Endocrine treatment of transsexual persons: an Endocrine Society clinical practice guideline

Association between serum estradiol and cardiovascular health among transgender adults using gender-affirming estrogen therapy

Gender-affirming estrogen therapy (GAET) is commonly used for feminization in transgender and nonbinary (TNB) individuals, yet the optimal rate of change (ROC) in estradiol levels for cardiovascular health is unclear. We examined the association between serum estradiol levels and cardiovascular-related mortality, adverse events, and risk factors in TNB adults using GAET. Cochrane Central Register of Controlled Trials, EMBASE, MEDLINE, and Web of Science were systematically searched (inception-April 2023) for original articles reporting serum estradiol levels and cardiovascular-related mortality, adverse events, and risk factors in TNB adults using GAET. Data extraction was completed in duplicate following Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Stratified random effect meta-analyses using serum estradiol ROC (serum estradiolbaseline - serum estradiolfollow-up/study duration) was used to assess longitudinal studies (low, 0 < ROC ≤ 1 pg/mL/mo; moderate, 1 < ROC ≤ 3 pg/mL/mo; high, ROC ≥ 3 pg/mL/mo). Thirty-five studies (13 cross-sectional, 19 cohort, and 3 trials) were included. Two studies collectively reported 50 cardiovascular-related deaths, and four collectively reported 23 adverse cardiovascular events. Nineteen studies reporting cardiovascular risk factors were meta-analyzed by ROC stratum (low = 5; moderate = 6; high = 8), demonstrating an association between moderate [0.40, 95% confidence interval (CI): 0.22, 0.59 kg/m2, I2 = 28.2%] and high (0.46, 95% CI: 0.15, 0.78 kg/m2; I2 = 0.0%) serum estradiol ROC and increased body mass index. High (-6.67, 95% CI: -10.65, -2.68 mg/dL; I2 = 0.0%) serum estradiol ROC was associated with decreased low-density lipoproteins. Low (-7.05, 95% CI: -10.40, -3.70 mmHg; I2 = 0.0%) and moderate (-3.69, 95% CI: -4.93, -2.45 mmHg; I2 = 0.0%) serum estradiol ROCs were associated with decreases in systolic blood pressure. In TNB adults using GAET, serum estradiol ROC may influence cardiovascular risk factors, which may have implications for clinical cardiovascular outcomes.NEW & NOTEWORTHY In this systematic review and meta-analysis of 35 studies involving 7,745 participants, high rates of serum estradiol change were associated with small increases in body mass index. Moderate to high rates of change were associated with decreases in low-density lipoprotein. Low rates of change were associated with small decreases in systolic blood pressure. Rate of serum estradiol change in adults using gender-affirming estrogen therapy may influence cardiovascular risk factors, though further research is warranted.

Body composition and risk for sarcopenia in transgender women

OBJECTIVES

Body composition and strength of cisgender (cis) individuals are well established. However, those for transgender women (trans women) undergoing gender-affirming hormone therapy remain unclear. This study aimed to detect possible body composition and strength variations related to sarcopenia.

METHODS

This was a cross-sectional comparative study of 37 trans women, 34 cis men, and 34 cis women. Body composition was measured in all individuals by bioelectrical impedance analysis; prehensile strength by dynamometry was studied in trans women.

RESULTS

In this study, trans women had higher body mass index values than cis individuals (P < 0.01). Fat mass was 41% higher for trans women than cis men. Muscle mass (MM) was lower in trans women than cis men (-10%), and higher than cis women (24%). Bone mass was lower in trans women than cis men and higher in cis women (P < 0.01). Trans women's prehensile strengths were 25.26 kg for the right hand and 24.8 kg for the left. Appendicular skeletal muscle mass was 23.63 kg, and appendicular skeletal muscle mass index was 8.14 kg.

CONCLUSION

Trans women undergoing gender-affirming hormone therapy show a tendency to adapt body compartments to those of cis women with increased fat mass and reduced muscle mass. Prehensile strength in trans women was close to the cutoff points for sarcopenia risk. Nutrition, physical activity, strength, and body composition are important to avoid the possible risk for sarcopenia. More studies along these lines are necessary, especially in older adults.

Testosterone and other treatments for transgender males and non-binary trans masculine individuals

Testosterone therapy is the main hormonal treatment offered in transmen to alleviate somatic gender dysphoria. Testosterone can be administered via topical or injectable preparations to achieve physical changes resulting in masculinisation and improve quality of life for the treated individuals. The aim of our paper is to outline methods for testosterone replacement, their impact on main body systems of transmen, potential associated health risks and long term follow up. Androgen use in transgender medicine is safe with appropriate endocrine guidance and monitoring. Studies with longer follow-up period, including those who may prefer low dose testosterone, interested in pregnancy or older people may further improve the management of female-to-male transgender persons.

Biochemical liver damage during gender affirming therapy in trans adults assigned female at birth: a meta-analysis

PURPOSE

To assess the effects of testosterone (T)-based gender affirming hormone therapy (GAHT) on liver blood tests (LBTs) in assigned female at birth adults, using a meta-analytic approach.

METHODS

Prospective and retrospective studies were selected that reported the prevalence of biochemical liver damage (BLD) and LBTs changes during T therapy. Data collected included pre-and-during therapy alanine-aminotransferase (ALT), aspartate-aminotransferase (AST), gamma-glutamyl-transferase (GGT), and alkaline phosphatase (ALP) mean concentration values.

RESULTS

The prevalence of BLD in 14 studies on 1698 subjects was 1% (95% CI 0.00-3.00; I2 = 14.1%; p = 0.82). In 17 studies on 2758 subjects, GAHT was associated with a statistically (but not clinically) significant increase in AST, GGT and ALP at 12 months and ALT at 3-7 (MD: 1.19 IU/l; 95% CI 0.31, 2.08; I2: 0%), at 12 (MD: 2.31 IU/l; 95% CI 1.41, 3.21; I2: 29%), but with no more significant increase at 24 months (MD: 1.71 IU/l; 95% CI -0.02, 3.44; I2: 0%).

CONCLUSIONS

Analysis of aggregate estimates confirms a low risk of BLD and abnormalities in LBTs, transient in most cases, during T-based GAHT, thus suggesting a limited need for careful liver monitoring in AFAB people.

Maximizing surgical outcomes with gender affirming hormone therapy in gender affirmation surgery

Gender Affirmation Surgery (GAS) is a super specialized subset within the field of plastic and reconstructive surgery (PRS) that is ever evolving and of increasing interest to the PRS community. It is a multifaceted process which, in addition to surgical therapy, involves mental health therapy and hormonal therapy. One rapidly emerging interest within GAS is the role that gender affirming hormone therapy (GAHT) plays in enhancing surgical outcomes. GAHT has been used adjunctively with GAS as a comprehensive therapy to ameliorate gender dysphoria. This literature review will examine the positive effects of GAHT on the surgical outcomes on GAS, as well as other important considerations prior to surgery. As such, the primary objective of this literature review is to evaluate and assess the current evidence concerning the efficacy and safety of GAHT, as it relates to Gender Affirmation Surgery procedures.

