Gender Dysphoria in Adults

Development of Gender Non-Contentedness During Adolescence and Early Adulthood

Adolescence is an important period for the development of gender identity. We studied the development of gender non-contentedness, i.e., unhappiness with being the gender aligned with one's sex, from early adolescence to young adulthood, and its association with self-concept, behavioral and emotional problems, and adult sexual orientation. Participants were 2772 adolescents (53% male) from the Tracking Adolescents' Individual Lives Survey population and clinical cohort. Data from six waves were included (ages 11-26). Gender non-contentedness was assessed with the item "I wish to be of the opposite sex" from the Youth and Adult Self-Report at all six waves. Behavioral and emotional problems were measured by total scores of these scales at all six waves. Self-concept was assessed at age 11 using the Global Self-Worth and Physical Appearance subscales of the Self-Perception Profile for Children. Sexual orientation was assessed at age 22 by self-report. In early adolescence, 11% of participants reported gender non-contentedness. The prevalence decreased with age and was 4% at the last follow-up (around age 26). Three developmental trajectories of gender non-contentedness were identified: no gender non-contentedness (78%), decreasing gender non-contentedness (19%), and increasing gender non-contentedness (2%). Individuals with an increasing gender non-contentedness more often were female and both an increasing and decreasing trajectory were associated with a lower global self-worth, more behavioral and emotional problems, and a non-heterosexual sexual orientation. Gender non-contentedness, while being relatively common during early adolescence, in general decreases with age and appears to be associated with a poorer self-concept and mental health throughout development.

The effects of gender-affirming hormone therapy and mastectomy on psychopathology, body image, and quality of life in adults with gender dysphoria who were assigned female at birth

PURPOSE

Individuals with gender dysphoria (GD) may request hormone therapy and various surgical operations to change their physical characteristics. The present study aimed to investigate the effects of two treatments, mastectomy and gender-affirming hormone therapy (GAHT), on adults with GD who were assigned female at birth (GD AFAB).

METHODS

In this cross-sectional study, we gathered data from a total of 269 individuals in three groups: (a) untreated group (n = 121), (b) GAHT group (n = 84) who had been receiving treatment for at least 6 months, and (c) GAHT-MAST group (n = 64) who had been using GAHT for at least 6 months and had undergone mastectomy at least 3 months prior. All participants were asked to complete the Symptom Checklist-90-Revised (SCL-90-R), the Body Uneasiness Test (BUT), and the World Health Organization's Quality of Life Questionnaire- Brief Form, Turkish Version (WHOQOL-BREF-Tr).

RESULTS

We found that individuals in the untreated group had higher psychopathological symptoms and body uneasiness scores, and lower quality of life scores compared to both GAHT and GAHT-MAST groups. There was no difference in psychopathology between the GAHT-MAST group and the GAHT group, but body uneasiness scores were lower, and quality of life scores were higher in the GAHT-MAST group.

CONCLUSION

Our study suggests that individuals receiving GAHT improved mental health, body satisfaction, and overall quality of life. Combining mastectomy with GAHT may further enhance these benefits.

Effect of gender identity on the association between gender dysphoria and suicidality via appearance anxiety among transgender and gender-diverse young people: moderated mediation study

BACKGROUND

Gender dysphoria is associated with suicidality among transgender and gender-diverse (TGD) people. Gender dysphoria also results in a stress on appearance.

AIMS

The objectives of this study were to examine: (a) whether appearance anxiety mediates the effect of gender dysphoria on suicidality; and (b) whether gender identity moderates the mediating effect of appearance anxiety.

METHOD

A total of 117 769 college and university students were recruited in this cross-sectional study from Jilin Province, China. After screening based on participants' gender identity, 2352 TGD young people (aged from 15 to 25 years) were divided into three subgroups: female to male (FTM), male to female (MTF) and non-binary. Self-report inventories measured gender dysphoria, suicidality and appearance anxiety. A structural equation model was run to examine the relationships among TGD gender identity, gender dysphoria, appearance anxiety and suicidality.

RESULTS

Among TGD young people, gender dysphoria was significantly positively associated with suicidality (β = 0.15, 95% CI = 0.11-0.18, P < 0.001). Appearance anxiety partially mediated the association between gender dysphoria and suicidality (β = 0.07, 95% CI = 0.05-0.08, P < 0.001). Gender identity moderated the mediating effects: compared with individuals with FTM identity, among those with MTF and non-binary identities, gender dysphoria showed stronger positive effects on appearance anxiety, and appearance anxiety showed greater effects in mediating the association between gender dysphoria and suicidality.

CONCLUSIONS

Among TGD young people, gender dysphoria is significantly associated with suicidality via appearance anxiety, with gender identity moderating the mediating effects. Diverse treatments should consider the heterogeneity of TGD subgroups, with the aim of limiting the tendency of gender dysphoria to trigger appearance anxiety, thus further buffering against the risk of suicide.

External Minority Stress, Gender Dysphoria, and Capability for Suicide Among Transgender Adults: A Daily Diary Study

This study analyzed whether external gender-related minority stress (i.e., discrimination, rejection, and violence) and gender dysphoria contribute to same-day and next-day acquired capability for suicide (ACS) in a sample of transgender adults residing in the southeastern United States. A sample of transgender participants (n = 38, 84.2% White, average age = 28.6 years) residing in the southeastern United States completed daily surveys on discrimination, rejection, violence, gender dysphoria, and ACS over 30 days (n = 836 of the 1,140 surveys sent out were completed). External minority stress (i.e., rejection, discrimination, and violence) was very common in this sample. External minority stress experiences were reported on 16% of the completed daily surveys, and 68% of the sample reported experiencing such stress at least once over the 30-day study period. Similarly, gender dysphoria occurred on 37.2% of the completed days and was experienced on at least 1 day by 78.9% of the participants over the 30-day survey period. Multilevel modeling showed daily experiences of discrimination and rejection, but not gender dysphoria, were positively associated with same-day ACS. Violence trended toward significance in correlating with same-day capability for suicide. Neither external minority stress nor gender dysphoria were associated with next-day ACS while controlling for acquired capability reported on the previous day. These preliminary data support proximal associations of external gender minority stress with same-day, but not next-day, ACS. Findings from this study advance understanding of how anti-transgender discrimination and violence contribute to increased capability for suicide in a population at increased risk for suicide.

Age of Realization and Disclosure of Gender Identity Among Transgender Adults

PURPOSE

The "rapid-onset gender dysphoria" (ROGD) hypothesis theorized, based on a parent-report survey, a distinct and more transient form of gender dysphoria in which individuals purportedly come to understand themselves as transgender and/or gender diverse (TGD) suddenly during adolescence. This study evaluated components of ROGD by (1) estimating the prevalence among TGD adults of first realizing one's TGD identity after childhood (i.e., after the onset of puberty), and (2) assessing the median time between realizing one's gender identity and disclosing this to someone else.

METHODS

We conducted a secondary analysis of the 2015 US Transgender Survey, a survey of 27,715 TGD adults in the United States. Participants were asked the age at which they first realized their gender identity was different than societal expectations based on their sex assigned at birth and grouped by "childhood realization" (ages ≤ 10 years) and "later realization" (ages > 10). They were also asked the age at which they first shared their gender identity with another person.

RESULTS

Of 27,497 participants, 40.8% reported "later realization" of TGD identities. Within the "childhood realization" group, the median age of sharing one's gender identity with another person was 20. In this group, the median time between realization of one's gender identity and sharing this with another person was 14 years.

DISCUSSION

A substantial proportion of TGD adults reported realizing their gender identity was different from societal expectations based on their sex assigned at birth during adolescence or later. Several years typically elapsed between participants' TGD identity realization and sharing this with another person. The results of this study do not support the ROGD hypothesis.

