Gender-affirming hormonal therapy for transgender and gender-diverse people-A narrative review

Development of a large Danish single-centre retro- and prospective transgender cohort using a web-based platform: a study protocol of a transgender cohort study

INTRODUCTION

Referrals for gender-affirming healthcare services have surged in recent decades, presumably driven by increased visibility, acceptance and reduced barriers to care. Despite these advances, transgender and gender-diverse individuals continue to face significant mental health challenges, including elevated rates of anxiety, depression as well as high prevalence of autistic traits. Gender-affirming hormonal treatment (GAHT) has been suggested to improve mental health and quality of life (QoL) among transgender individuals; however, the short- and long-term treatment effects of GAHT are not yet fully understood. Therefore, this study aims to establish a comprehensive cohort of transgender individuals at the Centre for Gender Identity (CGI), Aalborg University Hospital, Denmark, to enhance understanding and treatment outcomes.

METHODS AND ANALYSIS

The Transgender Cohort (TraCK) will recruit participants from February 14, 2024, with recruitment occurring continuously alongside yearly follow-up. This single-centre cohort study will include both retrospective and prospective data collection. Transgender individuals referred to CGI will be invited to participate in the study via the Danish digital mail system called e-Boks. Participants must provide informed consent and complete a baseline questionnaire. Data will be collected from self-reported questionnaires and medical records across multiple specialists. Self-reported questionnaires include WHO-Quality of Life BREF, Eating Disorders Examination Questionnaire, Autism Spectrum Quotient, Transgender Congruence Scale, and Gender Minority Stress and Resilience Measure. Medical records will provide information on demographics, mental health, physical health, and gender-affirming treatment details. Data will be managed using REDCap, ensuring compliance with GDPR and the National Data Protection Act.

ETHICS AND DISSEMINATION

While recognising the potential privacy risks associated with data collection, the study considers these outweighed by the benefits of advancing knowledge on gender diversity and the impacts of gender-affirming care. The North Jutland Region Ethics Committee reviewed the project, determining no formal approval was needed, but it was registered and approved (no. F2024-012) by the North Jutland Region. Findings will be disseminated through peer-reviewed journals, conferences, and accessible reports for participants.

REGISTRATION DETAILS

This study is registered with the North Jutland Region (no. F2024-012). Recruitment and data collection began on February 14, 2024, and will continue alongside yearly follow-up.

The intersection of the laboratory and transgender care

Transgender and gender diverse (TGD) individuals seeking gender affirming treatment are an increasing demographic in today's society; such treatments include hormonal and surgical interventions aimed at alleviating gender dysphoria and increasing quality of life. A number of diagnostic pathology tests are provided to medical professionals with sex specific reference intervals (RIs) for interpretation, due to sex specific physiological differences, organ size and hormone levels for example. These tests may be reported with RIs that are not appropriate, and interpretation for the medical professional can be challenging. From the laboratory perspective, there are limitations in Laboratory Information Management Systems (LIMS) and the ability of these databases to record both sex and gender identifiers, as well as the reporting of appropriate RIs. The use of RIs derived from the transgender population is complex, studies generally have a low sample size and include adults with long established hormonal treatments. The age of an individual undergoing gender affirming therapy has decreased, and the use of Gonadotrophin Releasing Hormone analogues adds complexity. In this review, we will discuss the current challenges and perspectives regarding the reporting of reference intervals in the TGD population, the derivation of personalized or transgender specific RIs and interpretation of specific diagnostic tests.

Incidence of cervical intraepithelial neoplasia and cervical cancer in transmasculine and gender diverse individuals using testosterone: a retrospective, single-centre cohort study

Background

The number of transmasculine and gender diverse (TMGD) individuals who retain their uterus or postpone surgery while using testosterone is increasing. However, the influence of exogenous testosterone on the risk of cervical cancer remains unclear. This study aims to assess the risk of cervical cancer and intraepithelial neoplasia in TMGD individuals undergoing testosterone treatment.

Methods

This retrospective, cohort study was conducted at the Amsterdam University Medical Centre in the Netherlands, included transmasculine and gender diverse (TMGD) individuals receiving testosterone at our clinic between February 17, 1972 and December 3, 2018. Data from medical records were linked to the national pathology database to acquire diagnoses related to cervical cancer or cervical intraepithelial neoplasia (CIN). Individuals assigned female at birth who received testosterone were included, excluding those last seen before 1991. Lesions ≥ CIN2 were classified as "high grade", considering their increased cancer progression risk. Based on observed and expected cases, age-adjusted standardised incidence ratios (SIR) were calculated to assess relative risk compared to cisgender women.

Findings

The cohort comprised 2095 TMGD individuals; 1200 participants underwent hysterectomy, and cervical biopsies obtained from seven patients. Median testosterone exposure time was 1.7 years (IQR 1.3-2.5). No cervical cancer cases were observed (0.30 (95% CI 0-1.4) expected). Five cases of ≥CIN2 (0.002%) were observed, versus 9.5 expected (SIR 0.53 (95% CI 0.19-1.17).

Interpretation

In this large cohort with several years of testosterone exposure we did not observe any cervical cancer, nor did we observe an increased risk of ≥CIN2. These findings should be interpreted with caution, as the relatively short median time of follow-up and lack of data on HPV infection prevalence and cervical screening may introduce bias. Longer follow-up studies incorporating this information are needed.