Changes in Gender Dysphoria, Interpersonal Minority Stress, and Mental Health Among Transgender Youth After One Year of Hormone Therapy

PURPOSE

Cross-sectional studies have identified a strong link between interpersonal minority stress and mental health among transgender youth. However, very little is known about how experiences of minority stress change over time and how these changes relate to mental health. Further, few quantitative studies have examined the extent to which changes in gender dysphoria drive the improvements witnessed in mental health following gender-affirming medical treatment.

METHODS

Transgender youth (N = 115; age 12-18) completed measures of interpersonal minority stress (e.g., family and peer support, parent support of gender, victimization), body dissatisfaction, and mental health (e.g., depression, anxiety, psychosocial functioning) at baseline and one year after initiating medical treatment with a multidisciplinary gender-affirming program.

RESULTS

Significant reductions in body dissatisfaction, victimization, depression, and anxiety were found along with improvements in parent gender-related nonaffirmation and psychosocial functioning. Higher levels of baseline family support, parent gender-related acceptance, and lower levels of baseline victimization were associated with better mental health at one-year follow-up. Reductions in body dissatisfaction were also associated with fewer symptoms of depression and better psychosocial functioning and follow-up.

DISCUSSION

Results provide further confirmation of the broad, short-term benefits of gender-affirming hormone therapy and highlight the importance of monitoring youth's experience of dysphoria while receiving treatment. Results also continue to highlight the importance of family support and suggest some forms of minority stress improve over time; however, the relationship between short-term changes in minority stress and mental health may be more complex.

The association of gender-affirming hormone therapy duration and body mass index on bone mineral density in gender diverse adults

Introduction

Feminizing and masculinizing gender-affirming hormone therapy (fGAHT, mGAHT) results in bone mineral density (BMD) maintenance or improvement over time in transgender and gender diverse (TGD) adults. Mostly European TGD studies have explored GAHT's impact on BMD, but the association of BMI and BMD in TGD adults deserves further study.

Objective

To determine whether GAHT duration or BMI are associated with BMD and Z-scores among TGD young adults.

Methods

Cross-sectional study of nonsmoking TGD adults aged 18-40 years without prior gonadectomy or gonadotropin-releasing hormone agonist (GnRHa) therapy taking GAHT for > 1 year. BMD and Z-scores were collected from dual-energy x-ray absorptiometry. Associations between femoral neck, total hip, and lumbar spine BMDs and Z-scores and the predictors, GAHT duration and BMI, were estimated using linear regression.

Results

Among 15 fGAHT and 15 mGAHT, mean BMIs were 27.6 +/- standard deviation (SD) 6.4 kg/m2 and 25.3 +/- 5.9 kg/m2, respectively. Both groups had mean BMDs and Z-scores within expected male and female reference ranges at all three sites. Higher BMI among mGAHT was associated with higher femoral neck and total hip BMDs (femoral neck: β = 0.019 +/- standard error [SE] 0.007 g/cm2, total hip: β = 0.017 +/- 0.006 g/cm2; both p < 0.05) and Z-scores using male and female references. GAHT duration was not associated with BMDs or Z-scores for either group.

Conclusions

Z-scores in young, nonsmoking TGD adults taking GAHT for > 1 year, without prior gonadectomy or GnRHa, and with mean BMIs in the overweight range, were reassuringly within the expected ranges for age based on male and female references. Higher BMI, but not longer GAHT duration, was associated with higher femoral neck and total hip BMDs and Z-scores among mGAHT. Larger, prospective studies are needed to understand how body composition changes, normal or low BMIs, and gonadectomy affect bone density in TGD adults.

Treatment trajectories of gender incongruent Austrian youth seeking gender-affirming hormone therapy

Objective

The aim of this study was to describe the treatment trajectories of Austrian children and adolescents with gender incongruence seeking gender-affirming medical care.

Methods

Patients who presented with gender incongruence at the pediatric outpatient clinic for differences in sex development at a large university hospital in Austria from January 2008 to December 2022 were included in a retrospective chart review, and analyzed regarding referral numbers, patient characteristics, treatment trajectories, fertility preservation, and legal gender marker changes.

Results

Of 310 eligible patients, 230 (74.2%) were assigned female at birth (AFAB), and 80 (25.8%) were assigned male at birth (AMAB). The number of referrals increased steeply from 2008 to 2018, whereafter it stabilized at around 50 per year. At the time of initial presentation, the median age of patients was 15.6 years (IQR 14.3-16.8). AMAB individuals tended to be younger (median 14.9 years, IQR 13.9-16.8) than AFAB individuals (median 15.8 years, IQR 14.4-16.8; p= 0.012). 207 (66,8%) completed the assessment process and were eligible for gender affirming medical treatment (GAMT). Of those, 89% (186/207) commenced gender affirming hormone therapy in the pediatric outpatient clinic (79/186 received GnRHa monotherapy, 91/186 GnRHa and sex steroids, and 16/186 sex steroid monotherapy). Of the 54 AMAB individuals receiving GAMT, 6 (11.1%) completed fertility preservation prior to therapy initiation. Only 1/132 AFAB adolescents receiving GAMT completed fertility preservation. Chest masculinization surgery was performed in 22 cases (16.7%), and breast augmentation in two cases (3.7%) between the ages of 16 and 18. Changes in legal gender marker were common, with 205 individuals (66.1%) having changed their legal gender marker.

Conclusion

This is the first time that treatment trajectories, fertility preservation rates, and changes of legal gender marker have been described in Austrian adolescents with gender incongruence seeking GAMT. The majority received GAMT and changed their legal gender marker, while gender affirming surgery rates were low, and utilization of fertility preservation treatment options was rare.

Developmental uterovaginal anomalies and histologic findings in transgender patients receiving gender-affirming hysterectomies: A large case series

OBJECTIVE

To describe the incidence of uterovaginal anomalies and histologic findings in transgender and nonbinary (TGNB) patients seeking hysterectomies.

METHODS

All patients receiving gender-affirming hysterectomies between 2013 and 2023 were retrospectively reviewed. Primary outcomes included uterovaginal anomalies and histological findings. Multivariable logistic regressions were performed to evaluate relationships between variables of interest and whether they predict findings of uterovaginal anomalies, inactive endometrium, adenomyosis, leiomyoma, endometriosis, and cervical atrophy.

RESULTS

278 patients received hysterectomies at an average age of 29.2 ± 8.3 years. Seven patients (2.5%) were found to have a developmental anomaly, including two bicornuate uterus (0.7%), two unicornuate uterus (0.7%), one septate uterus (0.4%), and two vaginal septum (0.7%). 60 patients (21.6%) were found to have inactive endometrium and 26 patients (9.4%) had cervical atrophy. Although 262 patients (94.2%) were on testosterone therapy, hormone duration was not a significant predictor of any uterine findings.

CONCLUSION

This study describes uterovaginal anomalies in a large cohort of patients receiving gender-affirming hysterectomies. Although long-term testosterone use is commonly believed to be associated with endometrial and cervical atrophy, this study shows no such association.

Gender Affirming Facial Surgery-Anatomy and Procedures for Facial Masculinization

For some patients, feminine facial features may cause significant gender dysphoria. Multiple nonsurgical and surgical techniques exist to masculinize facial features. Nonsurgical techniques include testosterone supplementation and dermal fillers. Surgical techniques include soft tissue manipulation, synthetic implants, regenerative scaffolding, or bony reconstruction. Many techniques are derived from experience with cisgender patients, but are adapted with special considerations to differing anatomy between cisgender and transgender men and women. Currently, facial masculinization is less commonly sought than feminization, but demand is likely to increase as techniques are refined and made available.

