Prevalence and demography of transsexualism in Belgium

Estimate and needs of the transgender adult population: the SPoT study

BACKGROUND

Despite the increasing interest in transgender health research, to date little is known about the size of the transgender and gender diverse (TGD) population.

METHODS

A web-based questionnaire survey was developed, including a collection of socio-demographic characteristics and disseminated online through social media. Gender incongruence was evaluated by using a 2-item approach assessing gender recorded at birth and gender identity. The primary objective of the present population-based study was to estimate the proportion of TGD people across ages among a large sample of people who answered a web-based survey. The secondary endpoints were to identify gender-affirming needs and possible barriers to healthcare access.

RESULTS

A total of 19,572 individuals participated in the survey, of whom 7.7% reported a gender identity different from the sex recorded at birth. A significantly higher proportion of TGD people was observed in the youngest group of participants compared with older ones. Among TGD people who participated in the study, 58.4% were nonbinary, and 49.1% experienced discrimination in accessing health care services. Nonbinary TGD participants reported both the need for legal name and gender change, along with hormonal and surgical interventions less frequently compared to binary persons.

CONCLUSIONS

Being TGD is not a marginal condition In Italy. A large proportion of TGD persons may not need medical and surgical treatments. TGD people often experience barriers to healthcare access relating to gender identity.

Referrals For Gender-Affirming Hormone Treatment in Croatia's National Network for Transgender Healthcare

A network of healthcare professionals specializing in transgender care was established in Croatia in 2011, and legal advancements were subsequently made in 2014. Both achievements made gender transition more transparent and thus more attainable in Croatia. This observational study was conducted to assess the number of transgender individuals initiating gender-affirming hormone treatment (GAHT) in Croatia and describes trends in age and sex assigned at birth. Between 2011 and 2022, a total of 111 transgender individuals initiated GAHT. Within the cohort, 52 were assigned male at birth (AMAB) and 59 were assigned female at birth (AFAB). The overall annual incidence rate of transgender individuals initiating GAHT was 0.52 per 100,000 age-adjusted individuals. There was a statistically significant increase (p < 0.01) in transgender individuals commencing GAHT before the COVID-19 pandemic. Furthermore, a rising trend toward masculinizing rather than feminizing treatment was identified (p < 0.05), particularly among younger transgender individuals. The COVID-19 pandemic disrupted these trends in 2020, except for the trend of initiating therapy at a younger age (p < 0.01). The annual incidence and age distribution trends of transgender individuals initiating GAHT in Croatia closely mirrored those in other European countries, with a higher prevalence of individuals assigned female at birth. The study underscores a significant rise in the number of individuals initiating gender-affirming hormone treatment, emphasizing the need for proper legal regulation and healthcare system response.

Fertility preservation and realignment in transgender women

Medical care for transgender people is multi-faceted and attention to individual reproductive aspirations and planning are an essential, yet often overlooked aspect of care. Given the impact of hormonal therapy and other gender affirmation procedures on reproductive function, extensive counselling and consideration of fertility preservation is recommended prior to their commencement. This review article explores the reproductive aspirations of transgender women and considers the current disparity between stated desires regarding utilisation of fertility preservation services. Current fertility preservation options and prospective treatments currently showing promise in the research arena are explored.

Tissue Engineering Neovagina for Vaginoplasty in Mayer-Rokitansky-Küster-Hauser Syndrome and Gender Dysphoria Patients: A Systematic Review

Background: Vaginoplasty is a surgical solution to multiple disorders, including Mayer-Rokitansky-Küster-Hauser syndrome and male-to-female gender dysphoria. Using nonvaginal tissues for these reconstructions is associated with many complications, and autologous vaginal tissue may not be sufficient. The potential of tissue engineering for vaginoplasty was studied through a systematic bibliography search. Cell types, biomaterials, and signaling factors were analyzed by investigating advantages, disadvantages, complications, and research quantity. Search Methods: A systematic search was performed in Medline, EMBASE, Web of Science, and Scopus until March 8, 2022. Term combinations for tissue engineering, guided tissue regeneration, regenerative medicine, and tissue scaffold were applied, together with vaginoplasty and neovagina. The snowball method was performed on references and a Google Scholar search on the first 200 hits. Original research articles on human and/or animal subjects that met the inclusion (reconstruction of vaginal tissue and tissue engineering method) and no exclusion criteria (not available as full text; written in foreign language; nonoriginal study article; genital surgery other than neovaginal reconstruction; and vaginal reconstruction with autologous or allogenic tissue without tissue engineering or scaffold) were assessed. The Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) checklist, the Newcastle-Ottawa Scale, and the Gold Standard Publication Checklist were used to evaluate article quality and bias. Outcomes: A total of 31 out of 1569 articles were included. Data extraction was based on cell origin and type, biomaterial nature and composition, host species, number of hosts and controls, neovaginal size, replacement fraction, and signaling factors. An overview of used tissue engineering methods for neovaginal formation was created, showing high variance of cell types, biomaterials, and signaling factors and the same topics were rarely covered multiple times. Autologous vaginal cells and extracellular matrix-based biomaterials showed preferential properties, and stem cells carry potential. However, quality confirmation of orthotopic cell-seeded acellular vaginal matrix by clinical trials is needed as well as exploration of signaling factors for vaginoplasty. Impact statement General article quality was weak to sufficient due to unreported cofounders and incomplete animal study descriptions. Article quality and heterogenicity made identification of optimal cell types, biomaterials, or signaling factors unreliable. However, trends showed that autologous cells prevent complications and compatibility issues such as healthy cell destruction, whereas stem cells prevent cross talk (interference of signaling pathways by signals from other cell types) and rejection (but need confirmation testing beyond animal trials). Natural (orthotopic) extracellular matrix biomaterials have great preferential properties that encourage future research, and signaling factors for vascularization are important for tissue engineering of full-sized neovagina.

Prostate-Specific Antigen Screening in Transgender Patients

CONTEXT

Approximately 0.4-1.3% of the worldwide population is transgender. Although the exact prevalence is unknown, there is an increase in open identification as transgender. Among transgender women (TW), the prostate is retained even after gender-affirmation surgery, thus necessitating ongoing screening for prostate cancer (CaP). However, little is known about CaP screening in this population.

OBJECTIVE

To assess our current understanding of CaP incidence and prostate-specific antigen (PSA) screening in TW.

EVIDENCE ACQUISITION

We performed a nonsystematic narrative review of all PubMed publications through June 2022 according to the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) statement. Given the limited primary research on this subject, case reports were also included. Studies were reviewed to understand PSA screening practices and reports of CaP in this population, as applicable.