Funding

Inflammation as a Potential Mechanism Contributing to Sexual Functioning Following Initiation of Gender-Affirming Hormone Therapy

Purpose of Review

Many transgender and gender non-conforming (TGNC) people seek gender-affirming hormone therapy (GAHT). While GAHT is generally safe and increases well-being, it is essential to accurately understand potential unintended effects and risk factors to better inform and manage treatment. This narrative review covers recent literature documenting changes in sexual function following the initiation of GAHT and explores inflammation as a potential mediator of these changes.

Recent Findings

Generally, the initiation of GAHT is correlated with increased sexual desire in transgender men and decreased sexual desire in transgender women, with time-limited effects that return to levels approaching baseline after about a year; there are also changes in inflammation markers that parallel this timeline. Findings on other aspects of sexual function (e.g., orgasm, pain, and sexual quality of life) are more limited. As there is evidence from cisgender populations that inflammation acts as a mechanism by which hormones influence sexual function, we propose applying this model to TGNC people taking GAHT.

Summary

Sexual function may change in TGNC patients receiving GAHT, and those changes may be influenced by inflammation. However, these changes often return to baseline as TGNC patients' bodies adjust to a new hormonal equilibrium.

Adolescent gender dysphoria management: position paper from the Italian Academy of Pediatrics, the Italian Society of Pediatrics, the Italian Society for Pediatric Endocrinology and Diabetes, the Italian Society of Adolescent Medicine and the Italian Society of Child and Adolescent Neuropsychiatry

BACKGROUND

In response to the imperative need for standardized support for adolescent Gender Dysphoria (GD), the Italian Academy of Pediatrics, in collaboration with the Italian Society of Pediatrics, the Italian Society for Pediatric Endocrinology and Diabetes, Italian Society of Adolescent Medicine and Italian Society of Child and Adolescent Neuropsychiatry is drafting a position paper. The purpose of this paper is to convey the author's opinion on the topic, offering foundational information on potential aspects of gender-affirming care and emphasizing the care and protection of children and adolescents with GD.

MAIN BODY

Recognizing that adolescents may choose interventions based on their unique needs and goals and understanding that every individual within this group has a distinct trajectory, it is crucial to ensure that each one is welcomed and supported. The approach to managing individuals with GD is a multi-stage process involving a multidisciplinary team throughout all phases. Decisions regarding treatment should be reached collaboratively by healthcare professionals and the family, while considering the unique needs and circumstances of the individual and be guided by scientific evidence rather than biases or ideologies. Politicians and high court judges should address discrimination based on gender identity in legislation and support service development that aligns with the needs of young people. It is essential to establish accredited multidisciplinary centers equipped with the requisite skills and experience to effectively manage adolescents with GD, thereby ensuring the delivery of high-quality care.

CONCLUSION

Maintaining an evidence-based approach is essential to safeguard the well-being of transgender and gender diverse adolescents.

Affirming Care for Transgender and Gender-Diverse Youth

ABSTRACT

Nurses play a critical role in providing gender-affirming care for transgender and gender-diverse youth. With heightened debate about the clinical care for transgender and gender-diverse youth in the national and global spotlight, now more than ever before nurses must equip themselves with the knowledge and the evidence spanning more than 4 decades that support the clinical use of gender-affirming care for youth and young adults. By exploring gender development and gender-affirming care approaches through the lifespan perspective, this review provides an up-to-date discussion about best practices and clinical implications for providing equitable care for transgender and gender-diverse youth from birth to childhood and through adolescence developmental phases. A transgender and gender-diverse youth's future willingness to access health care is dependent on how positive their interactions are with their care team at this sensitive moment in their life. Nurses must not let political rhetoric impede their practice and ethical guidelines to provide competent, skilled, and unbiased care. Knowledgeable, informed, and empowered nurses can provide life-saving care to transgender and gender-diverse youth and their families.

Risk Assessment of Transgender People: Development of Rodent Models Mimicking Gender-Affirming Hormone Therapies and Identification of Sex-Dimorphic Liver Genes as Novel Biomarkers of Sex Transition

Transgender (TG) describes individuals whose gender identity differs from the social norms. TG people undergoing gender-affirming hormone therapy (HT) may be considered a sub-group of the population susceptible to environmental contaminants for their targets and modes of action. The aim of this study is to set appropriate HT doses and identify specific biomarkers to implement TG animal models. Four adult rats/group/sex were subcutaneously exposed to three doses of HT (plus control) selected starting from available data. The demasculinizing-feminizing models (dMF) were β-estradiol plus cyproterone acetate, at 0.09 + 0.33, 0.09 + 0.93 and 0.18 + 0.33 mg, respectively, five times/week. The defeminizing-masculinizing models (dFM) were testosterone (T) at 0.45, 0.95 and 2.05 mg, two times/week. Clitoral gain and sperm count, histopathological analysis of reproductive organs and liver, hormone serum levels and gene expression of sex-dimorphic CYP450 were evaluated. In the dMF model, the selected doses-leading to T serum levels at the range of the corresponding cisgender-induced strong general toxicity and cannot be used in long-term studies. In the dFM model, 0.45 mg of T represents the correct dose. In addition, the endpoints selected are considered suitable and reliable to implement the animal model. The sex-specific CYP expression is a suitable biomarker to set proper (de)masculinizing/(de)feminizing HT and to implement TG animal models.
