Q: What are the disadvantages of being a female in a male-dominated CS/engineering university?
The other answers to this question are all spot-on and great. I will just add one more.
When a technical woman gets older, say around age 35, the younger technical men will gradually stop regarding her as a potential love/sex interest, and instead they will start thinking of her as their mother. You'll be expected to be all supportive and nurturing to them, to listen to all their problems and tell them that -- no matter what -- they are so talented.
