Yes. Women have historically certainly been denied rights and oppressed in a number of ways but there are also numerous examples of men being the ones oppressed because of gender. The most basic way is the draft. At many times throughout history across cultures men have not been given a choice of whether they want to go off to fight in a war and have died in mass numbers as a result. Had they been born a woman they'd have been at home.

In a more modern example men have more trouble getting paternity rights than women do in cases of divorce. 

There was also a famous Supreme Court case argued by RBG that was a case of a man not receiving caretaker benefits because he was a man taking care of his elderly mother. That opened the door to many other gender based oppressive laws (mostly targeting women) to be removed. But that one was still unfair to men.

Adding on another one: men who want jobs taking care of young children are often met with suspicion that women never face even though both men and women can be abusive toward young children and both men and women can be loving caretakers of young children.