EVIDENCE SYNTHESIS

There is no consensus regarding PSA screening in TW from any of the major societies, and TW are largely absent from guidelines. Case report data suggest that TW with CaP may have more aggressive disease, and these cancers may have been pre-existing prior to present before gender-affirming hormone therapy (GAHT) or be castrate-resistant.

CONCLUSIONS

We are in the infancy of our understanding of PSA screening in TW. Important avenues for future research include understanding the risks/benefits of PSA screening in TW, how best to mitigate potential negative psychological effects of PSA screening in TW, establishing baseline PSA values for those on GAHT (and determining what values should be considered "elevated"), establishing when to initiate PSA screening for those on GAHT, and establishing the accuracy of biomarkers for those undergoing GAHT.

PATIENT SUMMARY

We examined patterns of prostate cancer screening for transgender women. Little is known about prostate cancer incidence or screening in this population. Additional research is needed to establish guidelines for screening in this population.

[Modalities of gynecological follow-up of transgender patients - Literature review]

Transgender patients are at increased risk of cancer, sexually transmitted diseases, short- and long-term postoperative complications in patients with vaginoplasty, but also unwanted pregnancy in non-hysterectomized trans men. However, access to care is often difficult for these patients, who often do not benefit from appropriate gynecological monitoring, especially for fear of judgment or discrimination. In view of the health risks of these patients, it is essential to be able to offer them specific and adapted gynecological follow-up. To date, there are no clear recommendations regarding the gynecological follow-up of transgender patients. We relied on the recommendations of the World Professional Association of Transgender Health (W-PATH) and the Endocrine Society Guideline and performed a literature review. We carried out several searches via pubmed in order to explore one by one the different aspects of gynecological follow-up, in particular of non-hysterectomized transgender men and transgender women with a vaginoplasty. It emerges from this a lack of follow-up of transgender people, with a reluctance to consult a gynecologist, associated with the lack of knowledge and experience of health professionals. Due to the risks identical to those of the general population, added to those specific to transgender people, it is important to be able to offer these patients specialized and personalized gynecological follow-up, and to raise awareness and train health professionals on the importance of and the specificities of the gynecological follow-up of these patients.

Gender Affirmation in India—The Current State of Knowledge, Management, Legal and Legislative Situation

A mismatch between the birth sex of a person and psychological recognition of self (gender) leads to a gender expression, which is at variance with the societal norms, and thus gives rise to gender incongruence (GI). In the past few years, there has been a significant change in demographics, understanding of etiology, management, laws and legislations in the field of GI. The authors, who have been performing gender affirmative surgeries (GAS) since the past 27 years, present their experience in gender affirmation together with the current state of knowledge. Recent studies report a significant rise in prevalence of GI, which is similar to the experience of author and other large volume Gender identity clinics in India and worldwide. This article endeavors to provide the medical professional with the current state of knowledge in the field of GI, so that they are better equipped to optimally manage these patients.

"Transsexuality" and gender ratio in Poland: A case study on the East/West dichotomy

The article investigates scientific and journalistic discourses around differences in gender ratio among trans persons. The disparity between Poland and many other countries that was first noted in the 1980s was repeatedly associated with the different gender politics in the capitalist West and the (post) state-socialist East. Using Foucauldian methodology, the article claims that this discourse was constructed such that Poland's ratio-and consequently Poland's gender order-would always appear problematic, while Western countries were considered an invisible standard. Discourses around this ratio elucidate the role of heteronormativity and biological essentialism in the construction of the category of "transsexuality" in state-socialist Poland. The analysis also reveals that chronologies of LGBT and feminist movements had direct consequences for the theoretical and cultural spaces of trans identities.

The Epidemiology of Gender Dysphoria in Iran: The First Nationwide Study

Gender dysphoria (GD) is defined as a persistent and distressful incongruence between one's gender identity and one's at-birth-assigned sex. Sex reassignment has been religiously accepted for transgender individuals in postrevolutionary Iran since 1987; however, very little is known about how many individuals seek and receive such treatment annually. This study provides the first nationwide effort to assess the prevalence of GD in Iran as a function of diagnosis. The medical records of all transgender individuals referred to the Iranian Legal Medicine Organization between March 2012 and March 2017 were reviewed. All individuals diagnosed with GD were contacted. A total of 839 medical records meeting study criteria were received and evaluated. The prevalence of transgender individuals was estimated to be 1.46 per 100,000 Iranians with a transwoman (TW)/ transman (TM) ratio of 1:2. The mean age of individuals with GD at the time of referral was 25.22 (SD = 6.25) years for TW and 25.51 (SD = 5.66) years for TM. The findings are twofold. First, gender dysphoria is less prevalent in Iran than has been reported in Western countries. Second, the sex ratio is skewed toward at-birth-assigned females, which differs from what has been reported in Western countries. These findings have been interpreted in light of Iran's legal system, which is based on Islamic penal codes. These findings are of utmost importance for both health providers and legislators, as it can illustrate a more accurate picture of the transgender population in Iran.

Characterization of a transgender population in Portugal

INTRODUCTION

Gender dysphoria (GD) is a condition in which the individual's gender identity does not correspond to their biological sex, causing significant distress. Biological males who identify as females are referred to as transgender females or as showing male-to-female GD (MtF GD) and biological females who identify as males are referred to as transgender males or as showing female-to-male GD (FtM GD). In our center, there is a multidisciplinary consultation to approach and follow patients with GD.

AIM

We aimed to analyze the characteristics of the individuals who attend this consultation.

METHODS

Retrospective study of individuals attending the Sexual Medicine Group Consultation. Age, comorbidities, symptom onset, and hormonal and surgical treatment were analyzed.

RESULTS

114 patients were diagnosed with GD: 68.4% FtM GD and 31.6% MtF GD. Median age was 30.2±12 years. 63.2% reported symptom onset in childhood: 14.9% between 10 and 18 years, and 4.4% later than 18 years. Median age at treatment initiation was 23.1±7.1 years. Several individuals had concomitant medical conditions, notably smoking (n=37; 32.5%) and depression (n=26; 22.3%). The majority of (92.3% FtM GD and 88.9% MtF GD) were under hormone treatment, and about one-third had undergone some sex reassignment surgery.

DISCUSSION

We found higher prevalence of FtM than MtF, in contrast with most other studies. The reasons for this are not clear. A high percentage of our patients were self-medicated. Other characteristics were similar to those previously reported.

CONCLUSION

Medical requests by individuals with GD are increasing worldwide. To our knowledge, this is the first study to portray a case series in a consultation center dedicated to the diagnosis, treatment and follow-up of individuals with GD in Portugal.

