SEX HORMONES TAKE FORM AS GENDER CHANGES SHAPE
It wasn’t until the turn of the last century that scientists began to examine seriously the idea that chemical secretions regulated the body’s physiology. Although in the 1890s the British physiologist Edward Schafer interpreted the results of gonadectomy (the removal of either the testis or the ovary) in terms of nervous function, over the next few years, he and his students began to reevaluate.20 In 190^ Ernest Henry Starling, Schafer’s successor as Professor of Physiology at the University College in London, coined the word hormone (from the Greek ‘‘I excite or arouse’’). He defined hormones as chemicals that “have to be carried from the organ where they are produced to the organ which they affect, by means of the blood stream.’’21
British physiologists gave birth to and embraced the hormone concept during the years 190^ to 1908. Their scientific issue (especially the secretions
produced by the sex glands, the ovaries and testes) arrived during a period when the populace of the United States and many European nations had begun to reevaluate traditional constructions of gender and sexuality.22 New debates opened up over the rights of homosexuals and women—while what historians have called a ‘‘crisis in masculinity’’ developed in both Europe and the United States.23 At the same time, events such as the founding of the field of scientific sexology; Sigmund Freud’s early years, as he moved from theories of neurology to the invention of psychoanalytic psychiatry; and the insistence, especially in the United States, of an experimental approach to the biological sciences developed in the context of these gender struggles.24 The attempt to define and understand the role sex hormones played in human physiology was no exception. From the beginning, such research efforts both reflected and contributed to competing definitions of masculinity and femininity, thus helping to shape the implications of such definitions for the social and economic roles to be played by the men and women of the twentieth century.
What were some of the elements visible in the new debates about masculinity and femininity? The historian Chandak Sengoopta writes that turn-of – the-century Vienna experienced ‘‘a crisis of gender… a moment when the boundaries and norms of male and female shifted, disintegrated and seemed to intertwine.’’25 In Central Europe this crisis also took on racial overtones, as social commentators debated the Jewish Question, depicting Jewish men as both effeminate and as sexual predators.26 In this same period, the German physician and reformer Magnus Hirschfeld and his colleagues founded the Scientific-Humanitarian Committee, which repeatedly petitioned the Reichstag to repeal the national sodomy law.27 Male homosexuals, they argued, were natural sexual variants, not criminals. Women’s rights and the emergence of homosexuality were no less salient in England and the United States.28 Table 6.1 lists two decades of events that wove together the social movements of feminism and homosexual activism with the emergence of the scientific study of sex and the idea of sex hormones.
The Biopolitics of Feminism and Homosexuality At the turn of the century, social commentators tried to extract political lessons from scientific knowledge about human development.29 In 1903, for example, a Viennese philosophy student named Otto Weininger published an influential book entitled Sex and Character that drew on the ideas ofnineteenth – century embryology to develop a comprehensive theory of masculinity, femininity, and homosexuality. Weininger believed that even after their distinctive anatomies emerged, males and females each contained both male and female sex-determining substances (plasms) in their cells. The proportion of these

b. Geddes and Thomson 1893. This book provided a definitive account of biological variability in systems of sexual reproduction and accounted for the evolution of sex in terms that many still use today. The book focuses primarily on the nonhuman biological work, yet became a cornerstone for thinking about the evolution of sex in humans.
c. While ‘‘the sensational trial of Oscar Wilde in 1893 for homosexual conduct created wide public interest in sex inversion and called forth a considerable literature’’ (Aberle and Corner J933,p. 3), then as now scientific interest in female homosexuality lagged behind (Havelock Ellis’s work on homosexuality devoted no more than one-third ofits pages to lesbianism, which it linked to prostitution). But during the first two decades of the twentieth century, lesbianism nevertheless became a public issue.
d. [The original U. S. publication date for Ellis was 1901. I quote from a 1928 edition.] Ellis’s tomes on human sexuality set a high scientific standard for the period; he was dispassionate and nonjudgmental about the wide variation in human sexual behavior.

1913 British endocrinologist Walter Heape publishes Sex Antagonismik plasms differed from one individual to the next, thus explaining the wide range of masculinity and femininity observed among humans. Homosexual men had almost equal proportions of masculine and feminine plasms.30 In England, Edward Carpenter published similar ideas: ‘‘Nature, it might appear, in mixing elements which go to compose each individual, does not always keep her two groups of ingredients—which represent the sexes—properly apart. . . wisely, we must think—for if a severe distinction of elements were always maintained the two sexes would soon drift into far latitudes and absolutely cease to understand each other.’’31 Weininger thought that women’s drive for emancipation emanated from the masculine elements in their bodies. He linked this masculinity with lesbian desire, using talented women such as Sappho and Georges Sand to exemplify his claims. But even the most talented women still had a great deal of female plasm in their bodies, making full equality with men impossible. Thus built into this theory is the a priori assumption that all striving for public life, talent, and achievement by definition comes from masculine plasm. At best, women could achieve only partial manhood.32
In the United States, writers also described women’s desire to vote as a biological phenomenon. James Weir, writing in the magazine The American Naturalist, used evolutionary arguments. Primitive societies, he noted, were matriarchies. Giving women the right to vote and hold public office would bring about a return to matriarchy. Women have this atavistic desire to vote for a simple reason. Feminists are virtually all viragints—domineering, aggressive, and psychologically abnormal women. They are evolutionary throwbacks. Some have ‘‘the feelings and desires of a man,’’ but even the most masculine among them can function only by emotion, not logic. Weir saw ‘‘in the establishment of equal rights, the first step toward the abyss of immoral horrors so repugnant to our cultivated ethical tastes—the matriarchate.’’33
Of course not everyone, and especially not all scientists, opposed women’s emancipation. But the social models of gender both fed and emerged from two sources of nineteenth-century biology: the embryological and the evolutionary. The idea that the public sphere was by definition masculine lay so deep in this period’s metaphysical fabric that it did not seem surprising to argue that women who aspired to the Rights of Man had also, by definition, to be masculine.34 Whether female masculinity was an evolutionary throwback or an embryological anomaly was a matter for debate.35 But it was this context in which inherent sex difference—and female inferiority—was taken as a matter of unquestionable fact that shaped the scientific investigation of the internal secretions of ovaries and testes.
