Are toxins in your home causing infertility? Posted: 12-04-07 21:40pm
Is there a link between infertility and
environmental toxins?
Although scientists and others speculate
that infertility can result from exposure
to any of a number of environmental
toxins, the evidence is scarce and
inconclusive, especially in women.
For example, researchers have shown that
average sperm density (number of sperm per
milliliter of semen) has declined
dramatically over the past 60 years all
over the world. It has been dropping
steadily at 1 to 3 million sperm per
milliliter per year, from more than 100
million sperm per milliliter in 1938 to
less than 70 million sperm per milliliter
in 1990. It is not exactly clear what has
caused the decline, but it may be at least
partially linked to exposure to various
environmental toxins. Importantly, many
scientists argue that it is not clear
whether reduced sperm density causes
infertility or not and that even though
sperm density has been on the decline, it
may not mean anything with regards to
infertility.
The link between environmental exposure
and infertility remains an important area
of scientific research.
At least 50 chemicals in widespread
industrial use have demonstrably negative
effects on reproductive function in
animals. Yet only four workplace health
hazards -- lead, ionizing radiation,
ethylene oxide, and dibromo chloropropane
(DBCP) -- are regulated in the United
States partly because of their effects on
human reproduction.
Exposure to possible reproductive hazards
occurs in four separate ways:
* at the workplace (e.g., industrial
byproducts)
* in the home (e.g., paint)
* through personal factors (e.g.,
cigarettes, alcohol)
* in the environment (e.g., pesticides)
With that said, did you know that Lysol is
a registered Pesticide?
According to the March of Dimes, one in
twelve children is born with a congenital
defect. Environmental factors, including
exposure to toxic chemicals, cause 7% to
11% of these defects. 60% of birth defects
have unknown causes, but toxic chemical
are suspected in those cases as well.
High levels of toxins have been found in
many women with endometriosis.
We know that many miscarriages happen
every year, and that, in many cases, a
miscarriage is the body's recognition of a
defect in the fetus. Could it be that
toxins are causing birth defects your body
is picking up on?
