Effects of hormones and hormone therapy on breast tissue in transgender patients: a concise review

PURPOSE

Hormone replacement therapy (HRT) has become a mainstay medical treatment option for management of gender dysphoria in transgender patients of both biologic sexes. Very little is known about the long-term effects of steroid hormone modulation on breast tissue in this population. Most of the data available on the effects of HRT on breast and reproductive tissues come from studies of postmenopausal cisgender women. Therapeutic regimens are often provider-dependent, and there, are no uniform guidelines in place for cancer surveillance in transgender patients. In this review, we present what forms of hormone therapy and hormone modulation are available to transgender patients, what is known about their effects on male and female breast tissue, and what other endogenous and exogenous factors contribute to the macroscopic and cellular changes observed.

METHODS

A search for the existing literature focusing on therapeutic regimens and the effects of HRT on breast tissue provided the most current information available for this review. Recent evidence-based reports (since the year 2000) and reviews were given priority over anecdotal evidence and expert opinions when conflicting information was encountered. Older resources were considered when primary sources were needed. Given the paucity of available articles on this subject, all resources were given careful consideration.

RESULTS

Information about the risks associated with HRT in the current literature and in this setting is limited and often conflicting, due to a scarcity of long-term studies tracking breast pathology among transgender men and women.

CONCLUSIONS

We conclude that the long-term effects of off-label pharmaceutical use for modulation of hormone levels and sexual characteristics in transgender patients have not been well studied. The tendency of steroid hormones to promote the growth of certain cancers also raises questions about the safety of differing doses and drug combinations. Further clinical and laboratory study is needed to better establish safety and dosing guidelines in transgender patients.

What Constitutes Sexual Dissatisfaction for Trans Masculine and Nonbinary Individuals: A Qualitative Study

The present study is aimed at understanding how trans masculine and nonbinary individuals describe aspects of their sexual dissatisfaction. Previous studies on cisgender sexual dissatisfaction have utilized narrow definitions of dissatisfaction, operationalizing it in opposition to sexual satisfaction. Moreover, the pervasive focus on the outcomes of medical intervention steps in prior sexual dissatisfaction research with trans masculine participants ignored the experiences of individuals who do not desire a medical transition or live outside of the gender binary. Participants in the current study represented a non-clinical sample of 358 trans masculine and nonbinary individuals who responded to the question: "In what ways are you dissatisfied with your sex life?" Thematic analysis revealed six overarching themes for participant dissatisfaction: 1) difficulty with orgasm, 2) partner dynamics, 3) trauma, 4) desire for different body parts, 5) gender dysphoria, and 6) medical transition. Discussion focuses on the ways in which clinicians can utilize the current findings to decrease the sexual dissatisfaction of trans masculine and nonbinary individuals.

Trans* Pregnancy and Lactation: A Literature Review from a Nursing Perspective

Pregnancy and lactation involve two aspects that are socially and culturally associated with women. However, there are a few biological differences between male and female breast tissue. Lactation and pregnancy are viable processes that do not depend on sex. Even for the latter, it is only necessary to have an organ capable of gestation. Ways to favor mammogenesis and lactogenesis in trans* women have been established. There are protocols to promote lactation in trans* women, usually used for adoptive mothers or those whose children have been born through gestational surrogacy. Chestfeeding a baby could be the cause of feelings as diverse as gender dysphoria in the case of trans* men, and euphoria and affirmation of femininity in trans* women. This study involves a review of the available scientific literature addressing medical aspects related to pregnancy and lactation in trans* individuals, giving special attention to nursing care during perinatal care. There are scarce studies addressing care and specifically nursing care in trans* pregnancy and lactation. Our study indicates the factors that can be modified and the recommendations for optimizing the care provided to these individuals in order to promote and maintain the lactation period in search of improvement and satisfaction with the whole process.

Hormone replacement therapy: informed consent without assessment?

Florence Ashley has argued that requiring patients with gender dysphoria to undergo an assessment and referral from a mental health professional before undergoing hormone replacement therapy (HRT) is unethical and may represent an unconscious hostility towards transgender people. We respond, first, by showing that Ashley has conflated the self-reporting of symptoms with self-diagnosis, and that this is not consistent with the standard model of informed consent to medical treatment. Second, we note that the model of informed consent involved in cosmetic surgery resembles the model Ashley defends, and that psychological assessment and referral is recognised as an important aspect of such a model. Third, we suggest that the increased prevalence of psychiatric morbidity in the transgender population arguably supports the requirement of assessment and referral from a mental health professional prior to undergoing HRT.

