Mixed-Gender and Single-Sex Spaces: The Debate Over Places Reserved for Men and Women

Mixed-gender settings for women and men are often presented as a self-evident principle. Yet the issue of single-sex spaces remains sensitive: changing rooms, youth organisations, sports activities, friendship groups, discussion groups, and workplaces do not all serve the same purpose.

One critical perspective argues that the widespread adoption of mixed-gender settings has weakened certain traditionally male environments. It calls for the possibility of recreating spaces reserved for men, while noting that some women also support maintaining certain exclusively female spaces. Conversely, advocates of mixed-gender settings stress the importance of equal access and reject the idea of making sex-based separation a general rule.

Why have mixed-gender settings become controversial?

The debate is not only about the presence of men and women in the same place. It also concerns the purpose of the space in question: is it intended for studying, working, playing sport, receiving care, changing clothes, seeking protection, or building social ties?

Critics of systematic mixed-gender settings believe that opening all previously male spaces in the name of equality did not always take account of the specific social needs of boys and men. In their view, this shift has removed settings in which men could meet without the social pressure associated with courtship, competition, or women’s gaze.

From this perspective, single-sex spaces would not necessarily reflect a desire to exclude, but rather a way of preserving certain relational contexts. This position does not automatically entail rejecting all mixed-gender settings: its supporters instead argue for balance and for the coexistence of mixed and reserved spaces.

Women’s spaces and disagreements over access

Changing rooms, sports competitions, and certain activist spaces account for a significant share of the tensions. Feminists who describe themselves as critical of transgender policies argue that spaces reserved for women should remain based on sex. They raise concerns in particular about privacy, safety, and fairness in sport.

These positions conflict with those of activists and organisations that support the inclusion of transgender people in spaces corresponding to their gender identity. The disagreement is therefore profound: it concerns both the criteria for access to certain places and the very definition of what constitutes a women’s space.

Some commentators see a contradiction in this conflict: movements that long supported opening male spaces to women would now be confronted with demands to open female spaces to other groups. This interpretation is contested by those who distinguish between situations according to their context, the rights involved, and the rules specific to each institution.

Youth organisations: the example of the Boy Scouts of America

Youth organisations are frequently cited in discussions about single-sex spaces. The Boy Scouts of America, founded in 1910, have welcomed more than 100 million young Americans, according to figures cited in the debate. Their mission included passing on camaraderie, solidarity, self-reliance, and courage to boys aged 5 to 21.

In 2017, the National Organization for Women supported the idea of allowing girls to join the organisation. From 2018 onward, girls were indeed able to join Scout troops. The organisation also changed its name and its use of the term “Scout.”

For opponents of this change, the episode illustrates one-way openness, since the Girl Scouts are not presented as having opened their ranks to boys. For supporters of girls’ access to the Boy Scouts, the issue is instead about allowing young people who wish to do so to benefit from the same activities and opportunities for involvement.

Mixed-gender settings, performance, and competence: claims to examine

The issue of mixed-gender settings also arises in the military and the workplace. Critical arguments cite comparisons between mixed-sex and male military units, notably among the U.S. Marines and the Israeli Caracal Battalion. They argue that mixed-sex units are less physically capable, less resilient, or more prone to injuries.

These points are used to argue that certain environments, particularly those involving extremely high physical demands, should be organised with average differences between the sexes in mind. However, the references cited in this debate are not, on their own, sufficient to establish a general rule for all armed forces, all missions, or all organisations.

When it comes to office work, the assessment presented is more nuanced: several studies are mentioned, with differing results regarding the relationship between sex diversity and productivity. Some reportedly find a positive effect, while others find no observable effect. Above all, the debate highlights that a mixed-gender policy alone cannot determine levels of competence, cooperation, or well-being at work.

Reducing the difficulties of a profession to its feminisation or masculinisation therefore remains a political interpretation, rather than a conclusion established by the examples cited alone. Recruitment quality, training, organisation, assigned duties, and working conditions may also influence outcomes.

Male social bonding at the heart of the debate

The central argument in favour of male spaces concerns friendship among men. Richard Reeves, an American researcher described as a specialist in the condition of men in the West and president of the American Institute for Boys and Men, believes that male institutions and organisations should be viewed more favourably in light of rising loneliness, suicide, and mental health problems among men.

According to the analysis relayed in this debate, men are more likely to form relationships through a shared activity: sport, games, DIY projects, car repair, or other hobbies. The group then provides a practical setting for getting to know one another gradually.

Supporters of single-sex spaces argue that the dynamic of a group of men can change when a woman joins it, particularly if romantic competition emerges. This claim describes a frequently cited social experience, but it does not mean that mixed-gender groups necessarily prevent lasting friendships. Rather, it highlights the fact that social relationships may follow different patterns depending on the people and contexts involved.

Should spaces reserved for men be recreated?

The call for exclusively male spaces rests on the idea that men need places where they can build connections, support one another, and develop a collective identity without being immediately suspected of exclusion or hostility toward women. It also reflects a broader concern about male isolation.

Nevertheless, this demand raises an essential question: how can chosen spaces for social bonding be preserved without turning separation into a rigid principle? The answer depends on the type of space involved. A changing room, a support activity, a voluntary association, or a professional setting do not involve the same rights, obligations, or practical consequences.

The debate over mixed-gender settings cannot therefore be reduced to a simple opposition between progress and regression. It brings together several priorities: equal access, freedom of association, protection of privacy, social needs, and the requirements of certain activities. Recognising this complexity helps avoid slogans and makes it possible to examine the purpose of each space on a case-by-case basis.

Frequently asked questions about single-sex spaces

Is a single-sex space necessarily discriminatory?

Not necessarily. Everything depends on its purpose, how it operates, and the context. A discussion group, a changing room, or a voluntary association raises different issues from employment, a public service, or training.

Why do some men ask for male spaces?

They point to the need to build friendships, share activities, and overcome isolation. They believe that certain bonds are more easily formed in male-only settings.

Do mixed-gender settings prevent cooperation between men and women?

No. The debate mainly challenges the idea of applying mixed-gender settings indiscriminately to every space. Even among those who support single-sex spaces, some acknowledge that mixed-gender settings may be desirable in many areas.
