Comments on message lowered sperm quality

From Alfonso Balmori:
Very probably, like you say, the bisphenol-A is acting in the
deterioration of the quality of the sperm in human for several
decades. However the more abrupt deterioration of the quality of the
sperm has taken place in the last years: In Spain more than a third
(36%) of the procedures of artificial fecundation is for masculine
cause , of low seminal quality. The percentage went up five points
among the years 2003 and 2004, the last of that the Spanish Society of
Fertility (SEF) has figures. It seems that this is related (Besides
the bisphenol) also with an intensive use of the mobiles (Much higher
in the last years).
See the main studies in this respect:

"Our data suggest a decreased motility of rapid progressive
spermatozoa caused by electromagnetic waves of GSM- mobile phones.
These findings may have an impact in counselling subfertile men."

on male germ cell development, a significant genotoxic effect on
epididymal spermatozoa is evident and deserves further investigation"

the sperm count, motility, viability, and normal morphology. The
decrease in sperm parameters was dependent on the duration of daily
exposure to cell phones and independent of the initial semen quality."

"In the analysis of the effect of GSM equipment on the semen it was
noted that an increase in the percentage of sperm cells of abnormal
morphology is associated with the duration of exposure to the waves
emitted by the GSM phone. It was also confirmed that a decrease in the
percentage of sperm cells in vital progressing motility in the semen
is correlated with the frequency of using mobile phones."
