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.
