'The Matter of Seggri' by Ursula K. Le Guin is a short story to tell that in Seggri, Le Guin sets up a society in which the status of men and women is switched, women are responsible for production, and men are concentrated in sex clubs to provide services for women. In addition, only women were allowed to have emotional contact with each other, and the relationship between men and women could not be more than physical.

In this short story, men still show physical and objective advantages over women in strength and other aspects. Their nights thus are spent in carnal satisfaction as often as they desire, and their days in a diversity of sports and games, notably a kind of wrestling, in which they throw each other through the air so that we marveled that they seemed never to take hurt, but rose up and returned to the combat with wonderful dexterity of hand and foot. (Le Guin, p. 387) However, such advantages are not constructed into social advantages due to the extremely low survival rate of men but shift the balance of social advantages to women. In limited space, this story le Guin ever-present emphasizes the social construction of the planet to readers: hemorrhagic, strength and rude on this planet have never been commendable of so-called masculine, but fragile and realistic representation of the so-called women cry, perceptual good jealous, etc., is a disdain for social lack of rationality. The embodiment of reason, which represents the nobleness of the human soul, is the physically weak woman. Rather than removing men, in works such as Delany’s Triton (1976), the notion of social manifestations of gender are multiple and diffused to the extent that they become meaningless, and all kinds of gender/sexual difference are celebrated. (Merrick, p.249)

The ironic effect is enhanced by Le Guin's clever thinking and subtle contrast: men are deprived of educational opportunities just like women in real life, and "can do nothing but compete and fight". Men are required to be strong in order to look like men. The fact that men have become a reproductive tool controlled by society also proves that pregnancy is not an innate weakness of women and that men's advantages have been selected as disadvantages by society when sperm is more valuable for survival. But probably not, because men who don’t win at things aren’t allowed to go to the fuckeries. Only the champions. (Le Guin, p.390) Le Guin in this undoubtedly shook the essentialist fundamental argument foundation, namely physiological determines the superiority of the male, she issued a sharp in the word games, the almost bitter mockery that biological strengths and weaknesses are worthless without survival choices, and society is what determines what is good and what is bad, The fragile connection between the physical base and the social construct is blown up in this intense irony. Le Guin directly confronts the question of socialized versus biological difference, as the human narrator, Genly Ai admits, 'it' extremely hard to separate the innate differences from the learned ones.' In this society, 'humanity' is defined as a commonly accessible and shared set of values, attributes, and behaviors tangibly separated from arbitrary and shifting notions of the self based only on a sexed embodiment. (Merrick, p.247)

The most valuable thing in The Matter of Seggri is that Le Guin does not give up her support for human freedom as a social constructionist while sharply attacking essentialism and conservative male thinking.  “I want to get married.” Her eyes widened. She brooded a bit, and finally ventured, “To a man.” “No. To a woman. I want a normal, ordinary marriage. I want to have a wife and be a wife.” (Le Guin, p.414)
