The literature on exploratory therapy consists almost entirely of clinical essays, single-case reports and one small case series, written mainly by the therapists who practice it. The only figures come from a review of 128 adolescents assessed at England's former national youth gender service: 12 (9.4%) whose distress began in adolescence stopped seeking medical treatment during an extended assessment averaging 6.6 sessions over 9.6 months (Churcher Clarke & Spiliadis, 2019). Nine of the 12 were girls and seven had an autism diagnosis; seven became comfortable with their birth sex, while five still identified as trans but no longer wanted hormones. Individual cases describe gender distress coming to be understood alongside grief, family conflict or abuse, such as a history of maternal abuse emerging only after 18 months of therapy (D'Angelo, 2025), or a 17-year-old who decided not to transition after five years of therapy (Lemma, 2018). Outcomes are not uniform: D'Angelo's patient still began estrogen at 18, and a 15-year-old who came to identify as gay and gender-fluid put a hormone referral on hold rather than ending it (Spiliadis, 2019).

Proponents describe the approach as open-ended and non-directive. Lemma explicitly rejects therapy aimed at changing identity, and Spiliadis frames it as a middle path between simple affirmation and conversion efforts. Critics argue the opposite: an essay posing 16 self-described leading questions compares the approach's language with past "ex-gay" programs and concludes it "may be unethical," though it presents no data and itself relies on affirming-care evidence later rated low quality (Ashley, 2023).

Limits of the evidence

No study compares exploratory therapy with other approaches, uses validated measures of gender distress or mental health, or follows patients over the long term. The case series reports only the 12 cases with the outcome of interest, says nothing about the other 116, and tracked results for roughly 9 to 10 months. Case reports are chosen, anonymized and interpreted by the treating clinician, often an author with a stated position on youth gender medicine, and patients in long-term private psychoanalysis are an unusual group. The evidence shows that some young people's requests for medical treatment change during extended exploration, but not how often, for whom, or whether the therapy itself causes the change.
