Scientific American: Visualizing Sex as a Spectrum

Much of the public discourse in this arena centers on gender rather than sex, presumably because gender is understood to be somewhat subjective; it is a social construct that can be complex, fluid, multifaceted. Biological sex, on the other hand, appears to leave less room for debate. You either have two X chromosomes or an X and a Y; ovaries or testes; a vagina or a penis. Regardless of how an individual ends up identifying, they are assigned to one sex or the other at birth based on these binary sets of characteristics. [...]

The project abruptly transformed into an exercise in visualizing complexity. First, it seemed imperative to define a few terms. Sex, gender, and sexuality are all distinct from one another (although they are often related), and each exists on its own spectrum. Moreover, sex cannot be depicted as a simple, one-dimensional scale. In the world of DSDs, an individual may shift along the spectrum as development brings new biological factors into play. The density of science underlying this phenomenon compelled a shift towards intersex as the primary focus of the visualization. [...]

DSDs—which, broadly defined, may affect about one percent of the population—represent a robust, evidence-based argument to reject rigid assignations of sex and gender. Certain recent developments, such as the Swedish adoption of a gender-neutral singular pronoun, and the growing call to stop medically unnecessary surgeries on intersex babies, indicate a shift in the right direction. I am hopeful that raising public awareness of intersex, along with transgender and non-binary identities, will help align policies more closely with scientific reality, and by extension, social justice.
