Hypoactive sexual desire in transsexual women: prevalence and association with testosterone levels

Sexual Function in Post-surgical Transgender and Gender Diverse Individuals

Surgical treatment for gender dysphoria consists of facial, chest, and genital surgery. Chest and genital gender affirmation surgeries alter the form and function of the native organs. This can have a profound impact on sexual function for transgender and gender- diverse individuals. In this article, the authors will discuss the impacts that chest and genital gender affirmation surgeries can have on sexual function.

Sex & relationships in trans people

Everyone has sexual rights and is entitled to enjoy sex, regardless of gender identity or expression. It is therefore encouraging to witness a recent growth in research on sexuality in transgender individuals. We provide a short overview of extant research on sex and relationships in this population and argue that current research has mostly been conducted from a medical and functional approach; there is a strong focus on negative experiences and prevention; and there is a lack of data regarding psychological and socio-relational variables. Furthermore, many studies have been conducted in a cis- and hetero-normative setting and have methodological shortcomings such as applying questionnaires that have not been validated in a transgender population. We encourage researchers to expand their focus to positive variables such as sexual pleasure and (in accordance with the biopsychosocial model) investigate subjective experiences and relationship variables when studying sexuality in transgender individuals.

Changes in Serum Testosterone and Adrenal Androgen Levels in Transgender Women With and Without Gonadectomy

BACKGROUND

Initiating feminizing gender-affirming hormone therapy (GAHT) in transgender women causes a steep decline in serum testosterone. It is unknown if testosterone concentrations change further and whether adrenal androgen levels change during feminizing GAHT and after gonadectomy. This limits clinical decision making in transgender women with symptoms attributed to GAHT or gonadectomy.

METHODS

Transgender women (n = 275) initiating estradiol and cyproterone acetate (CPA) were included at baseline, and had follow-up visits after 3 months, 12 months, and 2 to 4 years. During follow-up, 49.5% of transgender women underwent a gonadectomy. Total testosterone (TT), dehydroepiandrosterone (DHEA), dehydroepiandrosterone sulfate (DHEAS), and androstenedione (A4) were measured using liquid chromatography tandem mass spectrometry.

RESULTS

After 3 months of GAHT, mean TT, calculated free testosterone (cFT), and A4 decreased by 18.4 nmol/L (95% CI, -19.4 to -17.4, P < 0.001 [ie, -97.1%]), 383 pmol/L (95% CI, -405 to -362, P < 0.001 [ie, -98.3%]), and 1.2 nmol/L (95% CI, -1.4 to -1.0, P < 0.001 [ie, -36.5%]), respectively, and remained stable thereafter. DHEA and DHEAS decreased by 7.4 nmol/L (95% CI, -9.7 to -5.1 [ie, -28.0%]) and 1.8 µmol/L (95% CI, -2.2 to -1.4 [ie, -20.1%]), respectively, after 1 year and did not change thereafter. After gonadectomy, CPA therapy is stopped, which induced no further change in TT, cFT, DHEA, DHEAS, and A4 compared with those who did not undergo gonadectomy.

CONCLUSIONS

Our findings confirm that after an initial drop, testosterone levels in transgender women remain stable. Adrenal androgens decrease in the first year of CPA and estrogen supplementation and remain unchanged after gonadectomy. Androgens did not change after gonadectomy and cessation of CPA. Correlates with clinical symptoms remain to be elucidated.

