If a woman does/says/wears/etc. something wrong (or a man just thinks she did), she can be publicly raped and then publicly executed. This happens for the tiniest infractions, such as looking at someone the "wrong" way, or burning the roast.
Women are not even accepted in Mansworld and are killed on sight if they ever venture in it. Reproduction is taken care of through technological means and female babies are automatically aborted.
Mansworld is a religious nation, based around the worship of a Straw Misogynist war god and his ideals.
A high mortality rate has led to a drastic reduction in the population and the people will die out if birth rates do not increase significantly, so the law punishes those who are not in the process of making babies. This obviously demands more from women than from men.
Although women in Mansworld are not seen in positions of power or significance, beating and raping them is severely frowned upon; aside from being required to fulfillcertain roles and ideals whether they want to or not, they are treated very well.
Women travel through with no ostensible trouble from the denizens of Mansworld.
This state is a form of Stepford Suburbia; a woman who does not conform to accepted standards of beauty, lifestyle, personality, aspirations, etc. (i.e. a Hollywood HomelyTsundere who wants to be a scientist rather than a housewife) is killed (or brainwashed) by her nearest male relative.
Female travelers are covertly kidnapped in the middle of the night and sold into prostitution or sexual slavery.
The men of Mansworld are all (hilariously sterotypical) homosexuals hell bent into making women's life an unbearable tribulation... Except their methods to pull it off aren't all that villanious nor destructive, so women just consider them a minor nuinsance at worst, and quite amusing (and kinda cute) at best.
The men of Mansworld still fear the possibility of catching cooties from their female counterparts, just as grade-school children do.
Inferior women are required to wear leggings with an unsightly crease down the front and a matching ceremonial leash around their necks at all times. A suit and tie in other words. As the superior gender the ruling men all wear far less restrictive floral dresses.
Zig Zagged: Depending on the king they have at any given time and how he feels women are to be treated, the society fluctuates between treating women as sub-human just because they are women, women are seen as inferior, but tolerated and not treated too badly, and women are seen as just as valuable and competent as men and treated accordingly.
Averted: The society in question is a society where men and women are seen as equally valuable and competent, and treated accordingly.
The writer is discussing a time and place where women have historically been (or still are) mistreated.
Lampshaded: "This place doesn't seem very female friendly..."
Invoked: Some man takes over (whether by military means, winning an election, or simply being born into the Royal Family), and seeks to create a Utopia where men are in charge.
Exploited: Bob moves to Mansworld so that he can be free to mistreat the women who "belong" to him as he's always wanted.
The laws (religious or secular or both) of that society specifically state that men and women are equal and are to be treated as such, and the society does just that.
A brave woman decides that enough is enough, and starts a revolution to depose Mansworld's retrograde ways. And when the dust has settled, and victory is attained, she (and her loyal comrades) decides to reform the society into one where men and women are treated as equal.
Discussed: "Why do they treat the women so badly? Because they're bad people, and because they're insecure little boys in men's bodies."
Mansworld was started by a bunch of straw misogynists, who believe mistreating and beating up women ensured the men would have a happy life. The abuse gets so bad that their women suddenly decide to mass-suicide themselves, leaving only men and boys in Mansworld.
The practices stemming from the lack of respect for women in Mansworld results in a heavily skewed gender ratio, whether from abuse, honour killings, female infanticide, or high female suicide rates. This results in a dire demographic crisis.
Mansworld is treated as a pariah nation for its abuses of women, and is unable to function as a nation because no one wants to work with it.
Reconstructed: The residents of Mansworld learn that women are a great asset to their society, and have much more to contribute than just sons and hot dinners. The society is reformed, and becomes a more egalitarian society, where men and women are seen as equally competent and valuable, and given the same rights and responsibilities.
Played For Drama: The story focuses on Alice, who has grown up in Mansworld and suffered a life of discrimination and abuse.
