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

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.

The Effect of Gender-Affirming Hormones on Gender Dysphoria, Quality of Life, and Psychological Functioning in Transgender Individuals: A Systematic Review

Gender-affirming hormone therapy (GAHT) is an essential part of gender affirmation for many transgender (including people with binary and nonbinary identities) individuals and although controlled studies are unethical, there remains limited evidence on the impact of GAHT on gender dysphoria, quality of life (QoL), and psychological functioning. Some clinicians and policy makers use the lack of evidence to argue against providing gender-affirming care. The aim of this review is to systematically and critically assess the available literature on the influence of GAHT on improving gender- and body-related dysphoria, psychological well-being, and QoL. Using Preferred Reporting Items for Systematic Review and Meta-analysis guidelines, we searched Ovid MEDLINE®, Embase®, and Ovid PsycINFO® from inception to March 6, 2019 to assess the influence of GAHT on (1) gender dysphoria, (2) body uneasiness, (3) body satisfaction, (4) psychological well-being, (5) QoL, (6) interpersonal and global functioning, and (7) self-esteem. Our search strategy found no randomized controlled trials. Ten longitudinal cohort studies, 25 cross-sectional studies, and 3 articles reporting both cross-sectional and longitudinal data were identified. While results are mixed, the majority of studies demonstrate that GAHT reduces gender dysphoria, body dissatisfaction, and uneasiness, subsequently improving psychological well-being and QoL in transgender individuals. However, all current researches are of low to moderate quality comprising longitudinal cohort studies and cross-sectional studies, making it difficult to draw clear conclusions and do not reflect external social factors unaffected by GAHT, which significantly impact on dysphoria, well-being, and QoL.

Mental Health Outcomes Among Transgender Veterans and Active-Duty Service Members in the United States: A Systematic Review

Background

It has been shown that veterans and active-duty service members may experience worse mental health outcomes compared with civilians and nonveterans. In addition, transgender veterans and service members face unique challenges. We conducted a systematic review of articles presenting data on mental health outcomes in transgender veterans and active-duty service members. Outcomes examined in this review include symptoms of depression, anxiety, and posttraumatic stress disorder, suicidality, substance use, and military sexual trauma.

Observations

In the military, transgender individuals face stigma and discrimination. Transgender veterans and service members have worse mental health outcomes and higher odds of suicidality compared with their cisgender counterparts. Drug and alcohol use disorders are more prevalent among transgender veterans compared with cisgender veterans. Transgender veterans are also more likely to report military sexual trauma than cisgender veterans.

Conclusions

In the literature, evidence exists that transgender veterans and service members experience worse mental health outcomes than their cisgender counterparts. Additional research is required to measure the effect of gender-affirming care on health outcomes among transgender veterans and active-duty service members to better serve this population and provide optimal care.

The role of androgens in transgender medicine

Androgen therapy is the mainstay of treatment in female to male (FtM) transgender persons to increase testosterone levels, suppress oestrogens and treat gender dysphoria. Testosterone is widely used for male hypogonadism, but is comparatively under-investigated in FtM transgender persons. The aim of our study was to identify treatment and safety outcomes associated with testosterone use in transgender medicine. Androgens in FtM transgender persons are effective to lower voice frequency, increase facial hair-growth, and increase hematocrit and hemoglobin levels to adult male reference ranges. A 1.2-fold-3.7-fold higher rate of myocardial infarction has been reported retrospectively, compared to cisgender women. Blood pressure, glycaemic control and body mass index remained unchanged in FtM transgender persons. Androgens in FtM transgender persons have important cardio-metabolic implications. Randomised control trials, longer follow-up periods and studies involving older persons may further improve the management of FtM transgender persons.