Breast Cancer Screening Recommendations for Transgender Patients: A Review

Shifting societal attitudes trending toward increased acceptance of transgender people has contributed to a growth in the population of individuals who openly identify as transgender as well as an increase in utilization of gender-affirming surgeries. Therefore, health care providers should work toward increasing their knowledge with respect to the health care needs of the transgender population, particularly given that these individuals often face discrimination in the health care system. Moreover, transgender breast cancer screening rates lag behind breast cancer screening rates for cisgender individuals. We attempt to clarify important terminology about the transgender population and introduce the concept of equity-centered language. We review current transgender breast cancer screening guidelines by using PubMed, Google Scholar, and Google with search terms that included transgender breast cancer guidelines, transgender breast cancer screening guidelines, and transgender cancer screening guidelines. Searches were not filtered based on year of publication, language of publication, or geographic location. We compare the various guidelines as they pertain to both transgender men and transgender women and offer special considerations for upholding inclusivity in the health care field. An easy-to-reference summary of the current transgender breast cancer screening guidelines and the major points of this article were compiled into an original infographic that health care providers can reference to ensure that appropriate care is being offered.

Mental health outcomes and suicidality in hospitalized transgender adolescents: A propensity score-matched Cross-sectional analysis of the National inpatient sample 2016-2018

Transgender adolescents have unique mental health needs. This demographic has increased rates of mood disorders, anxiety, and depression compared to their cisgender peers. Large-scale studies focused on mental health outcomes, including suicidality, in the transgender adolescent population remain unknown. This study tries to fill these gaps in the literature. Data for this study was taken from the National Inpatient Sample 2016-2018. Transgender adolescents were identified using the ICD-10 codes related to transsexualism diagnoses. These individuals were compared to adolescents without transsexualism diagnoses. To mitigate imbalances in baseline characteristics, we utilized a 1:2 nearest neighbor propensity score matching with a caliper width of 0.0001, considering variables such as age, year of hospitalization, and psychiatric disorders. Following propensity score matching, the study cohort comprised 2635 transgender and 5270 non-transgender adolescents (Mean age 15.2 years). The transgender group demonstrated a notably higher prevalence of mood disorders (91%) and anxiety disorders (65%). Furthermore, the prevalence of suicidal ideation was significantly higher in the transgender group (52.4% vs. 39.2%, p < 0.001). However, there was no significant difference in the prevalence of suicide attempts between the groups. After controlling for psychiatric comorbidities, age, and gender, the odds ratio for the composite outcome of suicidal ideation or attempt was 1.99 (95% CI 1.58-2.12, p < 0.001). Our study identifies elevated mood and anxiety disorders and suicidality rates in hospitalized transgender adolescents compared to cisgender peers. Mood disorders notably amplify the risk of suicidal attempts. These findings urgently call for targeted mental health interventions and policy changes to serve this vulnerable population in healthcare settings better.

Patterns of Perioperative Hormone Therapy for Gender-Affirming Surgery

INTRODUCTION

There is no consensus regarding perioperative hormone replacement therapy (HRT) for gender-affirming surgery (GAS). Common concerns for continuing perioperative HRT included risk of deep vein thrombosis (DVT) or hematoma. However, discontinuing HRT is not risk free and may cause mood swing or increased anxiety. Our study aimed to investigate current patterns of HRT before GAS worldwide.

METHODS

The first stage of Delphi technique was implemented by sending a 27-item survey to all surgeons (total n = 150; 94 plastic surgeon, 35 urologist, and 21 gynecologists) of the World Professional Association for Transgender Health who perform GAS. Survey themes included the hormone type, duration, and usage of DVT prophylaxis.

RESULTS

Overall survey response rate was 34% (total n = 51; 8 urologists, 35 plastic surgeons, and 8 gynecologists). The majority of surgeons are US-based (n = 39, 76%). The most common HRTs are in injection form (n = 28, 55%). The majority of surgeons do not stop HRT before GAS and do provide DVT prophylaxis to all patients <1 week after GAS. The most common procedure that surgeons discontinue HRT is feminizing bottom surgery (43%). For surgeons who discontinue HRT before GAS, there is a wide variation on discontinuation schedule.

CONCLUSIONS

There is considerable variation in perioperative HRT patterns for GAS. Further research is needed to develop a data-driven consensus guideline to provide high quality of care for transgender and nonbinary patients.

Gender-affirming hormone therapy preserves skeletal maturation in young mice via the gut microbiome

Gender-affirming hormone therapy (GAHT) is often prescribed to transgender (TG) adolescents to alleviate gender dysphoria, but the effect of GAHT on the growing skeleton is unclear. We found GAHT to improve trabecular bone structure via increased bone formation in young male mice and not to affect trabecular structure in female mice. GAHT modified gut microbiome composition in both male and female mice. However, fecal microbiota transfers (FMTs) revealed that GAHT-shaped gut microbiome was a communicable regulator of bone structure and turnover in male, but not in female mice. Mediation analysis identified 2 species of Bacteroides as significant contributors to the skeletal effects of GAHT in male mice, with Bacteroides supplementation phenocopying the effects of GAHT on bone. Bacteroides have the capacity to expand Treg populations in the gut. Accordingly, GAHT expanded intestinal Tregs and stimulated their migration to the bone marrow (BM) in male but not in female mice. Attesting to the functional relevance of Tregs, pharmacological blockade of Treg expansion prevented GAHT-induced bone anabolism. In summary, in male mice GAHT stimulated bone formation and improved trabecular structure by promoting Treg expansion via a microbiome-mediated effect, while in female mice, GAHT neither improved nor impaired trabecular structure.

Serum Hormone Concentrations in Transgender Youth Receiving Estradiol

OBJECTIVE

This study aimed to evaluate the serum estradiol levels in gender-diverse youth to compare the efficacy of different estradiol routes in achieving therapeutic blood levels and suppressing serum testosterone levels.

METHODS

This was a retrospective chart review of patients who initiated estradiol at an adolescent gender clinic between 2010 and 2019. Data on the route of estradiol administration and antiandrogen use (spironolactone or gonadotropin-releasing hormone agonist) were collected, and laboratory data were analyzed. Scatterplots were used to visualize the relationship between the estradiol dose and testosterone and estradiol laboratory values.

RESULTS

A total of 118 patients were included, with a mean (standard deviation [SD]) age of 17.2 (1.6) years. The most common route of estradiol administration was oral only (62.7%), followed by transdermal only (23.7%), multiple routes excluding subcutaneous (8.5%), and any subcutaneous (5.1%). Notable variability was observed in the serum estradiol levels, with means (SDs) of 131.9 (120.4) pg/mL for those on oral estrogen 6 to 8 mg per day, 62.6 (40.3) pg/mL for those on transdermal estrogen 0.1 to 0.15 mg every 24 hours, and 53.6 (42.4) pg/mL for those on subcutaneous estradiol. In patients who received spironolactone, transdermal estradiol was associated with lower testosterone levels than estradiol administered orally or subcutaneously.