Healthcare for Trans*gender People in Germany: Gaps, Challenges, and Perspectives

People whose gender does not correspond to the binary gender system, i.e., trans∗gender people, face two main problems when it comes to healthcare in Germany: (1) They often suffer from general psychiatric comorbidities as well as specific and significant mental distress due to gender dysphoria, and (2) the German healthcare system lacks sufficiently educated and clinically experienced medical personnel who are able to provide specialized healthcare. Aside from transition, it often is extremely difficult for trans∗gender people to get access to and be integrated into the medical system. Stigmatization and pathologization in treatment are widespread, as are long waiting times for specialized healthcare providers who are often only accessible to those trans∗gender people willing to travel long distances. Frequently, trans∗gender people face further difficulties and barriers after transition, as some healthcare professionals fail to provide suitable care (e.g., gynecological consultation for transmen). The ICD-11 German Modification (ICD-11-GM), which should be routinely used by 2022, implements a depathologization of trans∗gender people in the medical system. This paper compares the issues related to health and healthcare of trans∗gender people in Germany with those in other European countries. We review the care offered by specialized centers with regard to treatment of and support for trans∗gender people. We conclude with specific proposals that may contribute to establish an improved, up-to-date, gender-sensitive healthcare system.

Breast Implant-Associated Anaplastic Large Cell Lymphoma (BIA-ALCL): Review of Epidemiology and Prevalence Assessment in Europe

BACKGROUND

Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) epidemiologic studies focus on incidence and risk estimates.

OBJECTIVES

The aim of this study was to perform a thorough literature review, and to provide an accurate estimate of BIA-ALCL prevalence in Europe.

METHODS

We searched PubMed, Web of Science, SCOPUS, and Google Scholar databases to identify publications reporting BIA-ALCL epidemiology. Research was conducted between November 2019 and August 2020. European prevalence was assessed as the ratio between pathology-confirmed cases and breast implant-bearing individuals. The Committee on Device Safety and Development (CDSD) collected data from national plastic surgery societies, health authorities, and disease-specific registries to calculate the numerator. The denominator was estimated by combining European demographic data with scientific reports.

RESULTS

Our research identified 507 articles: 106 were excluded for not being relevant to BIA-ALCL. From the remaining 401 articles, we selected 35 that discussed epidemiology and 12 reviews. The CDSD reported 420 cases in Europe, with an overall prevalence of 1:13,745 cases in the 28 member states of the European Union (EU-28). Countries where specific measures have been implemented to tackle BIA-ALCL account for 61% of the EU-28 population and actively reported 382 cases with an overall prevalence of 1:9121.

CONCLUSION

Countries where specific measures have been implemented show a higher prevalence of BIA-ALCL compared with the European mean, suggesting that these countries have improved the detection of the condition and reduced underreporting, which affects the numerator value. Other nations should adopt projections based on these measures to avoid underestimating how widespread BIA-ALCL is.

The Repairing of the Recto-Neovaginal Fistula in a Male-to-Female Transgender Through Perineal Graciloplasty

Rectovaginal fistulas, which are abnormal epithelial-lined connections between the rectum and vagina, are challenging to treat. Treatment of recto-neovaginal fistulas is more complicated due to the altered perineal anatomy in individuals undergoing gender reassignment surgery. We present a recto-neovaginal fistula that occurred after reassignment surgery male-to-female transgender case of a was successfully treated with restorative perineal graciloplasty.

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.

Tracking trends of transgender health research online: are researchers and the public on the same page?

Altmetric Explorer was searched for the most popular online articles published in Pubmed-indexed journals. The 75 articles with the highest Altmetric Attention Score (AAS) were screened for article information (date, journal, access), authorship (number of authors, affiliation and origin of the corresponding author), and research (type, subject, funding). The reviewed articles displayed a mean AAS of 241.52, were broadcast 17.03 times by news agencies, posted on Twitter 101.47 times, downloaded by 67.21 Mendeley readers, and received 62.67 citations. There was intense online interest in the transgender health literature, mainly related to mental health and social well-being. Online visibility of transgender health articles was not significantly correlated with citation counts, implying that the public, likely including transgender persons and allies, may place emphasis on different health issues than scholars. Monitoring altmetrics and interactions on electronic media may help researchers conduct research that is more meaningful to transgender individuals, and to society in general.

Psychiatric disorders in female psychosexual disorders-a nationwide, cohort study in Taiwan : Psychiatric disorders and female psychosexual disorders

We aimed to investigate whether females with psychosexual disorders were associated with the risk of affective and other psychiatric disorders. A total of 2240 enrolled individuals, with 560 patients with psychosexual disorders and 1680 subjects without psychosexual disorders (1:3) matched for age and index year, from the Longitudinal Health Insurance Database, retrieved from the National Health Insurance Research Database (NHIRD), between 2000 and 2015 in Taiwan. The multivariate Cox regression model was used to compare the risk of developing psychiatric disorders during the 15 years of follow-up. There were 98 in the cohort with psychosexual disorders (736.07 per 100,000 person-year) and 119 in the non-cohort without psychosexual disorders (736.07 per 100,000 person-year) that developed psychiatric disorders. The multivariate Cox regression model revealed that the adjusted hazard ratio (HR) was 9.848 (95% CI = 7.298 - 13.291, p < 0.001), after the adjustment of age, monthly income, urbanization level, geographic region, and comorbidities. Female patients with psychosexual disorders were associated with the risk of psychiatric disorders. This finding could be a reminder for clinicians about the mental health problems in patients with psychosexual disorders.

Proportion of people identified as transgender and non-binary gender in Brazil

Studies estimate that gender-diverse persons represent 0.1 to 2% of populations investigated, but no such assessment was performed in Latin America. In a representative sample of Brazil's adult population (n = 6000), we investigated participants' sociodemographic characteristics and possible associations between these and current gender identity, categorized as cisgender, transgender or non-binary gender. We also investigated transgender individuals' distress associated with gender-related body characteristics. As main results, we found that transgender individuals represented 0.69% (CI95% = 0.48-0.90) of the sample, whereas non-binary persons were 1.19% (CI95% = 0.92-1.47). These percentages were not different among Brazil's 5 geographic regions. Preliminary analyses showed that transgender individuals were on average younger (32.8 ± 14.2 years, CI95% = 28.5-37.1), compared to cisgender (42.2 ± 15.9, CI95% = 42.5-42.8) and non-binary (42.1 ± 16.5 years, CI95% = 38.3-46.5) groups. Non-binary persons are less likely to be in a relationship compared to cisgender individuals (OR = 0.57, CI95% = 0.35-0.93). In the transgender group, 85% of transgender men and 50% of transgender women reported distress due to gender-related body characteristics. Our main findings draw attention that gender-diverse Brazilian individuals represent around 2% of the country's adult population (almost 3 million people), and are homogeneously located throughout the country, reiterating the urgency of public health policies for these individuals in the five Brazilian sub-regions.

