I'm not sure who decided Tucker Carlson is the person to listen to when you want to find out how to become more manly, but the guy has recently teased an upcoming documentary on the subject with clips that include the concept.

I come across things that people talk about on fitness or biohacking forums that are ripe for debunking, but the idea isn't yet mainstream enough for Lifehacker to cover. Sunning your balls or exposing them to a $1,649 panel of red lights is the latest hack that I don't have to write about.

Is there a lot of benefits from exposing your ballsack to red light? There are a lot of benefits that people claim, but the actual science hasn't been able to back them up. The companies that sell the lights and the biohackers who sing its praises tend to cite a few studies that were done in animals or in test tubes, but that aren't specific to testosterone, or the testicles or scrotum.

How is testicular tanning supposed to benefit you? One hypothesis is that red light helps Leydig cells in the testicles to produce more testosterone. Some studies have shown that men with low testosterone and low levels of vitamins D and D are more likely to have low testosterone and low levels of vitamins D and D.

There are problems with these ideas. It's obvious that vitamin D isn't produced in scrotal skin. You can either increase yours by sunning any body part you choose, or by eating more food that contains vitamins D and calcium.

The effects of red light on mitochondria may be true in skin cells. Light doesn't penetrate the skin of the testicles because they are internal organs. There are light therapy treatments that work on the skin, but they aren't really a good way to increase testosterone production just because there is light shining on the scrotum.

Some guys think it must work. Andrew McGovern was correct when he said that people don't trust the mainstream information when they embrace light therapy. It is the same thing all over again. Shining a light on your balls feels like a secret health hack that doctors don't want you to know about, and yet you can do it yourself for free with the sun. You can feel like an expert by researching light therapy devices, then checking your email and calling your mom while standing in front of one with your pants down, as biohacker Ben Greenfield wrote about his experience.

It feels a little bit special. Remember the lady who posed for a picture with her butt and buttocks? She said that being a woman has connected her more to her womb space, which sounds like the way she felt when she was a man.

The secrets of testicle tanning are revealed. Don't be surprised if the next trend goes the opposite way, like sitting with an ice pack on your scrotum, which is supposed to increase your testosterone.