Pleasure please! Sexual pleasure and influencing factors in transgender persons: An ENIGI follow-up study

Background: While the importance of sexual pleasure for physical and mental health becomes increasingly evident, research on sexual pleasure in transgender persons is lacking. Recently, the first version of the Amsterdam Sexual Pleasure Index (ASPI Vol. 0.1) was validated in cisgender persons. This questionnaire aims to assess the tendency to experience sexual pleasure independent of gender, sexual orientation or anatomy. Aim: The aims of this study were threefold. First, to perform exploratory scale validation analyses of the ASPI in transgender persons. Secondly, to compare transgender sexual pleasure scores to reference data in cisgender persons. Finally, to identify factors that are associated with sexual pleasure. Methods: In a follow-up study conducted within the European Network for the Investigation of Gender Incongruence (ENIGI), online questionnaires were distributed to persons who had a first clinical contact at gender clinics in Amsterdam, Ghent or Hamburg four to six years earlier. Internal consistency of the ASPI was assessed by calculating McDonald's omega (ω_t). ASPI scores were compared to scores from the cisgender population using a one sample t-test, and linear regressions were conducted to study associations with clinical characteristics, psychological wellbeing, body satisfaction and self-reported happiness. Results: In total, 325 persons filled out the ASPI. The ASPI showed excellent internal consistency (ω_t, all: 0.97; transfeminine: 0.97, transmasculine: 0.97). Compared to data from cisgender persons, transgender participants had significantly lower total ASPI scores (i.e., lower sexual pleasure; transgender vs. cisgender, mean(SD): 4.13(0.94) vs. 4.71(0.61)). Lower age, current happiness and genital body satisfaction were associated with a higher tendency to experience sexual pleasure. Conclusion & discussion: The ASPI can be used to assess the tendency to experience sexual pleasure and associated factors in transgender persons. Future studies are needed to understand interplaying biopsychosocial factors that promote sexual pleasure and hence transgender sexual health and wellbeing.

Daily Sexual Behavior, Sexual Esteem, and Body Image in Transgender and Cisgender Individuals

Multiple surveys have suggested that transgender individuals show lower sexual well-being than cisgender individuals. Most studies, however, are limited in terms of ecological validity and memory bias and cross-sectional in nature. These issues are less prevalent in diary studies monitoring responses over time at home. For three weeks, 47 transgender (M age = 29.00, SD = 11.62) and 52 cisgender individuals (M age = 32.90, SD = 11.44) reported daily on their sexual behavior, sexual esteem and body image. Using multilevel model analyses, we investigated the daily associations between these variables, and addressed differences between transgender and cisgender individuals. We found that in transgender individuals, intimacy predicted sexual esteem; sexual openness predicted sexual esteem and body image; and sexual esteem predicts intimacy, masturbation, and sexual openness on the daily level. While transgender individuals scored lower on daily sexual esteem and body image than cisgender individuals, groups did not differ in daily sexual behavior. They also did not differ in any of the predictive relations described above, but we did find that the association between masturbation and body image was moderated by a cisgender identity, and sexual esteem predicted sexual activity more positively in cisgender compared to transgender individuals. These results complement findings from cross-sectional studies and indicate how transgender individuals struggling with sexuality can increase sexual openness. Implications for clinical practice are that clinicians discussing sexuality with their transgender patients should not define sexual activity too narrowly, and that sexual esteem might be a relevant factor in determining sexual behavior.

Sexual Function of Transgender Women After Gender Affirming Surgery: A Mini Review

BACKGROUND

A transgender person has a gender identity opposite to the sex assigned at birth. Transgender individuals may have altered sexual function (SF) due to psychosocial factors related to body image distortion, shame, and dissatisfaction with genital appearance, and these conditions can increase the risk of sexual dysfunction. This study aimed to characterize the SF of trans-women after gender affirming surgery.

METHODS

We reviewed the Pubmed database for studies published between January 2008 to December 2021.

RESULTS

17 studies were included, 4 were cross-sectional studies, 1 prospective study, 4 prospective cohort studies, five retrospective studies. The instruments used to evaluate the SF were Female Sexual Index (FSFI), semi-structured questionnaires, patients' opinion, Sexual Desire Inventory (SDI), Maudsley Marital Questionnaire-S, WHOQOL-100. The results of our review indicate there is weak evidence that gender affirming surgery improves the SF of trans-women.