[Fertility preservation for transwomen]

The evolution of medical care for transgender people currently makes it possible to propose fertility preservation. Fertility preservation should be initiated before the start of hormonal treatments and/or surgical procedures. The "reproductive" aspect and the desire for parenthood among transgender people have long been ignored. However, these aspects are important to consider and fertility preservation should be discussed before the start of the physical transition. The aim of this review is to assess the literature on fertility preservation for transgender women ("male to female"). Many uncertainties remain regarding the impact of hormonal treatments on the reproductive functions of transgender women and their reversibility. However, the significant increase in the number of recently published articles is evidence of the improvement in the conditions of access to these procedures for women starting a transition process. Nevertheless, there are still a number of barriers that can prevent or delay this process.

Effect of cross-sex hormones on the quality of life, depression and anxiety of transgender individuals: a quantitative systematic review

OBJECTIVE

The objective of the review was to evaluate the effectiveness of cross-sex hormone use in improving quality of life and the related measures of depression and anxiety in transgender individuals.

INTRODUCTION

Transgender medicine as a specialty is still in its infancy and is beginning to attract more primary care providers. The use of hormones to aid in gender transition is expected to provide benefit with regard to quality of life, but there have been few high-quality studies. Two previous systematic reviews were found. One review included studies where participants had gender-affirming surgery, and the other review considered only prospective studies. Both reviews found a benefit with the use of hormones, despite the lack of high-quality studies. To describe outcomes specifically associated with hormone therapy, this review focused on patients who had not yet had surgical interventions, with an aim to inform primary care providers who are considering providing gender transition related-care in their office or clinic.

INCLUSION CRITERIA

Eligible studies included participants who were transgender (trans) women, trans men or who did not identify with the gender binary and were using cross-sex hormones. This review only considered studies where hormone use was under medical supervision. Studies that included participants who already had any form of gender-affirming surgery were excluded, as were studies that did not use a validated tool to measure quality of life, depression or anxiety.

METHODS

A comprehensive database search of PubMed, CINAHL, Embase and PsycINFO was conducted in August and September of 2017. The search for unpublished studies and gray literature included Google, the New York Academy of Medicine and the World Professional Association for Transgender Health (WPATH) Conference Proceedings. No date limits were used in any part of the search. Study selection, critical appraisal and data extraction were conducted by two independent reviewers using the JBI protocols, standardized critical appraisal and data extraction tools.

RESULTS

Seven observational studies met the inclusion criteria for this review. The total number of transgender participants in all the included studies was 552. Population sizes in the studies ranged from 14 to 163. In general, the certainty of the findings was low to very low due to issues with imprecision and indirectness. The use of cross-sex hormones was associated with improved quality of life, depression and anxiety scores, although no causation can be inferred.

CONCLUSIONS

Transgender participants who were prescribed cross-sex hormones had statistically significant scores demonstrating improvement on the validated scales that measured quality of life, anxiety and depression when compared to transgender people who had enrolled in a sex-reassignment clinic but had not yet begun taking cross-sex hormones. However, because the certainty of this evidence was very low to low, recommendations for hormone use to improve quality of life, depression and anxiety could not be made. High-quality research on this issue is needed, as is the development of a quality-of-life tool specific to the transgender population.

Masculinizing genital gender-affirming surgery: metoidioplasty and urethral lengthening

Metoidioplasty denotes the creation of a neophallus out of the hormonally hypertrophied clitoris. Construction of an esthetically acceptable male-like genitalia while enabling micturition in standing position are the primary goals. Herein, we aim to review the literature regarding masculinizing gender-affirming genital surgery in the form of metoidioplasty, focusing on the steps related to urethral lengthening and reconstruction, and describe the authors' preferred surgical technique. Clitoral release, division of the urethral plate, native urethral lengthening with anterior vaginal wall flap, and neourethral tubularization using a combination of buccal mucosa graft and labia minora flap(s) seem to provide the best result in terms of urinary outcomes. This is reflected in a greater urethral length, higher probability of standing micturition, and lower incidence of fistula. Urethral complications, which can be encountered in up to 15% of the patients, may necessitate additional procedures. Some of the studies have reported successful penetrative intercourse following metoidioplasty. Case series about different metoidioplasty techniques do not allow head-to-head comparison due to non-standardized reporting and outcome assessment. Metoidioplasty can be offered to transgender men with sufficiently hypertrophied clitoris who wish to avoid a complicated, multistage, flap-based total phalloplasty, or for those individuals considering phalloplasty at a later date.

Genital Reconstructive Surgery in Male to Female Transgender Patients: A Systematic Review of Primary Surgical Techniques, Complication Profiles, and Functional Outcomes from 1950 to Present Day

CONTEXT

Genital reconstructive surgery (GRS) is a necessary part of transitioning for many transwomen, and there is evidence of positive effects on a person's well-being and sexual function. Surgical techniques have evolved, from pursuing aesthetic outcome to now functional outcome with natal females as the standard.

OBJECTIVE

To systematically review the evidence, identifying the surgical techniques used in primary GRS, their complications, functional outcomes, and the tools used to assess them.

EVIDENCE ACQUISITION

The clinical question was designed using the standard PICOS format. The search complied with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2009 statement and was performed by two independent reviewers.

EVIDENCE SYNTHESIS

Europe, USA, and Thailand favour the penoscrotal technique for vaginoplasty, whereas in the UK, the penile inversion (PI) technique predominates. Primary vaginoplasty using a segment of bowel is less common, and all three techniques have comparable rates of intraoperative rectal injury. The incidence of rectovaginal fistula is reportedly higher in the PI technique. Wound haematoma and vaginal prolapse rates are comparable. Higher rates of clitoral necrosis, urethral meatal stenosis, and wound infection are reported in PI. However, the ability to orgasm, ability to have penetrative sexual intercourse, and satisfaction with aesthetic result are better with PI.

CONCLUSIONS

The evidence for GRS complications and functional outcomes is of low level. Standardised nomenclature reporting of adverse events and robust patient-reported outcome measures (PROMs) are lacking. PROMs are a powerful assessment tool, and standardised definitions of adverse events and functional outcomes should be a priority of future research.

PATIENT SUMMARY

We looked at all studies published on genital reconstructive surgery from 1950 to the present day. We assessed each surgical technique and their associated complication rates, sexual and urinary function outcomes, and how they were reported. We found the evidence to be low and weak. We suggest more robust ways of reporting complications, and the impact on patients' quality of life should be investigated.

