I found this morsel on this link http://www.news24.com/News24/Technology/News/0,,2-13-1443_2432710,00.html

Here is an excerpt:

...A Japanese zoo puzzled by its lack of success in getting two polar bears to mate has discovered the reason - both are female. ...

I don't know much about the polar bear anatomy but certain things should be easy to check before you buy it (what would our Latin friends say...Caveat Emptor).
My question is, how hard is it to check a bear's gender?

Well, here's your problem...

Fox News: Study: Polar Bear Genitals Are Shrinking (http://www.foxnews.com/story/0,2933,210444,00.html) (August 2006)


The genitals of polar bears in eastern Greenland are apparently dwindling in size due to industrial pollutants, a new study finds.

Scientists report that this shrinkage could, in the worst-case scenario, endanger polar bears on Greenland and elsewhere by spoiling their love lives and causing their numbers to peter out.

Heh. Peter out.

Maybe it's the cold water.

Ok... how do industrial pollutants shrink genitalia?


Does this imply that the happy pill emails in everyones spambox may not be a scam after-all?

They're xenohormones. That is, non-polar bear produced chemicals which mimic hormones indiginous to a polar bear.

As for sex determination, a simple blood test (http://en.wikipedia.org/wiki/XY_sex-determination_system)works wonders.

I hope this is only limited to the polar bears.

Nope. Industrial pollutants are believed to account for a significant number xenohormetic chemicals which either mimic or block natural hormones. Other chemicals activate or suppress certain genetic actions. The results can appear as shrunken genitals, extra body parts, changes in metabolism, rates of reproduction, and the incidence and aggressiveness of various diseases, including cancer. Amphibians seem to be more heavily affected than other animals, as they live in a sea of agricultural and industrial runoff.