CONCLUSION

We thus recommend that future studies use questionnaires that are validated for the assessment of the SF of trans-women to better determine the impact of genital surgery in this population. This article is protected by copyright. All rights reserved.

Evaluation of Mental Health and Satisfaction Following Transfeminine Gender-Affirming Surgery in Thailand

Purpose

Although many studies have shown that transgender women (TW) tend to have more depressive symptoms compared with the general population, the exact prevalence of major depressive disorder and contributing risk factors have not yet been studied, especially in those who have undergone gender-affirming genital surgery (GAS).

Methods

Every TW aged 20-60 years attending transgender clinics in the Thai Red Cross Society for postoperative checkup were invited to complete a self-report questionnaire, including (1) demographic data, (2) the Thai Patient Health Questionnaire 9 (PHQ-9), (3) satisfaction with psychosocial factors (relationship in family, friends, and society), sexual experiences and outcomes of gender-affirming treatments before and after GAS, and (4) contributing factors to depressive symptoms. Correlations between demographic data and depressive scores were tested. Paired t-test was used to compare pre- and post-GAS data.

Results

A total of 97 TW were analyzed, with 22.7% considered to have "major depression" (PHQ-9≥9) after GAS. Postoperative improvement in satisfaction with psychosocial factors and gender-affirming treatment outcomes were observed, especially in sexual experience. Depression severity was found to be negatively correlated with age and sexual satisfaction. Notably, presence of male characteristics before surgery, poor social support and understanding, and postoperative surgical complications were greatly considered as factors contributing to depressive symptoms.

Conclusion

Compared with non-GAS TW, depression among those who underwent GAS in Thailand was lower but still significant and was linked to younger age and poor postoperative sexual experiences. These findings were supported by the number of qualitative assessments in the psychosexual domain and postoperative treatment outcomes. Clinical Trial Registration Number - TCTR20190904003.

The assessment of sexual wellbeing in treatment-seeking transgender individuals: a systematic review of the medical literature

Sexual-wellbeing is recognized as an important aspect of quality-of-life. Yet, no overview exists of which aspects of sexual-wellbeing have been assessed in trans individuals seeking or undergoing medical treatment, nor is it clear what tools are used to evaluate the effect of medical treatment on sexual-wellbeing. First, to identify which topics pertaining to sexual-wellbeing have been assessed in transgender individuals in a medical context. Second, to determine which tools have been used for measuring aspects of sexual-wellbeing. A conceptual framework of sexual-wellbeing, was used as reference. A literature search (in PubMed, Embase, Cochrane Library) was performed up to March 10th, 2020. Studies that assessed aspects of sexual-wellbeing in transgender individuals' medical context were included in this review. Specific sexual topics addressed in each study were extracted by two independent reviewers. Thematic analysis was performed to identify sexual themes. Additionally, tools used to measure topics related to sexuality in transgender individuals were identified. In 172 papers, a total of 178 topics related to sexual-wellbeing were identified. Ten overarching themes were identified; sexuality, enacted sexual script, sexual activities, sexual relations, sexual response cycle, genital function, sexual function, sexual pleasure, sexual satisfaction, and quality-of-sex-life. Functional aspects of sexuality are assessed most frequently. A variety of methods was used to evaluate aspects related to sexual-wellbeing in trans individuals and over 50 different tools were identified. Self-developed questionnaires were used most frequently (n = 80), followed by chart reviews (n = 50), self-developed structured interviews (n = 37) and physical examination (n = 13). 23 previously developed questionnaires were used, all of which were developed for a cisgender population. Many studies in trans individuals touch on topics related to sexual-wellbeing, however, a comprehensive conceptualisation of (10 themes of) sexual-wellbeing is still lacking. Still, no valid tool exists for assessing sexual-wellbeing in the trans population, but is much needed.

