> So a man won a boxing match with women

This should be stated hypothetically, because it hasn't happened (at least, not in any official, regulated match).

Has happened multiple times. Lastly in the Olympics. The evidence strongly suggests Imane Khelif is of male sex. Maybe most notable (though not boxing), 800m finals for women in 2016, gold, silver and bronze went to athletes of male sex.
