Researchers took a group of healthy male twentysomethings and forced them to get by on only five hours of sleep a night for a full week. Results from a 2011 study back up this claim. Breus, that’s because “most testosterone production occurs during sleep, primarily during REM sleep, the period of the night associated with dreaming.” This means that less sleep results in less testosterone, but it’s actually more complicated than that: REM sleep doesn’t really start kicking in until you’ve been asleep for four hours (see graph below), so if you’re trying to squeak by on a few hours of sleep a night, you’re depriving yourself of prime testosterone-production time. This is exactly what happens as you age - your body produces less testosterone and as a result, your gonads start to shrivel.īut age isn’t the only thing that reduces testosterone output poor sleep does, too. Your balls are essentially testosterone factories, then, but when there isn’t as much testosterone being produced, your balls begin to close up shop and your testicular cells atrophy and die. Testosterone plays a vital - if wildly misunderstood - role in men’s health: The hormone isn’t only a key player in male fertility, it’s also responsible for boosting men’s sexual libido, muscle mass, bone density, fat loss, energy, mood and cognitive functioning. One of your testicles’ main jobs is to produce testosterone (the other is to produce sperm).

Low Testosterone and Sleep: What Poor Sleep Is Doing to Your Balls That means that skimping on sleep doesn’t just shrink your balls - it degrades them. No, what the Danish study found was an actual reduction in cellular volume, what doctors call “testicular atrophy.” Men with the worst sleep had 5 percent less testicular volume than men who slept well.
GUYS WITH TINY BALLS PORN SKIN
To be clear, we’re not talking about the kind of temporary ball shrinkage you get when you jump into a cold pool (which happens because cold temperatures make the skin surrounding your nads tighten, without actually affecting the size of your testicles). But it’s almost certainly not literally the case: A 2013 Danish study examined the sleep patterns of nearly 1,000 healthy men and found that guys who slept little, or slept poorly, had significantly smaller testes than their well-rested brethren. Now, several of these men (and one in particular, obviously) probably lied about how little sleep they need simply because they want you to think of them as hyper-macho, sleep-is-for-the-weak alphas - to believe, essentially, that they have a giant, clanging set of balls. The assumption is that getting by on just a few hours of sleep gives them a competitive edge - as Trump once put it, “How does somebody that’s sleeping 12 and 14 hours a day compete with someone that’s sleeping three or four?”

What do these rivals have in common? All of these men are known for sleeping only four to five hours a night. Twitter’s Jack Dorsey and Apple’s Tim Cook.
