It's !

Gender-affirming care is associated with much lower rates of depression and suicidality among young people. Psychological research shows that just referring to someone by their preferred name and pronouns can have a dramatically positive effect on their mental health. Good gender-affirming care allows for the exploration of identity and creates a space where doubt, questioning, and reflection are welcomed and embraced.

✨ New podcast episode ✨

I had the pleasure of joining The Genderq***r Menopause Coach podcast with Lasara Firefox Allen, MSW, for a conversation on menopause, informed consent, and non-linear gender trajectories.

We explored how menopause and gender-affirming care often intersect: some people experience menopause because of gender-affirming care, while others seek gender-affirming care because of menopause. Both are profound moments of embodiment and transition, yet they’re rarely discussed together.

Within an informed-consent model, this means bringing menopause into gender-affirming care conversations in ways that are lifespan-oriented, accessible, and free of cisnormative or transnormative assumptions—while also recognizing that detransition and other non-linear gender trajectories may intersect with menopause as people pause, discontinue, or reshape aspects of their transition for various reasons. As healthcare providers, our role is to accompany and support this process of self-determined embodiment at every stage of life.

🌟Just published!

I’m honoured to contribute to the 2025 special issue of Canadian Psychology / Psychologie canadienne, spotlighting CPA award recipients.

📝 My article:
“When Cisnormativity and Transnormativity Are in Bed Together: Exposing the Underbelly of Disinformation-Fuelled Detransition Panic”

This piece challenges dominant clinical and cultural narratives about detransition and unpacks the ideological machinery behind today’s disinformation-driven panic.
In a divisive sociopolitical climate, detransition is too often misrepresented—fuelling stigma and harming both detransitioners and gender-diverse communities. This article cuts through the noise to offer nuance and expose the biases distorting public understanding.

New online-first in the journal Canadian Psychology:

'It is time for gender-affirming care: Trans+ experiences and perspectives on presurgical mental health assessment prior to transition-related surgery referral'
- Dupasquier, J. R., Malone, R., Reynolds, K., & Westmacott, R. P.

"In the present study, trans and gender-diverse individuals seeking gender-affirming surgeries mostly reported that presurgical mental health assessment was not helpful in their preparation for gender-affirming surgeries or for their mental health/physical recovery after surgery despite provincial/territorial requirements for these assessments. Most participants wanted to access transition-related surgeries as they would other surgeries: discuss the risks and benefits with their family doctor and receive a direct referral to a surgeon. Results suggest that health care system reform and more flexible, affirming, and supportive presurgical processes may be needed."

Il a été souligné avec bienveillance que l’utilisation de pièces de casse-tête dans la trousse sur la détransition évoquait une iconographie problématique, souvent associée à des représentations pathologisantes de la neurodivergence. Cette rétroaction a été entendue, prise en compte, et le design a depuis été modifié. La trousse a maintenant une nouvelle apparence — toujours gratuite, toujours ancrée dans une approche "trauma-informed", et plus alignée avec ses valeurs fondamentales.

✨ Ressource gratuite portant sur la détransition✨
(en anglais seulement)

Cette trousse gratuite s’adresse aux professionnel·le·s de la santé. En s’appuyant sur des données probantes, elle fournit un encadrement et des recommandations permettant aux professionnel·le·s de mieux accompagner les personnes qui détransitionnent ainsi que celles ayant des parcours de genre non linéaires. Dans un contexte souvent marqué par la désinformation et la mésinformation, cette ressource apporte clarté, réflexions pratiques et considérations éthiques afin de favoriser une prise en charge éclairée et bienveillante.

It was kindly pointed out that the use of puzzle pieces in the detransition toolkit echoed harmful iconography often associated with pathologizing views of neurodivergence. That feedback was heard, reflected upon, and the design has since been changed. The toolkit now has a new look—still free, still trauma-informed, and now more aligned with its core values. 💜

✨Beyond the Trans-Cis Binary: A Healthcare Provider’s Guide to Detransition and Non-Linear Gender Trajectories ✨

Designed to address the growing misinformation and disinformation surrounding detransition, the toolkit provides healthcare providers with evidence-based guidance to better support detransitioners and individuals with non-linear gender trajectories.

Inside, you’ll find:
✅ The essentials of what healthcare providers need to know about detransition
✅ Complex and nuanced perspectives on detransition, moving beyond simplistic or one-size-fits-all narratives
✅ A breakdown of common misconceptions and misleading narratives, including how to identify misinformation and disinformation
✅ Key recommendations for inclusive and informed care

The toolkit can be used as a comprehensive resource or as stand-alone info sheets for quick reference.