ESSM Position Statement "Sexual Wellbeing After Gender Affirming Surgery"

Introduction

Much has been published on the surgical and functional results following Gender Affirming Surgery (‘GAS’) in trans individuals. Comprehensive results regarding sexual wellbeing following GAS, however, are generally lacking.

Aim

To review the impact of various GAS on sexual wellbeing in treatment seeking trans individuals, and provide a comprehensive list of clinical recommendations regarding the various surgical options of GAS on behalf of the European Society for Sexual Medicine.

Methods

The Medline, Cochrane Library and Embase databases were reviewed on the results of sexual wellbeing after GAS.

Main Outcomes Measure

The task force established consensus statements regarding the somatic and general requirements before GAS and of GAS: orchiectomy-only, vaginoplasty, breast augmentation, vocal feminization surgery, facial feminization surgery, mastectomy, removal of the female sexual organs, metaidoioplasty, and phalloplasty. Outcomes pertaining to sexual wellbeing- sexual satisfaction, sexual relationship, sexual response, sexual activity, enacted sexual script, sexuality, sexual function, genital function, quality of sex life and sexual pleasure- are provided for each statement separately.

Results

The present position paper provides clinicians with statements and recommendations for clinical practice, regarding GAS and their effects on sexual wellbeing in trans individuals. These data, are limited and may not be sufficient to make evidence-based recommendations for every surgical option. Findings regarding sexual wellbeing following GAS were mainly positive. There was no data on sexual wellbeing following orchiectomy-only, vocal feminization surgery, facial feminization surgery or the removal of the female sexual organs. The choice for GAS is dependent on patient preference, anatomy and health status, and the surgeon's skills. Trans individuals may benefit from studies focusing exclusively on the effects of GAS on sexual wellbeing.

Conclusion

The available evidence suggests positive results regarding sexual wellbeing following GAS. We advise more studies that underline the evidence regarding sexual wellbeing following GAS. This position statement may aid both clinicians and patients in decision-making process regarding the choice for GAS. Özer M, Toulabi SP, Fisher AD, et al.

Sexual Dysfunction in Transgender People: A Systematic Review

Transgender people may choose to affirm their gender identity with gender-affirming hormone therapy (GAHT) and/or gender-affirming surgery (GAS). The effects of GAHT and GAS on sexual health in transgender people have not been well elucidated. This systematic review aimed to appraise the current scientific literature regarding sexual desire, arousal, orgasm, pain, and satisfaction in transmen and transwomen before, during, and after gender transition. Overall, sexual dysfunction is common in both transmen and transwomen. GAHT and GAS may help to improve sexual satisfaction. More studies that focus on sexual health in the transgender population are urgently needed.

Sexual Functioning of Transgender Females Post-Vaginoplasty: Evaluation, Outcomes and Treatment Strategies for Sexual Dysfunction

INTRODUCTION

Transfeminine genital reconstructive surgery is an important part of gender affirmation for many transgender women. Sexual health post-vaginoplasty is an important aspect of quality of life that can have a significant impact on overall well-being.

OBJECTIVES

The objective of this review is to provide a summary of the literature on the sexual outcomes of transgender females post-vaginoplasty and identify treatment strategies for those experiencing sexual dysfunction.

METHODS

A literature review was conducted with a focus on sexual health outcomes in transgender females post-vaginoplasty as well as treatment options for sexual dysfunction.

RESULTS

Penile inversion vaginoplasty with or without free skin grafts or local tissue flaps and intestinal vaginoplasty are the options available to patients interested in transfeminine genital reconstructive surgery with a neovagina. Sexual satisfaction post-vaginoplasty is high regardless of the vaginoplasty technique, however up to 29% of patients may be diagnosed with a sexual dysfunction due to associated distress with a sexual function disturbance. Hormone treatment, pelvic floor physical therapy, sex therapy, and sex surrogacy are treatment options for patients with sexual dysfunctions.