Loneliness and Social Isolation among Transgender and Gender Diverse People

Here, we report the prevalence of loneliness and social isolation and investigate the levels of loneliness and social isolation among transgender and gender diverse people using cross-sectional data from the HH-TPCHIGV study. Using the De Jong Gierveld tool, we assess loneliness, using the Bude and Lantermann tool, we assess perceived social isolation and using the Lubben Social Network Scale, we assess objective social isolation. The prevalence rate of loneliness was 83.3% (perceived social isolation: 77.7%; objective social isolation: 34.4%). Regressions revealed that favorable outcomes (i.e., lower loneliness levels, lower perceived social isolation, and lower objective social isolation) were consistently associated with higher school education. Beyond that, we identify an association between particularly poor health-related factors and higher loneliness and objective social isolation levels. We also report that unemployment was significantly associated with higher levels of perceived social isolation. In conclusion, we show high prevalence rates of loneliness and social isolation among transgender and gender diverse people. Additionally, important correlates (e.g., education, health-related factors, or unemployment) were identified. Such knowledge may provide help to address transgender and gender diverse people at risk for loneliness and social isolation.

The Impact of Stressful Life Events on Suicidal Ideation in Gender Dysphoria: A Moderator Effect of Perceived Social Support

Factors associated with suicidal ideation in the gender dysphoria population are not completely understood. This high-risk population is more likely to suffer stressful events such as assault or employment discrimination. This study aimed to determine the association of stressful events and social support on suicidal ideation in gender dysphoria and to analyze the moderator effect of social support in relation to stressful events and suicidal ideation. A cross-sectional design was used in a clinical sample attending a public gender identity unit in Spain that consisted of 204 individuals (51.7% birth-assigned males and 48.3% birth-assigned females), aged between 13 and 59 (M = 27.95 years, SD = 9.58). A Structured Clinical Interview, a list of 16 stressful events, and a functional social support questionnaire (Duke-UNC-11) were used during the initial visits to the unit. The data were collected between 2011 and 2012. A total of 50.1% of the sample have had suicidal ideation. The following stressful events were associated with suicidal ideation: homelessness, eviction from home, and having suffered from physical or verbal aggression. Also, there was an inverse relation between perceived social support and suicidal ideation. There was a statistically significant interaction between a specific stressful event (eviction) and perceived social support. The study suggests that the promotion of safer environments could be related to lower suicidal ideation and that networks that provide social support could buffer the association between specific stressful events and suicidal ideation.

Is Social Gender Transition Associated with Mental Health Status in Children and Adolescents with Gender Dysphoria?

Social gender transition is an increasingly accepted intervention for gender variant children and adolescents. To date, there is scant literature comparing the mental health of children and adolescents diagnosed with gender dysphoria who have socially transitioned versus those who are still living in their birth-assigned gender. We examined the mental health of children and adolescents referred to the Gender Identity Development Service (GIDS), a specialist clinic in London, UK, who had socially transitioned (i.e., were living in their affirmed gender and/or had changed their name) versus those who had not socially transitioned. Referrals to the GIDS were aged 4-17 years. We assessed mental health correlates of living in one's affirmed gender among 288 children and adolescents (208 birth-assigned female; 210 socially transitioned) and of name change in 357 children and adolescents (253 birth-assigned female; 214 name change). The presence or absence of mood and anxiety difficulties and past suicide attempts were clinician rated. Living in role and name change were more prevalent in birth-assigned females versus birth-assigned males. Overall, there were no significant effects of social transition or name change on mental health status. These findings identify the need for more research to understand how social transition influences mental health, including longitudinal studies that allow for more confident inferences to be made regarding the relationship between social transition and mental health in young people with gender dysphoria.

Empirically supported affirmative psychological interventions for transgender and non-binary youth and adults: A systematic review

Research suggests that transgender and non-binary (TGNB) individuals experience lower levels of psychological well-being than the general population. Although practice recommendations and guidelines exist, there is a paucity of studies evaluating the effects of psychological interventions on this group. This systematic review aimed to synthesize and analyze existing empirical affirmative psychological interventions for TGNB individuals to assess their efficacy. Eight databases (PubMed, Web of Science, PsycINFO, Scopus, LILACS, Cochrane, ProQuest, Google Scholar) were searched from January 2010 to June 2022 to identify relevant studies. Included studies needed to be randomized controlled trials, quasi-experimental, or uncontrolled pre-post. Twenty-two articles were included, of which eight had TGNB participants only, two had mixed samples with separated outcome data for TGNB participants, and 12 had mixed samples with no disaggregated data. Experimental designs, participant samples, assessed variables, and type of interventions varied widely across studies, thus preventing comparisons. Overall results suggest improvements in psychological distress, depression, anxiety, suicidality, substance-related risk behaviors, coping skills/emotion regulation, stress appraisal, self-esteem, self-acceptance, social support, minority stress, resilience, hope, positive identity, and identity acceptance, although conclusions are limited by moderate-to-high risk of bias. Future research should implement more consistent and rigorous methodological designs to assess and compare intervention efficacy.

Suicide-Related Outcomes Following Gender-Affirming Treatment: A Review

Gender-affirming treatment remains a topic of controversy; of particular concern is whether gender-affirming treatment reduces suicidality. A narrative review was undertaken evaluating suicide-related outcomes following gender-affirming surgery, hormones, and/or puberty blockers. Of the 23 studies that met the inclusion criteria, the majority indicated a reduction in suicidality following gender-affirming treatment; however, the literature to date suffers from a lack of methodological rigor that increases the risk of type I error. There is a need for continued research in suicidality outcomes following gender-affirming treatment that adequately controls for the presence of psychiatric comorbidity and treatment, substance use, and other suicide risk-enhancing and reducing factors. There is also a need for future systematic reviews given the inherent limitations of a narrative review. There may be implications on the informed consent process of gender-affirming treatment given the current lack of methodological robustness of the literature reviewed.

Gender dysphoria: An overview for orthodontists

Among non-gender conforming populations, there is a subgroup of individuals who experience significant distress associated with their gender incongruity, commonly referred to as gender dysphoria (GD). In the UK, there is a recognised pathway for individuals experiencing GD. This has traditionally been initiated by a referral to the Gender Identity Development Service (GIDS) for children and adolescents or to a Gender Identity Clinic (GIC) for adults. This pathway can potentially involve several specialties and treatment modalities, including the prescription of various hormones. It is important for orthodontists to have an understanding of this field, as well as the potential treatment modalities, so that they can support this often marginalised patient group. Inherent differences between male and female facial features may also lead patients with GD to present to orthodontists, wishing to change their facial appearance. This article highlights the current national pathway for GD and the orthodontic considerations for these individuals.

Barriers and Challenges in Caring for Transgender People: Implications for Clinical Practice and the Experience From a Specialized Center

Background: Transgender people often experience social exclusion and transphobic attitudes, which have an adverse impact on their socioeconomic life and health status. Within health services, -discriminatory practices and mistreatment derive from the lack of cultural competence by -healthcare providers. Objective: This article features existing barriers in the provision of healthcare to transgender populations and suggests approaches to manage the relevant challenges. Methods: A thorough review of the literature was performed, and the operation of a specialized unit wass presented. Results: Health professionals are often unskilled or unwilling to offer transgender care, while most healthcare service institutions do not offer specialized treatments. Incomplete health insurance coverage and shortages of personal income impede trans individuals' access to healthcare. Certain practices and policies are needed for scientifically and culturally competent services. Conclusions: The social vulnerability and the unique health needs of transgender persons urgently call for accessible and effective care for gender minority individuals. The integration of gender identity issues into continuous medical and nursing education is a key component of transgender-friendly care. Implications for Nursing: The integration of diversity as a core value in health services, the ability of health personnel to deliver transgender care, and the provision of insurance coverage solely based on medical needs are necessary steps to achieve social justice in healthcare.

