While the results are inconclusive, this is an important first step to more rigorous studies that research the link between male infertility and cell phone electromagnetic waves

A team of international researchers has found that cell phone use may have negative effects on the fertility of men.

Rany Shamloul, study leader and a postdoctoral fellow in the Department of Pharmacology and Toxicology at Queen's University, along with a team of U.S. and Austrian researchers, have found that male cell phone users have lower quality sperm than those who do not have cell phones.

Shamloul and his team conducted the study between 1993 and 2007 at an Austrian infertility clinic, where the sperm of over 2,000 men had been collected and examined. Men were asked if they owned and used cell phones at the time of collection, and those who used one on a daily basis were labeled cell phone users. 

After studying the collected sperm and cell phone users and non-users, the researchers found that men who regularly used cell phones had higher levels of circulating testosterone, but lower levels of luteinizing hormone, which is a key reproductive hormone that secretes by the pituitary.

The researchers' theory is that the electromagnetic waves that cell phones emit increase the number of testosterone-producing cells, but also lower levels of luteinizing hormone. This, in turn, may negatively impact fertility. 

But at this point, these results are not conclusive. The researchers need more time and research to determine if the cell phone use is really what is causing the low quality sperm, or if it's something else. 

Whether cell phone use is the culprit or not, this is an important first step to more rigorous studies that research the link between male infertility and cell phone electromagnetic waves.

What was the general health of cell phone users vs. non-users? Which geographic regions had more cell phone users than non-users? What were the occupations of users vs. non-users? Too many uncontrolled variables for this study to be of real use.

You would know about 'uncontrolled variables' if you read the study itself. Did you?

Exactly... that's why it's important to avoid jumping to conclusions from the study... too many unknowns.

Actually I was somewhat surprised that the researchers postulated that the cell phone emissions were causing alterations in cells, when there's no real evidence to support that yet, and there's actually evidence to support it's HEAT from the cell phones that might be causing the issue.

This study looked at users who kept their phones in their pockets vs. those who kept their phones in holsters and found the heat appeared to be causing a decrease in sperm counts.

I'd suspect something similar is at play here.

This is an important distinction because if it's heat and not some sort of emissions related issue, lots of other things could present similar issues -- hot beverages, laptop computers, saunas, hot tubs, hot showers, etc.

Maybe the study actually showed that cellphone users wear tighty-whiteys, whereas non-cellphone users wear boxers.

Just sayin...

(no I didn't read the whole article...just skimmed it and the above thought came to mind)

This study, like most of this type, proceed from a false premise that everyone has the same level of fertility in the first place and that the cell phone use MUST be the catalyst for some change. When, in fact, we don't know if there WAS a change in fertility hormone levels in the first place from person to person.

Also, like women, men have hormonal "cycles" too that effect our potency. I see nothing in the study about this being accounted for.

i'd guess that it's probably tied to stress more than it is cell-phone use. i have a cell-phone; i don't use it on a daily basis. i'm very much a "type-b" personality.

both men and women who have excessive levels of stress have been documented to have lower fertility rates. in my opinion/experience, those same individuals--in this day and age--are usually frequent cell-phone users.

Yeah, this reminds me of the violent video games linked to school shootings statistics: Kids who shoot other kids in school had played violent video games. Yes, most boys play video games. Does that mean that teen pregnancy is linked to playing with baby dolls since all girls who got pregnant when they were teenagers owned baby dolls.

Correlation != causation

This is yet more proof that anyone can cherry pick statistics to try and prove their point.

Cellphone use could really impact male fertility if you end up dead after crashing your car while talking on the phone.

Though if only wounded - and then cared for by a hot nurse - maybe it would increase fertility.

Wouldn't it be ironic, that the stud muffins that get all the dates end up losing their fertility, and thus, their ability to procreate?

People who are infertile use cell phones? It's not like 80-90% of people in modern countries use cell phones these days.

Seriously. Some studies say phones have an effect on our brains so maybe this is natures way of making sure those that have gotten stupid from being on the phone does not pass on the stupidity.

Personally, when I see someone pull a phone out of their crotch I'm not at all concerned that they might not be able to reproduce.




And the bad side?
By Belard on 5/23/2011 7:24:00 AM , Rating: 2
Given that the cellphones in the the 90s were (are supposed to) far worse than todays phone and causing brain damage.

What is the down side? Is it caused by using the phone by the head or having it in our pockets next to our junk? (I think the later).

With human over-population, anything to slow the growth of mankind is a good thing.




Prevalence
By Paj on 5/23/2011 8:04:12 AM , Rating: 2
Given how prevalent mobile phones are these days, and how pretty much everyone who lives in any big city in the developed world is bathed in electromagnetic waves of various guises at all times throughout the day, I would imagine that there has been plenty of time for any negative health effects arising from this to have presented themselves.

So I've got to stop keeping the cellphone ehm..down there when I drive?

Every time I brake strong , if I don't keep it "there", it zooms on the windshield and rebounds under the clutch pedal...




Free Fertility Control?
By Angstromm on 5/23/2011 7:45:34 PM , Rating: 2
Well, perhaps cellphone companies can charge extra for male fertility control. Think of the additional accessories that could be sold: upper thigh holsters; cups w/ cellphone holders; cellphone handy wipes to remove that scrotal aroma; anti static cellphone covers so hair doesn't cling on; special smegma removal cleaning kit; etc. I say we start a company now!




what doesn't?
By superstition on 5/23/2011 9:06:44 PM , Rating: 2
It seems that basically everything new about modern life decreases sperm count and viability.

But, that's not stopping the planet from being increasingly overpopulated. Maybe we should hope for lower sperm counts?
