For professional reason, I never changed my last name at work but hyphenated it on everything else. I am not really a big fan of hyphenation, but it as an established professional it made the most sense. If it wouldn't have created an issue for me at work (being known by my maiden name & working at the same place as hubby), I would have been just as content to take his name. As for the guys doing it, can't speak to that one, because I have no friends who have done it. I do know one guy who has a hyphenated last name, but it was given to him at birth, his mother's maiden name is his middle name.
