We're publishing new guidance to support trans people who do fieldwork (any work outside the office)! Now we need your help to get them seen so please share! inclusivefieldwork.leeds.ac.uk/trans/
a cartoon of three fieldworkers. One has a small trans flag. The logos of the university of leeds, research england, and canopy robin are shown, as well as the URL: InclusiveFieldwork (dot) Leeds (dot) AC (dot) UK (slash) trans

We're brainstorming ways to support trans folk in biomed by forming more community and networking/mentoring opportunities Would folks be interested in a Discord channel to bring folks together? Or are there other platforms people would suggest?

The Dutch equivalent of Cass, (except it’s a proper scientific review not pseudoscientific drivel like Cass) has wholeheartedly endorsed puberty-blockers and full gender affirming care for young trans people.

The review finds that wait times must be shortened, that few people detransition, and that trans youth care has enormous benefits.

My husband has taught human reproduction and development to the Cambridge medics for over three decades. When people start banging on about "only two biological sexes" he starts with "which sex: genetic, hormonal, or gonadal"? Biological sex is not binary. www.scientificamerican.com/article/sex-...

we made a critical error allowing reactionaries to make-up concepts like “biological sex” and frame them as non-ideological when it’s the exact opposite: people who undergo HRT *are literally changing their biological sex.* this is not some philosophical distinction, it is actual biological reality.

Chromosomes are biological. Hormones are biological. Anatomy is biological. Behaviour is biological. Reifying one of the many aspects of sex as the only true definition of ‘biological sex’ is a political statement that I refuse to endorse.

Before I transitioned, I ironically was accused of being a secret trans woman all the time simply because I was 5'11" Are all tall girls going to have invasive genital inspections or unnecessary genetic testing now? What a sham of a ruling devoid of both logic and empathy

Hello! I AM a biology (genetics) expert and can confirm 100% of this is true. I've seen firsthand hundreds of differences in sexual development (dsd's) in dogs. It's leaning into grade-3-level misconceptions of biology that drive these politically motivated decisions.

Without even taking into account the fact that sex and gender are not the same thing, there are so many more sexes than male and female. Someone could, for instance, have an XX karyotype but one of their X chromosomes has a fused SR-Y gene resulting in them looking like a man, despite being XX.

I’m a trans woman in my forties. Growing up without social media—and during Section 28—I knew nothing about transness and I knew no-one like me. I almost didn’t make it; I dread to think how many didn’t. You can’t tell me that returning to this state is not an intended effect of this proposed ban.

The geneticist who discovered the SRY gene on the idiocy of using it to determine "biological sex" in sport. It's far more complex than policy makers with inadequate scientific literacy would have people believe. theconversation.com/world-athlet...
theconversation.com
World Athletics’ mandatory genetic test for women athletes is misguided. I should know – I discovered the relevant gene in 1990
World Athletics says its genetic test for women ensures ‘the integrity of women’s sport’ – but science does not support this overly simplistic idea.

The number is actually 97.1% if you include the little shuffling around between nonbinary and binary identities that happened, but it is *remarkable* how rock-steady at 97-98% youth trans self-identification is. Believe kids when they tell you they're trans!!

Understated consequence of this: how can you convince your hospital board that it must keep offering trans youth care if one of the leftmost politicians in America set his new clinic at 19 and over? It sets a horrible precedent.

Fish as fluid as the ocean. 🌊 All California sheephead start life as female and move through an array of colors and body shapes as they mature. Some female adults may transition to male as social and environmental factors shift, balancing the delicate ratio of individuals in their population.

“The women’s movement has fought for centuries to avoid being defined only by biology…” Dr Anna Cody (Australia’s Sex Discrimination Commissioner) reminds us why many feminists oppose laws that define what it means to be a woman in crude binary or biological terms. Trans rights are feminist too.
