RESUMEN

BACKGROUND: The effect of gender-affirming testosterone therapy (TT) on breast cancer risk is unclear. This study investigated the association between TT and breast tissue composition and breast tissue density in trans masculine individuals (TMIs). METHODS: Of the 444 TMIs who underwent chest-contouring surgeries between 2013 and 2019, breast tissue composition was assessed in 425 TMIs by the pathologists (categories of lobular atrophy and stromal composition) and using our automated deep-learning algorithm (% epithelium, % fibrous stroma, and % fat). Forty-two out of 444 TMIs had mammography prior to surgery and their breast tissue density was read by a radiologist. Mammography digital files, available for 25/42 TMIs, were analyzed using the LIBRA software to obtain percent density, absolute dense area, and absolute non-dense area. Linear regression was used to describe the associations between duration of TT use and breast tissue composition or breast tissue density measures, while adjusting for potential confounders. Analyses stratified by body mass index were also conducted. RESULTS: Longer duration of TT use was associated with increasing degrees of lobular atrophy (p < 0.001) but not fibrous content (p = 0.82). Every 6 months of TT was associated with decreasing amounts of epithelium (exp(ß) = 0.97, 95% CI 0.95,0.98, adj p = 0.005) and fibrous stroma (exp(ß) = 0.99, 95% CI 0.98,1.00, adj p = 0.05), but not fat (exp(ß) = 1.01, 95%CI 0.98,1.05, adj p = 0.39). The effect of TT on breast epithelium was attenuated in overweight/obese TMIs (exp(ß) = 0.98, 95% CI 0.95,1.01, adj p = 0.14). When comparing TT users versus non-users, TT users had 28% less epithelium (exp(ß) = 0.72, 95% CI 0.58,0.90, adj p = 0.003). There was no association between TT and radiologist's breast density assessment (p = 0.58) or LIBRA measurements (p > 0.05). CONCLUSIONS: TT decreases breast epithelium, but this effect is attenuated in overweight/obese TMIs. TT has the potential to affect the breast cancer risk of TMIs. Further studies are warranted to elucidate the effect of TT on breast density and breast cancer risk.

RESUMEN

BACKGROUND: While many transgender and gender diverse individuals rapidly achieve amenorrhea on testosterone, emerging data have identified that breakthrough bleeding can occur in up to one-third of individuals with long-term use. Breakthrough bleeding can worsen dysphoria and patients may seek management to reattain amenorrhea. Because of this, there is a need to assess efficacy of management approaches. OBJECTIVE: The primary aim of the study was to evaluate methods used by patients and their providers to manage breakthrough bleeding which arises after 1 year of testosterone use. Secondary aims included describing the diagnostic approaches to breakthrough bleeding, and proposing an algorithm for classification and management of breakthrough bleeding in this patient population. STUDY DESIGN: This was an institutional review board-approved single tertiary center, retrospective chart review of transgender and gender diverse individuals on testosterone gender affirming hormone therapy who experienced breakthrough bleeding after 1 year of use. Charts were reviewed to determine patient characteristics, testosterone use, and breakthrough bleeding management approaches. RESULTS: Of the 96 individuals who had been on testosterone for 1 year and experienced breakthrough bleeding, 97% (n=93) engaged in at least 1 approach to management. The mean age at initiation of testosterone was 21.9 (standard deviation 5.4) and the median duration of time on testosterone was 54.5 months (interquartile range 33.5, 82). Only 16% (n=15) were using menstrual suppression at the time of their breakthrough bleeding episode. Breakthrough bleeding was successfully managed in 77 (79%), following between 1 and 4 attempted approaches. More than half of management attempts (63%) were successful on the first try. When management approaches were analyzed independently, the range of success associated with any particular approach was between 33% and 100%. Other than hysterectomy, which was fully successful at managing breakthrough bleeding, no approach was significantly better than no intervention. This was true both for individuals who did and did not bleed with missed testosterone doses. Regardless of what approach was used, after a failed attempt, the next attempt was successful in more than half of individuals. Of the 16 who underwent hysterectomy, 1 did so in part as a first line approach to manage breakthrough bleeding. CONCLUSION: In this study, use of medical management methods was not found to be superior to observation alone in the management of breakthrough bleeding. In the absence of data supporting superiority of any method, we recommend tailoring method attempts to patients' goals.

