Men's spaces are separate social and cultural spaces, roles and norms available to men in some non-westernized societies. It is the membership of these spaces that determines a male's manhood, while failing to get a membership of this space amounts to being denied manhood, and to be liable to queerhood, i.e. to be counted as a 'third gender' or a non-man male.
In non-westernized cultures[specify], most[dubious ] traditional spaces[clarification needed] are divided into men's spaces, women's spaces  and third gender spaces.[not in citation given] The entry or participation of women in these men's spaces is highly restricted. Entry of third genderered persons into men's spaces is also regulated, although with more freedom than women to partake in these spaces.[not in citation given]
History of men's spaces
In the early days of human civilization, as proven by several indigenous and aboriginal tribes[dubious ][specify], boys, along with other children, lived in women's spaces till they reached puberty, after which they generally had to undergo 'manhood tests' or 'rites of passage into manhood' in order to be initiated into men's spaces.
The manhood tests became more and more torturous with time during which men were expected not to show the slightest sign of pain or sigh[specify][which cultures? gross overgeneralisation]. Boys who failed these tests were denied membership of men's spaces, which amounted to denying manhood and being emasculated, and were isolated as one of the third genders, deprived of social rights and privileges available to 'men.' This was a fate worse than death for masculine gendered males.
The feminine gendered males, i.e. the third genders were in some tribes[specify] exempt from manhood tests and were raised as third genders from early childhood, when they showed what is today known as "Gender incongruent behaviour."
In what are considered modern civilizations[specify], it is still of great importance to be counted as one of the men. It can even be a matter of life and death for masculine gendered males. - and to be isolated as a 'third gender' remains severely stigmatizing for masculine gendered males.
Effects of westernization on men's spaces
Some  in the Western World think men's spaces are discriminatory toward the rights of women, and therefore fit for abolition. This is due to an overlap of previously all-male spaces and what was considered the "old boy network" - channels of social and financial upward mobility that were conducted in all-male spaces. All-female spaces are generally viewed as beneficial for women, focusing on providing access to safety as opposed to gender-segregated access to opportunities.
There are few exclusively-male spaces in contemporary western culture, and even such former strongholds of men's space as military and sports environments have become more gender-neutral.

In my own case, the fact that, as a foreigner, I was already outside the cultural norm combined with my "passion for the song" (reinforced by the distances I had traveled) to make it less problematic than might have been expected for me to move in men's spaces. I was also doubtless held to be pardonably naive as far as matters of honor were concerned.

Mathews, L.S.]; Quotation: "The male aboriginal, on attaining the age of puberty, reaches the most eventful period of his life. Hitherto his place has been amongst the women and children, but he now passes through a ceremony admitting him to a brotherhood whose secrets are inviolable and whose power is more dreaded than any Vehmgericht. Now filled with a sense of the dignity of manhood, he becomes entitled to greater privileges than previously enjoyed."

Gilmore (1987, 15) has pointed to the lack of male initiation ceremonies in the Mediterranean as a whole and the resulting ambiguity as to what marks the passage of a boy at puberty from the female-dominated domestic world to adult male society. The fact that it is usual for Corsican males to become properly integrated into the paghjella-singing tradition at the time of their passage from adolescence to adulthood, as signified by the breaking of the voice (Catinchi 1999, 51), suggests elements of a male rite of passage that, together with the function of male bonding already discussed, makes any female intrusion understandably inappropriate or at least discomforting.

Spriggs, October 6, 2003; Quotations: This is the (initiation) ritual, different from tribe to tribe, and almost non-existent for girls, which marks a boy's passage into manhood. These rituals affect the way boys are conditioned to value "manhood." ...Boys, in order to become men, have to prove that they are unafraid, and they can take pain "like a man." Only then can the boys see the sacred objects, learn the secrets of the clan, and history of the clan's great achievements...All of these activities create a bonding and a brotherhood of males, collectively shocked into manhood by pain and fear. The initiates form a bonding which lasts all their lives."

But as James Twitchell, professor of English and advertising at the University of Florida, wryly suggests in his latest book, Where Men Hide, the twenty-first century male--and in particular, the twenty-first century American male--is lonely, his impulse to "tribalize" with other men quashed by the demands of modern life. Not only are males--particularly young ones--difficult to find; the spaces they might be expected to inhabit have become progressively emptier. And so Twitchell asks the question: where have all the men and all-male spaces gone?