The Impact of Gender-affirming Hormone Therapy on Anatomic Structures of the Brain Among Transgender Individuals

Despite the growing numbers of individuals who identify as transgender, this population continues to face worse mental health outcomes compared with the general population. Transgender individuals attempt suicide at a rate that is almost 9 times that of the general population. Few studies have reported on the positive effect of gender-affirming hormone therapy on mental health outcomes in transgender individuals. It is likely that this effect is due in part to the physiological responses that occur as a result of hormone therapy that mitigate incongruencies between one's gender identity and assigned sex. To our knowledge, only limited studies have shown a connection between gender-affirming hormone therapy, its effect on the brain's structure, and long-term effects that this may have on mental health outcomes. The authors propose that, in addition to the physiological responses that occur as a direct result of hormone therapy and the validation that results from receiving gender-affirming medical care, mental health outcomes in transgender individuals may also improve due to the role that hormone therapy plays in altering the brain's structure, possibly shaping the brain to become more like that of the gender with which an individual identifies. In this article, the authors review the current literature on the effects that gender-affirming hormone therapy has on mental health outcomes and anatomic structures of the brain in transgender individuals.

SIGIS-SIAMS-SIE position statement of gender affirming hormonal treatment in transgender and non-binary people

PURPOSE

Gender Incongruence (GI) is a marked and persistent incongruence between an individual's experienced and the assigned gender at birth. In the recent years, there has been a considerable evolution and change in attitude as regards to gender nonconforming people.

METHODS

According to the Italian Society of Gender, Identity and Health (SIGIS), the Italian Society of Andrology and Sexual Medicine (SIAMS) and the Italian Society of Endocrinology (SIE) rules, a team of experts on the topic has been nominated by a SIGIS-SIAMS-SIE Guideline Board on the basis of their recognized clinical and research expertise in the field, and coordinated by a senior author, has prepared this Position statement. Later on, the present manuscript has been submitted to the Journal of Endocrinological Investigation for the normal process of international peer reviewing after a first internal revision process made by the SIGIS-SIAMS-SIE Guideline Board.

RESULTS

In the present document by the SIGIS-SIAMS-SIE group, we propose experts opinions concerning the psychological functioning, gender affirming hormonal treatment, safety concerns, emerging issues in transgender healthcare (sexual health, fertility issues, elderly trans people), and an Italian law overview aimed to improve gender non-conforming people care.

CONCLUSION

In this Position statement, we propose experts opinions concerning the psychological functioning of transgender people, the gender-affirming hormonal treatment (full/partial masculinization in assigned female at birth trans people, full/partial feminization and de-masculinization in assigned male at birth trans people), the emerging issues in transgender health care aimed to improve patient care. We have also included an overview of Italian law about gender affirming surgery and registry rectification.

Providing Affirmative Care to Transgender and Gender Diverse Youth: Disparities, Interventions, and Outcomes

PURPOSE OF REVIEW

This paper reviews the evolving body of research on the mental health of transgender and gender diverse (TGD) youth. Minority stress experiences in families, schools, and the community impact the health and well-being of this population due to experiences of stigma, discrimination, and rejection. Poor healthcare access and outcomes may be compounded in youth with intersectional identities.

RECENT FINDINGS

There is increasing evidence that gender-affirming interventions improve mental health outcomes for TGD youth. TGD youth report worse mental health outcomes in invalidating school and family environments and improved outcomes in affirming climates. TGD youth experience significant healthcare disparities, and intersectional clinical approaches are needed to increase access to affirmative care. Providers can best support TGD youth by considering ways they can affirm these youth in their healthcare settings, and helping them access support in schools, family systems, and communities. Understanding the intersection of multiple minority identities can help providers address potential barriers to care to mitigate the health disparities seen in this population.

Hormone Therapy, Mental Health, and Quality of Life Among Transgender People: A Systematic Review

We sought to systematically review the effect of gender-affirming hormone therapy on psychological outcomes among transgender people. We searched PubMed, Embase, and PsycINFO through June 10, 2020 for studies evaluating quality of life (QOL), depression, anxiety, and death by suicide in the context of gender-affirming hormone therapy among transgender people of any age. We excluded case studies and studies reporting on less than 3 months of follow-up. We included 20 studies reported in 22 publications. Fifteen were trials or prospective cohorts, one was a retrospective cohort, and 4 were cross-sectional. Seven assessed QOL, 12 assessed depression, 8 assessed anxiety, and 1 assessed death by suicide. Three studies included trans-feminine people only; 7 included trans-masculine people only, and 10 included both. Three studies focused on adolescents. Hormone therapy was associated with increased QOL, decreased depression, and decreased anxiety. Associations were similar across gender identity and age. Certainty in this conclusion is limited by high risk of bias in study designs, small sample sizes, and confounding with other interventions. We could not draw any conclusions about death by suicide. Future studies should investigate the psychological benefits of hormone therapy among larger and more diverse groups of transgender people using study designs that more effectively isolate the effects of hormone treatment.