Differentiating protective factors for transgender individuals who experience suicidality: The role of optimism as a mediator

As a result of experiencing oppression-based stressors and trauma, suicide rates for lesbian, gay, bisexual and transgender (LGBTQ+) individuals are much higher than in the general population, and for trans and gender non-binary (TGNB) individuals specifically, rates of suicidality are even higher. To best understand how to engage in suicide prevention and intervention efforts for TGNB individuals, it is therefore crucial to understand factors that may mitigate suicidality for TGNB individuals. The purpose of this study was to examine the relationship between protective factors-body acceptance, optimism, social support and pride-and suicidality for TGNB adults. A total of 139 TGNB participants completed an online survey about suicidal behaviours, transgender-specific risk factors and transgender-specific protective factors. High rates of suicidality were observed in our sample. Initial results suggested that only optimism was inversely significantly related to suicidality. Given that optimism, which suggests a belief in a better future, has been found in previous studies to buffer the effects of deleterious stressors, optimism was also examined as a mediator between body acceptance (a key feature of gender dysphoria) and suicidality. Results suggested that optimism did mediate the relationship between body acceptance and suicidality. Optimism appears to be an important protective factor against suicidality for TGNB individuals and thus a potentially important target of intervention.

The metabolic effects of hormonal treatment in transgender males: Safety of the testosterone gender-affirming therapy

BACKGROUND

Gender dysphoria is characterised by a sense of distress because of discordance between the self-perception of gender identity and the assigned sex. Hormonal treatment of transgender males uses testosterone to induce and preserve masculinisation.

OBJECTIVE

The study investigated the safety of testosterone therapy in transgender males.

METHODS

The present study used a retrospective file review of transgender male subjects who were treated with testosterone (initially transdermal testosterone gel and subsequently parenteral testosterone undecanoate) for at least 18 months and had subsequently achieved a serum testosterone level within the normal range of cisgender male counterparts. Changes in somatometric data and blood biomarkers were investigated.

RESULTS

The mean testosterone serum levels after approximately 18 months of treatment were about 545 ng/dL (SD ± 94 ng/dL). There was a statistically significant rise in body mass index (𝜒d = +1.23 kg/m2) with a reduction in blood glucose (𝜒d = -5.33 mg/dL) as well as statistically significant increases in aspartate transaminase (𝜒d = +4.3 U/L), haemoglobin (𝜒d = +1.72 g/dL), and haematocrit (𝜒d = +4.76%). In contrast, there were no significant changes in the lipidaemic profile of the subjects.

CONCLUSIONS

Treatment with testosterone is routinely used for the promotion of virilising physical changes in transgender males. However, the likelihood of adverse effects of continuous treatment is still unclear. This study contributed to the notion that achieving testosterone levels within the target range is a prerequisite for the safety of the gender-affirming treatment.

"I'm a transgender man… I have to quit smoking for treatment and surgery": Describing the experience of a Latino transgender man during his attempt to quit smoking

OBJECTIVE

To describe the experience of a Latino transgender man during his attempt to quit smoking using a text messaging intervention.

METHODS

A Latino transgender man enrolled in a smoking cessation randomized controlled trial for Latino smokers. The participant was randomized to Decídetexto, a smoking cessation mobile intervention. The participant received a 24-week text messaging intervention. We assessed text messaging interactivity with the program, satisfaction, and self-reported abstinence at Week 12 and Month 6.

RESULTS

During the 24-week intervention period, the participant sent a total of 287 text messages to the program. When analyzing the content of the text messages sent by the participants, four important themes were identified: 1) gender identity, 2) low social support, 3) stressors (e.g., gender dysphoria), and 4) gender affirmation surgery as a reason to quit smoking. At both Week 12 and Month 6, the participant reported being extremely satisfied with the intervention and self-reported cigarette use.

CONCLUSION

A smoking cessation mobile intervention generated high satisfaction and frequent interactivity among a Latino transgender man. This case report provides important insights into the experience of one Latino transgender man during his attempt to quit smoking. There is an urgent need to develop or adapt existing smoking cessation interventions to better meet the needs of transgender people.

Is Conservative Religiousness Inherently Associated with Poorer Health for Sexual Minorities?

Results of path analysis involving sexual minority participants (N = 1317) from diverse sociopolitical contexts revealed health outcomes to be associated with internalized homonegativity and the resolution of conflict between religious and sexual minority identities. Contrary to expectations, several markers of religiousness were not directly associated with either improved or worsened health outcomes for depression or anxiety. However, religious activity moderated the influence of internalized homonegativity (IH) on depression such that IH was less strongly related to depression among individuals who frequently attended religious services than among individuals who infrequently attended religious services. These findings have special salience for advancing a more accurate understanding of conservatively religious sexual minorities and directing culturally sensitive research, clinical services, and public policy.

Prevalence of diagnosed eating disorders in US transgender adults and youth in insurance claims

OBJECTIVE

We estimated the prevalence of diagnosed eating disorders, overall and by select demographics, among commercially insured individuals identified as transgender in a national claims database.

METHODS

From the 2018 IBM® MarketScan® Commercial Database, there were 10,415 people identifiable as transgender based on International Classification of Disease (ICD-10) codes and procedure codes, specific to gender-affirming care, from inpatient and outpatient claims. Eating disorders were identified from ICD-10 codes and included anorexia nervosa, bulimia nervosa, binge eating disorder, eating disorder not otherwise specified, avoidant restrictive feeding and intake disorder, and other specified feeding and eating disorders. We estimated the prevalence of specific eating disorders diagnoses by selecting patient characteristics.

RESULTS

Of individuals receiving some form of gender-affirming care, 2.43% (95% confidence interval: 2.14%-2.74%) were diagnosed with an eating disorder: 0.84% anorexia nervosa, 0.36% bulimia nervosa, 0.36% binge eating disorder, 0.15% avoidant restrictive feeding and intake disorder, 0.41% other specified feeding and eating disorders, and 1.37% with an unspecified eating disorder. Among transgender-identifiable patients aged 12-15 years, 5.60% had an eating disorder diagnosis, whereas 0.52% had an eating disorder diagnosis in patients aged 45-64 years.

DISCUSSION

In patients identifiable as transgender, with receipt of gender-affirming care, the prevalence of diagnosed eating disorders was low compared to extant self-reported data for eating disorder diagnosis in transgender individuals. Among this population, eating disorders were highest in adolescents and young adults. Clinically verified prevalence estimates for eating disorder diagnosis in transgender people with a history of gender-affirming care warrant further investigation.

PUBLIC SIGNIFICANCE

The present study aims to provide clinically validated, contemporary prevalence estimates for diagnosed eating disorders among a medically affirmed population of transgender adults and children in the United States. We report low prevalence of having any eating disorder relative to prevalence estimates reported in prior literature without clinical validation. These findings may be explained by access to affirming care and medical care generally.

Enhancing Gender

Transgender healthcare faces a dilemma. On the one hand, access to certain medical interventions, including hormone treatments or surgeries, where desired, may be beneficial or even vital for some gender dysphoric trans people. But on the other hand, access to medical interventions typically requires a diagnosis, which, in turn, seems to imply the existence of a pathological state-something that many transgender people reject as a false and stigmatizing characterization of their experience or identity. In this paper we argue that developments from the human enhancement debate can help clarify or resolve some of the conceptual and ethical entanglements arising from the apparent conflict between seeking medicine while not necessarily suffering from a pathology or disorder. Specifically, we focus on the welfarist account of human enhancement and argue it can provide a useful conceptual framework for thinking about some of the more contentious disagreements about access to transgender healthcare services.

Autism Spectrum Disorder and Gender Dysphoria/Incongruence. A systematic Literature Review and Meta-Analysis

The suggested overlap between autism spectrum disorder (ASD) and gender dysphoria/incongruence (GD/GI) has been much disputed. This review showed a relationship between ASD traits and GD feelings in the general population and a high prevalence of GD/GI in ASD. Our meta-analyses revealed that the pooled estimate of the prevalence of ASD diagnoses in GD/GI people was 11% (p < .001) and the overall effect size of the difference in ASD traits between GD/GI and control people was significant (g = 0.67, p < .001). Heterogeneity was high in both meta-analyses. We demonstrated that the chances that there is not a link between ASD and GD/GI are negligible, yet the size of it needs further investigation.

