Shouldn’t laptops be on your lap? How does WiFi exposure affect sperm motility and DNA damage?
“It’s impossible to imagine a modern, socially active man who does not use mobile devices and / or computers with Wi-Fi capabilities. ”Could cell phones or wireless internet being harmful to male fertility? You may remember earlier that I talked about how the sperm of men who use Wi-Fi doesn’t usually get along as well, but that was an observational study. You don’t know whether Wi-Fi actually damages sperm until you put it to the test, the subject of my video Does laptop WiFi reduce sperm count?.
The title “Using laptops connected to the Internet via Wi-Fi decreases the mobility of human sperm and increases the fragmentation of sperm DNA” gives all gone. This was “the first study to examine the direct effects of laptop use on human sperm”. As you can see in mine at 0:43 Videowho have favourited DNA fragmentation data in samples of human sperm placed near and far from a laptop with an active Wi-Fi connection suggests that one may not want to place a Wi-Fi device near the male reproductive system as it “can affect human sperm quality”.
In fact, the Wi-Fi exposure can to decrease increase the motility of human sperm and sperm DNA fragmentation, but the effect is small. Will a 10 percent decrease in “progressively motile” sperm really make a difference? Fertile men set hundreds of millions free. What remains to be done is a study Looking for at jumping baby endpoints. Do men randomly assigned to a specific WiFi exposure have a harder time having children? It is actually a more difficult study than you might think. Men can’t just go without cell phones and laptops for a day. Yes, we produce millions of new sperm every day, but it takes months for them to mature. The semen you get pregnant with today started months ago as a preconceived notion. So you can imagine why such a study has yet to be done. You’d have to randomize men to essentially avoid wireless communication entirely, or maybe develop some kind of Faraday cage underwear.
Another reason you might not want to use a laptop is on the lap that the heat generated by the laptop, with or without WiFi, “can warm men’s scrotum”. Hollowing out The whole point of owning the scrotum comes first – namely to hold the male gonads in such a way that “the testicles and epididymis are exposed to a temperature that is a few degrees below the core temperature of the body”. It all goes back to a famous series of experiments guided 1968.
It was an instructive study, one might say, as the subjects’ skrota were heated with a 150 watt lightbulb … In some of the experiments, the heat of the 150 watt lightbulb was increased by using an ordinary reflector, even though the bulb was alone was just as effective when placed a little closer to the skin. This was easier, but more likely to result in accidental burns from contact. ”(Why can’t I seem to get Jerry Lee Lewis’s“ Great Balls of Fire ”out of my head?)
Now we have nice, cool fluorescent tubes instead of 150-watt light bulbs, but heated car seats remain a “testicular heat stress factor”. Saunas are not a good idea for men try to understand. At 2:52 in mine Video, I show a graph of sperm counts before and after the sauna. Sauna exposure apparently reduced sperm production in half, and sperm count was still going down three months later. However, there was an apparent full recovery after six months. That’s why you might want to walk with boxer shorts, not briefs or even walk Command. But who makes money by going au naturel? Enter the “scrotal cooling” industry though a review noticed that a “more acceptable scrotal cooling technique” really needs to be developed. Why? What are the researchers referring to?
It seems that the “devices” Second hand Achieving testicular cooling ”are currently on the market“ not practical for everyday use. One device was a domed ice rubber collar filled with ice cubes, ”and another resembled a freezer gel pack that“ is put into the participants’ underwear every night ”, but don’t worry, it thaws in three to four hours,“ thereby ”cooling Effect. “Holy snowballs, Batman!
Don’t, I repeat, don’t place an ice pack on your scrotum. A few frozen peas and carrots in a strategically placed surgical glove can cause frostbite. (Maybe one day vegetables can harm you!) Publications Liquid (water or alcohol) too keep the scrotum wet “and finally a device fastened with a belt that” reaches “[s] Scrotal cooling ”with a continuous flow of air.
With so many options to choose from, do laptop users really do it? to need Protection against scrotal hyperthermia? You don’t know … until you put it to the test. Indeed there was an increase in scrotal temperature found In laptop users, scrotal temperatures rise to a feverish 5∞ Fahrenheit.
A little heat of the testicles didn’t do it sound so bad until I read this case report: A previously healthy 50-year-old scientist typed wrote a report one evening, comfortably seated in his favorite chair with a laptop on his lap, but woke up the next day with “penile and testicular vesicles” which then “broke open and developed into infected wounds that caused severe suppuration.”
Even third degree burns were made reportedthat require skin graft surgery. In one report, a man drank 12 units of vodka and passed out while watching a movie on his laptop resting on his bare thighs. The laptop burned his leg. The surgeons called for a “public awareness campaign” to “educate the public about the risks of using a laptop in the truest sense of the word”. That’s one approach, but why not educate the public to drink 12 units of vodka instead?
THE CENTRAL THESES
- Researchers suggest keeping Wi-Fi devices away from male reproductive organs, as Wi-Fi exposure can reduce the quality of sperm, reducing their motility and increasing their DNA fragmentation.
- The heat generated by a laptop with or without Wi-Fi functionality is another reason not to place the device on your lap as it can heat men’s scrotums. This undermines its functional purpose – that is, to hold the male gonads in such a way that the testicles and epididymis can be exposed to a temperature a few degrees below core body temperature.
- Similarly, heated car seats can heat the testicles, and the sauna has been found to cut sperm production in half, although there was a full recovery after six months.
- The “scrotal cooling” industry arose with devices that are supposed to achieve “testicular cooling”, such as rubber sleeves for filling with ice cubes and freezer gel packs.
- Laptop users were found to have a 5 ° F increase in scrotal temperature, which seems insignificant. However, in one case report, a previously healthy middle-aged man typed a report with his laptop on his lap and woke up the next day with blisters on his penis and scrotum that broke and leaked pus.
- In fact, third-degree burns have even been reported while using laptops on the lap that required skin graft surgery.
This may not only be an issue for men, as I described in my video Do Cell Phones Reduce Sperm Count? and Flashback Friday: Do Cell Phones Lower Sperm Count? & Does laptop WiFi reduce sperm count?
