I just heard it on the news literally like 3 seconds ago. Heres an article:

If you're man thinking about having kids, you might want to cut back on your cell phone use.
That's the preliminary finding of a study done by The Cleveland Clinic,
which found statistically that men who used their cell phones the most
had poorer sperm quality than those who used them the least.
The lowest average sperm
counts seemed to be in men who had the most cell phone use (more than
four hours a day); those who didn’t use cell phones seemed to have the
highest. Although the sperm count appears to go down with increasing
cell phone use, the difference in numbers wasn't significant.
The findings, however, do not prove a link between cell phone use and semen quality, researcher Ashok Agarwal, PhD, said.
“This
is still very preliminary and I would not want these findings
misinterpreted as showing that cell phone use is a definite cause of
decreased [male] fertility,” he said. “There are still many unanswered
questions.”
About a billion people worldwide now use cell phones, and some projections suggest that within the next five years that number could double.
A
link between cell phone use and reduced sperm counts has been suggested
in several earlier studies, but none has been considered conclusive.
The new study included 364 men being evaluated for infertility between September 2004 and October 2005.
In
addition to undergoing tests to determine sperm quantity and quality,
the men answered questions about their cell phone habits.
Most
of the men had sperm counts that were well above the 20 million sperm
per milliliter level that is considered the lower limit of normal. The
more the men in the study used their phones, the lower their sperm
count tended to be.
The
average sperm count among men who said they did not use cell phones was
86 million per milliliter (mL), compared with 76 million/mL for men who
used cell phones less than two hours a day and 71 million/mL for men
who used cell phones two to four hours a day.
Men who reported using their cell phones more than four hours a day had the lowest average sperm counts — 66 million/mL.
Significant
downward trends were seen when other sperm-quality parameters were
measured, such as percentages of sperm swimming well, living and viable
sperm, and normal sperm shape.
Cell
phones are not the only modern conveniences suspected of influencing
sperm counts. At least one study has suggested that wearing disposable
diapers as a baby can influence adult fertility, and another proposed a
link between laptop use and sperm quality.
None
of these suspected environmental influences, however, has been proven
to influence male fertility, said Rebecca Sokol, MD, PhD, president of
the Society for Male Reproduction and Urology.
Her own research suggests a link between air pollution and declining sperm quality.
Sokol calls the cell phone study “provocative,” but far from conclusive.
“This
is an interesting observation that may lead to larger, more controlled
studies to see if the observation holds up,” Sokol said.
An infertility specialist at the University of Southern California's Keck School of Medicine, Sokol said there isn’t a lot she can tell patients when they ask about suspected environmental influences on male fertility.
“I
tell them what we know, which isn’t a lot,” she said. “We know that
high (scrotal) temperature is bad for sperm, and we think that smoking,
drinking, and marijuana use are probably bad. But we still have a lot
to learn.”
