I'm not sure what you mean by "not work for men". In Sweden parental leave is just a normal part of society for both partners and it works great (indeed I'd go so far and say that all of my male colleagues that have gone on parental leave have all looked forward to it). I think the main thing to make it work is just to have a society that values people being able to spend time with their children. If it is a normal everyday part of life where society supports it (for example financially) it works great.
