Human Sperm In Dramatic Decline Scientists Warn
By Aaron Derfel Montreal Gazette
Scientists from around the world are alarmed by a
dramatic increase in genetically damaged human sperm -
a trend that is not only causing infertility in men,
but also childhood cancers in the offspring of those
who can reproduce.
It's now estimated that up to 85 per cent of the
sperm produced by a healthy male is DNA-damaged, a
leading authority on the subject revealed yesterday at
an international conference being held in Montreal.
"That's very unusual," said John Aitken, head of
biological sciences at the University of Newcastle in
"If you were to take a rat or a mouse or a rabbit,
usually more than 80 per cent of their sperm would be
For the last 20 years, scientists have known about
declining sperm counts. But researchers are now
learning that the quality of human sperm is steadily
eroding, and might be causing birth defects as well
as brain cancer and leukemia in children.
Abnormal sperm is also being blamed for a global
increase in testicular cancer - a disease that strikes
men in their 30s. Scientists believe that when a
DNA-damaged sperm fertilizes a woman's egg, it can
trigger a mutation of a key gene in the embryo.
And even if men today can reproduce, their damaged
sperm might lead to infertility in their male progeny,
Aitken suggested. "You're likely to see lots of
diseases that are related to poorer semen quality."
Scientists suspect a wide range of environmental
causes for the abnormal sperm - from exposure to
pesticides and heavy metals to electromagnetic
"We're all exposed to 10 times more electromagnetic
radiation than our forefathers," Aitken said. "It's
all the electrical appliances we use, including
There is a consensus in the scientific community
that men who smoke cause damage to their sperm, and
that this might be responsible for childhood cancers.
"If you are a man and you smoke, your semen profile
won't be obviously affected," Aitken said. "You'll
still have lots of sperm swimming around and you'll be
fertile. But the DNA in your sperm
nucleus will be fragmented."
The average ejaculate of human sperm contains 80
million spermatazoa, each genetically programmed to
fertilize a woman's egg. Scientists examining human
sperm have discovered that not only are sperm counts
the decline, but that the vast majority of sperm is
sluggish, poorly structured, their DNA fragmented and
that they generate a lot of cellular waste called free
"Generally speaking, everything is bad with the
sperm," Aitken said.
Fortunately for most couples, it's the undamaged
or least damaged sperm that tends to fertilize the
As a result of increasing male infertility,
scientists have developed a new technique to help
couples conceive. It's called Intra-Cytoplasmic
Sperm Injection (ICSI). In the lab, a technologist
will take from the would-be father a single sperm, or
even a cell that is on its way to becoming a sperm,
and fertilize it in the test tube with the woman's
egg. The resulting embryo is then transferred to the
Dr. Keith Jarvi, of the University of Toronto-Mount
Sinai Hospital, said the ICSI technique has
revolutionized the treatment of male infertility. But
he wondered about the health outcomes of the ICSI
That human sperm is of poorer quality than that of
other mammals is not surprising. The human species is
the only one that wears clothes, and healthy sperm
need to be kept a couple of degrees cooler than the
full body temperature. But clothing alone is not

MANIFESTO FOR PR. BANDAZHEVSKY'S RELEASE AND
FREEDOM OF RESEARCH
Pr. Yury Bandazhevsky is currently imprisoned
in Minsk, Belarus since
June 2001. As a Doctor and an Expert on radiation
exposure caused by the
Chernobyl accident he was appointed in 1990 as
Rector of the Gomel Medical
institute. Gomel has been the hardest hit area by
nuclear releases. From
1990 to 1999, along with his wife Galina, also a
Doctor, Pr. Bandazhevsky
studied damages caused by Caesium 137: heart
diseases, cataracts, early
aging, etc.. He has discovered a measurable
relationship between nuclear
doses and various symptoms. In 1999, he published
his results at a time
when many people wanted to turn a blind eye to the
problems and wish to send
Belarus inhabitants back to the lands that are
still contaminated. Before his
arrest in July 1999 he had written a report
critical of the Belarus Government
official research conducted with international
funds regarding Chernobyl
after effects. Pr. Bandazhevsky was arrested
shortly after the issuance of
this report on the basis of a Presidential Decree
" for the Combat of
In 2001, he stood accused of having received
money from students
seeking admission to Gomel Medical Institute.
After a trial held before a
Military Tribunal he was sentenced to eight years
witnesses who attended the trial have noted at
least 8 infringements of the
Belarussian Criminal Code and the main prosecution
witness had retracted his
statement against Pr. Bandazhevsky. Pr.
Bandazhevsky is currently jailed in
a penal colony with harsh conditions tantamount to
But we think that the right to a fair trial
is not the only one to have
been thwarted. Beside people's opinions about
things nuclear, what is at stake is
the RIGHT TO KNOW THE TRUTH, the right to conduct
research and the scientist's
right to communicate data. Also the right for
people to know it without
interference that is politically or economically
THE INDEPENDENCE OF ALL RESEARCH in the
services of Humanity is as
important a principle as the independence of
Justice. Pr. Bandazhevsky's
imprisonment flouts both these principles.
Therefore, we, the undersigned,
ask for the immediate and unconditional release
of Pr. Bandazhevsky in
order that he can carry on his research without
interference at his
We suggest that all scientists, researchers,
scholars and citizens
stand for these principles:
- Sign this manifesto for freedom of research
and Pr. Bandazhevsky's
unconditional and immediate release.
- But also to have Pr. Bandazhevsky appointed as
a Best Man (or Honourable
Citizen) of their cities, such as Paris and
- Or have him appointed as Doctor Honoris
Causa in their universities
We wish to publish this Manifesto in a large
newspaper and send it to the
Belarus Government. Please sign it and pass it
to all parties interested in justice, freedom of
speech, freedom to conduct objective research and
human rights asking them to sign it, too. Your
help is greatly appreciated and will go a long way
in helping to free Dr. Bandazhevsky and promote
accurate research and publication of the radiation
induced effects of Chernobyl on humanity.

