Men who smoke are less likely to make a
woman pregnant than nonsmokers, and the
more they smoke the worse their chances
are, a new study finds. Researchers from
the state university at buffalo school of
medicine say that male smokers experience
changes in their sperm that make
fertilization more difficult. The study
was presented last week at a conference of
the american society of reproductive
medicine. Cigarette smoking can also
affect male fertility: smoking reduces the
quality of semen. Men who smoke have a
lower sperm count than non-smokers, and
their semen contains a higher proportion
of malformed sperm. By-products of
nicotine present in semen of smokers have
been found to reduce the motility of
sperm. One study found that sperm damaged
by smoking may also result in more couples
having baby girls than boys. The
researchers suggest that the sperm cells
carrying the y chromosome are more
vulnerable to the toxins in cigarette
smoke.

A little random, but not a surprise at
all. But think of it this way, the
nonsmokers are probably healthier.
