Physical abuse is another story. In our society we think of women as the victims and men as the aggressors in physical abuse. But that is not true. Equally as many, if not more, men are assaulted by their girlfriends or wives as vice versa. This runs counter to official documentation of female abuse against men.
Less men report abuse.
They are ashamed to report being abused by women. Health care and law enforcement professionals are more likely to accept alternative explanations of abuse from a man. They will believe other reasons for the presence of bruises and other signs of injury. Our justice system sometimes takes the word of the woman above the word of the man in abuse cases. It is just more believable that the aggressor was the man, not the woman.