CONCLUSION

Oral, transdermal, and subcutaneous administrations of estrogen all lead to increased serum estradiol levels and are effective for use in gender-affirming care for youth. Patients on transdermal estrogen tended to have lower serum estradiol levels but also had more suppression of serum testosterone levels.

Estradiol increases cortical and trabecular bone accrual and bone strength in an adolescent male-to-female mouse model of gender-affirming hormone therapy

The effects of gender-affirming hormone therapy on the skeletal integrity and fracture risk in transitioning adolescent trans girls are unknown. To address this knowledge gap, we developed a mouse model to simulate male-to-female transition in human adolescents in whom puberty is first arrested by using gonadotrophin-releasing hormone analogs with subsequent estradiol treatment. Puberty was suppressed by orchidectomy in male mice at 5 weeks of age. At 3 weeks post-surgery, male-to-female mice were treated with a high dose of estradiol (~0.85 mg) by intraperitoneal silastic implantation for 12 weeks. Controls included intact and orchidectomized males at 3 weeks post-surgery, vehicle-treated intact males, intact females and orchidectomized males at 12 weeks post-treatment. Compared to male controls, orchidectomized males exhibited decreased peak bone mass accrual and a decreased maximal force the bone could withstand prior to fracture. Estradiol treatment in orchidectomized male-to-female mice compared to mice in all control groups was associated with an increased cortical thickness in the mid-diaphysis, while the periosteal circumference increased to a level that was intermediate between intact male and female controls, resulting in increased maximal force and stiffness. In trabecular bone, estradiol treatment increased newly formed trabeculae arising from the growth plate as well as mineralizing surface/bone surface and bone formation rate, consistent with the anabolic action of estradiol on osteoblast proliferation. These data support the concept that skeletal integrity can be preserved and that long-term fractures may be prevented in trans girls treated with GnRHa and a sufficiently high dose of GAHT. Further study is needed to identify an optimal dose of estradiol that protects the bone without adverse side effects.

Interest In and Prior Receipt of Counseling on Fertility Preservation in Transgender Patients Presenting for Gender-affirming Orchiectomy

OBJECTIVE

To describe the characteristics of patients presenting for gender-affirming bilateral simple orchiectomy including interest in and prior education on reproductive options prior to gonad removal.

METHODS

A retrospective chart review evaluated patients seeking gender-affirming bilateral orchiectomy. Data collected included age, family history, history of fertility preservation education prior to gender-affirming hormone therapy initiation, prior fertility preservation, interest in fertility preservation, and postorchiectomy surgical pathology results where applicable.

RESULTS

The cohort included 78 patients. 22% (n = 17) indicated reproductive options were not discussed prior to surgical consultation. 85% (n = 66) were not interested in fertility preservation. Reasons included not having an interest in biological children (74%), not wanting to delay transition (47%), and cost (36%). Patients who were married or in long-term relationships had a higher interest in fertility preservation compared to patients who were not in long-term relationships. 40% of patients with pathology data available had at least some level of spermatogenesis present in their testicular tissue.

CONCLUSION

Fertility preservation counseling prior to surgical referral was lower than expected. This lack of counseling could result in patients not wanting to sperm bank prior to orchiectomy as it could delay their surgical care. Increased adherence to the WPATH guidelines may improve fertility preservation interest. Our data shows a low utilization and interest in sperm preservation for transwomen and nonbinary patients seeking bilateral simple orchiectomy at our institution. Improving counseling regarding fertility preservation options earlier in transition could improve utilization of sperm cryopreservation.

Position paper of the Italian association of medical oncology on health disparities among transgender and gender-diverse people: the Assisi recommendations

Transgender and gender-diverse individuals experience substantial health disparities across the cancer care continuum. Despite well recognized unique healthcare needs, there are barriers in accessing cancer prevention and treatment services, influenced by disadvantages in key social-economic determinants of health which result in worse clinical outcomes, as compared to the general population. The Italian Association of Medical Oncology (AIOM) acknowledges the critical relevance of this issue. The "Assisi Recommendations" here summarize the outcomes of the "AIOM Oncology Ethics Day" dedicated to gender differences in oncology and cancer care of transgender and gender-diverse people. The recommendations generated during a 2-day multidisciplinary discussion address the various aspects of cancer care experience of transgender and gender-diverse people. The promotion of research in this field, through the generation of new evidence and the collection of prospective data, has been identified as a priority action to mitigate these disparities. By acknowledging the challenges of cancer care in transgender and gender-diverse people and recognizing the need for dedicated policy and clinical recommendations, AIOM demonstrates its commitment to improving the health and well-being of all patients with cancer, regardless of their gender identity or any other personal or social circumstances, as part of health-for-all societal vision.

Cancer Screening for Transgender Individuals: Guidelines, Best Practices, and a Proposed Care Model

Few transgender-specific cancer screening recommendations exist. This review aims to cover current guidelines and practice patterns of cancer screening in transgender patients and, where evidence-based data are lacking, to draw from cisgender screening guidelines to suggest best practices for transgender patients based on anatomic inventory. Sufficient evidence does not exist to determine the long-term effects of gender-affirming hormone therapy on cancer risk. In the future, cancer screening and prevention should be focused on anatomic inventory and high-risk behaviors.

In vitro fertilization outcomes in a mouse model of gender-affirming hormone therapy in transmasculine youth

OBJECTIVE

To investigate in vitro fertilization (IVF) outcomes in an adolescent transmasculine mouse model mimicking gender-affirming hormone therapy in prepubertal youth, both on testosterone (T) and after T washout.

DESIGN

Experimental laboratory study using a validated mouse model.

SETTING

University-based basic science research laboratory.

ANIMAL(S)

A total of 80 prepubertal 26-day-old C57BL/6N female mice were used in this study.

INTERVENTION(S)

Animals (n = 10/group) were implanted subcutaneously with gonadotropin-releasing hormone agonist at 3.6 mg or received sham surgery. After 21 days, they were implanted with silastic tubing containing either T 10 mg or placebo for 6 weeks. After 6 weeks, a group of animals were superovulated for immediate IVF, and another group had the implant removed and went through superovulation for IVF after 2 weeks (washout IVF). The total number of oocytes yielded, oocyte maturity rate, fertilization rate, and numbers of 2-cell embryos, 4-8-cell embryos, morula, blastocysts, and hatching blastocysts were recorded.

RESULT(S)

Testosterone treatment negatively impacted IVF outcomes in animals stimulated when receiving T, but not after T washout. Pretreatment with gonadotropin-releasing hormone agonist did not affect IVF outcomes.

CONCLUSION(S)

Although current T had a negative impact on IVF outcomes compared with controls, animals were still able to produce viable oocytes for fertilization and develop into blastocysts. Future efforts to study the impact of long-term T exposure on oocyte quality, especially aneuploidy rates, pregnancy outcomes, and live birth rates, are necessary.

Gender-Affirming Surgery in Adolescents and Young Adults: A Review of Ethical and Surgical Considerations

BACKGROUND

The number of transgender adolescents seeking gender-affirming surgery (GAS) in increasing. Surgical care of the adolescent transgender patient is associated with several unique technical, legal, and ethical factors. The authors present a review of the current literature on gender-affirming surgery for individuals under the age of legal majority and propose directions for future research.