Should chromosomal analysis be performed routinely during the baseline evaluation of the gender affirmation process? The outcomes of a large cohort of gender dysphoric individuals

The role of genetics in the etiology of gender dysphoria (GD) is an important yet understudied area. Yet whether genetic analysis should be carried out during the gender affirmation process at all is a matter of debate. This study aims to evaluate the cytogenetic and molecular genetic findings of individuals with GD. We retrospectively reviewed the medical records of individuals with GD who were followed up in a tertiary clinic. After the exclusion criteria were applied, the study sample consisted of 918 individuals with GD; 691 of whom had female-to-male (FtM) and 227 male-to-female (MtF) GD. The cytogenetic analysis revealed that 223 out of 227 (98.2%) individuals with MtF GD had the 46,XY karyotype, while 683 out of 691 (98.8%) individuals with FtM GD had the 46,XX karyotype. In the Y chromosome microdeletion analysis, azospermic factor c (AZFc) deletion was detected in only two individuals with MtF GD. Our findings suggest that there are few chromosomal abnormalities in individuals with GD. Thus, this research calls into question both the role of chromosomal abnormalities in GD etiology and why the application of chromosomal analysis is in Turkey a routine part of the baseline evaluation of GD.

Gray matter volume differences between transgender men and cisgender women: A voxel-based morphometry study

OBJECTIVE

Gender dysphoria (GD) is characterized by distress due to inconsistency between gender identity and biological sex. Individuals with GD often desire to be the other gender, which is called transgender. Although altered brain volumes in transgender people, particularly transgender women, have been reported, the particular brain regions have been inconsistent among studies. This study aimed to investigate neuroanatomical differences in transgender men without physical interventions.

METHOD

T1-weighted magnetic resonance images (MRIs) were acquired in 21 transgender men and 21 cisgender women matched for biological sex and age. Whole-brain comparisons using voxel-based morphometry (VBM) were performed to identify gray matter volume (GMV) differences between transgender men and cisgender women.

RESULTS

Transgender men showed greater GMV in the right posterior cingulate gyrus (P_FWE-corr = 3.06×10^-6) and the left occipital pole (P_FWE-corr = 0.017) and lower GMV in the left middle temporal gyrus (P_FWE-corr = 0.017) than cisgender women. Even after including serum sex hormone levels as covariates, the posterior cingulate gyrus was still significant (P_FWE-corr < 0.05). In contrast, the occipital pole and the middle temporal gyrus were not significant after controlling for the sex hormone levels (P_FWE-corr > 0.05), especially affected by testosterone but not estradiol.

CONCLUSION

These findings suggest that transgender men have altered brain structure. We suggest that larger posterior midline structures may contribute to sensitivity to self-referential processing through altered visual perception in transgender people.

Complex psychiatric comorbidities in Thai trans women: A case series

Trans women (TW) have a high prevalence of poor mental health. Gender-affirming treatments could reduce distress regarding their gender incongruity. However, psychiatric comorbidities might complicate the management or even confirmation of being transgender. We reported three TW with complex mental illnesses, including anxiety disorder with cultural explanation, neurodevelopmental disorders with cross-dressing, and severe personality disorder accompanied by major depression. All cases received both psychiatric and gender-affirming treatments, which demonstrated promising outcomes. Along with gender dysphoria (GD), psychiatric comorbidities also altered these TW's identity and manifestations. Recognition of such conditions would be beneficial in providing care for all TW, both with and without GD.

Suicidality in clinic-referred transgender adolescents

Gender and sexually diverse adolescents have been reported to be at an elevated risk for suicidal thoughts and behaviors. For transgender adolescents, there has been variation in source of ascertainment and how suicidality was measured, including the time-frame (e.g., past 6 months, lifetime). In studies of clinic-referred samples of transgender adolescents, none utilized any type of comparison or control group. The present study examined suicidality in transgender adolescents (M age, 15.99 years) seen at specialty clinics in Toronto, Canada, Amsterdam, the Netherlands, and London, UK (total N = 2771). Suicidality was measured using two items from the Child Behavior Checklist (CBCL) and the Youth Self-Report (YSR). The CBCL/YSR referred and non-referred standardization samples from both the U.S. and the Netherlands were used for comparative purposes. Multiple linear regression analyses showed that there was significant between-clinic variation in suicidality on both the CBCL and the YSR; in addition, suicidality was consistently higher among birth-assigned females and strongly associated with degree of general behavioral and emotional problems. Compared to the U.S. and Dutch CBCL/YSR standardization samples, the relative risk of suicidality was somewhat higher than referred adolescents but substantially higher than non-referred adolescents. The results were discussed in relation to both gender identity specific and more general risk factors for suicidality.

Gender Dysphoria in the Pediatric Population: Initial Experience of a Transdisciplinary Group

Introduction Although there is an increasing experience in the management of transgender individuals, this has not been thoroughly explored in children. The need to establish a comprehensive and transdisciplinary management is of critical importance. In order to solve this issue, we want to report the results of a cohort of individuals with gender dysphoria (GD) seen by our transdisciplinary group from a social and clinical and health access perspective.

Methods A 10-year retrospective case series of all patients that had been seen by our transdisciplinary team was reviewed. The main demographic characteristics were described, as well as impact variables in terms of diagnosis and treatment of these individuals. A social description of each individual was described. Frequency, distribution, and central tendency measures were evaluated for data presentation. IBM SPSS Statistics for Windows, version 24.0 (IBM Corp, Armonk, NY) software was used.

Results Four cases of GD were included. Three had male to female dysphoria and one female to male. The median reported age of GD awareness was 6 years old (between 4 and 8 years old), and the median time between GD awareness and the 1st medical evaluation was 7 years for all individuals. The median age at gender role expression was 12 years old (between 10 and 14 years old). All patients had already assumed their experienced gender role before the 1st evaluation by our group. The median age at the 1st evaluation by our group was 13 years old (between 10 and 16 years old); three of the patients were evaluated after initiation of puberty. In the present study, individuals with GD demonstrated having health care access barriers for their transition process. Referral times are high, and individuals with GD are cared after pubertal development, which is related to suboptimal outcomes. The spectrum of GD is broad, and management must be individualized according to expectations.

Conclusion Individuals with GD face multiple access barriers that limit their possibility of being seen by a transdisciplinary team. This reflects in longer waiting times that negatively impact medical management. Gender dysphoria is a wide spectrum, and individuals should be evaluated individually by a transdisciplinary team.

Reflections on the Clinician's Role with Individuals Who Self-identify as Transgender

The fact that modern patterns of the treatment of trans individuals are not based on controlled or long-term comprehensive follow-up studies has allowed many ethical tensions to persist. These have been intensifying as the numbers of adolescent girls declare themselves to be trans, have gender dysphoria, or are "boys." This essay aims to assist clinicians in their initial approach to trans patients of any age. Gender identity is only one aspect of an individual's multifaceted identity. The contributions to the passionate positions in the trans culture debate are discussed along with the controversy over the official, not falsifiable, position that all gender identities are inherently normal. The essay posits that it is relevant and ethical to investigate the forces that may have propelled an individual to create and announce a new identity. Some of these biological, social, and psychological forces are enumerated. Using the adolescent patient as an example, a model for a comprehensive evaluation process and its goals are provided. The essay is framed within a developmental perspective.

