In recent years, significant attention has been directed at trans women in sport. This has included the spread of misinformation and disinformation including inaccurate depictions of trans athletes in the media. In turn, some international, national, and local sporting bodies have developed policies regarding trans women that are based on opinion rather than scientific evidence.

The Australian Charter of Healthcare Rights clearly states that all people in Australia have the right to be treated with dignity and respect and to have their culture, identity, beliefs and choices recognised and respected when receiving health care.  This includes trans and gender diverse (trans) people.

Many cisgender and trans people rely on oestrogen hormone therapy – but the recurring national shortages of patches look set to continue.

Since 2020 or so, there have been recurring national shortages of oestrogen transdermal patches in Australia.

These easy-to-use skin patches are applied to the skin like a sticker and deliver oestrogen directly into the bloodstream. They contain the hormone oestradiol, an oestrogen that is naturally produced in the human body and in people recorded female at birth, it has a major role in maturing and maintaining the reproductive system. Oestradiol is also important for bone health, heart health, and maintaining mental health and wellbeing.

Content Warning: Brief mention of healthcare discrimination, gender-affirming surgeries using medical terms for body parts, and mental health. There is also a photograph of a non-binary person holding a syringe, about to inject testosterone.

Note: It is generally recommended that non-binary people are not divided up according to their sex recorded at birth, as this can shift the focus from gender towards sex in a way that can undermine non-binary identities and experiences. However, in some cases, this categorisation is important, including where there are notable differences based on sex recorded at birth that warrant acknowledgement and discussion.

Non-binary is a broad umbrella term for people who have a gender that does not fit exclusively into the woman/man gender binary. This includes a broad range of genders, including genderqueer, genderfluid, bigender, and agender.

In recent years, significant attention has been directed to trans and gender diverse (trans) people in sport. Misinformation and disinformation about trans athletes are rife, and this has been highly damaging to trans people and their allies.

Part of the challenge in contesting this misinformation and disinformation is the lack of scientific evidence regarding whether gender affirming hormone therapy (GAHT) has a positive or negative impact on athletic performance. Our recently published reviews on the impact of GAHT on physical performance and sports participation clearly outline the limitations and gaps in research in this area.

This lack of evidence has allowed the spread of misinformation in the media about trans people in sport to continue, and sporting bodies have developed policies based on opinion rather than evidence.

What are we doing to address the gap in research?

2023 has been challenging as the trans community face unprecedented levels of anti-trans discrimination and violence. With so much of the harmful rhetoric based in misinformation and disinformation, this year we have prioritised science communication and have spent significant time and energy engaging with government, community organisations and other key stakeholders such as sporting bodies, to ensure accurate, evidence-based information directs policies that impact trans people.

The Australian Professional Association for Trans Health (AusPATH) is the national peak body for people working to improve the health, rights and well-being of trans and gender diverse (trans) people. This year, the biannual AusPATH Conference was held in Melbourne from 2-4 November.

The Trans Health Research Team presented 12 oral presentations and 3 posters over the 3-day conference, sharing both recently published and yet-to-be-published research to an audience of over 500 attendees.

There is no consensus on optimal oestradiol levels for trans people using oestradiol gender-affirming hormone therapy (GAHT). International guidelines vary, suggesting goal oestradiol concentrations anywhere between 250 pmol/L and 1000 pmol/L, but these recommendations are based on expert opinion and the approximate range for cisgender women across the menstrual cycle, rather than clinical evidence.

Over the last few years, we have observed an increase in trans people in Australia seeking high doses of oestradiol, while their doctors understandably have reservations about prescribing oestradiol GAHT well above levels recommended in current Australian guidelines.

Results showed significant reductions in gender dysphoria, depression, and suicidality after 3 months with early testosterone GAHT use compared to standard care. Remarkably, over half of the study participants receiving testosterone experienced resolution of "thoughts of hurting themselves or that they were better off dead".

What are oestradiol implants?

