Of sex and gender

The word ‘gender’ has been used as a synonym for ‘sex’ since at least the fourteenth century, although this usage was described as “Now only jocular” in the first edition of the Oxford English Dictionary (1899). The nonjocular use of gender, however, has undergone a dramatic revival since the 1960s when feminist scholars introduced a distinction between biologically determined sex and socially constructed gender1. A number of commentators2,3,4,5 have noted (with disapproval) a more recent increase in the use of ‘gender’ as a synonym for ‘sex’ within the biological sciences. To quantify this trend, I searched the Science Citation Index (SCI) for all titles containing ‘sex’ and ‘gender’ for each year from 1988 to 1999. For comparative purposes, similar searches were performed for articles listed in the Social Sciences Citation Index (SSCI) and the Arts & Humanities Citation Index (AHCI). These searches revealed that the sex-to-gender ratio of SCI titles has undergone a dramatic decline from more than 10 to 1 in 1988 to less than 2 to 1 in 1999 (Fig. 1), and that titles containing ‘gender’ outnumber those containing ‘sex’ in the AHCI (all years) and the SSCI (all years since 1989).

‘Sex’ is used in some biological contexts where ‘gender’ is never used as a synonym (for example, sex in the sense of genetic recombination, sex chromosomes). Therefore, it is interesting to restrict the above analysis to contexts in which the two terms are used as synonyms. For example, there were seven SCI titles containing ‘sex differences’ for each title containing ‘gender differences’ in 1988, but ‘gender differences’ have outnumbered ‘sex differences’ since 1996. Similarly, ‘gender-specific’ was almost non-existent in SCI titles from 1988, but now approaches parity with ‘sex-specific’.

Cursory inspection revealed that the increased use of ‘gender’ in SCI titles does not reflect an equally dramatic shift in scientific interest from understanding the biological determinants of sex to understanding the cultural determinants of gender. Rather, the rise of ‘gender’ appears to be the result of well-meaning attempts to signal sympathy with the ideas and goals of feminism. This has had the paradoxical outcome of undercutting and blurring the distinction which feminists sought to emphasize by distinguishing sex from gender.
