5 studies you may have missedHere's a roundup of five medical studies published this week that might give you new insights into your health, mind and body. Remember, correlation is not causation – so if a study finds a connection between two things, it doesn't mean that one causes the other. Keep your phone out of your pocket – your sperm will thank you Since guys don’t usually carry handbags, they tend to keep mobile phones in their pants pockets. A recent study from the University of Exeter suggests this may not be a great idea. That cell phone could actually have a negative effect on your sperm quality. The review looked at findings from 10 studies, that included almost 1,500 samples of semen. To evaluate the mens’ sperm quality, the scientists measured viability (the ratio of sperm that were alive), motility (the ability of sperm to move) and concentration (the number of sperm per unit of semen). Compared to a control group, the percentage of sperm showing normal movement dropped by 8% among men who pocketed mobile phones. This group's sperm's ability to survive also decreased in about 9% of the samples. The scientists write that the individual risk for sperm damage depends on how long a man keeps his phone in his pants and how much electromagnetic radiation the phone emits.

Now Harvard researchers say eating red meat in early adulthood also increases a woman's risk of breast cancer. The scientists analyzed data from 88,803 premenopausal women. During 20 years of follow-up, the team looked at the diets of those who developed breast cancer. The result: higher consumption of red meat was associated with a 22% increased risk of breast cancer overall. Women who ate more poultry, fish, eggs, legumes and nuts had a lower risk for breast cancer. Read more from BBC The 'trust and cuddle-hormone' has another important purpose Oxytocin is often referred to as the “trust and cuddle hormone” because of its role in maternal nurturing and friendship. Researchers at the University of California, Berkeley, now say that oxytocin is also essential for healthy muscle maintenance and repair. Their recent study showed that injecting oxytocin under the skin helped animals' muscles heal better. Oxytocin is the first “anti-aging” molecule approved by the Food and Drug Administration for clinical use. That’s why the study presents oxytocin as a future treatment target for age-related muscle wasting. Read more from UC Berkeley Bad-breath bacteria does more than turn off your date Scientists from the University of Pennsylvania have found the bacteria that cause gum disease also create an imbalance in your immune system. Their recent study revealed that the periodontal bacterium Porphyromonas gingivalis disarms the immune system, leading to periodontitis, with inflammation and bone loss. The gum germs block the immune cells' killing ability and cause inflammation. The dead cells become nutrients that the bacteria feed off of. “The result is a vicious cycle that exacerbates periodontitis," the researchers write. The team’s discoveries open up new targets for periodontitis treatment. Read more from University of Pennsylvania Heart disease can hurt your mental health A healthy mind needs a healthy body. According to a new study, keeping the heart healthy is also a great way to keep your brain fit. The research examined 17,761 individuals with normal mental function and then re-evaluated them after four years. The scientists found that the risk for cognitive impairment is greater for people with poor cardiovascular health. A deficit in learning, memory and verbal skills developed in 4.6% of people with the worst heart health and in only 2.6% of those with the most healthy hearts. The study doesn’t explain the mechanisms that may have led to the findings. However, the study’s author, Evan L. Thacker, said “undetected subclinical strokes could not be ruled out.” To learn more visit Health.com

New study confirms that obvious stuff is obvious.
Good one!
That's how research scientists keep the grant money flowing in, though. Just as the so-called "climate change experts"!!
I am over 50 year old, can I put the darn phone in my pocket and stop worrying about my sperm count now? I have a couple of great kids so I think I will stop while I am ahead.
I am 71. Is it OK to have my phone in my pocket?
lol my thoughts exactly.... lol 2 kids me too, enough!!
Sperm is a liability anyway.
I'm female & have no worries about the health of my sperm, but I found this report meaningful. Knowing that the radiation from mobile phones damages nearby sperm suggests that radiation from mobile phones is probably not too great a thing to constantly expose ANY of our cells to. A little thought as to how we can have the convenience of ready access to mobile phones while not having them against our bodies for extended periods and without shielding seems prudent.
What happens if you carry your cell phone in your back pocket? Will it still interfere with your sperms or should you then worry about colon cancer?
Iam 75, I keep mine in my shorts on vibrate...I am thrilled when friends call
Hey Ron... why don't you post your phone number. You'll have a night you'll never forget.
Talk about some more crap medical "studies"! What is this BS they are trying to feed to the American public? Burgers may increase your risk of breast cancer?..um yeah and every other cancer you can get. Having heart disease will make you dumb? Really?!?! Heart disease isn't genetic and there are many ways to prevent it so all-in-all, if you have heart disease, you're already dumb for not doing what you can to prevent it...by the way, step one...put down the cheese burger and you'll be two steps ahead of preventing cancer and heart disease; two of their medical studies solved.
Thank you Doctor! Do you take Medicaid patients?
Heart disease IS also caused by genes. You don't know what you're talking about saying it's all diet. Stress response also plays a role which can also be linked to genes.