CONCLUSION

Patient reported outcome measures appropriately validated for this patient population are necessary to better understand sexual function outcomes, sexual dysfunction and treatment options for post-vaginoplasty patients.

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.

Body Image and Sexual Desire in the Context of Gender Affirming Therapy: Results of a Cross-sectional Multi-centered Transgender Study

It has been posited that gender-affirming treatment (GAT) can have an influence on body image and sexual desire in trans people. This study aims to examine associations between GAT and sexual desire as well as whether body image mediates the influences of gender-affirming hormone therapy (GAHT) or gender-affirming surgery (GAS) on sexual desire. A total of 210 individuals diagnosed with gender dysphoria (n = 105 of each gender) were assessed via self-assessment questionnaires in a cross-sectional study. Associations between GAT and sexual desire were investigated via multivariate analyses of variance. Mediation analyses were conducted to clarify associations between GAHT/GAS, body image, and sexual desire. GAHT was associated with increased sexual desire only in transmen. GAS had no significant effect on sexual desire in transmen and transwomen. Body image did not mediate the influence of GAHT or GAS on sexual desire in both groups. GAHT and GAS had significant direct effects on body image in both genders, whereas body image showed no significant direct effect on sexual desire. The results indicate that effects of GAT on sexual desire seem to be attributable to other factors than body image, such as the hormonal influence of testosterone in transmen.

Management of hypoactive sexual desire disorder in transgender women: a guide for clinicians

Hypoactive sexual desire disorder (HSDD) represents a common condition among transgender women. However, to date no specific guidelines for the management of HSDD in transgender persons are available. The aim of the present narrative Review is to evaluate evidence-based treatment for HSDD and to suggest treatment options for HSDD in transgender women. Clinically relevant publications on the management of HSDD (from 1985 to 2020) were searched in PubMed and Medline databases, using the following terms: "sexual desire", "sexual health", "HSDD", "transgender", "gender-affirming treatment", "sexual therapy", "testosterone treatment", "Central nervous system-active medications", and variants. Since sexual desire could be affected by several factors, a comprehensive assessment of HSDD- exploring biological, psychological, and social domains- is recommended, in order to identify possible predisposing, precipitating and maintaining factors. Among treatment options, transgender women may benefit of different sex therapy strategies and/or central nervous system-active medications-such as flibanserin, bremelanotide, bupropion and buspirone-and transdermal testosterone, bearing in mind that this option could be poorly accepted by patients due to the risk of virilizing effects. The lack of data regarding the efficacy of HSDD treatment options in transgender women emphasize the need for literature to focus more on this topic in the future.

Sexual Desire and Fantasies in the LGBT+ Community: a Focus on Bisexuals, Transgender, and Other Shades of the Rainbow

Purpose of Review

The purpose of this review is to summarize the current knowledge on sexual desire expressions, sexual orientation, and identity in understudied groups inside the LGBT+ community.

Recent Findings

Sexual desire and related problems have unique expressions in LGBT+ people which influence their sexual health. Emerging sex-positive approaches might be powerful and prominent tools to provide support and education on behalf of safer sex practices and marginalized sexualities. The importance of deepening LGBT+ sexualities and relationships, not only in lesbian women and gay men but also in all the other shades of the rainbow (bisexual, transgender, asexual, fluid, and non-binary/genderqueer identities), is strongly highlighted.

Summary

A lack of literature regarding sexual desire in LGBT+ people is reported. Results are controversial and research is still limited on this topic, with little information available about sexual and health needs of sexual minorities beyond gay and lesbian people.

European Society for Sexual Medicine Position Statement "Assessment and Hormonal Management in Adolescent and Adult Trans People, With Attention for Sexual Function and Satisfaction"

BACKGROUND

There is a general lack of recommendations for and basic information tailored at sexologists and other health-care professionals for when they encounter trans people in their practice.

AIM

We present to clinicians an up-to-date overview of clinical consensus statements on trans health care with attention for sexual function and satisfaction.