RESUMEN

While there is considerable overlap in the treatment of patients with intersex traits and differences in sex development (I/DSD) with transgender and gender diverse (TGD) youth, the initial medical evaluation varies significantly. I/DSD youth often present due to differences in genitalia development in infancy or pubertal development in adolescence, and this leads to comprehensive biochemical, radiologic, and genetic evaluation. TGD youth, however, tend to have typical development noted at birth and during puberty, but present with a gender identity that does not align with their sex assigned at birth and do not require evaluation for underlying pathology. For both I/DSD and TGD youth, the mainstays of treatment are to better align one's physical appearance to their gender identity. This review discusses the non-medical and medical interventions utilized in gender affirming care. A multidisciplinary team of mental health providers, pediatric medical providers, and surgeons is recommended for providing gender affirming care to both I/DSD youth and TGD youth and their families. Radiologists have an important role in initial evaluation of I/DSD youth and in ongoing monitoring of growth and bone mineral density during puberty induction in I/DSD and TGD youth.

RESUMEN

Turner syndrome (TS) is a sex chromosome abnormality characterized by short stature and primary hypogonadism with increased risk for cardiovascular disease, osteopenia, metabolic syndrome, diabetes mellitus, abnormal liver enzymes, and impairment of nonverbal learning skills. Gender-diverse youth include youth who have a gender identity that is different from their sex assigned at birth. They have an increased risk of suicidality, which is decreased in those who receive gender-affirming care. There have been no prior reports on the association or management of gender-diverse youth with TS. We describe 3 cases of gender-diverse youth with TS that highlight the importance of discussing gender identity in patients with hypogonadism in need of sex hormone replacement. Goals of care should be discussed to determine whether estrogen or testosterone replacement aligns best with gender identity. If a patient chooses to start testosterone, special considerations of risks such as erythrocytosis, osteopenia, and cardiovascular disease should be discussed in relation to their TS.

RESUMEN

Purpose: Gender-affirming hormones (hormones)-the use of sex hormones to induce desired secondary sex characteristics in transgender and nonbinary (TGNB) individuals-are vital health care for many TGNB people. Some hormone providers require a letter from a mental health provider before hormone initiation. We explore the perspectives of TGNB individuals regarding the impact of the letter requirement on their experience of care. Methods: We conducted semistructured interviews with 21 TGNB individuals who have sought or are receiving hormones. We purposively sampled respondents who were (n=12) and were not (n=8) required to provide a letter. An Advisory Board of transgender individuals guided the methodology. Interviews were transcribed verbatim and coded both inductively and deductively. Results: We identified three themes related to the letter requirement: (1) Mental health: While participants appreciated the importance of therapy, the letter requirement did not serve this purpose; (2) Trans identity: The process of obtaining a letter created doubt in participants' own transness, along with a resistance to the pathologization and conflation of mental illness with transness; and (3) Care relationships: The letter requirement negatively impacted the patient-provider relationship. Participants felt the need to self-censor or to perform a version of transness they thought the provider expected; this process decreased their trust in care professionals. Conclusion: A letter requirement did not improve mental health and had several negative consequences. Removal of this requirement will improve access to hormones and may paradoxically improve mental health.

