I've known men and women who deny they have problems, but I think it's much more common for men. There are really two different issues, though. There are guys who deny they're depressed altogether, and then there are guys who know they're depressed but just don't want to talk about it. There's a book out there called I DONT WANT TO TALK ABOUT IT: OVERCOMING THE SECRET LEGACY OF MALE DEPRESSION. I've been meaning to read it for a while now.