Psychiatric morbidity among adult transgender people in Iran

Psychiatric morbidity among transgender and gender diverse people is thought to be to an important extent related to socio-cultural intolerance, but such morbidity has been understudied in non-western socio-political contexts. This study aims to report the psychiatric profiles of clients who are seeking gender-affirming treatment in a gender clinic in Iran. All transgender people who were consecutively referred to the Mashhad University of Medical Sciences in Mashhad, Iran, between February 2015 and December 2016 were investigated. Clients were evaluated during at least four sessions when sociodemographic and psychiatric characteristics were collected. Out of 209 clients, 205 were included (transmen (TM), N = 110; transwomen (TW) N = 95). A subset of these were assessed using Structured Clinical Interview based for DSM-5 (n = 154). The mean age of participants was 24.41 (SD = 6.316; range, 15-43). There was no significant difference between transmen and transwomen (p = 0.960); 48% (80 out of 154) of participants were found to have at least one current psychiatric condition currently, and 67% (138 out of 205) during their lifetime. Depressive and trauma- and stressor-related disorders were the most common conditions. Prevalence rates were similar in both genders. In both TM and TW groups, as many as 70% of the clients reported that they had experienced suicidal ideation. These findings are surprisingly similar to those of western studies despite the more extreme difficulties Iranian transgender people face in their lives in a non-western socio-political context.

An anthropometric study of sexual orientation and gender identity in Thailand

The biodevelopment of psychological sex differentiation is putatively reflected in several anthropometrics. We examined eight anthropometrics in 1404 Thai participants varying in sex, sexual orientation, and gender identity/expression: heterosexual men and women, gay men, lesbian women, bisexual women, sao praphet song (transgender birth-assigned males), toms (transgender birth-assigned females), and dees (birth-assigned females attracted to toms). Exploratory factor analyses indicated the biomarkers should be analyzed independently. Using regressions, in birth-assigned males, less male-typical second-to-fourth digit ratios in the left hand were associated with sexual orientation towards men regardless of gender identity/expression, whereas shorter height and long-bone growth in the arms and legs were more evident among sao praphet song-who are both sexually oriented towards men and markedly feminine. In birth-assigned females, there were no clear sexual orientation effects, but there were possible gender-related effects. Groups of individuals who tend to be more masculine (i.e., toms, lesbians) showed more male-typical patterns on weight and leg length than some groups of individuals who tend to be less masculine (i.e., heterosexual women, dees). Thus, it appears the various anthropometrics inform separate biodevelopmental processes that differentially relate to sexual orientation and gender identity/expression depending on the measure in question as well as birth-assigned sex.

Primary headaches among gender dysphoric female-to-male individuals: A cross-sectional survey on gender transition experience

OBJECTIVE

To investigate the frequency, attack characteristics, and treatment experiences of migraine and tension-type headache (TTH) among gender dysphoric female-to-male (FtM) participants as well as in relation to psychiatric comorbidities and real-life experience that relates to being transgender in Turkey.

BACKGROUND

There are only a few publications to date on transgender individuals with headache. Further studies to understand the distinctive needs might provide better management.

METHODS

A total of 88 gender dysphoric FtM individuals (mean (SD) age: 24.8 (5.7) years) were included on a voluntary basis in this cross-sectional survey. Each participant filled out the questionnaire form that elicited items on sociodemographic characteristics, Gender Identity Transition Inventory, Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), and Headache Questionnaire.

RESULTS

Overall, 32/88 (36.4%; 95% confidence interval [CI]: 27.0%-47.0%) participants were diagnosed with migraine, and 36/88 (40.9%; 95% CI: 31.5%-52.3%) participants were diagnosed with TTH. High rates of unemployment, smoking, and social drinking were observed in our sample compared with the general population in Turkey. The three-item ID migraine screener was positive in 20.5% (18/88 patients) of our population. Patients with migraine in comparison with patients with TTH had statistically significantly higher BDI [12.0 (1-50) vs. 7.0 (0-33); p = 0.013] and BAI [13 (1-48) vs. 5 (0-22); p = 0.016] scores, longer headaches in the past month [median 3 vs. 1 day; p < 0.001], higher Numerical Rating Scale scores for headache severity [7 (2-10) vs. 5 (1-9), p < 0.001], and higher likelihood of menstruation acting as a triggering factor [8/32 patients (25.0%) vs. 0/36 patients (0.0%); p = 0.001] as well as increased rates of previously given diagnosis by a physician [15/32 patients (46.9%) vs. 4/36 patients (11.1%); p < 0.001], a greater number of neuroimaging tests being performed [12/32 patients (37.5%) vs. 3/36 patients (9.1%); p = 0.012], and a higher rate of emergency room utilization [7/32 patients (21.9%) vs. 1/36 patients (2.8%); p = 0.039] for headache.

CONCLUSIONS

In the FtM transgender population we investigated, migraine and TTH were quite common. The screening and early recognition of comorbid migraine, as well as the comorbid depression and anxiety, seem to be important in gender dysphoric FtM individuals. Further studies are needed to better understand the potential interaction of migraine with comorbid psychiatric disorders and the prevalence of headache types and gender-affirmative hormone treatment outcomes in the transgender population.

Cortical Gyrification in Transgender Individuals

Gender incongruence (GI) is characterized by a feeling of estrangement from the own body in the context of self. GI is often described in people who identify as transgender. The underlying mechanisms are unknown. Data from MRI measurements and tests of own body perception triggered us to pose a model that GI in transgender persons (TGI) could be associated with a disconnection within the brain circuits mediating the perception of own body as self. This is a departure from a previous model of sex atypical cerebral dimorphism, introducing a concept that better accords with a core feature of TGI. The present MRI study of 54 hormone naive transmen (TrM), 38 transwomen (TrW), 44 cismen and 41 ciswomen show that cortical gyrification, a metric that reflects early maturation of cerebral cortex, is significantly lower in transgender compared with cisgender participants. This reduction is limited to the occipito-parietal cortex and the sensory motor cortex, regions encoding own body image and body ownership. Moreover, the cortical gyrification correlated inversely with own body-self incongruence in these regions. These novel data suggest that GI in TGI may originate in the neurodevelopment of body image encoding regions. The results add potentially to understanding neurobiological contributors to gender identity.

Gender Dysphoria in Psychiatric Practice: Understanding the Clinical Ambiguity and Management

There have been several myths and misconceptions about the dichotomous understanding of sex and gender. While sex is biologically determined, gender and gender identity depend on childhood experiences, upbringing, social expectations, beliefs, family environment, and peer interactions and is socially constructed. Gender dysphoria (GD) is the extreme distress experienced by an individual because of a mismatch between their gender identity and the sex assigned at birth. GD has been an ambiguous category in psychiatry, initially termed as “gender identity disorder” till Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition ( DSM-5) considered removal of the term “disorder” to reduce the stigma associated. The critical element in GD is “clinically significant distress” that differentiates it from gender nonconformity. Individuals with GD identify themselves as transgender and frequently are victims of coercive social norms, discrimination, and stigma. This leads to delay in expression of distress, psychiatric mismanagement, and high comorbidity of depression, anxiety, post-traumatic stress, self-harm, and suicidality. Though management involves a holistic multidisciplinary approach including psychotherapy, social support, and gender-reassignment treatments (medical/surgical), there has been considerable debate and ambiguity related to the same. With this background, the article critics the understanding of GD, focuses on the WPATH SOC-7 treatment guidelines, and highlights the role of mental health professionals for better care.

Issues in Working with Transgender Individuals Who Sexually Harm

PURPOSE OF REVIEW

I review the recent literature related to the assessment, treatment, and management of transgender individuals who sexually harm.

RECENT FINDINGS

There are no empirical research studies directly focused on the care of this group of individuals that have only recently been identified as an important sub-population among people who sexually harm. Related empirical research and other important professional literature do exist to inform clinicians regarding treatment guidelines for transgender mental healthcare. Research is needed to determine how best to assess sexual violence recidivism risk and to distinguish unique treatment needs for transgender individuals who sexually harm. Strength-based approaches to the treatment of sexual violence can help organize treatment approaches to assist transgender individuals in avoiding future incidents of sexually harmful behavior.

