Protect Your Sperm: Switch From Briefs to Boxers

Your balls are the most vulnerable part of your body (maybe your neck comes first and your balls second, but it’s close). One good hit to your balls can take you out for good.

You would think that given how important and vulnerable your testicles are, you would have evolved to protect them better.

Your heart has a rib cage to protect it but your balls have… nothing? Even the skin on them is thin and there’s no fat around it to cushion impacts!

Your testicles need to be cooler than your body

Your testicles need to be 2-4°C cooler than your core body temperature (33-35°C vs 37°C).

This is why they hang outside the body, why the skin there is paper thin, and why there’s no fat to surround it.

It’s all so that they are able to lose heat more easily.

You even have specific muscles that pull your balls up when you’re cold and hang them lower when they’re hot (this is why the sack appears to “breathe”).

There is decades of research on heat based contraception that show that artificially warming the testicles can suppress sperm production for weeks to months.

Transient scrotal hyperthermia, such as 43 °C for 30 minutes daily, has demonstrated contraceptive efficacy in small human trials, achieving infertility in most participants within 2–3 months, with oxidative stress implicated in the spermatogenic suppression. Recovery of normal semen parameters occurs post-cessation, generally within 3–6 months, underscoring its reversibility compared to vasectomy.

This is why I always tell my male employees to never use their laptops on their laps. You are overheating your balls.

Boxers are superior to briefs

You should ALWAYS wear boxers instead of wearing briefs. Boxers are looser and allow much better heat dissipation than briefs.

Briefs do not have enough space and do not allow your balls to hang properly.

They force the testicles close to your body and always keep them hot.

There are many studies that show the association between lower sperm count and quality and men who wear briefs.

One that had 656 participants at a fertility center found:

Men who usually wore boxers had (compared with men who usually wore briefs and other tight underwear):

• 25% higher sperm concentration
• 17% higher total sperm count
• 33% higher total motile sperm count
• 14% lower FSH (hormone that goes up when your testicles aren’t working well)

Switching from briefs to boxers is a very simple way to improve your sperm health.

It’s one of those zero effort fixes that produces measurable results (like switching from regular coke to coke zero).

Total no brainer decision. Just don’t be cheap – buy the highest quality cotton boxers you can afford (I would not use cheap artificial fabrics around my balls unless I was really short on cash).
