Research conditions damage sperm not mobile phone signals

Fertility ResearchPoorly designed exposure set-ups are to blame for sperm damage in lab experiments testing the effects of mobile phone signals, according to Professor Alexander Lerchl of Jacobs University Bremen in Germany.
“Research in this area of research is notoriously difficult and prone to errors,” said Professor Lerchl in an opinion piece published in the Asian Journal of Andrology.
“The possible impact of cell phone ‘radiation’ on male fertility is a hot topic, mainly because some scientists, politicians and certainly large parts of the public are fascinated by horror scenarios such as this one. As long as poorly-controlled studies on the effects of RF-EMF exposure on sperm function and fertility continue to be conducted and published, this will not change.”
Professor Lerchl said a lack of knowledge about how mobile phone technology worked and a poor understanding of how to set up experiments involving radio waves had led to several weak studies and inaccurate or false results.
He said there were a number of examples of erroneous studies which had to be retracted, including three Japanese papers involving tests on rabbits which had to be withdrawn after they were published in three renowned journals in 2009 and 2010.
“According to the authors, who allegedly performed their studies in a Japanese laboratory, the animals were kept squeezed in small cages for 8 h per day for 12 weeks during their ‘exposure’ from a mobile phone glued to the outside of the cage, under the rabbits’ scrota,” Professor Lerchl wrote.
“The mobile phones were set to the stand-by mode and thus did not produce any RF-EMF—there was no exposure! Still, the ‘exposed’ animals reacted with dramatic and sudden drops in sperm counts, sperm motility and seminal fructose levels.”
Professor Lechl recommended that experiments involving mobile phones should be set up with the help of scientists who have a detailed knowledge in biophysics, physics and electromagnetic theory.

“Only when scientists from all relevant disciplines work together, can reliable exposure conditions be achieved and proper risk analyses be performed,” Professor Lerchl concluded.
