A lot of people deal with fertility problems these days. In a lot of studies it’s shown that day to day exposure to radiation has influenced decreasing fertility in both men and women. But overall more research has been done on the fertility of men. In 2010 the European Science Foundaten published a report which stated that 1 of every 5 men are ‘less fertile’ and the quality and quantity of the sperm cells has been decreasing constantly – the last decennium alone it was about 20-30%.
A study done in 2008 of which the results have been published in the American Society for Reproductive Medicine said that men who use their cell-phone for about 4 hours a day have 25% less sperm cells compared to men who don’t use a cell-phone. Of the sperm they did have, 80% was deformed. The mobility (a measure for the swimming ability and a crucial factor in the conception) has reduced by a third.
Other studies gave similar results, such as the study done in 2011 by Queens University. 2100 Men were examined and the result was that there was a ‘significant difference’ between men that use a cell-phone and men that don’t. In addition this study showed that the concentration of luteinizing hormone, an important reproductive hormone in the brain that is secreted by men, was decreasing.
According to The New York Times and reputable researchers like Dr. Henry Lai of the University of Washington, indicates that about 70% of the non financed wireless-industry studies show that the everyday radiation has a bad biological impact. The biological effects can be ordered in 3 different categories: the cell growth, the DNA-replication and the neurological functions.
The impact on the cell growth went from a set delay of the cell growth and cell damage, to a disturbance of the cell adhesion (Aldinucci et al. 2003, Buemi et al. 2001, Pacini et al. 1999, Raylman et al. 1997, Linder-Aronson & Lindskog 1995).
On a genetic level deviations in the gene expression (Hirose et al. 2003, Hirai et al. 2002) and in the fetal development have mainly been established at the level of the cardiovascular system. Until today most studies have been done in a controlled laboratorium. It’s hard to say how this manifests on a scale of the population. It can take quite some years until the side-effects have been discovered (in addition, exposure to radiation in order of magnitude more than 15 years ago).
The fear is that small but overall scattered changes in the cellular and genetic processes in the early childhood will have an effect on the development, especially for children. The brain of children is constantly developing and their tissue absorbs relatively much radiation compared to adults.
A study done in 2010 by researchers of the UCLA on 29.000 children gave the result that on the age of 7 children have a 50% chance of behaviour problems when regularly exposed to cell-phone radiation in the uterus and in the early childhood. Possible behavioural problems were hyperactivity, attention disorders and social problems. An previous study on 13.000 Danish children gave similar results.
According to this study the risk for children getting behavioural problems is higher when the uterus was regularly exposed to cell-phone radiation when pregnant. The mechanisms behind this connection have not yet been clarified. It has been suggested that the radiation from cell-phones/laptops have a direct influence on the regulation of hormone secretion, which has an influence on the metabolism and the development of the brain.
