Is meditation good for men?

Yes, and the benefits are not gender-specific: attention training and nervous system regulation work the same way in everybody. The part that is worth adapting is the entry point rather than the practice. Men more often arrive with a single broad word for what is wrong, usually “stressed”, and a practice chosen for that word rather than the state underneath it tends to miss. Spend ninety seconds working out whether the state is hot or cold, whether it is pointed at something, and what would have to change for it to lift. Then choose.