Gender incongruence and gender dysphoria in childhood and adolescence-current insights in diagnostics, management, and follow-up

Gender incongruence (GI) is defined as a condition in which the gender identity of a person does not align with the gender assigned at birth. Awareness and more social acceptance have paved the way for early medical intervention about two decades ago and are now part of good clinical practice although much robust data is lacking. Medical and mental treatment in adolescents with GI is complex and is recommended to take place within a team of mental health professionals, psychiatrists, endocrinologists, and other healthcare providers. The somatic treatment generally consists of the use of GnRH analogues to prevent the progression of biological puberty and subsequently gender-affirming hormonal treatment to develop sex characteristics of the self-identified gender and surgical procedures. However to optimize treatment regimens, long-term follow-up and additional studies are still needed. What is known • The prevalence of gender dysphoria increased significantly in the past years and can lead to significant complaints and burdens especially during puberty. • Pubertal suppression and gender-affirmed treatment can be effectively used in adolescence with gender dysphoria. What is new • Transgender mental and medical healthcare is a long-lasting process during which not only the child/adolescent with GI but also their parents/family have to be counseled in making choices about their social, medical, and legal transitions. • There are an increasing number of transgender persons defining as nonbinary. Therefore, an individualized approach by an experienced team is necessary.

2D:4D Digit Ratios in Adults with Gender Dysphoria: A Comparison to Their Unaffected Same-Sex Heterosexual Siblings, Cisgender Heterosexual Men, and Cisgender Heterosexual Women

We compared gender dysphoria (GD) patients and their same-sex siblings in terms of their 2D:4D ratios, which may reflect prenatal exposure to androgen, one of the possible etiological mechanisms underlying GD. Sixty-eight GD patients (46 Female-to-Male [FtM]; 22 Male-to-Female [MtF]), 68 siblings (46 sisters of FtMs; 22 brothers of MtFs), and 118 heterosexual controls (62 female; 56 male) were included in the study. FtMs were gynephilic and MtFs were androphilic. We found that 2D:4D ratios in the both right hand (p < .001) and the left hand (p = .003) were lower in male controls than in female controls. Regarding right hands, FtM GD patients had lower 2D:4D ratios than female controls (p < .001) but their ratios did not differ from those of their sisters or male controls. FtM GD patients had no significant difference in their left-hand 2D:4D ratios compared to their sisters or female and male controls. While there was no significant difference in right hands between FtM's sisters and male controls, left-hand 2D:4D ratios were significantly higher in FtM's sisters (p = .017). MtF GD patients had lower right-hand 2D:4D ratios than female controls (p <.001), but their right-hand ratios did not differ from those of their brothers and male controls. There was no significant difference in left-hand 2D:4D ratios between MtF GD patients, and their brothers, or female and male controls. FtM GD patients showed significantly masculinized right-hand 2D:4D ratios, while there was no evidence of feminization in MtF GD patients.

"There Is Nothing to Do About It": Nonbinary Individuals' Experience of Gender Dysphoria

Purpose: Clinical definitions of gender dysphoria have primarily centered on a binary conceptualization of gender. This study aimed to understand nonbinary transindividuals' experiences of gender dysphoria. Methods: Data were collected online from a nonclinical sample comprised of 205 nonbinary and agender participants. Analysis focused on answers to a single open-ended question prompting participants to describe their gender dysphoria as it relates to their body and/or appearance. Results: First, content analysis was used to document 11 contextual elements in which participants described their dysphoria with regard to three overarching categories, including no gender dysphoria (no issues with body, no dysphoria), aspects of gender/sex (naming gender identity, naming assigned sex, gender role, or expression), and aspects of body (body shape, genitals, chest, secondary sex characteristics, hormones, reproductive capability). Second, thematic analysis revealed six central themes describing the unique way gender dysphoria is experienced by nonbinary individuals: (1) Androgyny or Fluidity, (2) Feminine and Masculine Traits, (3) Dysphoria vs. Expression or Appearance, (4) Varying or Shifting Dysphoria, (5) No Solution, and (6) Trade-off/Loss. Conclusion: Results of this study suggest that nonbinary transindividuals experience gender dysphoria in unique ways. These findings highlight the need to develop clinical assessments of gender dysphoria that reflect nonbinary experience, and to outline explicit medical protocols for interventions tailored to achieve a desired outcome of physical androgyny.

Testosterone therapy masculinizes speech and gender presentation in transgender men

Voice is one of the most noticeably dimorphic traits in humans and plays a central role in gender presentation. Transgender males seeking to align internal identity and external gender expression frequently undergo testosterone (T) therapy to masculinize their voices and other traits. We aimed to determine the importance of changes in vocal masculinity for transgender men and to determine the effectiveness of T therapy at masculinizing three speech parameters: fundamental frequency (i.e., pitch) mean and variation (f_o and f_o-SD) and estimated vocal tract length (VTL) derived from formant frequencies. Thirty transgender men aged 20 to 40 rated their satisfaction with traits prior to and after T therapy and contributed speech samples and salivary T. Similar-aged cisgender men and women contributed speech samples for comparison. We show that transmen viewed voice change as critical to transition success compared to other masculine traits. However, T therapy may not be sufficient to fully masculinize speech: while f_o and f_o-SD were largely indistinguishable from cismen, VTL was intermediate between cismen and ciswomen. f_o was correlated with salivary T, and VTL associated with T therapy duration. This argues for additional approaches, such as behavior therapy and/or longer duration of hormone therapy, to improve speech transition.

The Assessment of Readiness and Consent for Hormone Therapy: A Semi-structured Interview for Use With Transgender and Gender Nonconforming Individuals

BACKGROUND

Evaluations to determine one's readiness to initiate hormone therapy are often requested by endocrinologists or institutions who provide gender-affirming hormone therapy for transgender adults. Unfortunately, many mental health providers report unfamiliarity in working with gender-nonconforming individuals and with the needs of this population, and do not feel equipped to conduct these evaluations.

OBJECTIVES

The purpose of this paper is to introduce an instrument that can guide providers to conduct a hormone readiness evaluation that is consistent with the current best practices model of care put forth by the World Professional Association for Transgender Health Standards of Care.

METHODS

Development of the Assessment of Readiness and Consent for Hormone Therapy (ARCH) was informed by published literature and consultation with subject matter experts. The tool has been revised through an iterative approach based on provider experience and client feedback.

RESULTS

The ARCH has been used as part of a national training initiative in transgender healthcare and favorable feedback has been received. Providers have reported that using the ARCH has increased their confidence in their ability to provide sensitive care that is consistent with best practice recommendations.

CONCLUSIONS

Use of the ARCH has the potential to enhance care for a population that often encounters poor access to culturally competent providers and treatments. The focused nature of the interview helps providers support and advocate for their clients by providing and gathering information necessary to make meaningful recommendations that will help hormone treatment candidates enhance their gender related quality of life.

Stigmatization, Resilience, and Mental Health Among a Diverse Community Sample of Transgender and Gender Nonbinary Individuals in the U.S

Transgender and gender nonbinary (TGNB) individuals were recently designated a health disparity population by the U.S. National Institutes of Health. We examined the effect of gender-related discrimination and resilience factors on the mental health of a community sample diverse in gender identity, age, and race/ethnicity. We report on the baseline data of a longitudinal study of transgender identity development across the lifespan with 330 TGNB individuals recruited through venue-based recruitment in three major metropolitan areas in the U.S. Mean age of participants was 34.4 years (SD = 13.7). Structured interviews collected self-report data on sociodemographics, gender-related discrimination, mental health, and resilience. We used hierarchical regression to examine the association between gender-related discrimination and psychological distress (BSI-18) and tested the moderating effect of family support, transgender community connectedness, gender literacy, and transgender activism on this relationship. In adjusted analyses, gender-related discrimination was positively associated with psychological distress. Family support was negatively associated with psychological distress. Contrary to our expectations, gender literacy and transgender activism were positively associated with psychological distress, while no significant relationship was found for transgender community connectedness. Family support, transgender community connectedness, gender literacy, and transgender activism did not moderate the effect of gender-related discrimination on psychological distress. Future mental health interventions should consider leveraging family support among TGNB individuals. Longitudinal studies are needed to better understand the role of gender literacy and activism with respect to mental health and development of identity and resilience among TGNB people.

