Beyond X&Y

Are you a biomedical expert who wants to help fight for trans rights and evidence based medicine?

Check out this thorough, extremely helpful guide on how to submit official comments to defend gender affirming care:

Biology is so cool!!!

I fully used to believe that "man flu" was simply due to patriarchy - that women sucked it up because they had to keep being moms/caregivers, while men were just being whiny

Then I personally experienced it myself after starting T. It's so real!!

🚨 Requesting help:

I am looking for an agent who can facilitate more speaking gigs, podcast appearances, and interviews with journalists

I want to more widely share my story and expertise as a trans geneticist who understands the reality and complexity of "biological sex" 🏳️‍⚧️🧬

Please signal boost?

I also welcome any direct connections people may have to podcasts who need a guest, or organizations who need a speaker (it's about that time to start planning for Trans Day of Visibility!)

If you have questions or ideas, DM me or email me at jey (at) beyondxandy (dot) org

Abortion access, gender affirming care, and access to Prep and AIDS medications are all issues of bodily autonomy and founded in legitimate medical research

But that doesn't matter to fascists. Enforcing strict gender binaries and destroying science maintains power among a few cishet wealthy men

This is why it's important to vocally fight for trans rights - it works!

Big win 🎉🏳️‍⚧️

1. Anti-trans news story lying about "trusting the science" that "biological sex" is binary
2. Scientific resources explaining the complexity of sex and gender
3. Good faith questions that could use a trans geneticist's brain

A London Underground advertisement for testosterone for men

Makes me feel insane to live in a world that's persecuting trans folk while simultaneously doing big billboards advertising gender affirming care to cis people???

Defining legal sex, the Supreme Court failed to address vital wording in the Equality Act 2010 TLDR:

"Biological sex" is theological sex. Religion cannot act openly in the UK as it can in the USA.

Also the project and the tactics come from the USA.

In 2022 I started tracking changes in how news outlets were describing trans people, and set up a bot to record every article pushed to the Google News index based on a handful of search phrases, including “biological sex” in both the US and UK. The amount in 2023 alone was absolutely staggering.

Why “biological sex” may not mean what you think There are a lot of terms to refer to a person’s sex: sex, birth sex, natal sex — and more contentiously, assigned sex at birth and biological sex. The nuances and differences aren’t always important....

Scientists reject a binary view of human sex at NIH symposium

They say complexities of human sex require more inclusive definitions, and research data need to reflect biological complexity

chart header reads: Fields Under Fire. Some research fields have been heavily affected by grant terminations implemented by the US National Institutes of Health (NIH) under President Donald Trump. More than half of the active, NIH-funded projects about gender and sexual minorities (LGBT+) have been cancelled. chart #1 shows that 50.6% of grants containing the terms "LGBT/LGBTQ/LGBTQ+" in the title or abstract were terminated. chart #2 shows that 45.8% of grants containing the term "transgender" in the title or abstract were terminated. chart #3 shows that 45.5% of grants containing the term "vaccine hesitancy" in the title or abstract were terminated. chart #4 shows that 3.4% of grants containing the terms "HIV" or "AIDS" in the title or abstract were terminated.

since it's behind a paywall now, I wanted to share this graph from "How Trump 2.0 is slashing NIH-backed research — in charts" (Nature, April 2025). Say it with me: the anti-trans/LGBTQ+ movement is an anti-science movement:

“Plato does not agree with the narrative that there are two biological sexes and that everyone should be heterosexual. So it is controversial. But that's the whole point of including him in the syllabus.”

Can't promise answers to every question or commentary on every piece of news

We're a volunteer team: Mainly one tired trans science communicator, helped by their queer scientist friends (also tired)

But we at least want to be a resource to stay up to date about science-related trans rights issues

🧵 Big News:

Today was my last day at work. I resigned to completely dedicate my time to trans activism as long as it's financial feasible

I'll be writing a book debunking anti-trans attacks that falsely claim to be founded in "biology" and making educational resources at @beyondxandy.bsky.social

No, *you* represent the viewpoint of most biologists

Every major medical and biology organization accepts that sex is not binary, transness is innate, and that gender affirming care is life saving, evidence based medicine

See a list of statements below: bsky.app/profile/beyo...

Federal employees file complaint against Trump administration's ban on gender-affirming care The Trump administration faces a legal complaint from government employees over a new policy eliminating coverage for gender-affirming care in federal health insurance programs.

@rikiwilchins.bsky.social 2026 Jan 2 AP: HRC files EEOC complaint on behalf of 4 fed employees against Office of Personnel Management policy banning coverage of “chemical & surgical modification" of sex for all federal employees, saying it constitutes sex-based discrimination.

Attorney General James Leads Lawsuit Challenging Federal Attack on Gender-Affirming Care NEW YORK – New York Attorney General Letitia James today led a coalition of 18 other states and the District of Columbia in filing a lawsuit to stop the U.S

A coalition of 19 states and DC have filed a lawsuit challenging the Kennedy declaration seeking to ban gender affirming care for trans youth by fiat by creating a federal "standard of care" based on pure pseudoscience.

The FDA prioritized attacking trans chest binders, which pose little risk, while allowing most pharmacogenomic DTC tests to market without being labeled as medical devices

This is why biotech isn't fighting this government. They'll make more money with lax regulations

Mushroom evolutionary biologist here.

We’re well aware of the fact that sex and gender isn’t a binary. Happy to talk about the fungus with 28,000 distinct sexual identities anytime.

Trans rights are human rights! 🏳️‍⚧️

“All evolutionary biologists know that variation itself is life’s only irreducible essence”—Gould

Evolutionary biology is the study of how complicated and diverse life can be; the field has its jerks, but a good evolutionary biologist learns pretty fast that life doesn’t like boundaries or binaries

I consider myself a biological anthropologist who sometimes has to engage with evolutionary biologists.

In EB, too often the conclusions are about how biology determines culture. In BA, we learn that culture & biology are interrelated, affecting each other but not determining (that’s too narrow).

My training was very firmly in an evolution oriented EEB dept. As a visibly GNC queer, I have actually found EEB spaces to be a more welcoming home than neuroscience. Working on animal sexual behavior from an EEB perspective really highlights the sheer diversity of ways that sex can be organized.

Rather excellent thread

Let’s be very clear here. This is exactly why it was exceptionally unwise of the Supreme Court to wade into this space using ‘biological sex’ as a defining concept, because as soon as you talk to actual biologists the simple binary unravels. Not a stable basis for law.

Resources for LGBTQIA+ ecologists - British Ecological Society A collection of websites and literature for LGBTQIA+ ecologists and allies.

Ecologist here, we know plenty about the diversity of life, and as the @britishecologicalsociety.org we actively support the inclusion of trans people alongside all the many ways of simply being human. Dawkins does not represent or speak for us.

Actually see the opposite honestly been told time and time again that diversity in gene expression and behavior is an advantage in species not a take away. I don‘t think you understand evolution and genetics enough if you’re transphobic and homophobic

Geneticist had the best response to an office pool about whether my kid would be a boy or girl: “Probably”.