Desenvolvimento de um guia rápido para prática de atenção à saúde da população transgênero

Problema: Os direitos fundamentais das pessoas transgênero são negados cotidianamente. Neste cenário, o preconceito age como determinante social de saúde impactando na prevalência de problemas como saúde mental e infecções sexualmente transmissíveis (ISTs). O objetivo foi o desenvolvimento de um sumário de evidências para apoiar o atendimento clínico e embasar a capacitação dos profissionais da Atenção Primária de Saúde de Florianópolis - SC, a fim de melhorar os resultados de saúde dessa população. Métodos: Baseado na ferramenta PACK – interface acessível e intuitiva no modelo pergunte, solicite, aconselhe e trate – já implementada no município de Florianópolis. O método de revisão rápida foi utilizado para busca de evidência, priorizando sumários de prática clínica e protocolos internacionais. Fontes primárias foram utilizadas quando os dados anteriores eram insuficientes ou conflitantes. As perguntas de pesquisa seguiram o acrônimo PICO e a recomendação foi classificada de acordo com a adaptação GRADE do Center of Excellence for Transegender Health. Resultados: Foi criado o Guia Rápido para Prática de Atenção à Saúde da População Transgênero aos moldes do PACK Brasil. O mesmo aguarda aprovação do PACK Brasil e do Ambulatório de Atenção Integral à População Transexual de Florianópolis para futura incorporação do material. Conclusão: Apesar da falta de evidência de qualidade e estudos voltados para a população específica, a existência de diretrizes nesse campo legitima a necessidade de atenção à saúde transgênero, além de auxiliar profissionais de saúde e formuladores de políticas sobre como atender a essas necessidades. Na perspectiva de redução de danos, devemos transpor a barreira do estigma social e institucional para produção de diretrizes consensuais em busca de equidade para população transgênero.

'#WontBeErased': The effects of (de)pathologisation and (de)medicalisation on the legal capacity of trans* persons

Over the last decade, trans* issues have increasingly gained attention all around the globe. While this increased social recognition has mostly resulted in higher acceptance rates of gender non-conformity, world-wide data show that trans* persons still remain among the most vulnerable groups in society. One of the most pressing issues facing trans* persons, is their inherent psycho-pathologisation and medicalisation in society and law. Indeed, in modern history, trans* issues have been predominantly addressed through the lens of medicine and psychiatry, which has had a clear impact on the legal capacity of gender non-conforming persons. Although this contribution shows that a human rights movement towards depathologisation and demedicalisation of gender non-conformity is rapidly getting up steam in several parts of the world, it needs to be questioned whether the current human rights approach is getting it 'right'. In this regard, it is argued that the present focus on trans* depathologisation and demedicalisation should only be the first step towards the full inclusion of all trans* persons in law and society.

Epidemiology of gender dysphoria and transgender identity

This review provides an update on the epidemiology of gender dysphoria and transgender identity in children, adolescents and adults. Although the prevalence of gender dysphoria, as it is operationalised in the fifth edtion of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), remains a relatively 'rare' or 'uncommon' diagnosis, there is evidence that it has increased in the past couple of decades, perhaps reflected in the large increase in referral rates to specialised gender identity clinics. In childhood, the sex ratio continues to favour birth-assigned males, but in adolescents, there has been a recent inversion in the sex ratio from one favouring birth-assigned males to one favouring birth-assigned females. In both adolescents and adults, patterns of sexual orientation vary as a function of birth-assigned sex. Recent studies suggest that the prevalence of a self-reported transgender identity in children, adolescents and adults ranges from 0.5 to 1.3%, markedly higher than prevalence rates based on clinic-referred samples of adults. The stability of a self-reported transgender identity or a gender identity that departs from the traditional male-female binary among non-clinic-based populations remains unknown and requires further study.

Size and Distribution of Transgender and Gender Nonconforming Populations: A Narrative Review

Accurate estimates of the number and proportion of transgender and gender nonconforming people in a population are necessary for developing data-based policy and for planning and funding of health care delivery and research. The wide range of estimates reported in the literature is attributable primarily to differences in definitions. Other sources of variability include diverse cultural and geographic settings and important secular trends. The transgender and gender nonconforming population is undergoing rapid changes in size and demographic characteristics. More accurate and precise estimates will be available when population censuses collect data on sex assigned at birth and gender identity.

Gender-Affirming Hormone Therapy for Transgender Men

There are an estimated 1.4 million transgender adults in the United States, and lack of providers knowledgeable in transgender care is a barrier to health care. Obstetricians and Gynecologists can help increase access in part by becoming competent in gender-affirming hormone therapy. For transgender men, testosterone protocols can be extrapolated from those used for hypogonadal cisgender men. Unfortunately, there are not any high-quality, long-term prospective studies on the effectiveness and safety of different testosterone regimens specifically in transgender men, but the available data suggest that gender-affirming testosterone therapy is safe and effective with proper screening and monitoring.

Sperm cryopreservation of transgender individuals: trends and findings in the past decade

OBJECTIVES

Awareness and acceptance of transgenderism have increased in the last two decades. There is limited literature regarding the incidence and semen characteristics of transwomen banking spermatozoa. We sought to assess the incidence of sperm cryopreservation of transgender individuals compared with the cisgender population in the last 10 years. Semen parameters were also compared between the two groups.

MATERIALS AND METHODS

We performed a retrospective analysis of sperm cryopreservation performed at a single center from 2006 through 2016. Using available data on indications for banking and prior hormonal therapy status, we isolated healthy transgender and cisgender cohorts for semen parameter comparison. Linear regression was used to compare the incidence trends. Semen parameters were compared using the generalized estimating equations method. The rates of semen parameter abnormality of each group were compared using chi-square test. Semen parameter abnormalities were defined using WHO 2010 reference values.

RESULTS

We analyzed 194 transgender samples and 2327 cisgender samples for a total of 84 unique transgender sperm bankers and 1398 unique cisgender sperm bankers. The number of transgender sperm bankers increased relative to cisgender sperm bankers from 2006 to 2016. Following exclusion of cisgender sperm bankers with health issues that might impact semen quality and transgender sperm bankers with known prior hormonal therapy, we compared the semen parameters of 141 healthy cisgender sperm bankers and 78 healthy transgender sperm bankers. The transgender sperm bankers demonstrated lower sperm concentration, total motile sperm count, and post-thaw sperm parameters. The transgender sperm bankers also demonstrated a higher incidence of oligozoospermia.

CONCLUSIONS

This is the largest report to date on the incidence of transgender sperm cryopreservation and comparison of semen characteristics with cisgender sperm bankers. The data reveal an increased incidence of transgender sperm banking as well as poorer semen parameters of transgender individuals compared with cisgender controls.