RESUMEN

Purpose: Transgender women are disproportionately affected by HIV and are underutilizing preexposure prophylaxis (PrEP). The lower uptake of PrEP by transgender women may be, in part, owing to the perception that taking PrEP may lower the efficacy of gender-affirming hormone therapy (GAHT) or to provider concerns that GAHT may lower the efficacy of PrEP. Methods: DISCOVER was a randomized, double-blind, noninferiority trial comparing emtricitabine (FTC, F) and tenofovir alafenamide (F/TAF) versus emtricitabine and tenofovir disoproxil fumarate (F/TDF) as PrEP among transgender women and cisgender men who have sex with men (MSM). This nested substudy of the DISCOVER trial compared the exposure of the active intracellular metabolites of FTC and tenofovir (TFV), FTC triphosphate (FTC-TP) and TFV diphosphate (TFV-DP), in peripheral blood mononuclear cells (PBMC) among transgender women receiving GAHT versus MSM within the F/TAF and F/TDF groups. Results: Our results demonstrate that TFV-DP and FTC-TP levels in PBMC were comparable between transgender women on GAHT and MSM receiving F/TAF, and between transgender women on GAHT and MSM receiving F/TDF. TFV-DP concentrations remained above the EC90 of 40 fmol/106 cells across all groups. No clinically significant drug-drug interactions of GAHT were observed with either F/TAF or F/TDF in this subanalysis. Conclusions: These findings are consistent with the clinical pharmacology of GAHT, FTC, TDF, and TAF reported in previous studies, and support the continued use of F/TAF and F/TDF for PrEP in transgender women.Clinicaltrials.gov registration number: NCT02842086.

RESUMEN

Purpose: To describe barriers to care for a cohort of transgender and nonbinary (TNB) youth and examine factors associated with delays in receiving puberty blockers (PBs) or gender-affirming hormones (GAHs). Methods: We used longitudinal data from a prospective cohort of TNB youth seeking care at a multidisciplinary pediatric gender clinic between August 2017 and June 2018. We calculated the time between (i) initial clinic contact, (ii) phone intake, (iii) first medical appointment, and (iv) initiating PBs/GAHs. We estimated Kaplan-Meier curves for each time-to-care interval and used Cox regression models to estimate hazard ratios (HRs) for factors hypothesized to be barriers and facilitators of care. Results: Our cohort included 104 youth aged 13-20 years. The median time from contacting the clinic to initiating PBs/GAHs was 307 days (range, 54-807). Lower income level, Medicaid insurance, and lack of family support were associated with longer times from contacting the clinic to completing the first medical appointment. In addition, older youth experienced longer times to first medical appointment relative to youth aged 13-14 years. Youth younger than 18 years of age who did not complete a mental health assessment before their first medical appointment experienced delays from first medical appointment to initiating PBs/GAHs (HR=0.44, 95% confidence interval, 0.22-0.88). Conclusion: Certain subsets of youth disproportionately experienced delays in receiving gender-affirming medications, and these factors varied by stage of care engagement. Given the association between gender-affirming care and improved mental health, identifying sociostructural and clinic-level barriers to care is critically important to facilitating more equitable access.

RESUMEN

INTRODUCTION: In the last decade, healthcare for the transgender population has increased considerably in many countries thanks to depathologization movements and the easier accessibility of medical assistance. The age at which they request to start gender-affirming hormones (GAHs) is increasingly younger. The cardiovascular risk associated with hormonal treatment is a novel research field, and the published studies are heterogeneous and inconclusive. Our objective is to determine the metabolic impact of GAHs in the transgender people treated in our Gender Identity Treatment Unit. METHODS: We designed a pre-post study to analyze changes in anthropometric parameters (weight and body mass index), analytical determinations (fasting blood glucose, glycated hemoglobin, and lipoproteins), and blood pressure control in the transgender population treated with GAHs in Puerta del Mar University Hospital. These variables were collected before and one year after hormonal therapy. RESULTS: A total of 227 transgender people were recruited between 2017 and 2020, 97 (40.09%) transwomen and 136 (59.91%) transmen. The average age at which GAHs began was 18 years. Weight, body mass index, and blood pressure increased significantly in both genders. Transmen showed a more atherogenic lipid profile, with a decrease in cholesterol LDL (p < 0.001) and an increase in triglycerides (p < 0.001). The risk of developing prediabetes or diabetes did not increase one year after treatment, although non-specific alterations in carbohydrate metabolism were detected, such as an increase in glycated hemoglobin in transmen (p = 0.040) and fasting blood glucose in transwomen (p = 0.008). No thromboembolic processes or cardiovascular events were reported during the first year of treatment. CONCLUSION: In our setting, transgender people developed changes in their metabolic profiles in the first year after hormonal treatment. Both transmen and transwomen showed early alterations in lipid and carbohydrate metabolism, slight elevations in blood pressure, and a tendency to gain weight. This makes lifestyle interventions necessary from the beginning of GAHs.