This is up there with the stupidest things CNN has allowed on its front page (to be fair with all the opinion pieces it's got a ton of company). Sperm counts going down. haha
Wow a study published on a website called "Science Direct". That sounds legit. Move over PUBMED. For every study that has come out claiming cell phones have a negative impact on sperm/brain/bone/connective tissue, there has been 5 studies of equal or better that have discounted it.
Yeah – great to see such "wonderful" science being used to frighten people. You might think that the science editor of CNN would like to inform people of the truth. I guess it is more a case of trying to increase ad revenues – dam the truth.
Actually, science direct is a database of peer-reviewed journals books just like pubmed. It is legit as it is run by Elsevier, the company that has been publishing medical and scientific journals, textbooks and reference materials since the 1800s. Anyone who studies science and medicine will know this company very well. Besides all their textbooks and reference materials, they currently publish over 2000 peer-reviewed journals.
Not knocking your other point, just thought you would like to know that it is a legit site.
To put it simply (because you obviously need simple) Science Direct is an extremely well known portal to access articles from a wide variety of journals. When you base your sarcasm on ignorance you reveal what a truly sad person you are. Also, Pubmed is just a database (something you might also want to learn about).
Perhaps you should learn what Science Direct actually is... but to save you time, it's a scientific journal database. If you're doing research of scientific literature, it is a fantastic resource.
Seems I should've refreshed the page first... Ah well, now you've been told plenty of times.
Also, don't walk around with a PAY phone in your pocket!
I carry my phone in my pocket all the time and my wife says my sperm quality is fine
Nice. I'd like to know your wife's opinion on my sperm quality.
That's funny, she said the same about mine..

um, DNA cannot be damaged by non-ionizing radiation, it is non-ionizing...
I put my phone, wherever I damn please. I am 82, but that is not the point.
So I can talk, text, annoy and bother others... I duct tape my cell to my head while in public, music blaring. Is that dangerous to the lil swimmers, or just my brain?
To paraphrase the late great Mae West: "Is that a phone in your pocket, or are you just glad to see me?"
You mean I didn't have to pay all that money to get my vas deferens snipped & tied off, didn't have to go through my nuts feeling like they'd been put through a blender, didn't have to shell out all that money because it's a voluntary medical procedure?
ALL I HAD TO DO IS CARRY MY PHONE IN MY POCKET?
Oh, wait. I'm gay. I can't get my sexual partners pregnant. Guess I didn't need that vasectomy after all!
No, that's not true. But here's what you gotta do: Stick your $#)W#$ in a wood chipper and hit the switch.
Guaranteed you'll never have to worry about knockin' your chick up ever again. Ever.
He doesn't @#$# chicks. He's a gibbon monkey.
Hogwash. Unless your carrying an 80s style phone in your pocket. I am proof as my wife is about to give birth to twins. I share interesting photos on imageskeep.com
Men, keep the phones in your pockets right close to the one-eyed snake and help reduce the population!
The "wireless world" we are in is "man made". Asbestos was man made. DDT was man made; and the list goes on. My android see's 10 WiFi hot-spots while I'm at home. This WiFi radiation is passing through my body. The EMF ionizing radiation is in the S-band (about 2.5 Gig Hz) which is about the same frequencies used in Microwave ovens. Think about it.
There is a huge difference between your Microwave and WIFI. WIFI power is in milliwatts range and your microwave oven is 1000 watts. milliwatt 2.4-2.5 Ghz will not penetrate your outer skin vary far. In fact, it only lightly interacts with the human body and that lite interaction in the future will be used for gesture control of other systems in your house.
1000 Watts at 2.4ghz IS a big deal and that is why, MW ovens are shielded against leakage. That being said, i have no doubt at all that even low power high frequency radiation to the scrotum WILL cause issues.
More government funded studies of dubious practical worth. As for cellphone storage, I keep mine between the butt cheeks to deter theft.
All of you guys coming on here telling us that these studies are dumb just because YOU are older than Methuselah and your wife is about to give birth to octuplets are idiots who clearly don't understand science. Could you just S-T-F-U already?
Let's make sure Justin Bieber has at least 4 cellphones in his pockets all the time.
"Heart disease can hurt your mental health" - See Dick Cheney.
"Heart disease can hurt your mental health".
Correlation is not causation. Need to report more stats from other lifestyle behaviors before making this statement.
I keep my phone in my pocket because I have it set on vibrate.
Call me.
It would be better off if most of you mooks didn't reproduce at all.
I agree. The idiocracy is outgrowing the GDP.
There's NO Room for a Cell Phone in my Pocket....OBAMA's Hand is already in there!!!
He jerking you?
I must let all my brothers from the hood, know to keep the phone in their pockets, maybe even 2 phones
I put my phone in my pocket yesterday and now I can't find it.