Sea birds drop radioactivity on land
19:00 02 January 03
Droppings from seabirds could be introducing radioactive isotopes into the food chain. That is the conclusion of researchers who found high levels of radioactivity in droppings and plants on an island close to the Arctic.
If tests confirm that the guano is bringing radioactivity ashore, it will need to be factored into pollution assessments that gauge radiation risks to human health and ecosystems. The risk is probably low at temperate latitudes, but could be much greater in the fragile wastes of the Arctic. There, guano is a major source of nutrients for plants, which are then eaten by animals.
Radioactive material gets into the oceans from natural geological processes on the sea floor, but radioactive isotopes from human nuclear activity can add to this. In the Arctic, radioactive material has been dumped in the Kara Sea to the east of the Barents Sea.
And radioactive material from nuclear accidents such as the 1986 Chernobyl disaster has reached the seas, along with particles from atmospheric tests of nuclear weapons.
The evidence that bird droppings are bringing radioactivity ashore comes from Mark Dowdall and his team at the Norwegian Radiation Protection Authority in Tromsø. They spent two years between 2000 and 2002 collecting soil, vegetation and guano samples from a remote coastal inlet called Kongsfjord on the Arctic archipelago of Svalbard, about halfway between the northern tip of Norway and the North Pole.
The samples of bird droppings were from vast piles produced by two colonies of seabirds supporting kittiwakes, puffins and fulmars. Tests showed the guano contained 10 times the concentration of radioactive isotopes found at other sites on the island.
The researchers found unusually high concentrations of the natural radioisotopes uranium-238 and radium-226, which decay to form more hazardous isotopes. But they also found high concentrations of the isotope caesium-137, which does not occur naturally. Dowdall suspects this is from the fallout of atmospheric nuclear tests carried out decades ago.
Tests on vegetation growing near the guano also revealed high concentrations of radioactive material. "It means that low levels in the Arctic environment don't stay low, they become concentrated," he says.
Fish and crustaceans
Dowdall believes the birds eat contaminated fish and crustaceans, and the radioactive material is then concentrated in their faeces. The extra nutrients the droppings provide encourage plants to grow, and the plants take up and concentrate the radioactive material.
This poses a problem, because plants make up the bulk of the diet of many animals, especially that of indigenous reindeer. "We're talking about a very vulnerable environment, and when reindeer eat the [contaminated] vegetation, it's in the food chain," says Dowdall.
Environmental researchers are intrigued by the finding. "I don't think people have looked at this particular pathway before," says Scott Fowler at the International Atomic Energy Authority's Marine Environmental Lab in Monaco.
However, in 1999, pigeons roosting in contaminated buildings on the site of British Nuclear Fuels' Sellafield reprocessing complex in Cumbria were found to contain 40 times the European Union's safe limit of caesium-137.

Ok theoryprocess, enough with the flooding. It isn't helping you any. And why don't you read your own link - the one titled "Chernobyl: Ten Years On Radiological and Health Impact." It confirms what I said about the [LACK OF] severetiy of the accident. 38 deaths from acute (immediate) radiation sickness (several other people died in the accident, but they were killed by the fire) and a statistically significant increase in only ONE type of cancer in the immediate area of the accident (several hundred cases of a curable form of thyroid cancer).
Now: could you PLEASE tell me how you can think that is worse than the 70,000 people who are killed by air pollution in the US EVERY YEAR.
With the radio tower thing, I'm also getting a much clearer picture of where you are coming from - you're a "dark ages" environmentalist. Someone who is anti-technology in general. Well, my friend, the first place to start is always with yourself - you posted all those floods with a computer. And [gasp] it uses electricity. There are several "dark ages" environmentalists who I have heard of who have gotten rid of all of their technology and gone to live in national parks. Those at least I respect - they aren't hypocrites.

