Lack of chemistry

The expression 'hung like a stallion' must not apply to polar bears. From AP-

TOKYO -- Puzzled Japanese zookeepers have cleared up a mystery over a lack of chemistry between a couple of polar bears as both turn out to be female, a Japanese zoo said Wednesday. Tsuyoshi, a four-year-old "male" polar bear, and his 11-year-old female partner, Kurumi, have been living together since June at the Kushiro Municipal Zoo in Hokkaido, northern Japan.

But much to the frustration and puzzlement of zookeepers, the bear couple, on a breeding mission, showed no signs of chemistry, and Tsuyoshi has never gone into rut even during "his" mating period.

"Observing his behaviors, we got suspicious as to whether Tsuyoshi was really a male," the zoo said in a statement.

The zoo put Tsuyoshi under an anesthetic earlier in the month for a gender checkup, and learned he was a she.

Why wasn't this test done before they tried to mate the two polar bears? Was this zoo government run or subsidized? That may explain things.

Note- I know where the city of Kushiro is in Japan. Part of my latest webfiction story was set in the city.
