It's more than just circumcision in Muslim countries. Sharia law places huge obligations on men. Women are viewed as sort of half-way children, not fully competent to make their own decisions or be held responsible for their own actions. What that means in practice is that you are responsible for your wife's, mother's, and adult daughters' behavior, and might be punished if they act out or break the law. You also face severe social censure and even in some places legal consequences if you don't provide for them financially.