Subjective Ratings of Gender Dysphoria Scales by Transgender Individuals

The present research explored transgender individuals' subjective ratings of two clinical measures of gender dysphoria: the Gender Identity/Gender Dysphoria Questionnaire for Adolescents and Adults (GIDYQ-AA) and the Utrecht Gender Dysphoria Scale (UGDS). Participants read each scale and provided a global rating regarding how well they captured their experiences of gender dysphoria. Participants included 622 transgender individuals who identified as transfeminine (n = 221), transmasculine (n = 206), and non-binary/agender (n = 195). Findings indicated clear patterns of responses across gender identity and assigned sex, but not clinical diagnosis. For the GIDYQ-AA, transfeminine and transmasculine individuals rated the scales more positively than did non-binary/agender individuals. In addition, participants who were assigned male rated the scale to be a more accurate measure of their dysphoria than did participants who were assigned female. For the UGDS, transfeminine individuals rated the scale most positively, followed by transmasculine individuals, and then non-binary/agender individuals. All pairwise comparisons were significant. Likewise, participants who were assigned male rated the scale to be a more accurate measure than did those who were assigned female. It is important to note that subjective ratings were relatively low (M = 3.40, SD = 1.09 for GIDYQ-AA; M = 3.43, SD = 1.22 for UGDS on a 5-point scale) where little more than half of the participants (52.5% GIDYQ-AA; 54% UGDS) agreed or strongly agreed that the scales captured their experience. Discussion focused on the implications for using these measures of gender dysphoria in both clinical and research settings.

Predictive Pattern Classification Can Distinguish Gender Identity Subtypes from Behavior and Brain Imaging

The exact neurobiological underpinnings of gender identity (i.e., the subjective perception of oneself belonging to a certain gender) still remain unknown. Combining both resting-state functional connectivity and behavioral data, we examined gender identity in cisgender and transgender persons using a data-driven machine learning strategy. Intrinsic functional connectivity and questionnaire data were obtained from cisgender (men/women) and transgender (trans men/trans women) individuals. Machine learning algorithms reliably detected gender identity with high prediction accuracy in each of the four groups based on connectivity signatures alone. The four normative gender groups were classified with accuracies ranging from 48% to 62% (exceeding chance level at 25%). These connectivity-based classification accuracies exceeded those obtained from a widely established behavioral instrument for gender identity. Using canonical correlation analyses, functional brain measurements and questionnaire data were then integrated to delineate nine canonical vectors (i.e., brain-gender axes), providing a multilevel window into the conventional sex dichotomy. Our dimensional gender perspective captures four distinguishable brain phenotypes for gender identity, advocating a biologically grounded reconceptualization of gender dimorphism. We hope to pave the way towards objective, data-driven diagnostic markers for gender identity and transgender, taking into account neurobiological and behavioral differences in an integrative modeling approach.

Mental health is biological health: Why tackling "diseases of the mind" is an imperative for biological anthropology in the 21st century

The germ theory of disease and the attendant public health initiatives, including sanitation, vaccination, and antibiotic treatment, led to dramatic increases in global life expectancy. As the prevalence of infectious disease declines, mental disorders are emerging as major contributors to the global burden of disease. Scientists understand little about the etiology of mental disorders, however, and many of the most popular psychopharmacological treatments, such as antidepressants and antipsychotics, have only moderate-to-weak efficacy in treating symptoms and fail to target biological systems that correspond to discrete psychiatric syndromes. Consequently, despite dramatic increases in the treatment of some mental disorders, there has been no decrease in the prevalence of most mental disorders since accurate record keeping began. Many researchers and theorists are therefore endeavoring to rethink psychiatry from the ground-up. Anthropology, especially biological anthropology, can offer critical theoretical and empirical insights to combat mental illness globally. Biological anthropologists are unique in that we take a panhuman approach to human health and behavior and are trained to address each of Tinbergen's four levels of analysis as well as culture. The field is thus exceptionally well-situated to help resolve the mysteries of mental illness by integrating biological, evolutionary, and sociocultural perspectives.

Cadaver Study of Combined Neurovascular Sensate Flaps to Create Vaginal Erogenous Sensation During Male-to-Female Genital Confirmation Surgery: The Pedicle "O" Flap

PURPOSE

The lack of erogenous sensitivity in the neovagina is one of the major shortcomings for patients undergoing male-to-female genital confirmation surgery. Remnant fibers of the dorsal nerve of the penis (DNP) after clitroplasty can potentially be used for a second neurovascular pedicle flap for intravaginal erogenous sensation.

METHODS

An anatomic dissection of the DNP was performed in 10 male frozen pelvises to identify major trunks and their branches. Lateral branches of DNP were preserved for a sensate "O" pedicle flap for the vagina. The number of main branches in the lateral dorsal aspect of the penis was calculated to ensure sufficient erogenous innervation to the vagina. Cross sections of the penis were used for histological analysis. Optimal width and length of the new sensate flap were described.

RESULTS

There were 1, 2, and 3 main branches in the lateral compartment in 2 (20%), 6 (30.7%), and 2 (42.8%) cadavers, respectively. A sensate pedicle flap from the lateral aspect of the glans penis with a mean width of 1.14 cm (range, 0.9-1.28 cm) ensured at least one main branch of the DNP for erogenous sensitivity of the vagina. This sensate vaginal flap and its neurovascular pedicle had a mean length of 9.8 cm (range, 8.7-10.3 cm) allowing its inset into the anterior vaginal canal.

CONCLUSION

Lateral branches of the DNP can be preserved for a pedicle sensate flap to the vagina, which can provide patients with an erogenous vaginal "spot" during male-to-female confirmation surgery.

"Diagnosing" Gender? Categorizing Gender-Identity Variants in the Anthropocene

In recent decades, two interrelated major controversies have been unfolding in the area of sex/gender research. (1) Are gender-identity variants to be understood as psychopathology or natural variation? (2) Is gender (and perhaps even sex) better conceptualized as binary or non-binary? The answer depends on the conceptual context and related considerations of utility. In the context of evolutionary biology, marked variants of sex and gender decrease reproductive success and are, thereby, deemed pathologic. In the present era of the anthropocene, however, the material conditions underlying the traditional division of labor between the sexes and the role of reproductive success have dramatically changed. These changes decrease the psychosocial importance of the binary gender distinction, provide more freedom for non-binary gender expression and identity formation, and render the distinction of pathologic and non-pathologic less useful, unless gender dysphoria develops secondary to a psychiatric condition. Although most people state their gender identity in the form of a nominal category, most self-report or interview-based ratings and multi-item scales of gender expression and/or identity show continuous distributions, either unimodal-asymmetric or bimodal, depending on whether they are designed for one or both of the traditional genders. Similarly, the rating scales of androgen-influenced variants of the genitalia-usually designed for one of the traditional sexes-typically represent a unipolar-asymmetric continuum. However, the binary gender system remains the primary framework against which individuals evaluate themselves. For those who develop gender dysphoria, assistance by mental-health service providers continues to be important.

Gender, mental health and ageing

This article presents a broad narrative review of the epidemiological evidence on how and why the mental health of older adults varies by gender. We draw upon international research literatures spanning gerontology and population mental health, as well as major reports from global health agencies. Compared with older men, older women are more likely to experience common mental disorders such as depression and anxiety, although the gender gap is smaller than it is at younger ages. In contrast, the mortality-related impacts of poor mental health, including suicide, are more severe for older men. These gendered patterns vary by country and other social contexts. Factors proposed to account for these findings include cultural and social norms, differentiation of gender roles, disadvantage and (dis)empowerment across the life course, and the coping styles of older men. However, little research has explicitly tested these explanations. Research to date has overwhelmingly focused on identifying differences in the mental health of older men and women. Notably, most studies have been restricted to binary comparisons, lacking the data to disentangle sex and gender dynamics, and few studies have examined the mental health of minority gendered adults in later life. Finally, there remains a need for high-quality population-based research into the mental health of those aged over 80 that includes coverage of people living in residential aged care settings.