In the Footsteps of Teiresias: Treatment for Gender Dysphoria in Children and the Role of the Courts

The Family Court of Australia has stepped back from a previously perceived need for involvement in the approval of stage 1 and stage 2 treatments, for children requiring gender transformation. At present those children and their families who are in agreement need not seek authorisation of the Family Court to undertake either Stage 1 (pubarche blockade with gonadotrophin-releasing hormone agonists) or Stage 2 treatment (cross-hormone therapy such as oestrogen for transgender males). Stage 1 treatment to suppress pubarche would nowadays be commenced at Tanner stage 2 which commences as early as 9.96 years in girls and 10.14 years in boys. Suppression of puberty continues until the age of 16 years when cross hormonal treatment commences. This article questions the assertion that suppression of puberty by GnRH analogues either in cases of precocious puberty or gender dysphoria is "safe and reversible" and argues that it warrants ongoing caution, despite the Family Court having broadly accepted that assertion.

Fanon and the New Paraphilias: Towards a Trans of Color Critique of the DSM-V

This essay places psychiatrist and philosopher Frantz Fanon's anti-colonial, anti-racist message from Peau Noire, Masques Blancs/Black Skin, White Masks (1952; 1967; 2008) in conversation with the new diagnoses of "Gender Dysphoria" and "Transvestic Disorder" in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-V). Specifically, the essay discusses sexologist Ray Blanchard's controversial theory of autogynephilia alongside Fanon's ambivalent rendering of transgender desire and interracial trans phenomenology in a crucial but frequently overlooked passage in Black Skin. Fanon's anti-colonial critique of psychiatry allows us to reconsider how Blanchard's theories on paraphilia engage with the foundational psychoanalytic concepts of identification and desire, as identified by the Freudian and Lacanian models and explored in the writings of Judith Butler, Catherine Millot, Charles Shepherdson, and others. By offering a fresh interpretation of the French text, this essay argues that a "trans of color critique" can benefit from Black Skin's unexpected insight into trans desire: Fanon's "man of color," who simultaneously undergoes a gender transition and a racial transformation, represents the literal embodiment of his critique of colonial racism. Given the role of the new paraphilias in the DSM-V, this essay concludes that a trans of color critique is well positioned to reinforce the anti-colonial message Fanon addressed to the psychiatric and psychoanalytical fields, which have tended to diagnose psychic injury while ignoring its causation, and which continue to neglect the fact that medical access is just as important as material support and security for minority subjects, in particular.

Revisiting the Link: Evidence of the Rates of Autism in Studies of Gender Diverse Individuals

Turban and van Schalkwyk assert in their Translations article, "'Gender Dysphoria' and Autism Spectrum Disorder: Is the Link Real?" that an over-representation of autism spectrum disorder (ASD) in gender dysphoria is unsupported based on current evidence. Turban and van Schalkwyk discuss 7 of the currently 19 available empirical studies (excluding reviews and case reports) of the over-occurrence of ASD and/or autism traits with gender dysphoria/diversity. They are correct to note that some ASD screeners may lack specificity; that is, a clinical-range total score could indicate non-ASD-related mental health conditions or other developmental difference. However, they do not account for the 7 available studies which specifically report rates of clinical diagnoses of ASD among unselected gender-diverse samples. We suggest also that many of the studies that assess ASD-symptoms in gender-diverse groups are more convincing than suggested by Turban and van Schalkwyk because they employ measures assessing the multi-dimensionality of ASD symptoms and report significant elevations not only for socially-related symptoms but also for the various components of restricted and repetitive behaviors and interests (RRBI) core to ASD. We come together to write this response as gender clinicians and researchers, autism clinicians and researchers, and key stakeholders, including autistic and autistic transgender self-advocates. We work and live with the co-occurrence of autism and gender diversity on a daily basis, and we are concerned that perpetuating misunderstanding about the co-occurrence places individuals at risk.

[About a case of gender dysphoria]

The concept of gender dysphoria is used to designate the dissatisfaction resulting from the conflict between gender identity and gender assigned at birth (genetic, gonadal, genital and morphological). The most frequently encountered psychopathologies include depressive disorders, anxiety, substance abuse, disorders of the personality, and they present a suicide attempt rate of 19 to 25%. Being a manifestation of low prevalence, this report aims to describe the case of a patient with gender dysphoria and comment on the experience of the therapeutic approach.

Qualitative Study on the Psychological Experiences of Trans-man and Trans-woman

Transsexuals have problems associated with self and gender identities, as well as with their relationships with specialists such as doctor and counsellors. On the basis of the principle of interpretative phenomenological analysis, an exploratory research was carried out on self by studying the psychological experiences of participants and their relationships with specialists. Consequently the following needs of the transsexuals were identified: (1) understanding and alleviation of grief, conflict, and anxiety associated with gender dysphoria; (2) recovery and improvement of self-esteem; (3) support in real-life experiences and measures related to social and legal issues, such as coming out; and (4) necessity of information provision at medical institutions and among peers. To meet these needs, it was suggested that the specialists should (1) help recover their self-esteem through the exploration of their sexual identities and maintain and improve their quality of life and (2) provide comprehensive support to alleviate the grief caused by gender dysphoria. Such support will facilitate affirmative psychological experiences of transsexuals, which will require further attention in the form of clinical intervention.