RESUMEN

BACKGROUND: Pelvic pain has been reported in transmasculine individuals taking testosterone. There is a need for further investigation to increase understanding of the prevalence and risk factors of this pain. AIM: We sought to determine the prevalence of pelvic pain reported by transmasculine individuals who had both a uterus and ovaries and were taking testosterone. METHODS: We conducted an institutional review board-approved retrospective study of all transmasculine individuals who had been taking testosterone for at least 1 year and had a uterus and ovaries at the time of testosterone initiation. Charts of participating patients were reviewed to determine patient characteristics, testosterone use, and pelvic pain symptoms both before and after initiation of testosterone. OUTCOMES: Patients reported experiences of pelvic pain while on testosterone. RESULTS: Of 280 individuals who had been on testosterone for at least 1 year, 100 (36%) experienced pelvic pain while on testosterone. Of those patients, 71% (n = 71) had not experienced pelvic pain prior to starting testosterone. There were 42 patients (15%) who had pelvic pain prior to starting testosterone, 13 (31%) of whom no longer experienced pain once starting testosterone. The median (IQR) age at initiation of testosterone was 22 (19-41) years and duration of testosterone treatment was 48 (27-251) months.Those patients who experienced pelvic pain while on testosterone were significantly more likely to have also reported pelvic pain prior to starting testosterone (29% vs 7%, P < .001). These patients were also more likely to have a pre-existing diagnosis of dysmenorrhea (27% vs 7%, P < .001), endometriosis (6% vs 2%, P = .049), or ovarian cysts and/or masses (12% vs 2% P < .001). Patients with pelvic pain were also more likely to have been on a menstrual suppression agent prior to and overlapping testosterone initiation (22% vs 12%, P = .03) and to have used menstrual suppression for longer durations (median [IQR] 18 [6-44] vs 8 [4-15] months, P = .04). CLINICAL IMPLICATIONS: Pelvic pain is common in transmasculine individuals who are initiating testosterone treatment, although testosterone has both positive and negative effects on pelvic pain in different individuals. STRENGTHS AND LIMITATIONS: The major strengths of this study included large numbers of patients, ability to assess for documentation of pelvic pain prior to testosterone, and ability to determine an actual prevalence of pelvic pain. Major limitations included the study being a retrospective analysis in a single tertiary care center, the limitations of clinical documentation, and the lack of a standard pelvic pain evaluation process. CONCLUSION: More than one-third of transmasculine patients with a uterus and ovaries had pelvic pain while on testosterone, with the majority reporting onset of pain after initiating testosterone.

RESUMEN

BACKGROUND: Early puberty suppression (ePS; Tanner stages 2 and 3) through gonadotropin-releasing hormone agonists (GnRHas) and gender-affirming hormones (GAHs) interferes with growth and may impact final height (FH). AIM: To investigate the impact of ePS and GAH on FH in trans boys and trans girls. METHODS: Retrospective study, including 10 trans boys and 22 trans girls at FH. Bone age (BA) was determined at the start of ePS and at the start of GAH according to Greulich and Pyle; predicted adult height (PAH) was calculated according to Bayley and Pinneau's tables; target height (TH) was calculated as adjusted mean of maternal and paternal height. Target height, PAH, and BA were determined according to sex registered at birth (SRAB) and experienced gender (EG). RESULTS: The age at the start of PS was 12.37 ± 0.74 years in trans boys and 13.10 ± 1.12 years in trans girls. Total height gain since the start of ePS in trans boys was 14.62 ± 4.08 cm, with 70% achieved before the start of GAH. In trans girls, it was 20.68 ± 7.66 cm, with 61% achieved before GAH. Target height for SRAB was the most accurate predictor for FH in both trans boys and girls: the difference with FH was 1.57 cm ± 3.1 (P = .168) and -0.98 cm ± 4.17 (P = .319), respectively. Also the difference between FH and PAH at the start of PS for SRAB was nonsignificant in both trans boys and girls (2.62 cm ± 3.79, P = .056 and -2.35 cm ± 5.2, P = .051, respectively). CONCLUSION: Early puberty suppression and GAH do not impact FH, supporting the safety of the treatment; however, trans adolescents achieve a FH in line with SRAB, rather than EG.