This thread did have a point before you took it upon yourself to derail it.

Causing premature involuntary death is homicide whether
its some 200,000 a year from routine care in hospitals
Ralph Nader cites....or any other cause. But to say
Chernobyl only killed 38 people and to minimize the
worst industrial catastrophe in human history is like
saying the Holocaust never happened ! One Chernobyl
should have been enough.
|Nov21-03, 12:00 AM||#44|
But there has only been one Chernobyl, and 70,000 die each year from hacking death due to coal plants. Chernobyl happened once, killing far less than 70K per year. Which is the greater evil?!?

In any case, your answer is insufficient. Feel free to explain yourself and answer the question I posed, but further rants will be deleted.
And congratulations - in the two months I have been a mentor, your post was the first I have felt the need to edit.
Also, the last article you posted sounds complicated and technical enough to fool people who don't read it closely enough (thats probably why it is made to sound so complicated and technical), but it contains glaring errors in the assumptions and calculations. I would hope though that most lay people picked up on the fact that the title doesn't match the later statements - 1.2 vs 1.3 billion (overall casualties).
Also using the rate of 10 million and doing a reality check on how it relates to the 1.2 billion number brings up a glaring mismatch, seeing as how nuclear power/weapons have only been around for about 50 years. If the injury/death rate scaled linearly (it wouldn't - it would scale geometrically, reducing the total further) and the earth's population doubled since 1950, that would equal a total of 125 million casualties. Her own calculations don't match each other by an order of magnitude.
Further, such numbers are so high we would see them - clustered around nuclear power plants. The assumption of a uniform exposure of the entire earths population besides being preposterous allows her to ignore the fact that there is no statistically relevant increase in cancers in the vicinity of nuclear power plants.

Not technical enough...or too technical...here is a
good source of material that the layman can understand
but no doubt you will find some reason to dismiss it.
It is very rare for scientists to get enough funding to
do proper 'independent' studies.
EDITED by enigma
I wasn't kidding. No more links, no more articles. Not until you answer this:
A guaranteed mortality rate of 70,000 per year plus a dramatic increase in asthma and other breathing related illnesses.
How is the first one worse?
|Nov21-03, 12:49 PM||#47|
I hope this answers your question. I think death by radiation
is worse [BECAUSE RADIATION IS INVISABLE, ODERLESS AND HAPPENS
WITHOUT INITIAL SENSATION] by the time a victim gets cancer 20
years more or less...it is impossible to prove a direct cause
and effect. It may take hundreds of years of studies to show
good evidence...by that time mankind will be extinct.

While it's comendable to be concerned about the terribly high rate of respiratoy disease due to air pollution in the U.S., I'm not sure beating theroyprocess up over it is quite fair. It's illogical to say that to be anti-nuke is to be pro athsma. Were you guys equally insenced when the Bush administration gutted the Clean Air Act? Are you just as concerned with the problems many native american peoples are having with uranium mining ?
|Nov21-03, 03:57 PM||#50|
As far as the Clean Air Act goes, we should immediately do some more sweeping things such as require MASSIVE reductions in emissions by coal plants. Such things are possible, but expensive. And I think expensive is good - it will help the general public see the issue in terms they care more about since clearly people don't care enough about air pollution alone. The same goes for blackouts - blackouts are good because they show people the importance of making sound energy policy decisions.
The US is a "squeaky wheel" democracy. People only care about the issues that they percieve to be doing them immediate harm. Coal power isn't even on the radar for most people.
|Nov21-03, 04:01 PM||#51|
There are several countrys with a very good energetic network like France or the country i live - Portugal - and our energetic resources are quite different, where France energetic resources are around 80% supplied by nuclear plants, while Portugal doesnīt have a nuclear plant, my point with this is that just because blackouts happen that doesnīt implie that the solution is to increase nuclear powers, an investment in the energetic network supply would do the work in the US (and this has nothing to do with the energetic needs of each country, itīs just a matter of organisation on the network supply).
Iīm not saying the political climate would never change, but having in mind that itīs all about money, itīs very hard to happen, at least serious investments and dramatic changes would not happen, and considering this facts on how the New York blackout could have been prevented is just to say there isnīt a linear relation between the energetic production and the blackouts.