An estradiol implant is a small, slow-release pellet containing the hormone oestradiol. Implants are inserted into the fatty tissue under the skin, preferably in the top of the buttock.

The Australian Informed Consent Standards of Care for Gender Affirming Hormone Therapy recommend a starting dose of 100mg every 6-12 months, and a maximum dose of 200mg every 6-12 months. In a recent survey, we asked trans people using oestradiol implants about the frequency of their implants, and the majority reported that their implant was replaced when their oestradiol blood concentrations fell below a certain level (57%), indicating the importance of regular blood tests. 15% of the people we asked, had their implant replaced 6 monthly, while 4% had it replaced every 9 months, and 8% yearly.

I’m over 18 and thinking about gender-affirming hormone therapy. Where do I start?

There is a lot of information out there about gender-affirming hormone therapy (GAHT). Not all of it is correct, and some of it might be applicable elsewhere, but not in Australia. So, let’s start with the basics.

Trans and gender diverse people have all different types of feelings about GAHT. While some people want to start hormones and see big changes as quickly as possible, others want to take it slowly, and it may take years to decide that GAHT is right for them. Some people might pause their GAHT for different reasons (e.g., to achieve a pregnancy), some are happy to stop their GAHT after achieving certain physical changes, and others don’t want GAHT at all. All of these are valid pathways, and no one pathway makes a person more or less trans.

The National Suicide Prevention (NSP) Conference is an annual conference hosted by Suicide Prevention Australia. The conference provides a space for suicide prevention experts to showcase evidence-based solutions and robust discussion, and is widely regarded as the premier event in the suicide prevention calendar.

Despite almost half of trans people attempting suicide at some point in their lives, trans suicidality has been notably absent from previous years’ conferences.

What is TRANSform?

TRANSform: An Australian longitudinal gender health study is an ongoing research project that aims to produce priority-based and community-led research to improve the health and wellbeing of the trans and gender diverse community.

Anyone who has a gender that is different to what was presumed for them at birth, currently living in Australia, and aged 16+ can join TRANSform. Since its launched three years ago, over 2,000 trans and gender diverse (trans) people from all over Australia have taken part, making TRANSform the largest ever trans research project in Australia.

Not only is TRANSform the largest project in terms of participant numbers but it is also the largest ever trans-led project in Australia. Trans people lead every stage of the research, from design to implementation, data analysis and reporting.

What is oestrogen?

Oestrogen, or estradiol, is a sex hormone that is produced naturally in our bodies, and in people who were born with ovaries it is the main sex hormone. Testosterone is produced by the testicles, so people born with testicles will tend to have a naturally higher level of testosterone, and it will be their main sex hormone.

2022 has been a year of challenges but also opportunity and hope. We have experienced a climate of intense, harmful political 'debate', often contrary to scientific evidence and the lived-experience of the trans community. Whilst we are steadfastly focused on undertaking scientific research to improve trans health, in 2022, our voices as science communicators has never been more important.

As clinicians treating trans people and as researchers in trans health where >50% of our team are trans people with lived experience, we have a unique perspective to educate the public and influence policy debate. In 2022, we shared our research through media, peer-reviewed publications, national and international meetings, seminars, and conferences, and in training sessions with healthcare professionals. Refreshingly, we’ve seen Australians rebuke the politics of division at the Federal election and our resilient community come together.

Below are some highlights from our year.

I want to make a brief intervention here to highlight an aspect of degrowth climate mitigation strategy that has so far been inadequately developed.  It is widely understood that scaling down less-necessary forms of production can contribute substantially to decarbonization, in two direct and obvious ways. First, it directly reduces emissions in addition to what can be achieved through efficiency improvements and renewable energy deployment.  Second, it reduces total energy demand and therefore makes it possible to decarbonize the energy system much more quickly, because it is not necessary to install as much new infrastructure, and the process of doing it involves less extraction and emissions. These are powerful benefits.

But there are several other benefits to a degrowth scenario that are less widely understood and are worth considering.
