Aisling O'Reilly Kane, who legally transitioned to male at 18, is now seeking to return to her original legal sex but says she has encountered significant unanswered questions regarding her records, healthcare, and future life in Ireland. Nearly a decade after legally changing her sex, O'Reilly Kane, now 28, has detransitioned, stopping hormone treatment over a year ago. However, some physical changes, such as a deeper voice and the return of facial hair, remain.
Her passport and birth certificate currently record her as male due to a Gender Recognition Certificate obtained in 2015, the day after her final secondary school exams. Under Ireland's Gender Recognition Act 2015, this certificate changes a person's legal sex "for all purposes." O'Reilly Kane expressed concern that in an emergency, such as a medical incident, healthcare providers might not have access to her complete medical history or accurately reflect her current identity and past transition.
She believes a gap exists in services and guidance for individuals seeking to reverse their transition, with no clear official pathway to explain what happens to medical and legal records. While Irish law permits the revocation of a Gender Recognition Certificate, O'Reilly Kane highlights a lack of clarity on the subsequent steps, particularly concerning medical records and daily life.
O'Reilly Kane's journey began in childhood, with early experiences as a tomboy and an interest in her father shaving. At 13, the idea of a mastectomy emerged after a relative underwent the procedure. She attributes some of her early decisions to a perceived childhood brain injury affecting her development and lessons about women's historical struggles, which she felt made her fear being female. By age ten, she had a plan to transition to male legally at 18.
At 15, she came out as gay and, through the LGBTQ+ youth organization Belong To, found what she considered a legitimate path towards her long-held decision. She socially transitioned and legally changed her name in 2015. Shortly after her final exams, she underwent a double mastectomy and began testosterone treatment, later starting puberty blockers by age 21.
Now, navigating the consequences of decisions made as a teenager, O'Reilly Kane has contacted government ministers about her situation, receiving replies from only three. Her inquiry to the Minister for Health regarding the impact of discrepancies between her legal status and medical history on her epilepsy treatment was redirected to the Health Service Executive (HSE), with the Minister stating it was outside his area of expertise.
She points to the distinction taught between sex and gender, which she encountered through Belong To's training programs for supporting LGBTQ+ youth. O'Reilly Kane questions why a Gender Recognition Certificate changes legal sex if sex and gender are considered different. Her experiences in a single-sex secondary school, where she felt comfortable with short hair and trousers, contrasted with a mixed-sex school environment that she says intensified her desire for testosterone.
By 2024, working as a special needs assistant in a girls' secondary school, O'Reilly Kane began considering detransitioning, ultimately deciding against it to avoid exposing her students to gender ideology. A pivotal moment occurred during a history lesson where a male teacher apologized for historical mistreatment of women. This resonated with O'Reilly Kane, who felt traumatized by similar narratives at her age, leading her to feel the need to disguise herself as male. The same historical context, she explained, triggered her transition and was now triggering her desire to detransition.
Currently, few people in O'Reilly Kane's life are aware of her detransition. She describes living between the "gender bubble" and everyday life, where her appearance does not always align with her legal identity. She emphasizes that appearance is not identity and that she knows she is female.
She places significant responsibility on the government and education system for creating a situation where individuals, colleagues, strangers, and officials must navigate complex issues without clear guidance. The Department of Education and Youth stated that schools must provide safe and inclusive environments and respond to gender-related distress sensitively, but confirmed no specific guidance exists for detransitioning, with schools expected to address individual circumstances.
The Department of Social Protection outlined that Gender Recognition Certificate applications do not require medical processes, only a declaration of intent to live in the preferred gender. Once granted, the preferred gender is recognized by the state and updated on the Personal Public Service number record. Issues of care and support related to transitioning are handled by the Department of Health/HSE.
The system for gender recognition in Ireland has expanded significantly. In 2005, only five people were referred to gender services, a number that rose to hundreds by 2024, with a waiting list of over 2,500 people. The demographic of those referred has also shifted, with teenage girls and young women becoming a growing referral group internationally. Legally, 336 people over 18 applied for Gender Recognition Certificates in 2024, with 334 granted.
Neither the National Gender Service nor the Department of Social Protection publishes figures on the number of people revoking Gender Recognition Certificates or seeking support after detransitioning. While the system tracks those entering it, records for those seeking to reverse their transition appear to be absent.
Evidence suggests that most people who transition do not later seek to reverse their decision, though Ireland has not published long-term outcome data. Stephen McMahon of the Irish Patients' Association stated that patients have an ongoing right to make decisions about their care, including changing course, and that a later change of mind does not invalidate an original decision, nor should it leave a patient without appropriate care.
The HSE, National Gender Service, and Department of Health had not responded to requests for comment regarding the process of revoking a Gender Recognition Certificate or the state's responsibility in supporting individuals post-transition by the time of publication.
O'Reilly Kane believes her delayed development and full medical history should have been considered, but concludes, "It’s just clear to me that legally, this is not working." Her experience raises questions about whether Ireland's legal framework for gender recognition adequately supports those who later wish to reverse that decision.