METHODS

A scoping review of recent literature was performed to assess evidence on gender-affirming surgery in individuals under the age of legal majority. Articles were included that examined either ethical or technical factors unique to pediatric GAS. Study characteristics and conclusions were analyzed in conjunction with expert opinion.

RESULTS

Twelve articles were identified that met inclusion criteria. Ten of these articles discussed ethical challenges in adolescent GAS, seven discussed legal challenges, and five discussed technical challenges. Ethical discussions focused on the principles of beneficence, nonmaleficence, and autonomy. Legal discussions centered on informed consent and insurance coverage. Technical discussions focused on the effects of puberty blockade on natal tissue.

CONCLUSIONS

Surgical care of the adolescent transgender patient involves important ethical, legal, and technical considerations that must be addressed by the clinical team. As the population of individuals seeking GAS after puberty blockade increases, future research is needed describing functional and psychosocial outcomes in these individuals.

Breast Cancer Screening Recommendations for Transgender and Gender Diverse Patients: A Knowledge and Familiarity Assessment of Primary Care Practitioners

Breast cancer screening recommendations for transgender and gender diverse (TGD) patients have only been recently developed and many primary care practitioners (PCPs) are unaware of these specific recommendations. The aim of this study is to assess the level of familiarity and knowledge PCPs have with breast cancer screening recommendations for TGD patients. An anonymous survey was distributed to primary care physicians, primary care advanced practice practitioners, and internal medicine and family medicine residents at three academic medical systems in the United States (Mayo Clinic, University of Michigan, University of Texas - Medical Branch). Survey questions assessed the familiarity and knowledge base of TGD breast cancer screening recommendations, training and experience with TGD patients, and basic demographics of the practitioners. Of the 95 survey respondents, only 35% of respondents were aware that breast cancer screening recommendations for TGD patients existed. PCPs who had increased transgender specific health care training and direct clinical exposure to TGD patients demonstrated significantly higher levels of screening recommendation awareness. Two-thirds of respondents received TGD specific medical education during training or medical career and those who had increased transgender specific medical education or direct clinical exposure to TGD patients demonstrated significantly higher levels of screening recommendation awareness. Awareness of breast cancer screening recommendations for TGD patients is low among PCPs and varied based on the practitioner's prior TGD education and experience. Up-to-date breast cancer screening recommendations for TGD patients should be readily available across multiple platforms, target key audiences, and integrated into transgender health educational curriculums to maximize awareness of these important recommendations.

Distinct mucosal and systemic immunological characteristics in transgender women potentially relating to HIV acquisition

Transgender women (TGW) are disproportionally affected by HIV infection, with a global estimated prevalence of 19.9%, often attributed to behavioral risk factors, with less known about biological factors. We evaluated potential biological risk factors for HIV acquisition in TGW at the sites of viral entry by assessing immune parameters of the neovaginal surface and gut mucosa. The neovagina in TGW, compared with the vagina in cisgender women (CW), shows distinct cell composition and may pose a more inflammatory environment, evidenced by increased CD4+ T cell activation and higher levels of soluble markers of inflammation (C-reactive protein, soluble CD30). Increased inflammation may be driven by microbiome composition, as shown by a greater abundance of Prevotella and a higher Shannon Diversity Index. In addition, we have observed higher frequency of CD4+CCR5+ target cells and decreased DNA methylation of the CCR5 gene in the gut mucosa of TGW compared with CW and men who have sex with men, which was inversely correlated with testosterone levels. The rectal microbiome composition in TGW appears to favor a proinflammatory milieu as well as mucosal barrier disruption. Thus, it is possible that increased inflammation and higher frequencies of CCR5-expressing target cells at sites of mucosal viral entry may contribute to increased risk of HIV acquisition in TGW, with further validation in larger studies warranted.

Hypertension: sex-related differences in drug treatment, prevalence and blood pressure control in primary care

Antihypertensive treatment is equally beneficial for reducing cardiovascular risk in both men and women. Despite this, the drug treatment, prevalence and control of hypertension differ between men and women. Men and women respond differently, particularly with respect to the risk of adverse events, to many antihypertensive drugs. Certain antihypertensive drugs may also be especially beneficial in the setting of certain comorbidities - of both cardiovascular and extracardiac nature - which also differ between men and women. Furthermore, hypertension in pregnancy can pose a considerable therapeutic challenge for women and their physicians in primary care. In addition, data from population-based studies and from real-world data are inconsistent regarding whether men or women attain hypertension-related goals to a higher degree. In population-based studies, women with hypertension have higher rates of treatment and controlled blood pressure than men, whereas real-world, primary-care data instead show better blood pressure control in men. Men and women are also treated with different antihypertensive drugs: women use more thiazide diuretics and men use more angiotensin-enzyme inhibitors and calcium-channel blockers. This narrative review explores these sex-related differences with guidance from current literature. It also features original data from a large, Swedish primary-care register, which showed that blood pressure control was better in women than men until they reached their late sixties, after which the situation was reversed. This age-related decrease in blood pressure control in women was not, however, accompanied by a proportional increase in use of antihypertensive drugs and female sex was a significant predictor of less intensive antihypertensive treatment.

Management of transgender patients in critical care

As clinicians working in critical care, it is our duty to provide all of our patients with the high-quality care they deserve, regardless of their gender identity. The transgender community continues to suffer discrimination from the media, politicians and general public. As healthcare workers we often pride ourselves on our ability to safely care for all patients. However, there remains a distinct lack of understanding surrounding the care of critically ill transgender patients. This is likely in part because the specific care of transgender patients is not included in the Faculty of Intensive Care Medicine's, Royal College of Anaesthetists', Royal College of Physician's, or Royal College of Emergency Medicine's curriculum. There are several important considerations relevant for transgender patients in critical care including anatomical changes to the airway, alterations to respiratory and cardiovascular physiology and management of hormone therapy. Alongside this, there are simple but important social factors that exist, such as the use of patient pronouns and ensuring admittance to correctly gendered wards. In this review we will address the key points relevant to the care of transgender patients in critical care and provide suggestions on how education on the subject may be improved.

Gender-Affirming Surgery of the Mandible: Lower Jaw Feminization and Masculinization

For patients with gender dysphoria, gender-affirming surgery of the face has been shown to vastly improve quality of life. The mandible is one area of the face that has distinct feminine and masculine presentations. This article will review gender-affirming surgery of the lower jaw, both for feminization and masculinization. Techniques for bony contouring and soft tissue manipulation will be discussed.

