Re: Sperm counts and industrial pollution



most interesting!

the math would have passed atmospherically over 99.9% of the viewers. Mmmm
selective memory -- I remember his calculating in his head the number of
combinations of an enigma code, but not the injections (probably too
unpleasant!)

about the cat. I thought they were driven by pheromones, elephants certainly
are (they sniff the cow's urine). OTOH maybe they just know it's a waste of
time if the urine doesn't smell of the hormone or whatever -- they're supposed
to be very smart.

P.s. A BBC series "Danger UXB" was based on a bomb disposal commander who's
love was the wife (fiancée?) of Touring.

His scientific advisor was her Father and also worked at Bletchley. One
interesting technique was to use liq. N2 to lower the batt.V to inactivate the
fuse.

Actually testosterone concentration is not as important as most people
think. Viagra does nothing for testosterone, but reputedly gives good
results. We have a 12 year old male cat that was neutered when young, but
after he started trying to mate with his littermate sister. A couple of
years ago he started getting randy and has erections. He doesn't quite know
how to finish, but he is good at starting. The female that he tries to mate
with has been neutered also so she is not receptive. Testosterone is
probably necessary for conception, but I think I recall that nitrous oxide
is the chemical which is necessary for physical performance. The cat has
zero sperm count, but can purrform. I talked to a vet who says that this is
not unusual.

I also recall that hormone injections while they can have significant
physical effects may not necessarily change performance. If anyone has seen
"Breaking the Code" about Alan Touring played by Derek Jacoby, you will
recall that the female hormone injections he was given did not have an
effect on his homosexual appetites. It is a good movie, but I was
disappointed that it did not cover his math. activities more. Actually
testosterone (and heredity) may have more effect on other things such as
body hair than on performance. This evidence comes from a pair of identical
twins one of whom was institutionalized and castrated for a mental disease.
The normal twin lost all of his hair, but the other one did not. As an
experiment the doctors gave the institutionalized twin 1 shot of
testosterone. He shortly became as bald as his brother.

and I thought (male) sexual performance was more related to
general health and
concentration of testosterone! (and not sperm count)

bc whose performance is considerably less than when we was half his age.

P.s. Is my sperm count reduced also?

So if I understand your reportage of Professor Hammond's conclusion;
it is that the well-proven wastage of human sex hormones and
their analogs
into the water supply has yet to be definitively linked to
changes in sexual
performance in that half of the human population known to be acutely
sensitive to environmental uptake of female sex hormone?

Yes, quite!
