> “Sex” could be interpreted to mean a statement about chromosomes. Yes, it could - by people who don't know what the word "sex" means. Sex isn't about chromosomes, it's about gametes, and sex chromosome variants aren't separate sexes. For example, people with Klinefelter Syndrome (XXY) are male. This isn't hard. https://colinwright.substack.com/p/sex-chromosome-variants-a... |

> What’s important to note is that the presence of a Y chromosome, or two, or three, etc., all result in the development of testes and therefore these individuals are biologically male. Likewise, individuals with additional or fewer X chromosomes, in the absence of a Y, all develop ovaries and are therefore biologically female.
Looking at things like testes and ovaries is only one part of things, and not some universal definition scientists accept. The author even admits in the comment some people may have both. We also know that some people make have one of these but appear oppositely on the inside/outside.
> This isn't hard.
From my experience, it is deeply complex.
> Effectively regulating sports divisions based on sex using science is impossible. There are no singular or combinations of objective criteria that can define each sex. Prior attempts to govern sports eligibility based on sex using existing testing methods have failed to provide a workable solution based on chromosome composition, physical exam, etc. In other words: we have no way to consistently differentiate male from female and we have never possessed the ability to do so. Gender and sex are not the same thing. Sex is typically assigned at birth based the appearance on appearance of external genitalia and or chromosomal makeup, whereas gender is socially constructed and may vary from culture to culture and/or change over time. However, sex is difficult to dichotomize into two binary divisions because there are a number of different chromosome compositions consistent with either male or female phenotypes. The phrase “biological sex” is meaningless and is ill-advised.