RESUMEN

Gender-affirming hormone therapy (GAHT) can help transgender and/or gender diverse (TGD) individuals achieve emobidment goals that align with their transition needs. Clinical evidence from estradiol (E)-GAHT patients indicate widespread changes in tissues sensitive to E and testosterone (T), particularly in the reproductive system. Notably, E-GAHTs effects on hormones and reproduction vary greatly between patients. With the goal of informing clinical research and practice for TGD individuals taking E, this study examines intact male mice implanted with capsules containing one of three different E doses (low 1.25 mg; mid 2.5 mg; high 5 mg), or a blank control capsule. All E-GAHT doses suppress T and follicle stimulating hormone levels while elevating E levels. Only the high E-GAHT dose significantly supresses luteinizing hormone levels. All E-GAHT doses affect epididymis tubule size similarly while seminiferous tubule morphology and bladder weight changes are dose-dependent. E-GAHT does not alter the presence of mature sperm, though E-exposed sperm have altered motility. These data represent the first evidence that mouse models offer an effective tool to understand E-GAHTs impact on reproductive health and the dose-dependent effects of this model permit examinations of diverse patient outcomes.

RESUMEN

Transgender and nonbinary people with female birth sex may utilize testosterone therapy for masculinization. Individuals interested in reproduction using their own gametes should be offered fertility preservation prior to starting testosterone. However, logistical and practical barriers prevent many from accessing fertility preservation options prior to starting testosterone. Some of these transmasculine and nonbinary individuals may later become interested in carrying a pregnancy or using their oocytes for reproduction after being on testosterone. Many questions remain about the reproductive impact of long-term masculinizing testosterone therapy. Emerging literature has documented pregnancies and successful assisted reproduction for some people after taking testosterone, but it is not known whether individuals can expect these successful outcomes. Testosterone appears to impact the reproductive tract, including the ovaries, uterus, and fallopian tubes, but the reversibility and functional impact of these changes also remain unclear. A greater understanding of the impact of masculinizing testosterone on reproductive capacity remains a priority area for future research.

RESUMEN

BACKGROUND: Gender incongruence (GI) is a term used to describe a marked and persistent incompatibility between the sex assigned at birth (SAAB) and the experienced gender. Some persons presenting with GI experience a severe psychological distress defined as gender dysphoria (GD).. Although the prevalence of GI is probably underestimated, recently a great increase in numbers of transgender and gender diverse (TGD) youths presenting at the gender clinics has been registered. After a careful multidisciplinary evaluation and upon acquisition of informed consent from the youth and the legal guardian(s), puberty suppression can be started in TGD youths, followed by the addition of gender affirming hormones (GAH) by the age of 16 years. Although Italian specific guidelines are available, their application is often complex because of (among other reasons) lack of specialized centers and healthcare professional with experience in the field and the regional differences within the Italian healthcare system. MAIN BODY: To investigate the care offered to TGD youths across Italy, we proposed a survey of 20 questions to the directors of the 32 Italian Centers of pediatric endocrinology participating to the Study Group on Growth and Puberty of the Italian Society of Pediatric Endocrinology (ISPED). Eighteen pediatric endocrinologists representative of 16 different centers belonging to 11 different regions responded to the survey. In the large majority of centers TGD youths are taken in charge between the age of 12 and 18 years and at least three healthcare professional are involved. Most of Italian pediatric endocrinologists follow only a very limited number of TGD youths and reference centers for TGD youths are lacking. CONCLUSION: There is an urgent need for gender clinics (homogeneously distributed on the national territory) where TGD youths can access high standard care.

