Fifty Shades

We’ve used this language to describe the extent of variety and shade within gender identity and expression. Whilst ‘sex’ might be limited to a narrower palette, ‘gender’ is vastly more varied in shade and hue. We understand that for some the association with the Fifty Shades book and film franchise presents issues around its depiction of BDSM, however, we’ve been inspired by iO Tillet Wright’s similar usage around “Fifty Shades of Gay“, and our desire to publish collections of podcasts and chapters in clusters of 50. There have also been books titled, “Fifty Shades of Gay” and “Fifty Shades of Feminism”, in the latter of which 50 women explored what the F-word meant to them today as an “antidote to the prevailing climate“.

‘a condition that affects people of both genders’
‘someone of the opposite gender’
‘everyone always asks which gender I identify as’

Oxford English Dictionary


Either of the two main categories (male and female) into which humans and most other living things are divided on the basis of their reproductive functions.

Oxford English Dictionary

Although some, such as biologist Dr Anne Fausto Sterling, back in 1993 argued (a little “tongue-in-cheek”) for “at least five sexes, maybe more”.

Some also conflate sex and gender but still mean sexes, “an infinite combination of biological genders exists“, as is clear by the addition of ‘biological’.

Logo / X Chromosome

Our logo is based on a zoomed-in stylised version of the X chromosome, so called because of an X factor, not directly its shape. All chromosomes are somewhat X-shaped blobs. The stages of discovery and influence of X and Y (and SRY) in sex determination have taken place only recently in 1905, 1959, and 1990.
