I know that I'm sounding like a Frasier-geek but I ca't help remembering the episode where Niles and Daphne are trying to conceive and Niles' pants are beeping because his "TestiCool 2000", which is keeping his "nether regions" at a constant 96 degrees, needs to be recharged. Tight jeans have been blamed for a lot of problems and quirks in the field of male fertiity owing to their keeping "the boys" too close to the body and thus at a higher temperature than they were designed to be held at.

Another anecdotal bit of biz is the theory that military fighter pilots tend to father more girls than boys statistically...this is attributed to their throwing more "g's" than the average schmoe and that this has an effect on the genes that they're passing on...boo-yah!

Go figger...

Best
