with 1000’s of sufferers. That’s the place you’ll discover if there’s actually a statistically vital distinction between purple mild remedy and a placebo. Could these males who underwent purple mild remedy and got here out and felt stronger and extra “manly”—may which were a placebo impact? Of course it may.

Is testicle tanning probably harmful? If so, what are the dangers?

From what I’ve learn, it looks as if that is used predominantly for wound care and skincare, which might make sense, since you’re shining this in your pores and skin. But pondering that that is going to go deeper by way of the pores and skin, by way of a number of layers, after which into testicles—I can’t see that working or occurring. And, if it does, warmth is dangerous to the testicles. Prolonged warmth can truly injury testicle tissue, decrease sperm rely, and be dangerous for fertility. When we’re counseling our male sufferers on what to keep away from by way of fertility preservation or household planning, we inform them to remain out of saunas, scorching tubs, or any extended scorching atmosphere. I would come with testicle tanning in that.

If [testicle tanning] is producing not solely a purple mild beam on the scrotum but in addition producing warmth, I don’t suppose that’s a good suggestion. Especially for fertility planning and fertility preservation. And then extrapolating how that might enhance testosterone—I simply don’t know. It doesn’t make any sense to me. There’s no physiological course of whereby heating up the testicles produces extra testosterone, to my data.

I don’t know if purple mild has the identical injury to pores and skin as, say, daylight or UV mild, which may trigger melanoma and several types of pores and skin cancers. But if it will probably, then I’d positively suggest towards it. Why would you wish to threat getting some kind of pores and skin abrasion or pores and skin most cancers in your scrotum? It can occur. People have gotten pores and skin most cancers on their scrotums. People have gotten pores and skin cancers on their penis. Even although we consider them as protected against the daylight, it positively can occur. So I definitely wouldn’t suggest it, except I noticed a peer-reviewed trial that confirmed that it was one hundred pc protected, with little or no to no threat of pores and skin injury.

What different considerations do you might have in regards to the concept of oldsters exposing their genitals to purple mild remedy? 

I’ve to think about there are several types of purple lights. There are most likely actual purple mild remedy machines, and there are most likely pretend bulbs which are simply projecting purple as a shade. It’s “buyer beware.” I’m positive the primary firm on the market to develop this, that machine perhaps value $1,000, and you’ll solely get entry to it in a dermatology workplace. But perhaps there are knockoffs on-line that you possibly can purchase for a pair hundred bucks, and who is aware of what that machine is doing to you? 

Is testicle tanning one thing that any certified urologist would truly suggest to a affected person?

If you go to any main tutorial middle that has urologists who, I’d hope, follow in a really moral method, I doubt you’ll get anyone who’s going to prescribe purple mild remedy to spice up testosterone. I’ve by no means prescribed it to my sufferers, nor would I see myself doing it anytime sooner or later, till I noticed some information behind it. If sufferers are questioning whether or not that is good for them, they should communicate to their physician, communicate to their urologist, and get an opinion on that. Get an opinion out of your doctor earlier than you expose your physique to continual warmth.

What are some confirmed, science-backed strategies that folks can use to spice up testosterone?

This is one thing that males have been making an attempt to do endlessly to really feel youthful, to have a stronger libido and perhaps a greater intercourse life. The solely approach we all know to try this “naturally,” or by your self with out medical remedy, is with train, eating regimen, and lowering sure behaviors that aren’t wholesome for the physique, like smoking in extra, or ingesting in extra, or medication. For overweight sufferers, weight reduction has been proven to enhance testosterone ranges. Sleep is a vital, but missed and underrated approach of bettering pure testosterone ranges. When folks burn the candle at each ends, or they’re stressed, or they’ve a number of jobs, or they’re partying too onerous at evening, they marvel why they’re not performing very effectively. There are a number of issues we’re doing on our personal, to ourselves, which are negatively impacting our hormones, and naturally our different features. 

There are a subset of males who have been born with or develop low ranges of testosterone. For these males, they could attempt a number of these items—eating regimen and train and sleep—they usually nonetheless really feel sluggish, they usually nonetheless have sexual points. Those males have to come back in to their urologist or their main physician and search remedy. But for essentially the most half, normally, if somebody is making an attempt to spice up pure ranges of testosterone with out having to go towards chemical and medical therapies, eating regimen, train, weight reduction, and sleep are the keys to that success. 

What do you consider Carlson’s concern that testosterone ranges are allegedly dropping amongst American males? Is that one thing that’s truly backed by analysis, and is that one thing to be anxious about, in your view?

I don’t suppose there’s a number of information to indicate dropping testosterone ranges, nationwide or worldwide. There was an article that confirmed a slight lower in fertility charges worldwide and sperm counts worldwide. But there have been just one or two articles; there’s not a number of information there to again that declare up. Am I anxious about it? No. Do sufferers ask me about it loads? Yes. But should you’re main a reasonably wholesome life, your fertility shouldn’t be affected very a lot simply due to these stated traits on the planet.

If a affected person of yours got here in and stated, “Hey, I heard about this testicle tanning thing, and I want to try it,” what would you inform them?

I’d inform them that there’s not a number of information, no less than that I do know of, behind it. If they’ve the information or discovered the information, I’m glad to go over it and browse it. But as soon as once more, purchaser beware. I inform sufferers to deal with their physique and their sexual organs like a temple. When you’re younger and also you’re making an attempt several types of issues, a few of them can have lasting results. You wish to have your fertility and your virility for all times, and never fiddle with issues that probably may damage you now and damage you down the street.