Success in Accessing Fertility Preservation Appointments for Egg-Producing Transgender and Gender-Diverse Patients: A Mystery Caller Study

Purpose: This study aimed to evaluate access to fertility preservation appointments for egg-producing transgender and gender-diverse patients. Methods: Fertility clinics nationwide were identified through the 2018 National Assisted Reproductive Technology Surveillance System dataset of the Centers for Disease Control and Prevention. Using a mystery caller approach with a standardized, community-developed script, three researchers called 456 clinics between July and December 2020 identifying themselves as a transgender man seeking oocyte cryopreservation. Information was collected regarding access to fertility preservation for the caller. Univariate and multivariable logistic regression analysis were used to compare call outcomes by geographic region and clinic demographics. Results: Of 369 clinics included in the final analysis, 90.2% of clinics offered an initial appointment. A clinic that offered an appointment was four times more likely to be located on the West Coast (95% confidence interval [CI] 1.33-12.7; p = 0.014). Notably, endorsement of prior experience caring for transgender patients was most strongly associated with an appointment being offered (odds ratio = 7.31; 95% CI: 3.44-15.5; p < 0.001). Themes across some calls included a lack of knowledge about transgender identities and care models (e.g., requiring a letter of support) leading to additional steps (e.g., having to explain anatomy or being transferred to another staff member) before accessing an appointment. Conclusion: The majority of clinics offered an initial appointment to a caller identifying as a transgender man seeking oocyte cryopreservation, suggesting access to an initial appointment is not a major barrier.

No Thromboembolic Complications After Facial Feminization Surgery in Transgender Patients Utilizing Estrogen Therapy: A Retrospective Cohort Study

Purpose

Estrogen therapy is associated with an increased risk of venous thromboembolism (VTE). A large proportion of transfeminine patients use estrogen therapy before undergoing gender-affirming surgery. Many surgeons implement the discontinuation of hormone therapy before surgery. This study sought to evaluate the perioperative risk of VTE in transfeminine patients undergoing the procedure of facial feminization.

Methods

Retrospective chart reviews were performed of all patients who underwent facial feminization by a single surgeon at an urban academic institution from 2014 to 2020. Patient characteristics including comorbidities, Caprini score, VTE chemoprophylaxis, and perioperative hormone therapy management were reviewed. The incidences of VTE during perioperative hospital stay and within 1 week and 6 months after the surgical procedure were examined.

Results

There were 296 facial feminization procedures performed on 282 distinct patients who met criteria for inclusion in the study. Hormone therapy was prescribed to 83.6% of patients, 69.5% of whom reported that they held these medications before the procedure. Of those holding, 84.1% of patients reported they discontinued these medications between 2 and 4 weeks. No patients received VTE chemoprophylaxis. There were 0 VTE incidents during the patients' perioperative period up to 6 months postprocedure.

Conclusion

Our findings support that transfeminine patients who use estrogen hormone therapy are at a minimal risk to experience VTE when undergoing facial feminization procedures. Future directions include evaluating the psychologic effect of discontinuing hormone therapy to help guide perioperative decision making.

Sex Differences in Athletic Performance: Perspectives on Transgender Athletes

Sex hormone concentrations, particularly testosterone, are primary determinants of sex-based differences in athletic and sports performance, and this relationship may inform fair competition and participation for athletes. This article describes the sex-based dichotomy in testosterone and the implications for sex-based differences in individual sports performance, including factors that relate to athletic performance for transgender individuals, and areas of future investigation.

[Care pathways for young transgender people]

Gender incongruence corresponds to the mismatch between gender identity and gender/sex assigned at birth gender/sex assigned at birth. It can be accompanied by psychological distress. In line with the literature, an increase in consultations for gender incongruence has been observed, especially among young people. Multidisciplinary care should be offered to this population; here we provide an example of healthcare proposed at the university hospital of Nancy.

Efficacy of Video-based Education in Improving Understanding of Pediatric Fertility Preservation

Eighty percent of children diagnosed with cancer in childhood survive into adulthood. Fertility preservation (FP) is an important consideration, and procedures are available to reduce the risk of infertility following gonadotoxic therapies. Discussing FP options eases decision-making and minimizes regret; however, poor comprehension of these topics remains a challenge. This study evaluates if video-based educational tools increase understanding of FP options among pediatric patients and families. Videos were first tested among participants not at risk of infertility to ensure objective utility and optimize quality. In part 1, parents of pediatric surgical patients were randomized to view 2 publicly available educational videos on FP in differing orders. Each group completed pre-surveys and post-surveys assessing the comprehension and perception of video quality. In part 2, the parent and patient participants completed a comprehension assessment before and after viewing our institution-specific educational video, designed based on participant feedback from part 1. Part 1 results demonstrated a significant increase in participant knowledge and perceived understanding after viewing the videos ( P <0.001), regardless of order. In part 2, the post-test comprehension scores were significantly improved for all participants and all subgroups, P <0.01. Results suggest that video-based educational tools may help to reduce barriers to FP in pediatric oncology.

Children and adolescents in the Amsterdam Cohort of Gender Dysphoria: trends in diagnostic- and treatment trajectories during the first 20 years of the Dutch Protocol

BACKGROUND

Twenty years ago, the Dutch Protocol-consisting of a gonadotropin-releasing hormone agonist (GnRHa) to halt puberty and subsequent gender-affirming hormones (GAHs)-was implemented to treat adolescents with gender dysphoria.

AIM

To study trends in trajectories in children and adolescents who were referred for evaluation of gender dysphoria and/or treated following the Dutch Protocol.

METHODS

The current study is based on a retrospective cohort of 1766 children and adolescents in the Amsterdam Cohort of Gender Dysphoria.

OUTCOMES

Outcomes included trends in number of intakes, ratio of assigned sex at birth, age at intake, age at start of GnRHa and GAH, puberty stage at start of GnRHa, proportions of adolescents starting and stopping GnRHa, reasons for refraining from GnRHa, and proportions of people undergoing gender-affirming surgery.

RESULTS

A steep increase in referrals was observed over the years. A change in the AMAB:AFAB ratio (assigned male at birth to assigned female at birth) was seen over time, tipping the balance toward AFAB. Age at intake and at start of GnRHa has increased over time. Of possibly eligible adolescents who had their first visit before age 10 years, nearly half started GnRHa vs around two-thirds who had their first visit at or after age 10 years. The proportion starting GnRHa rose only for those first visiting before age 10. Puberty stage at start of GnRHa fluctuated over time. Absence of gender dysphoria diagnosis was the main reason for not starting GnRHa. Very few stopped GnRHa (1.4%), mostly because of remission of gender dysphoria. Age at start of GAH has increased mainly in the most recent years. When a change in law was made in July 2014 no longer requiring gonadectomy to change legal sex, percentages of people undergoing gonadectomy decreased in AMAB and AFAB.

CLINICAL IMPLICATIONS

A substantial number of adolescents did not start medical treatment. In the ones who did, risk for retransitioning was very low, providing ongoing support for medical interventions in comprehensively assessed gender diverse adolescents.

STRENGTHS AND LIMITATIONS

Important topics on transgender health care for children and adolescents were studied in a large cohort over an unprecedented time span, limited by the retrospective design.

CONCLUSION

Trajectories in diagnostic evaluation and medical treatment in children and adolescents referred for gender dysphoria are diverse. Initiating medical treatment and need for surgical procedures depends on not only personal characteristics but societal and legal factors as well.

