Cell Phone Use May Reduce Male Fertility, Austrian-Canadian Study Suggests
ScienceDaily (May 19, 2011) Men who have been diagnosed with poor sperm quality and who are trying to have children should limit their cell phone use, a new study suggests. Researchers in Austria and Canada have found that while cell phone use appears to increase the level of testosterone circulating in the body, it may also lead to low sperm quality and a decrease in fertility.
The research team at Queen's and at the Medical University of Graz, Austria, discovered that men who reported cell phone use had higher levels of circulating testosterone but they also had lower levels of luteinizing hormone (LH), an important reproductive hormone that is secreted by the pituitary gland in the brain.
The researchers hypothesize that electromagnetic waves (EMW) emitted by cell phones may have a dual action on male hormone levels and fertility. EMW may increase the number of cells in the testes that produce testosterone; however, by lowering the levels of LH excreted by the pituitary gland, EMW may also block the conversion of this basic circulating type of testosterone to the more active, potent form of testosterone associated with sperm production and fertility.
More in-depth research is needed to determine the exact ways in which EMW affects male fertility.
Results of the research appear in the journal Andrologia, published by Wiley-Blackwell. In addition to Shamloul at Queen's, authors include T. Gutschi, B. Mohamad Al-Ali, K. Pummer, and H. Trummer at the Medical University of Graz.David

The objective of the present retrospective study was to report our
experience concerning the effects of cell phone usage on semen parameters.
We examined 2110 men attending our infertility clinic from 1993 to October
2007. Semen analysis was performed in all patients. Serum free testosterone
(T), follicle stimulating hormone (FSH), luteinising hormone (LH) and
prolactin (PRL) were collected from all patients. The information on cell
phone use of the patients was recorded and the subjects were divided into
two groups according to their cell phone use: group A: cell phone use (n =
991); group B: no use (n = 1119). Significant difference was observed in
sperm morphology between the two groups. In the patients of group A, 68.0%
of the spermatozoa featured a pathological morphology compared to only 58.1%
in the subjects of group B. Patients with cell phone usage showed
significantly higher T and lower LH levels than those who did not use cell
phone. No significant difference between the two groups was observed
regarding FSH and PRL values. Our results showed that cell phone use
negatively affects sperm quality in men. Further studies with a careful
design are needed to determine the effect of cell phone use on male
Armed with a petition containing about 160 names, Colleen Genno this week urged city council not to make available WiFi technology at the downtown building.
"As a mother, I need to look out for my children, and for all of the children in this town," Genno said. "I'm also concerned about the adults, the library staff."
Heart palpitations, migraines, breathing problems, and memory loss are among a slew of symptoms linked to WiFi exposure, Genno added in a presentation to council.
"A lot of schools have removed WiFi because of children and teachers showing negative response to it," she said.
Genno removed her four-year-old son from a local school in October after he began experiencing troubling symptoms, including nosebleeds and behavioral problems.
When the principal refused to provide a schedule detailing when laptops where being used, Genno pulled her son from the school.
"When I removed him, all of these things went away," she added.
Genno recommended that WiFi technology not be employed at the new library, and recommended that plugs be installed at study carols for clients requiring Internet access.
"This would provide a safer alternative to WiFi," said Genno.
She noted WiFi technology is in place at the temporary library and is used, on average, by four people per day.
"It is not a huge demand, certainly not something that they can't do in a safer way," Genno said.
Coun. Linda Murray noted the World Health Organization stated it had no scientific evidence to show wireless networks cause illness.
Genno said that many of the studies to date are flawed or were industry-funded.
"We have the choice of whether we are going to use a cell phone or not, but children don't have the choice," she added. "And we don't have the choice if we are being subjected to WiFi that we don't even realize (is present)."
Coun. Tony Madden said council isn't qualified to make a decision on wireless technology and must rely on the federal government for guidance.
"We are not experts in that field, and so we have to rely on the science of the day," he said. "Current science of the day, as endorsed by Health Canada, says that it's safe.
"If there is anecdotal or conflicting research that states otherwise, I think it is incumbent upon Health Canada to put that issue to rest," he added.
