Previous research has suggested that Radio-frequency
electromagnetic radiation (RF-EMR) emitted by the devices can have a
detrimental effect on male fertility. Most of the global adult population own
mobile phones. This study strongly suggests that being exposed to
radio-frequency electromagnetic radiation from carrying mobiles in trouser
pockets negatively affects sperm quality.
TEST SAMPLE:
A team led by Dr Fiona Mathews, of Biosciences at the
University of Exeter, conducted a systematic review of the findings from ten
studies including 1,492 samples, with the aim of clarifying the potential role
of this environmental exposure.
Participants in the studies were from fertility clinics and
research centres, and sperm quality was measured in three different ways:
·
Motility
(the ability of sperm to move properly towards an egg)
·
Viability
(the proportion of sperm that were alive)
·
Concentration
(the number of sperm per unit of semen).
RESULTS OBTAINED:
In control groups, 50-85% of sperm have normal movement. The
researchers found this proportion fell by an average of 8 percentage points
when there was exposure to mobile phones. Similar effects were seen for sperm
viability. The effects on sperm concentration were less clear.
NEED ARISES:
Given the enormous scale of mobile phone use around the
world, the potential role of this environmental exposure needs to be clarified.
This could be particularly important for men already on the borderline of
infertility.
Further research is required to determine the full clinical
implications for the general population.