Novel surgical techniques in female to male gender confirming surgery

The current management of female to male (FTM) gender confirmation surgery is based on the advances in neo phalloplasty, perioperative care and the knowledge of the female genital anatomy, as well as the changes that occur to this anatomy with preoperative hormonal changes in transgender population. Reconstruction of the neophallus is one of the most difficult elements in surgical treatment of female transsexuals. While there is a variety of available surgical techniques, their results are not equally acceptable to all patients. The preference for a particular surgical technique mostly depends on the patient's desires and expectations. Nevertheless, the surgeon's duty is to fully inform the patient about all the advantages and disadvantages, as well as all complications that might occur after surgical procedure-and even to talk them out of a desired surgical technique if there are contraindications. Metoidioplasty is a technically demanding surgical procedure used in FTM transsexuals who desire a gender reassignment surgery (GRS) without undergoing a complex, multi-staged surgical creation of an adult-sized phallus. Metoidioplasty is viable in cases where the clitoris seems large enough after androgen hormonal treatment. Since the clitoris plays the main role in female sexual satisfaction, its impact on the outcome of FTM transgender surgery is predictable. Various free flaps have been reported for total phalloplasty, such as radial forearm flap, latissimus dorsi flap, anterolateral tight flap, different abdominal wall flaps, free deltoid flap, scapular free flap, sensate osteocutaneous free fibula flap, tensor fasciae latae, deep epigastric artery perforator flap and dorsalis pedis flap. The fact that there are so many techniques for penile reconstruction in cases of penis absence, proves that none of the above mentioned techniques succeeded in achieving the ideal goals of penis reconstruction. We will emphasize the most commonly used surgical techniques in genital confirmation in FTM transsexuals with reference to respective eligibility criteria for each procedure.

Online Patient Resources for Gender Affirmation Surgery: An Analysis of Readability

BACKGROUND

Gender affirmation surgery is an important treatment for patient with gender dysphoria. It consists of a series of complex procedures, and well-informed patients have been shown to have better outcomes. However, there are no published data regarding the readability of currently available online patient recourses for gender affirmation surgery. This study aims at identifying the most popular online resources and evaluating the readability of these documents in the context of average literacy within the United States.

METHODS

An online search with the terms "gender affirmation surgery," "gender reassignment surgery," "top surgery," and "bottom surgery" was performed. Location, cookies, and user account information was disabled before each search to avoid bias in the results. Readability assessment was performed using the 10 commonly used readability scales.

RESULTS

The overall mean readability level was 13.4. The mean reading level was 14 (range, 7.6-17.0) for the search term "gender affirmation surgery," 14.2 (range, 11.9-16.7) for the search term "gender reassignment surgery," 13 (range, 8.9-17.5) for the search term "top surgery," and 12.6 (range, 7.1-15.0) for the search term "bottom surgery." There was no statistically significant difference between the search terms.

CONCLUSIONS

Our findings demonstrate that the articles most commonly seen by patients who perform an Internet search for information on gender reassignment surgery are more difficult than the recommended readability level.

Gender Dysphoria in Adults: An Overview and Primer for Psychiatrists

Regardless of their area of specialization, adult psychiatrists are likely to encounter gender-variant patients; however, medical school curricula and psychiatric residency training programs devote little attention to their care. This article aims to assist adult psychiatrists who are not gender specialists in the delivery of respectful, clinically competent, and culturally attuned care to gender-variant patients, including those who identify as transgender or transsexual or meet criteria for the diagnosis of Gender Dysphoria (GD) as defined by The Diagnostic and Statistical Manual of Mental Disorders (5th edition). The article will also be helpful for other mental health professionals. The following areas are addressed: evolution of diagnostic nosology, epidemiology, gender development, and mental health assessment, differential diagnosis, treatment, and referral for gender-affirming somatic treatments of adults with GD.

Attachment Patterns and Complex Trauma in a Sample of Adults Diagnosed with Gender Dysphoria

The current study investigated attachment representations and complex trauma in a sample of gender dysphoric adults. Although it has been proven that the psychological wellbeing of gender diverse persons is largely mediated by family acceptance and support, research on their relationships with parental figures is scarce. A total of 95 adults took part in the study. The attachment distribution was as follows: 27% secure, 27% insecure and 46% disorganized. Regarding early traumas, 56% experienced four or more traumatic forms. Further, gender dysphoric adults showed significantly higher levels of attachment disorganization and polyvictimisation, relative to controls. Comparisons of subgroups, defined by natal gender, showed that trans women, compared to control males, had more involving and physically and psychologically abusive fathers, and were more often separated from their mothers; trans men, relative to female controls, had more involving mothers and were more frequently separated from and neglected by their fathers. The research has several implications for treatment, clinical health psychology, family support and education.

The risky womb and the unthinkability of the pregnant man: Addressing trans masculine hysterectomy

In April 2017, the European Court of Human Rights ruled that requiring trans people to undergo sterilisation in order to grant legal gender recognition was a breach of human rights. In the UK, sterilisation has never been a legal requirement for trans people. However, hysterectomy and salpingo-oopherectomy have been strongly encouraged for trans masculine people on medical grounds, although the clinical evidence for current recommendations is weak. Within this article I analyse the issue from a feminist perspective and argue that current presumptions in favour of surgical intervention are influenced by the history of medical interventions to “fix” bodies perceived as female, coupled with a strong social taboo against the pregnant man. As a consequence, medical and legal frameworks are not necessarily facilitating optimal outcomes for the individual. I suggest that practices in this regard should be critically examined, with a view to developing more tailored, person-centred practices and facilitating informed choice.

Genital reconstruction for the transgendered individual

INTRODUCTION

Gender dysphoria is defined as one's belief that his/her body does not reflect his/her true "inner" identification of physical sex and requires medical and/or surgical treatment that will alter his/her body to better reflect what he/she believes is his/her true gender.

OBJECTIVE

The aim was to describe current surgical techniques available in genital reconstruction for female-to-male (FTM) and male-to-female (MTF) transgender patients.

STUDY DESIGN

We reviewed recently published papers concerning the most common procedures in genital reconstruction in FTM transgenders and in MTF transgenders.

RESULTS

There is a wealth of available surgical procedures for FTM transgenders that will adjust their body and genitals toward the male gender. Chest masculinization combined with either metoidioplasty or phalloplasty are the most common procedures resulting in high patient satisfaction. Standardization of the procedures for vaginoplasty in MTF transgenders led to the penile inversion skin technique becoming a "gold standard" for vaginal lining in MTF patients, providing satisfying functional and esthetical outcome of the surgery. In extreme cases of shortage of skin, or when a vaginoplasty has failed, a vaginal lining can be created from hairless skin grafts, or a section of intestine may be used (bowel vaginoplasty).

CONCLUSION

A multidisciplinary approach including psychiatrists, psychologists, plastic surgeons, urologists, and gynecologists is the only effective treatment in transgenders. The surgeons' familiarity with the surgical procedure and the patients' desired body images should meet at the same level to guarantee a successful outcome.

