Sex vs gender – IDAHOBIT 2025

Every 17 May is IDAHOBIT – an occasion for all people to celebrate the progress we have made while also raising awareness for the discrimination, violence, and challenges that LGBTIQA+ people still face today.

In particular, trans and gender-diverse (TGD) people may have distinct healthcare and other support needs. Health services that have information about both a patient’s assigned sex at birth and their gender will generally be in a better position to provide clinically appropriate and inclusive healthcare to TGD people.

Collecting and reporting a patient’s sex and gender

Sex and gender are not the same. Some people have a different sex or gender than what was assigned to them at birth or a gender that sits outside of the spectrum of male and female. It is important that TGD people can accurately inform health services of their sex and gender in a safe and inclusive way.

About the importance of understanding the sex and gender of TGD patients, A/Prof Ronnie Ptasznik, Program Director of Imaging, says, ‘gender affirming surgeries do not remove underlying risks.’

‘For example, following gender affirming surgery, trans-women might still have prostates, and their risk of prostate cancer remains. Relevant clinicians need to know that they have a prostate.

‘Similar concerns may apply to malignancies of the uterus and ovaries and there might be radiation risks associated with pregnancies.’