RESUMEN

Purpose: Few studies have assessed the effects of hormonal treatments such as gonadotropin-releasing hormone agonists (GnRHa) and gender-affirming hormones (GAH) on mental health outcomes in clinically referred gender-diverse young people from a younger age. Where this research has been conducted, findings have been mixed. This study investigated a cohort of young people before treatment, 1 year into GnRHa, and 1 year into GAH treatment to understand psychological and behavioral impacts over time. Methods: Thirty-eight young people (28 assigned female and 10 assigned male) referred to endocrinology, younger than 15 years at/beyond Tanner stage two, who received GnRHa followed by GAH treatment, were assessed in a retrospective analysis study. Young people completed the Youth Self Report (YSR), the Body Image Scale, and the Utrecht Gender Dysphoria Scale, while caregivers completed the Child Behavior Checklist (CBCL) and the Social Responsiveness Scale-2 at all time points. Results: Dissatisfaction with primary sexual characteristics (p = 0.02), gender dysphoria (p = 0.01), and social motivation (p = 0.04) improved significantly over time. Self-harm and suicidality also showed a general decrease. Caregivers reported a significant reduction in internalizing (p = 0.03) behaviors on the CBCL after GnRHa. Other subcategories of the YSR and CBCL were within normal ranges with no significant difference (p > 0.05). Conclusion: These findings demonstrate some improvements in psychological and behavioral outcomes in young people concurrently receiving psychosocial support and hormone treatment. Future research with larger and more diverse samples is warranted to further understand generalizability.

RESUMEN

Changes in gonadal hormones during puberty are thought to potentiate adolescents' social re-orientation away from caregivers and towards peers. This study investigated the effect of testosterone on neural processing of emotional (vocal) stimuli by unfamiliar peers vs. parents, in transgender boys receiving exogenous testosterone as a gender-affirming hormone (GAH+) or not (GAH-). During fMRI, youth heard angry and happy vocal expressions spoken by their caregiver and an unfamiliar teenager. Youth also self-reported on closeness with friends and parents. Whole-brain analyses (controlling for age) revealed that GAH+ youth showed blunted neural response to caregivers' angry voices-and heightened response to unfamiliar teenage angry voices-in the anterior cingulate cortex. This pattern was reversed in GAH- youth, who also showed greater response to happy unfamiliar teenager vs. happy caregiver voices in this region. Blunted ACC response to angry caregiver voices-a pattern characteristic of GAH+ youth-was associated with greater relative closeness with friends over parents, which could index more "advanced" social re-orientation. Consistent with models of adolescent neurodevelopment, increases in testosterone during adolescence may shift the valuation of caregiver vs. peer emotional cues in a brain region associated with processing affective information.

RESUMEN

Approximately 50% of transmasculine people use testosterone for gender affirmation, yet very little is known about the effects of testosterone on future reproductive capacity. Moreover, there are no data to guide fertility specialists on how to manage testosterone leading up to or during ovarian stimulation. Most clinics require cessation of testosterone prior to ovarian stimulation in this setting of no data; however, the current literature does suggest a potential increase in dysphoria with cessation of testosterone and during stimulation. This divergence begs the question of whether clinicians may be doing more harm than good by enacting this requirement. Here, we present two cases of transmasculine individuals who were on testosterone prior to stimulation and maintained their testosterone dosage throughout stimulation as proof of concept, followed by a discussion of current clinical practice and providing some rationale to support continuation of testosterone throughout stimulation.

RESUMEN

Increasing numbers of transgender individuals are presenting for gender-affirming medical care. For trans women, gender-affirming hormone therapy (GAHT) promotes feminization but also inhibits spermatogenesis. There is a common untested assumption that this inhibition is permanent, resulting in infertility. In this longitudinal study, we report the recovery of viable spermatozoa in nine trans women who stopped GAHT for reproductive purposes. Our preliminary findings suggest that the negative impact of GAHT on spermatogenesis can be reversed, casting doubt on previous claims that GAHT in trans women inevitably leads to permanent infertility. Larger studies are needed to confirm our findings, which have implications not only for fertility counseling and the reproductive options of transgender individuals but also efforts to restrict access to GAHT based on fertility grounds.