Male-to-Female Sex Reassignment Surgery Using the Combined Technique Leads to Increased Quality of Life in a Prospective Study

BACKGROUND

The authors' previous research showed that various plastic surgical procedures can increase a patient's quality of life in its different aspects. In a prospective setting, they evaluated whether sex reassignment surgery has similar effects for male-to-female transgender patients compared to baseline data before sex reassignment surgery.

METHODS

All 39 patients who underwent their first-stage male-to-female sex reassignment surgery between October of 2012 and January of 2014 received one set of questionnaires preoperatively (time 0) and approximately 6 months after their final operation (time 1). Each set contained self-developed, indication-specific questions combined with the standardized validated Questions on Life Satisfaction, Modules (German version) questionnaire, the Freiburg Personality Inventory, the Rosenberg Self-Esteem Scale, and the Patient Health Questionnaire, which were compared to available norm data.

RESULTS

The mean patient age was 38.6 years. The majority of the patients were highly educated, childless, and single. Significant improvements were found in the Questions on Life Satisfaction, Modules (German version), especially for the items "partnership," "ability to relax," "energy," "freedom from anxiety," "hair," "breast," and "penis/vagina" (p < 0.01). Furthermore, the patients appeared more emotionally stable (p = 0.03), showed higher self-esteem (p = 0.01), and showed much lower depression/anxiety (p < 0.01).

CONCLUSIONS

The positive study findings were confirmed with the results from prior retrospective studies. However, medical literature focuses largely on surgical and functional satisfaction and not overall quality of life. In addition, standardized questionnaires are used rarely and solely retrospectively, with the risk of recall bias. The increased quality of life of transgender women postoperatively endorses sex reassignment surgery as a valuable option for these patients.

Needs and concerns of transgender individuals regarding interdisciplinary transgender healthcare: A non-clinical online survey

This study investigates the needs and concerns transgender (short: trans) individuals have concerning trans healthcare (THC) in interdisciplinary THC centres. Trans individuals' gender does not (fully/constantly) match their sex assigned at birth. To be able to live in their gender role and to prevent or minimise gender dysphoria, they might require a multidisciplinary set of transition related healthcare services. The current shift from the traditionally highly regulated, hierarchical and pathologising approach to THC towards a more patient-centred approach has highlighted the importance of trans patients' satisfaction with treatment processes and results. As the still influential regulations have a negative effect on patient satisfaction, and might also keep trans individuals from seeking transition related treatment, it is crucial to investigate what trans individuals, whether patients or not, need and fear regarding transition related healthcare. Against the backdrop of mixed reactions received from the local trans community regarding the foundation of the Interdisciplinary Transgender Healthcare Centre Hamburg (ITHCCH), Germany, this study seeks to determine what trans individuals need with respect to THC in order to guarantee for high quality service provision at the ITHCCH. To this end, an online questionnaire was developed. The researchers employed a participatory approach to questionnaire development by involving a working group consisting of local trans support group representatives and (THC) specialists (N = 4). The sample consisted of N = 415 trans-identified individuals aged between 16 and 76. Most of them were based in Germany. 85.2% (n = 382) reported experience with transition related healthcare and 72.5% (n = 301) had (additional) treatments planned. Analysis revealed a need for communication and feedback opportunities. Furthermore, during the treatment process, addressing individual needs was considered crucial by participants. They agreed moderately with concerns towards THC centres. 96.5% of participants would like high decision-making power concerning treatment-associated decisions. The results demonstrate the importance of patient-centred THC that takes patients' individual needs and realities into consideration and involves patients in decision-making processes.

Efficacy of hormonal and mental treatments with MMPI in FtM individuals: cross-sectional and longitudinal studies

BACKGROUND

Cross-sex hormone treatment (CSHT) is an important option for gender dysphoria (GD) individuals to improve the quality of life. However, in Japan, sex reassignment surgery (SRS) and CSHT for GD had been discontinued until 1998 (over 30 years). After resumption, the number of GD individuals wishing treatment rapidly increased. On the other hand, the number of medical institutions available for evaluation was limited. For this reason, hormonal treatment has been administered to GD individuals requiring the prompt start of CSHT in the absence of mental health assessment by specialists. In this study, we examined the efficacy of CSHT and psychotherapy.

METHODS

The participants were 155 female-to-male (FtM) individuals who consulted our gender identity clinic, and were definitively diagnosed. A cross-sectional study was conducted by dividing them into two groups: groups with and without CSHT on the initial consultation (Group CSHT: n = 53, Group no-CSHT: n = 102). In all participants, Minnesota Multiphasic Personality Inventory (MMPI) and blood hormone tests were performed on the initial consultation. In addition, CSHT was combined with psychotherapy for a specific period in Group no-CSHT, and FtM individuals in whom an additional MMPI test could be conducted (Group combined treatment (CT), n = 14) were enrolled in a longitudinal study.

RESULTS

In the cross-sectional study, there was no significant difference on the MMPI test. In the longitudinal study, there were improvements in the clinical scales other than the Mf scale on the MMPI test. In Group CT, the D, Sc, and Si scale scores on the initial consultation were significantly higher than in Group CSHT. However, there was no clinical scale with a significantly higher value after the start of treatment. The Pd scale score was significantly lower.

CONCLUSIONS

CSHT improved mental health. Psychotherapy-combined CSHT may further improve it.

TRIAL REGISTRATION

The study was reviewed and approved by the Ethics Committee of Kansai Medical University (A comprehensive treatment for gender dysphoria: No. 0314 registered date 10th December 2003), and was approved at UMIN000028102 on 6th July 2017 as retrospectively registered.

When Gender Identity Doesn't Equal Sex Recorded at Birth: The Role of the Laboratory in Providing Effective Healthcare to the Transgender Community

BACKGROUND

Transgender is an umbrella term used to describe individuals who identify with a gender incongruent to or variant from their sex recorded at birth. Affirming gender identity through a variety of social, medical, and surgical interventions is critical to the mental health of transgender individuals. In recent years, awareness surrounding transgender identities has increased, which has highlighted the health disparities that parallel this demographic. These disparities are reflected in the experience of transgender patients and their providers when seeking clinical laboratory services.

CONTENT

Little is known about the effect of gender-affirming hormone therapy and surgery on optimal laboratory test interpretation. Efforts to diminish health disparities encountered by transgender individuals and their providers can be accomplished by increasing social and clinical awareness regarding sex/gender incongruence and gaining insight into the physiological manifestations and laboratory interpretations of gender-affirming strategies. This review summarizes knowledge required to understand transgender healthcare including current clinical interventions for gender dysphoria. Particular attention is paid to the subsequent impact of these interventions on laboratory test utilization and interpretation. Common nomenclature and system barriers are also discussed.

