Obese reproduction
April 11, 2012
A NEW study published in the
Archives of Internal Medicine has
found that obese men have 80%
higher odds of producing no sperm.
The meta-analysis study looked at
almost 10,000 men from
across the world, including Asia,
Europe, and North America.
The results found that a man who
is considered obese has about 42%
higher chance of having very low
sperm and more than an 80%
chance of having no sperm as
compared to a normal weight man.
In addition, the research also
uncovered evidence which suggested
that obese men have a decreased
chance of having a child even after
IVF, indicating that obesity not only
affects the number of sperm, but
the quality of sperm as well.
“Though it's long been known
that overweight women have a
harder time conceiving, this is the
first well-designed study that links
male obesity to low sperm
numbers,” said study co-author
Dr Alex Polotsky of University of
Colorado Advanced Reproductive
Medicine.
“We need more studies to really
prove that weight loss will result in
a higher chance of pregnancy, but it
makes sense that this would be the
case,” he added.