RESUMEN

PURPOSE: Gender-affirming hormones and/or surgeries seeking to change the body can have potentially lasting effects. Changes in requests for these therapies among gender-diverse youth are not well-understood. The study aim is to characterize factors associated with shifts in gender-related medical requests. METHODS: This mixed-methods study used retrospective chart review and qualitative interviews with clinicians. Of 130 youth receiving clinical gender care at Children's National Hospital, 68 met inclusion criteria. Qualitative interview analysis was performed to identify patterns and themes around shifts in gender-related medical requests over time. Statistical analysis employed chi-square and t-tests to compare characteristics in the shift versus no-shift groups and kappa statistics to calculate qualitative coding agreement. RESULTS: Of the 68 youth followed over time (mean age 15.11 years, 47% autistic, 22% nonbinary), 20 (29%) reported a shift in request. No significant differences were found by age, autism status, or designated sex at birth. More youth with shifts were nonbinary (p = .012). Six shift profiles were identified from qualitative interviews with excellent reliability (κ = 0.865). Four of the profiles reflect shifts in request prior to starting treatment (85% sample); two involved shifts after commencing treatment (15%). The most common profile reflected a medical request that was made, withdrawn, and re-requested (45%). DISCUSSION: Shifts in gender-affirming medical requests by gender-diverse youth may not be uncommon during the adolescent's gender discernment process, and may more likely occur among nonbinary youth. Many individuals who experience shifts away from medical treatment may later resume the request.

RESUMEN

BACKGROUND: Past studies have demonstrated better mental health and well-being among transgender youth who had accessed gender-affirming care. However, few existing studies have assessed unmet need for gender-affirming care as a social determinant of mental health inequities. METHODS: Data on unmet need for gender-affirming care, distress and suicidality were analysed from the 2018 Counting Ourselves nationwide community-based survey of transgender people in Aotearoa/New Zealand. Associations between unmet need for gender-affirming care and mental health indicators were tested for transgender youth within the sample (aged 14-26 years; n = 608; Mage = 20.5). RESULTS: Transgender youth reported unmet needs ranging from 42% for gender-affirming hormone to 100% for feminizing surgeries and voice surgeries. Overall unmet need for gender-affirming care was associated with worse mental health. Trans men with an unmet need for chest reconstruction (84%) scored an average of 7.13 points higher on the K10 Psychological Distress Scale relative to those whose need had been met. Participants reporting unmet need for hormones (42%) had twice the odds (adjusted odds ratios = 2.01; CI = 1.02-3.98) of having attempted suicide in the last 12 months. CONCLUSIONS: Dismantling barriers to accessing gender-affirming care could play a crucial role in reducing mental health inequities faced by transgender youth.

RESUMEN

While individuals have demonstrated gender diversity throughout history, the use of medication and/or surgery to bring a person's physical sex characteristics into alignment with their gender identity is relatively recent, with origins in the first half of the 20th century. Adolescent gender-affirming care, however, did not emerge until the late 20th century and has been built upon pioneering work from the Netherlands, first published in 1998. Since that time, evolving protocols for gender-diverse adolescents have been incorporated into clinical practice guidelines and standards of care published by the Endocrine Society and World Professional Association for Transgender Health, respectively, and have been endorsed by major medical and mental health professional societies around the world. In addition, in recent decades, evidence has continued to emerge supporting the concept that gender identity is not simply a psychosocial construct but likely reflects a complex interplay of biological, environmental, and cultural factors. Notably, however, while there has been increased acceptance of gender diversity in some parts of the world, transgender adolescents and those who provide them with gender-affirming medical care, particularly in the USA, have been caught in the crosshairs of a culture war, with the risk of preventing access to care that published studies have indicated may be lifesaving. Despite such challenges and barriers to care, currently available evidence supports the benefits of an interdisciplinary model of gender-affirming medical care for transgender/gender-diverse adolescents. Further long-term safety and efficacy studies are needed to optimize such care.
