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. Read more from TIME Eating too many hamburgers may increase your breast cancer risk Past research has shown that eating a lot of red meat increases the risk of bowel cancer. 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

I've heard multiple reports about how having a mental health issue can lead to heart problems. Now they're saying heart problems lead to mental health issues. Is this another chicken v. egg case or are researchers just trying to scoop up some presedence?
Nope. They're trying to scoop up some government grant money and need to produce a "tangible" result.
If I had heart disease, I think I would be a little depressed too.
One theory is that heart disease leads to less oxygen in the brain, which leads to depression and other issues. It's actually a plausible theory. We'll see what the next round of studies turns up. This scenario was actually attributed to my grandmother's mental decline before her death.
Ah., how about the fact that we are meant to put these devices to ours heads nevertheless next to our nuts?
What about the guys that walk around with a cell phone next to their head all day?
Which head?
I can always take off my tin foil hat and use it to wrap my package
Thanx for the tip and all, but I let my ladies worry about my sperm "quality"... :0)
What have I learned from health studies? Everything is trying to kill you.
I don't keep my phone in my pocket because my penis keeps dialing New Zealand.
That proves they are misinterpreting the data. It is only men with low quality sperm in the first place that keep their phones in their pockets. Men with high counts tend to be more active and that requires dialing specific tele# numbers by whatever means. I think dialing by hand keeps the sperm count high.
Well that will save me some money on a vasectomy.
there are things that are very harmful to our human body
all these posts were so funny!! Thank u guys for making me laugh!
Well that it for now until the next study comes out with the opposing "facts".
Uh huh, and milk is bad for you one week, and good for you the next. Its fear mongering and nothing more.
Milk IS very bad for you if it's not from organic, grassfed cows! And even then, many people have milk allergy that causes acne and other negative effects. So yea, I loved milk but I have stopped drinking it.
Prove that milk from "grass fed cows" is any better for anyone that milk from cows on other feeds. Go ahead. Cite your sources.
The way men are portrayed in the media and in everyday life, I'm surprised people are still concerned about our health. Usually we're seen as slobs and neanderthals.
I used to carry my cellphone in my bra until I had a cat scan of my chest and a spot was seen on my breast.
Six months later another cat scan and it was still there. I had changed jobs so didn't carry my cellphone in my bra and Dr ordered another cat scan and mammogram. Nothing not a speck.
I'm just telling you my experience.
Hmmmm ok I will put my phone in my mouth. Boooooooooooo
if you read the instructions that came with your iPhone it specifically states not to get the iPhone any closer than 4 inches to your head, due to possible radiation poisoning. If you sat down and read the rest of the instructions you would probably stop using cell phone technology that is if you're smart enough to understand what it says oh and read.
The instructions say that? Where? Can you post a link to them?
So you can use your cell phone to get a free vasectomy? Sounds like a good deal. Let's jump on it before the cell phone companies realiize what's going on and get health insurance involved.
Dial "S" for sterility!
Background checks for cell phones !!!
I've kept my cell phone in my pocket since 2000, and I have 3 kids. I had a vasectomy and it took 4 samples for me to be clear of any sperm. I'd say I beat the odds.
Scientists have been bad-mouthing birth control for years. Leave my cell phone alone.
.....is there a correlation between having hair on my palm and being single?
I am 65 years old. My swimmers are not able to make it across the Channel if they wanted. They need the phone in my pocket anyway, they have their own Facebook account.
a new form of birth control. Now men won't feel slighted by Obamacare only covering womans BC. And with the Obama phone – it is free as well !
more like dont put your cellphone in your pocket because the nsa will not be able to hear your muffled conversation
Holy Cow! Another 'study'! And here I am still trying to digest the 'study' that discovered school girl pregnancies result from their addiction to motherhood.