METHODS

The task force consisted of 7 clinicians experienced in trans health care, selected among European Society for Sexual Medicine (ESSM) scientific committee. The consensus was guided by clinical experience and a review of the available literature and by interactive discussions on trans health, with attention for sexual function and satisfaction where available.

OUTCOMES

The foci of the study are assessment and hormonal aspects of trans health care.

RESULTS

As the available literature for direct recommendations was limited, most of the literature was used as background or indirect evidence. Clinical consensus statements were developed based on clinical experiences and the available literature. With the multiple barriers to care that many trans people experience, basic care principles still need to be stressed. We recommend that health-care professionals (HCPs) working with trans people recognize the diversity of genders, including male, female, and nonbinary individuals. In addition, HCPs assessing gender diverse children and adolescents should take a developmental approach that acknowledges the difference between prepubescent gender diverse children and pubescent gender diverse adolescents and trans adults. Furthermore, trans people seeking gender-affirming medical interventions should be assessed by HCPs with expertise in trans health care and gender-affirming psychological practice. If masculinization is desired, testosterone therapy with monitoring of serum sex steroid levels and signs of virilization is recommended. Similarly, if feminization is desired, we recommend estrogens and/or antiandrogen therapy with monitoring of serum sex steroid levels and signs of feminization. HCPs should be aware of the influence of hormonal therapy on sexual functioning and satisfaction. We recommend HCPs be aware of potential sexual problems during all surgical phases of treatment.

CLINICAL IMPLICATIONS

This is an up-to-date ESSM position statement.

STRENGTHS & LIMITATIONS

These statements are based on the data that are currently available; however, it is vital to recognize that this is a rapidly changing field and that the literature, particularly in the field of sexual functioning and satisfaction, is limited.

CONCLUSION

This ESSM position statement provides relevant information and references to existing clinical guidelines with the aim of informing relevant HCPs on best practices when working with transgender people.

Sexual Desire Changes in Transgender Individuals Upon Initiation of Hormone Treatment: Results From the Longitudinal European Network for the Investigation of Gender Incongruence

INTRODUCTION

Several steps in the transitioning process may affect sexual desire in transgender people. This is often underexposed by those providing gender-affirming care.

AIM

To prospectively assess sexual desire during the first 3 years of hormonal therapy (HT) in transgender people.

METHODS

This prospective cohort study was part of the European Network for the Investigation of Gender Incongruence. At baseline, different psychological questionnaires were administered. Sex steroids were measured at each follow-up visit. Data were analyzed cross-sectionally and prospectively.

MAIN OUTCOME MEASURE

Prospective analysis of total, dyadic (with another person), and solitary (with oneself) sexual desire in 766 participants (401 transgender women [TW], 364 transgender men [TM]) was carried out using the Sexual Desire Inventory (SDI) questionnaire during a 3-year follow-up period, starting at the initiation of HT. Other factors associated with prospective changes were assessed.

RESULTS

In TW, total, dyadic, and solitary SDI scores decreased during the first 3 months of HT. However, after 36 months, total and dyadic SDI scores were higher than baseline scores. Solitary scores after 36 months were comparable with baseline scores. In TM, total, dyadic, and solitary SDI scores increased over the first 3 months, remaining stable thereafter. However, total and dyadic SDI scores after 36 months were comparable with baseline scores, whereas solitary scores remained higher than baseline. Factors associated with a prospective increase in SDI scores included having undergone gonadectomy, no longer experiencing menstrual bleeding or higher gender dysphoria levels at baseline (in TM only).

CLINICAL IMPLICATIONS

This study offers clear data on the time course of sexual desire after starting HT and thereby helps to inform people who want to start HT. Transgender people can be informed that changes in sexual desire after initiating HT are temporary. Over a longer period of time, the current research does not suggest induction of hypoactive sexual disorder in TW or long-term increased sexual desire in TM.

