Do cell phones decrease male fertility? Researchers at the
Cleveland Clinic think so. According to Ashok
Agarwal, et. al., greater
use of cell phones is associated with decreased sprem count.
Other factors, such as sperm motility, are diminished as well.

an observational study.

OBJECTIVE: To investigate the effect of cell phone use on
markers of semen quality. DESIGN: Observational study. SETTING:
Infertility clinic. PATIENT(S): Three hundred sixty-one men undergoing
infertility evaluation were divided into four groups according to their
active cell phone use: group A: no use; group B: <2 h/day; group C:
2-4 h/day; and group D: >4 h/day. INTERVENTION(S): None. MAIN
OUTCOME MEASURE(S): Sperm parameters (volume, liquefaction time, pH,
viscosity, sperm count, motility, viability, and morphology).
RESULT(S): The comparisons of mean sperm count, motility, viability,
and normal morphology among four different cell phone user groups were
statistically significant. Mean sperm motility, viability, and normal
morphology were significantly different in cell phone user groups
within two sperm count groups. The laboratory values of the above four
sperm parameters decreased in all four cell phone user groups as the
duration of daily exposure to cell phones increased. CONCLUSION(S): Use
of cell phones decrease the semen quality in men by decreasing 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.
Obviously, this is a statistical association that might not mean
much. Still, it would be interesting to know if there is any
association with the hypothalamic hormone, GnRH, and/or the pituitary
hormones LH and FSH.
Probably it is not the cell phone itself; it is the ringtones.
Just to be safe, perhaps we shouldn’t be clipping the cell phones to