SUMMARY

Understanding gender incongruence, the clinical changes associated with gender transition, and systemic barriers that maintain a gender/sex binary are key to providing adequate healthcare to transgender community. Transgender appropriate reference interval studies are virtually absent within the medical literature and should be explored. The laboratory has an important role in improving the physiological understanding, electronic medical system recognition, and overall social awareness of the transgender community.

Prevalence, Incidence, and Sex Ratio of Transsexualism in the Autonomous Region of Madrid (Spain) According to Healthcare Demand

In recent years, different studies have provided estimates of the prevalence of transsexualism with very diverse results. The purpose of this study was to ascertain the prevalence, incidence, and sex ratio of transsexualism in the autonomous region of Madrid (Spain). A total of 1234 patients who attended from 2007 to the end of 2015 in the only Gender Identity Unit (GIU) in Madrid were analyzed. Sixty-three patients were excluded for various reasons; thus, 1171 could be included: 803 male-to-female (MtF) and 368 female-to-male (FtM) transsexual patients. Transsexualism was diagnosed based on the ICD-10, World Health Organization, 1992, and/or gender identity disorder based on the DSM-IV-TR, American Psychiatric Association, 2000. The demographic statistics were calculated on the basis of the population over 15 years old of Madrid. Based on healthcare demand, the prevalence of transsexualism was 22.1 in 100,000 inhabitants: 31.2 for MtF and 12.9 for FtM, making the MtF/FtM ratio approximately 2.2:1. The incidence rate was 2.5 in 100,000 inhabitants, representing an annual average of 130 demands. Although transsexualism occurs in all countries with different rates of prevalence, in our area, this prevalence was higher than reported from other European countries. We believe that two main circumstances might influence this high prevalence: the easy accessibility and the absence of a waiting list to the GIU, and the permissive social and legal climate and openness of Spain, especially in Madrid.

Transgender Population Size in the United States: a Meta-Regression of Population-Based Probability Samples

BACKGROUND

Transgender individuals have a gender identity that differs from the sex they were assigned at birth. The population size of transgender individuals in the United States is not well-known, in part because official records, including the US Census, do not include data on gender identity. Population surveys today more often collect transgender-inclusive gender-identity data, and secular trends in culture and the media have created a somewhat more favorable environment for transgender people.

OBJECTIVES

To estimate the current population size of transgender individuals in the United States and evaluate any trend over time.

SEARCH METHODS

In June and July 2016, we searched PubMed, Cumulative Index to Nursing and Allied Health Literature, and Web of Science for national surveys, as well as "gray" literature, through an Internet search. We limited the search to 2006 through 2016.

SELECTION CRITERIA

We selected population-based surveys that used probability sampling and included self-reported transgender-identity data.

DATA COLLECTION AND ANALYSIS

We used random-effects meta-analysis to pool eligible surveys and used meta-regression to address our hypothesis that the transgender population size estimate would increase over time. We used subsample and leave-one-out analysis to assess for bias.

MAIN RESULTS

Our meta-regression model, based on 12 surveys covering 2007 to 2015, explained 62.5% of model heterogeneity, with a significant effect for each unit increase in survey year (F = 17.122; df = 1,10; b = 0.026%; P = .002). Extrapolating these results to 2016 suggested a current US population size of 390 adults per 100 000, or almost 1 million adults nationally. This estimate may be more indicative for younger adults, who represented more than 50% of the respondents in our analysis.

AUTHORS' CONCLUSIONS

Future national surveys are likely to observe higher numbers of transgender people. The large variety in questions used to ask about transgender identity may account for residual heterogeneity in our models. Public health implications. Under- or nonrepresentation of transgender individuals in population surveys is a barrier to understanding social determinants and health disparities faced by this population. We recommend using standardized questions to identify respondents with transgender and nonbinary gender identities, which will allow a more accurate population size estimate.

PREVALENCE AND TYPES OF GENDER-AFFIRMING SURGERY AMONG A SAMPLE OF TRANSGENDER ENDOCRINOLOGY PATIENTS PRIOR TO STATE EXPANSION OF INSURANCE COVERAGE

OBJECTIVE

Transgender individuals now have many options for medical intervention, including gender-affirmation surgeries. However, it is unknown how common it is for transgender individuals to undergo these surgeries. The purpose of this cross-sectional study was to assess the prevalence of gender-affirming surgeries among transgender patients in 2015, which was immediately prior to insurance changes that made gender-affirming surgery more affordable for Massachusetts residents.

METHODS

A retrospective chart review of 99 transgender patients was performed at the Endocrinology Clinic at Boston Medical Center, an urban safety net hospital. The records for 99 transgender subjects who received treatment between 2004-2015, including 28 transmen and 71 transwomen, were examined. The outcome measures were the types of medical interventions chosen by transgender patients, which included hormone therapy, chest surgery, gonadectomy, genital surgery, and facial surgery.

RESULTS

Thirty-five percent of subjects had undergone at least one gender-affirming surgery. Transmen were more likely to have had surgery than transwomen (54% vs. 28%). Twenty-five percent of patients had chest surgery, 13% had genital surgery or gonadectomy, and 8% had facial surgery.

CONCLUSION

In 2015, a majority of transgender endocrinology clinic patients had not undergone any type of gender-affirmation surgery. Among those who did elect to have a surgery, genital surgery or gonadectomy were uncommon. The low rate of surgery among this sample of transgender patients may be attributable to the financial cost, lack of interest in surgery, or that genital surgery is not a high priority for transgender individuals relative to surgery to change visible features such as face and chest. Abbreviation: HT = hormone therapy.

Breast Cancer Suspicion in a Transgender Male-to-Female Patient on Hormone Replacement Therapy Presenting with Right Breast Mass: Breast Cancer Risk Assessment and Presentation of a Rare Lesion

There has been an increasing use of hormonal therapy among male-to-female (MtF) transgender individuals. This long-term hormone replacement therapy (HRT) renders MtF individuals a unique patient subgroup in terms of breast cancer risk. This case describes a MtF transgender who presented with a breast lesion concerning for malignancy following hormonal replacement therapy. The patient additionally had a strong family history of breast cancer. Final pathology revealed lobular hyperplasia in the setting of gynecomastia and pseudoangiomatous stromal hyperplasia (PASH). Both pathology findings are rare in biological females, let alone in the setting of hormone replacement therapy in a MtF individual. While the number of reported cases of suspicious breast lesions in this population remains scarce, it presents both a diagnostic and therapeutic challenge due to the nature of the treatment course and the lack of research in this recently growing subgroup of patients.
