Biological sex in mammals is binary (M/F). With all our advancements in genetics/medicine we currently have no way to change an individual's biological sex.

So why does this matter?
Because Medicine.

So, let's talk about sex.

A short thread.

1/5

Examples of Differences in Sex Development (DSD) or Intersex actually help us to better understand the two separate pathways of developmental trajectories of sex in mammals.

As individuals with intersex have expressed often, 'we're not a 3rd sex, we're female or male'.

As I wrote about in #TheBetterHalf, we continue to harm both sexes by ignoring the fundamental biological differences between them.

As twice as many males have unfortunately died from #COVID19 and twice the number of females have long-COVID.

Sex chromosomes (X and Y) and the milieu of hormones that arise from them, play a fundamental role in determining and predicting everything from our life expectancy, autoimmunity risk and even what dosage of a particular drug we require.

4/5

Since every cell, tissue, organ and person has a sex, isn't it time that medicine begin to practically address the clinical implications of these basic biological differences?

Or

Should we just keep pretending they don't matter?