Metoidioplasty and groin flap phalloplasty as two surgical methods for the creation of a neophallus in female-to-male gender-confirming surgery: A retrospective study comprising 123 operated patients

Background

In gender-confirming surgery of the female-to-male gender dysphoric patient, there is currently no ideal method for the creation of a neophallus. Historically, in our clinic, groin flap phalloplasty (GFP) has been the dominating method, but during the last 20 years, it has gradually been replaced with metoidioplasty (MP). The aim of this study was to investigate whether this change of method has influenced factors such as the frequency of complications and the number of operations needed to complete the reconstruction of the neophallus.

Methods

This is a retrospective, single-centre, study comprising 123 consecutive female-to-male patients receiving a neophallus by GFP or MP between 2002 and 2015 at Linköping University Hospital, Sweden.

Results

One-hundred twenty-three patients underwent 126 primary surgical procedures (39 GFPs and 87 MPs) with the intention of reconstructing a neophallus. The mean number of procedures required in the GFP group was 5.2 ± 2.7 compared with that of 2.4 ± 1.7 in the MP group (p < 0.001). In the GFP group, 18/39 (46.2%) had a documented complication compared with 30/87 (34.5%) in the MP group; however, the difference was not statistically significant (p = 0.21).

Conclusions

The present study shows that the shift in method from GFP to MP has resulted in a decreased number of complications as well as a decrease in total surgical occasions. Both methods were found to be associated with relatively high frequencies of complications, however, mostly minor.

Self-harm prevalence and ideation in a community sample of cis, trans and other youth

Background: Trans youth have been reported to have high rates of self-harm, depression and bullying, and find it difficult to seek support. However, much of this research comes from gender identity clinics; non-clinical samples and those who reject gender binaries remain under-researched. Aims: This study investigated the experiences of a community school-based sample of Trans, identifying youth, Other, and cis-gendered adolescents in relation to their experiences of low mood, bullying, associated support, self-harm ideation and peer-related self-harm. Methods: An online survey was completed by 8440 13-17 year olds (3625 male, 4361 female, 227 Other, and 55 Trans). Results: Trans and Other students had significantly higher rates of self-harm ideation and peer self-harm, in comparison to cis-gendered students. These Trans and Other students reported significantly higher rates of bullying and self-reported depression and significantly less support from teachers and staff at school, in fact these students did not know where to go to access help. Discussion: This community sample confirms findings of high rates of self-harm ideation, self-reported depression and bullying for Trans youth as previously reported in clinic-based samples. However, by accessing a community sample, the salience of the category "Other" was established for young people today. While Other and Trans identified students both struggled to find support, those who identified as Trans were more likely to have been bullied, and have experienced self-reported depression and thoughts of self-harm. Thus, those who identify as transgender represent a high-risk group that needs targeted support within schools and by statutory and nonstatutory community services. Unpacking the category of Other would be beneficial for future research, as well as exploring resilience within this group and intersecting identities such as sexuality, Autism, or experiences such as earlier abuse.

Psychosexual Aspects, Effects of Prenatal Androgen Exposure, and Gender Change in 46,XY Disorders of Sex Development

CONTEXT

In 46,XY disorders of sexual development (DSD) patients, several factors may affect psychosexual development, leading to gender identity discrepancy and gender change later in life. Prenatal sexual steroid exposure and external genital virilization are considered to influence human psychosexual development, but their roles not completely understood yet.

DESIGN

A total of 144 individuals (18 to 60 years of age) with a clinical/molecular diagnosis of 46,XY DSD from a single tertiary center were enrolled. Psychosexual outcomes (gender role, gender identity, and sexual orientation) were assessed using questionnaires and psychological test. The Sinnecker score was used for genital virilization measurement. Prenatal androgen exposure was estimated according to 46,XY DSD etiology.

RESULTS

We found a positive association between prenatal androgen exposure and male psychosexual outcomes. Alternatively, prenatal estrogen exposure, age of gonadectomy, and the degree of external genital virilization did not influence any psychosexual outcome. There were 19% (n = 27) with gender change, which was associated with prenatal androgen exposure (P < 0.001) but not with the external genital virilization. The median age of gender change was 15 years, but most of the patients reported the desire for gender change earlier.

CONCLUSIONS

Prenatal androgen exposure influenced psychosexual development in 46,XY DSD favoring male psychosexuality in all psychosexual outcomes, whereas the degree of external genital virilization did not influence these outcomes. The organizational effect of sexual steroids on psychosexuality at puberty appears to be weak in comparison with the prenatal effects. Prenatal androgen exposure also influenced female-to-male gender change frequency. All 46,XY DSD conditions with prenatal androgen exposure must be followed for gender issues in their management.

Self-Reported Gender Identity and Sexuality in an Online Sample of Cisgender, Transgender, and Gender-Diverse Individuals: An Exploratory Study

The relations between self-reported aspects of gender identity and sexuality were studied in an online sample of cisgender (n = 4,954), transgender (n = 406), and gender-diverse (n = 744) groups. Aspects of gender identity and sexual fantasies, attraction, behavior, and romantic relations were assessed using the Multi-gender Identity Questionnaire (Multi-GIQ) and a sexuality questionnaire. Results show a wide spectrum of gender experiences and sexual attractions within each group, an overlap among the groups, and very weak relations between atypical gender identity and atypical sexuality. At the group level, aspects of gender identity and sexuality were mainly predicted by gender and sex-gender configuration, with little contribution of sex assigned at birth. A principal component analysis (PCA) revealed that measures of gender identity and of sexuality were independent, the structure of sexuality was mostly related to gender, whereas the structure of gender identity was mostly related to sex-gender configuration. The results of both approaches suggest that measures of gender identity could roughly be divided into three classes: one including feeling as a man and feeling as a woman; a second including measures of nonbinary and "trans" feelings; and a third including feeling as a "real" woman and feeling as a "real" man. Our study adds to current scientific data that challenge dichotomous conventions within gender identity and sexuality research. Possible social and clinical implications are discussed.

Genetic Link Between Gender Dysphoria and Sex Hormone Signaling

CONTEXT

There is a likely genetic component to gender dysphoria, but association study data have been equivocal.

OBJECTIVE

We explored the specific hypothesis that gender dysphoria in transgender women is associated with variants in sex hormone-signaling genes responsible for undermasculinization and/or feminization.

DESIGN

Subject-control analysis included 380 transgender women and 344 control male subjects. Associations and interactions were investigated between functional variants in 12 sex hormone-signaling genes and gender dysphoria in transgender women.

SETTING

Patients were recruited from the Monash Gender Clinic, Monash Health, Melbourne, Australia, and the University of California, Los Angeles.

PATIENTS

Caucasian (non-Latino) transgender women were recruited who received a diagnosis of transsexualism [Diagnostic and Statistical Manual of Mental Disorders (DSM)-IV) or gender dysphoria (DSM-V)] pre- or postoperatively. Most were receiving hormone treatment at the time of recruitment.

MAIN OUTCOME MEASURED

Genomic DNA was genotyped for repeat length polymorphisms or single nucleotide polymorphisms.

RESULTS

A significant association was identified between gender dysphoria and ERα, SRD5A2, and STS alleles, as well as ERα and SULT2A1 genotypes. Several allele combinations were also overrepresented in transgender women, most involving AR (namely, AR-ERβ, AR-PGR, AR-COMT, CYP17-SRD5A2). Overrepresented alleles and genotypes are proposed to undermasculinize/feminize on the basis of their reported effects in other disease contexts.

CONCLUSION

Gender dysphoria may have an oligogenic component, with several genes involved in sex hormone-signaling contributing.
