Sterility and politeness is variable, but I also work in that industry and have yet to encounter a situation where the banter resembles that of a largely risk free but comparably male environment like, say a sports ground or pub lunch with friends I've known since we were kids.

Which is a good thing really, because I wouldn't want to think that people were actually determining fitness to be trusted with a soldering iron or embedded systems design based on their witty comebacks or tolerance for jokes about their wife.