You know you need a new girlfriend, when she'd rather put your cell phone in her mouth.
Especially when it goes off and vibrates.
You've been replaced, Bruno....
Gosh! The prospective precedent for male birth control; just make 'em carry arounf an overpowered cell phone in their pockets all the time, past age 13.
But that second one is going to royally tick off the Beef Council. How soon before we hear a counter "study" that disproves it?
Global warming is a sure thing. That's because we know we are on the final phase of the current warming cycle of 120,000 years. Prior to this cycle we had three confirmed cycles happen with almost the same results. Earth cycles through cold and warm all the time. Vostok data set shows we are closing in on the latest high levels of C02 and sulfur dioxide. Temperatures are also very close to the melting of the poles, which has happened enough to find samples of leaves and trees at the south pole. So, yes, Barry, global warming is guaranteed according to the Vostok ice core data. It will happen and Earth will survive. As for humans, not so much
Sorry, my browsers got crossed up.
yup – we will hurt ourselves before we hurt earth, can I assume that?
personally, I do not think we have enough data to make intelligent decisions. not that we shouldn't be mindful of the environment per se, but we have a tendency to commercialize and politicize which does us no good anyway – as it is not seriously addressing the issue, just making it serious business (of money). green is expensive...
it's like smoking – smoking is bad, I do it, I shouldn't.. yet the government seems to rely on people's addictive behaviors, smoking being one, to profit by it..
the surgeon general's warning is up in smoke – no good in this sense.
A one-night stander acquitance of mine liked to keep her cell phone on vibration between legs.
She prefers a phone to giving you a second shot? Better work on your technique. I have a line of videos set for release this fall. Watch for them.
"Hey baby-I don't need a rubber, I keep my phone in my pocket!".
Interesting article, I too have been trying to avoid to much red meat for many reasons!!
However, men who use a cell phone clip, instead of placing their phone in their pocket, have a reduced ability of actually getting laid by 80%, rendering the benefit useless.
There is no association between diet and cancer, cardiovascular disease or any other ill except obesity. We need to get off the stupid diet concepts that have been part of our culture for over 50 years. I did research on this and the literature does not support any association of diet with a major illness.
There is a correlation, but there is also a correlation between the marriage rate in Kentucky and the number of people who drowned after falling out of a fishing boat. Correlation means nothing.
why would anyone put something warm next to his testicles? 🙂
Aaahhhhh why not?
HAHAHAHAHAHA what a bunch of silliness.
After reading this, I moved my mobile phone from my pocket to my underwear.
There is a NEW study out just seconds ago that indicates fabricated Medical/Global warnings are now available on Gluten Free toilet paper.
Use John Wayne toilet paper. Rough and tough and doesn't take crap off no one.
I am gay. Should I avoid putting my cellphone in my back pocket?
Never mind what you put in your pockets. Stop sticking things up your wahoo that don't belong there.
That peg doesn't go in that hole, Nancy...
Be kind to your sperm. And stop shooting us on the ceiling and the drapes.
Gawd you people make me mad.
Cool, I found a new form of birth control. I'm keeping my phone in my underwear from now on.
It's gonna stink when you put it to your ear.
Do you care?
gubba gubba!
Put me in your pocket and I'll talk dirty to you.
Then I'll butt call your old girlfriend.

Umm, but holding the cell phone up to your brain? No problem...
In the 1990's my company made antennas for 90 percent of the world market. We built a faraday cage to do the first testing for harmful effects. We did testing to create a baseline. The engineer in charge had the baseline test results on his laptop, which he took home for the christmass holidays. While leaving town, his car was hit by something big that sent his car into the air and crashed in a ditch. He died. There were no witnesses. The vehicle that hit him was never located. When police arived there was nothing missing except his laptop with the results.
After the holidays I was told to destroy the cage. No more testing was done and nobody asked why.
See, cellphone radiation could kill.
Motorola may have had 90 percent of the world cellphone market at some time, (not even Nokia?) but I have to call Bullfeathers.
More people should keep them there. I'm tired of all the stupid people breeding.
Da Faq. Maybe men should keep their phones nestled next to their balls. Reduce the chances of getting a girl knocked up, yes?
I'm 73 years old. Can I keep my phone in my pocket?
I looked at the phone study, and wrote it up here:
http://scienceblogs.com/gregladen/2014/06/14/does-keeping-a-cell-phone-in-your-pocket-reduce-male-infertility/
The tl;dr: maybe a little but for benign reasons. If fertility is important to you and you are a man, don’t put hot things in your pockets. This may fall into the category of switching from tidy whities to boxer briefs.
Maybe more men should keep their cell phones in their pockets. In fact, I think this practice should be widely promoted. Perhaps jock strap cell phone pockets could be developed. I would gladly be on a team to design one. Men could sleep with their cell phones charging while in these jock strap pockets. We might eventually reach a sustainable global population if these practices were followed.
