It's almost impossible to know but there is probably not a lot. WHAT! Why do you want to know?
Master Chief is most definitely male. In the games, his voice is clearly male, and he is always referred to as male. In addition, the official backstory has him being a boy named "John" prior to him being selected to become a Spartan. Master Chief is a rank not a name, in the halo trilogy the main character is a spartan by the name of John-117 who is a male, but there are female master chiefs.
