An aspect of this problem is that society not only teaches people how to behave, but defines expected behavior. If a man defy those expectations and do seek help at a psychiatrist, a documented problem is that he won't be taken serious. Male patients get often too little or no medical support, while female patients suffer from over medication and forced hospitalization.
Beyond this, if knowledge is leaked that the man is seeking help, he will lose respect in the eyes of his peers, likely making any existing problems worse. Also, there is the issue of ones psychological health being used against them (such as some people wanting to restrict one's job or rights based on their diagnosed mental health).