Developmental Pathway Choices of Young People Presenting to a Gender Service with Gender Distress: A Prospective Follow-Up Study

This prospective case-cohort study examines the developmental pathway choices of 79 young people (13.25-23.75 years old; 33 biological males and 46 biological females) referred to a tertiary care hospital's Department of Psychological Medicine (December 2013-November 2018, at ages 8.42-15.92 years) for diagnostic assessment for gender dysphoria (GD) and for potential gender-affirming medical interventions. All of the young people had attended a screening medical assessment (including puberty staging) by paediatricians. The Psychological Medicine assessment (individual and family) yielded a formal DSM-5 diagnosis of GD in 66 of the young people. Of the 13 not meeting DSM-5 criteria, two obtained a GD diagnosis at a later time. This yielded 68 young people (68/79; 86.1%) with formal diagnoses of GD who were potentially eligible for gender-affirming medical interventions and 11 young people (11/79; 13.9%) who were not. Follow-up took place between November 2022 and January 2023. Within the GD subgroup (n = 68) (with two lost to follow-up), six had desisted (desistance rate of 9.1%; 6/66), and 60 had persisted on a GD (transgender) pathway (persistence rate of 90.9%; 60/66). Within the cohort as a whole (with two lost to follow-up), the overall persistence rate was 77.9% (60/77), and overall desistance rate for gender-related distress was 22.1% (17/77). Ongoing mental health concerns were reported by 44/50 (88.0%), and educational/occupational outcomes varied widely. The study highlights the importance of careful screening, comprehensive biopsychosocial (including family) assessment, and holistic therapeutic support. Even in highly screened samples of children and adolescents seeking a GD diagnosis and gender-affirming medical care, outcome pathways follow a diverse range of possibilities.

Updates in Transgender Breast Imaging

Transgender patients are seen in breast imaging centers for routine screening mammography and diagnostic imaging of the symptomatic breast. This comprehensive review of transgender breast imaging aims to update the radiologist on appropriate terminology, breast cancer risk in different patient populations, screening guidelines, and diagnostic scenarios. The chapter concludes with practical tips on how to optimize the patient experience.

The Dutch Protocol for Juvenile Transsexuals: Origins and Evidence

It has been a quarter of a century since Dutch clinicians proposed puberty suppression as an intervention for "juvenile transsexuals," which became the international standard for treating gender dysphoria. This paper reviews the history of this intervention and scrutinizes the evidence adduced to support it. The intervention was justified by claims that it was reversible and that it was a tool for diagnosis, but these claims are increasingly implausible. The main evidence for the Dutch protocol came from a longitudinal study of 70 adolescents who had been subjected to puberty suppression followed by cross-sex hormones and surgery. Their outcomes shortly after surgery appeared positive, except for the one patient who died, but these findings rested on a small number of observations and incommensurable measures of gender dysphoria. A replication study conducted in Britain found no improvement. While some effects of puberty suppression have been carefully studied, such as on bone density, others have been ignored, like on sexual functioning.

Effects of Hormones on Breast Development and Breast Cancer Risk in Transgender Women

Transgender women experience gender dysphoria due to a gender assignment at birth that is incongruent with their gender identity. Transgender people undergo different surgical procedures and receive sex steroids hormones to reduce psychological distress and to induce and maintain desired physical changes. These persons on feminizing hormones represent a unique population to study the hormonal effects on breast development, to evaluate the risk of breast cancer and perhaps to better understand the precise role played by different hormonal components. In MTF (male to female) patients, hormonal treatment usually consists of antiandrogens and estrogens. Exogenous hormones induce breast development with the formation of ducts and lobules and an increase in the deposition of fat. A search of the existing literature dedicated to hormone regimens for MTF patients, their impact on breast tissue (incidence and type of breast lesions) and breast cancer risk provided the available information for this review. The evaluation of breast cancer risk is currently complicated by the heterogeneity of administered treatments and a lack of long-term follow-up in the great majority of studies. Large studies with longer follow-up are required to better evaluate the breast cancer risk and to understand the precise mechanisms on breast development of each exogenous hormone.

[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.

Serum oestradiol levels and risk of adverse cardiovascular events associated with gender-affirming oestrogen therapy: a protocol for a systematic review and meta-analysis

INTRODUCTION

The use of gender-affirming oestrogen therapy (GAOT) is an integral part of the gender-affirming transition process for transgender women (assigned male at birth who identify as women) and gender-diverse individuals. However, its use may present significant cardiovascular implications, which may be influenced by systemic oestradiol levels. Therefore, we aim to establish the association between serum oestradiol levels and incidence of adverse cardiovascular events in individuals using GAOT.

METHODS AND ANALYSIS

We will conduct a systematic review addressing the association between serum oestradiol levels and risk of adverse cardiovascular events in individuals using GAOT. Our primary outcome is the incidence of adverse cardiovascular events, our secondary outcome is the incidence of cardiovascular-related mortality and our tertiary outcome is cardiovascular-related risk factors. Electronic databases (Cochrane Central Register of Controlled Trials, Embase, MEDLINE and Web of Science) will be searched from inception until September 2022. Two investigators will independently complete screening to determine appropriateness of inclusion. Extracted data will include information on serum sex hormone levels (oestradiol and testosterone), participants, GAOT (route of administration, formulations, dosages and duration of exposure), incidence of cardiovascular outcomes, study quality and risk of bias. Inter-reviewer reliability will be calculated at both phases. Data will be presented both descriptively and meta-analysed using a random effects model, if appropriate. Heterogeneity will be explored and meta-regressed if noted.

ETHICS AND DISSEMINATION

Ethics approval is not needed. We will disseminate findings through international conferences, distributions to transgender and gender-diverse support organisations, decision-makers and key stakeholders. The final systematic review will be published in a peer-reviewed journal.

Multicenter Analysis of Cardiometabolic-related Diagnoses in Transgender and Gender-Diverse Youth: A PEDSnet Study

CONTEXT

Studies on cardiometabolic health in transgender and gender-diverse youth (TGDY) are limited to small cohorts.

OBJECTIVE

This work aimed to determine the odds of cardiometabolic-related diagnoses in TGDY compared to matched controls in a cross-sectional analysis, using a large, multisite database (PEDSnet).

METHODS

Electronic health record data (2009-2019) were used to determine odds of cardiometabolic-related outcomes based on diagnosis, anthropometric, and laboratory data using logistic regression among TGDY youth vs controls. The association of gender-affirming hormone therapy (GAHT) with these outcomes was examined separately among TGDY. TGDY (n = 4172) were extracted from 6 PEDSnet sites and propensity-score matched on 8 variables to controls (n = 16 648). Main outcomes measures included odds of having cardiometabolic-related diagnoses among TGDY compared to matched controls, and among TGDY prescribed GAHT compared to those not prescribed GAHT.

RESULTS

In adjusted analyses, TGDY had higher odds of overweight/obesity (1.2; 95% CI, 1.1-1.3) than controls. TGDY with a testosterone prescription alone or in combination with a gonadotropin-releasing hormone agonist (GnRHa) had higher odds of dyslipidemia (1.7; 95% CI, 1.3-2.3 and 3.7; 95% CI, 2.1-6.7, respectively) and liver dysfunction (1.5; 95% CI, 1.1-1.9 and 2.5; 95% CI, 1.4-4.3) than TGDY not prescribed GAHT. TGDY with a testosterone prescription alone had higher odds of overweight/obesity (1.8; 95% CI, 1.5-2.1) and hypertension (1.6 95% CI, 1.2-2.2) than those not prescribed testosterone. Estradiol and GnRHa alone were not associated with greater odds of cardiometabolic-related diagnoses.