Testosterone therapy masculinizes speech and gender presentation in transgender men

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

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.

Testosterone, cortisol, and secretory immunoglobulin-A within a single day and across two sequential days among trans- and cis-gender men

BACKGROUND

Previous research on the association between testosterone (T) and immunity has produced conflicting results.

OBJECTIVES

We address two potential reasons for these empirical inconsistencies in the present research. First, the association between T and immunity may depend on which branch of the immune system is considered. Here, we examine secretory IgA (sIgA), a measure of mucosal immunity functionally related to respiratory infection risk. Second, the association between T and immunity may depend on a third regulatory variable. Therefore, we examine the interaction between T and cortisol (CORT) as well as their independent and combined effects on mucosal immunity. To do this, we explore intra-individual associations between sIgA, CORT, and T within a single day (i.e., morning vs. evening) and across 2 sequential mornings. We target two samples of men: (1) cisgender (i.e., born and identifying as men), and (2) transgender (i.e., born female but identifying as men) undergoing T therapy for gender realignment.

MATERIALS AND METHODS

One hundred and forty-eight adult men (transgender n = 29) provided saliva samples at three time points: (1) upon waking, (2) before sleep on the same day, and (3) upon waking the following day. Samples were assayed in duplicate for sIgA, T and CORT.

RESULTS

For cisgender men, sIgA, T, and CORT exhibited clear circadian rhythms and were significantly related within and between samples. For transgender men, evidence for circadian change was found for sIgA and CORT, but not T. Further, sIgA was associated with CORT, but not T.

DISCUSSION AND CONCLUSIONS

This study provides the first evidence that salivary T and sIgA concentrations are associated within a single day and across sequential days for cisgender men. Differences between cis- and transgender men suggest that this may only be true for T levels driven by endogenous production; however, future studies should employ a larger sample size.

Gender-Affirming Hormone Use in Transgender Individuals: Impact on Behavioral Health and Cognition

PURPOSE OF REVIEW

With increasing numbers of transgender and gender non-binary individuals presenting for care, knowing how to elucidate the mental health and cognitive outcomes of gender-affirming hormone therapy (GAHT) is necessary. This article reviews the present literature covering GAHT effects on mood, behavioral health, and cognition in these individuals and offers research priorities to address knowledge gaps.

RECENT FINDINGS

Although there are some conflicting data, GAHT overwhelmingly seems to have positive psychological effects in both adolescents and adults. Research tends to support that GAHT reduces symptoms of anxiety and depression, lowers perceived and social distress, and improves quality of life and self-esteem in both male-to-female and female-to-male transgender individuals. Clinically, prescribing GAHT can help with gender dysphoria-related mental distress. Thus, timely hormonal intervention represents a crucial tool for improving behavioral wellness in transgender individuals, though effects on cognitive processes fundamental for daily living are unknown. Future research should prioritize better understanding of how GAHT may affect executive functioning.

Masculine Voices Predict Well-Being in Female-to-Male Transgender Individuals

Voices convey important social information about an individual's identity, including gender. This is especially relevant to transgender individuals, who cite voice alteration as a primary goal of the gender alignment process. Although the voice is a primary target of testosterone therapy among female-to-male (FTM) trans people, little research has explored the effects of such changes on their psychological well-being. Here, we investigated how FTMs' vocal gender related to their well-being. A total of 77 FTMs (M _age = 25.45 years, SD = 6.77) provided voice samples and completed measures of their well-being and psychological health. An independent group of 32 naïve raters (M _age = 22.16 years, SD = 8.21) subsequently rated the voice samples for masculinity. We found that FTMs whose voices sounded more congruent with their experienced gender (i.e., sounded more masculine) reported greater well-being (better life satisfaction, quality of life, and self-esteem; lower levels of anxiety and depression) than FTMs with less gender congruent (i.e., more feminine) voices (β = .48). The convergence between outwardly perceived vocal gender and gender identity brought about through hormone replacement therapy may therefore support greater well-being for FTMs.