CONCLUSION

TGDY have increased odds of overweight/obesity compared to matched controls. Screening and tailored weight management, sensitive to the needs of TGDY, are needed.

Standards of Care for the Health of Transgender and Gender Diverse People, Version 8

Background: Transgender healthcare is a rapidly evolving interdisciplinary field. In the last decade, there has been an unprecedented increase in the number and visibility of transgender and gender diverse (TGD) people seeking support and gender-affirming medical treatment in parallel with a significant rise in the scientific literature in this area. The World Professional Association for Transgender Health (WPATH) is an international, multidisciplinary, professional association whose mission is to promote evidence-based care, education, research, public policy, and respect in transgender health. One of the main functions of WPATH is to promote the highest standards of health care for TGD people through the Standards of Care (SOC). The SOC was initially developed in 1979 and the last version (SOC-7) was published in 2012. In view of the increasing scientific evidence, WPATH commissioned a new version of the Standards of Care, the SOC-8. Aim: The overall goal of SOC-8 is to provide health care professionals (HCPs) with clinical guidance to assist TGD people in accessing safe and effective pathways to achieving lasting personal comfort with their gendered selves with the aim of optimizing their overall physical health, psychological well-being, and self-fulfillment. Methods: The SOC-8 is based on the best available science and expert professional consensus in transgender health. International professionals and stakeholders were selected to serve on the SOC-8 committee. Recommendation statements were developed based on data derived from independent systematic literature reviews, where available, background reviews and expert opinions. Grading of recommendations was based on the available evidence supporting interventions, a discussion of risks and harms, as well as the feasibility and acceptability within different contexts and country settings. Results: A total of 18 chapters were developed as part of the SOC-8. They contain recommendations for health care professionals who provide care and treatment for TGD people. Each of the recommendations is followed by explanatory text with relevant references. General areas related to transgender health are covered in the chapters Terminology, Global Applicability, Population Estimates, and Education. The chapters developed for the diverse population of TGD people include Assessment of Adults, Adolescents, Children, Nonbinary, Eunuchs, and Intersex Individuals, and people living in Institutional Environments. Finally, the chapters related to gender-affirming treatment are Hormone Therapy, Surgery and Postoperative Care, Voice and Communication, Primary Care, Reproductive Health, Sexual Health, and Mental Health. Conclusions: The SOC-8 guidelines are intended to be flexible to meet the diverse health care needs of TGD people globally. While adaptable, they offer standards for promoting optimal health care and guidance for the treatment of people experiencing gender incongruence. As in all previous versions of the SOC, the criteria set forth in this document for gender-affirming medical interventions are clinical guidelines; individual health care professionals and programs may modify these in consultation with the TGD person.

Fertility preservation in transgender men and the need for uniform, comprehensive counseling

Objective

To review the literature to assess best practices for counseling transgender men who desire gender-affirming surgery on fertility preservation options.

Design

A scoping review of articles published through July 2021.

Setting

None.

Patient(s)

Articles published in Cochrane, Web of Science, PubMed, Science Direct, SCOPUS, and Psychinfo.

Intervention(s)

None.

Main Outcome Measure(s)

Papers discussing transgender men, fertility preservation (FP), and FP counseling.

Result(s)

The primary search yielded 1,067 publications. After assessing eligibility and evaluating with a quality assessment tool, 25 articles remained, including 8 reviews, 5 surveys, 4 consensus studies, 3 retrospective studies, 3 committee opinions, and 2 guidelines. Publications highlighted the importance of including the following topics during counseling: (1) FP and family building options; (2) FP outcomes; (3) effects of testosterone therapy on fertility; (4) contraception counseling; (5) attitudes toward family building; (6) consequences of transgender parenting; and (7) barriers to success.

Conclusion(s)

Currently, there is a lack of standardization for comprehensive counseling about FP for transgender men. Standardized approaches can facilitate conversation between physicians and transgender men and ensure patients are making informed decisions regarding pelvic surgery and future family building plans.

Hormonal therapies and venous thrombosis: Considerations for prevention and management

Background

Venous thromboses are well‐established complications of hormonal therapy. Thrombosis risk is seen with both hormonal contraceptive agents and with hormone replacement therapy for menopause and gender transition. Over the past several decades, large epidemiological studies have helped better define these risks.

Objectives

To review and discuss the differences in thrombosis risk of the many of hormonal preparations available as well as their interaction with patient‐specific factors.

Methods

We conducted a narrative review of the available literature regarding venous thrombosis and hormonal therapies including for contraception, menopausal symptoms, and gender transition.

Results

Thrombosis risk with estrogen‐containing compounds increases with increasing systemic dose of estrogen. While progesterone‐only–containing products are not associated with thrombosis, when paired with estrogen in combined oral contraceptives, the formulation of progesterone does impact the risk. These components, along with patient‐specific factors, may influence the choice of hormonal preparation. For patients who develop thrombosis on hormonal treatment, anticoagulation is protective against future thrombosis. Duration of anticoagulation is dependent on ongoing and future hormone therapy choice. Finally, the optimal management of hormone therapy for individuals diagnosed with prothrombotic illnesses such as COVID‐19 remains unclear.

Conclusions

When contemplating hormonal contraception or hormone replacement therapy, clinicians must consider a variety of factors including hormone type, dose, route, personal and family history of thrombosis, and other prothrombotic risk factors to make informed, personalized decisions regarding the risk of venous thrombosis.

Puberty Suppression in Transgender and Gender-Diverse Adolescents: Timely Care for Optimal Outcomes

In this perspective, we argue that pubertal suppression with gonadotropin-releasing hormone analogues is a safe reversible intervention that should be made available to transgender and gender-diverse youth starting at early puberty. Recent data suggest puberty suppression is generally initiated among individuals once puberty has significantly progressed, thus reducing the effectiveness of the intervention. Delays and barriers to such care may systematically introduce permanent avoidable disadvantages for this vulnerable and marginalized group.

Use of Hormones Among Trans Women in the West Coast of Peninsular Malaysia: A Mixed Methods Study

Purpose:

There are no national data on hormone use by trans women in Malaysia. The objective of this study was to determine hormone use and the associated factors by trans women in Malaysia.

Methods:

This mixed method (quantitative and qualitative) study (JPEC 03-18-0021) was conducted using a self-administered questionnaire among trans women who used hormones and recruited using snow ball sampling method. All participants had undergone a blood test in an assigned laboratory. Besides total testosterone and total estradiol blood levels, renal and liver function tests and lipid profile were done.

Results:

A total of 111 out of the 141 respondents who participated were taking hormones. The main reason for not taking hormones was the concern for side effects. The main source of information concerning hormones was friends, and most procured the hormones from pharmacy without prescription and without first undergoing a physical or blood examination. All were on estrogens and only about half were on progesterone. The common mode of intake was oral and by injection. Most were on <4 mg of estrogens and did not report any major complication. Most rated the hormone affordability and satisfaction as good. Most had inadequate testosterone and estradiol blood levels. Except for total cholesterol and low-density lipoproteins, all other blood tests were normal. Correlation between serum testosterone and estradiol (R² 0.012. B−9.273 (95% confidence interval −16.44 to −2.11). p=0.012) was statistically significant.

Conclusion:

The prevalence of hormone use was high, mostly nonprescription use and with no medical supervision.