STRENGTH & LIMITATIONS

Strengths include the prospective design of this large multicentric study, the well-defined cohort, controlling for HT, sex steroids, and other factors. Limitations include performing a data lock, the absence of an objective measure of sexual desire, and the timing of laboratory measurements.

CONCLUSION

Gender-affirming HT only induces short-term changes in sexual desire in transgender people. Over a longer period of time, a net increase in dyadic sexual desire in TW receiving feminizing HT and sexual desire scores comparable with baseline in TM receiving virilizing HT, were observed.

Sexual Experiences in Transgender People: The Role of Desire for Gender-Confirming Interventions, Psychological Well-Being, and Body Satisfaction

We examined the role of gender-confirming treatment (GCT; i.e., hormonal treatment and genital surgery), psychological well-being, and body satisfaction in the sexual feelings and behaviors of transgender adults. A survey was conducted among a nonclinical sample of 325 male-to-female (MtF) and 251 female-to-male (FtM) Dutch adults (17-76 years, M_age = 41.87), divided into those with no GCT desire, those who desired (more) GCT, and those who completed GCT. Findings indicated that whereas GCT may positively affect sexual feelings, particularly in MtF persons, body satisfaction may play an even bigger role. Those without a GCT desire may experience particular difficulties in their sexual experiences.

Integrated and Gender-Affirming Transgender Clinical Care and Research

Transgender (trans) communities worldwide, particularly those on the trans feminine spectrum, are disproportionately burdened by HIV infection and at risk for HIV acquisition/transmission. Trans individuals represent an underserved, highly stigmatized, and under-resourced population not only in HIV prevention efforts but also in delivery of general primary medical and clinical care that is gender affirming. We offer a model of gender-affirmative integrated clinical care and community research to address and intervene on disparities in HIV infection for transgender people. We define trans terminology, briefly review the social epidemiology of HIV infection among trans individuals, highlight gender affirmation as a key social determinant of health, describe exemplar models of gender-affirmative clinical care in Boston MA, New York, NY, and San Francisco, CA, and offer suggested “best practices” for how to integrate clinical care and research for the field of HIV prevention. Holistic and culturally responsive HIV prevention interventions must be grounded in the lived realities the trans community faces to reduce disparities in HIV infection. HIV prevention interventions will be most effective if they use a structural approach and integrate primary concerns of transgender people (eg, gender-affirmative care and management of gender transition) alongside delivery of HIV-related services (eg, biobehavioral prevention, HIV testing, linkage to care, and treatment).

The medical care of the neovagina of transgender women: a review

For transgender women, genital adjustment surgery involves removal of the natal reproductive organs and creation of a neovagina, vulva and clitoris. We conducted a review of the medical literature in order to summarise the issues that can affect the health of the neovagina in the long term, and to make recommendations on how to manage these issues.

Has testosterone passed the test in premenopausal women with low libido? A systematic review

Background

There are limited evaluation and treatment options for low libido in premenopausal women. This review sought to evaluate the available evidence supporting the evaluation of testosterone serum levels and testosterone treatment of premenopausal women with low libido.

Methods

MEDLINE, PubMed, and ClinicalTrials.gov were searched for articles that referenced the evaluation of testosterone serum level and/or testosterone treatment on premenopausal women with low libido from 1995 to 2015. Additional references were obtained from the reference sections of other papers and from peer review. Studies that included only postmenopausal women were excluded. A total of 13 studies were reviewed in detail. Nine studies examined the relationship between testosterone serum levels and sexuality, an additional three studies examined the effect of testosterone treatment on premenopausal women with low libido, and one study examined both the topics.

Results

Six of the ten testosterone serum evaluation studies failed to show a significant association between testosterone serum level and libido. Only one out of four studies examining testosterone treatment in premenopausal women was able to show any clear improvement in libido; however, the effect was limited to only the intermediate dose of testosterone, with the low and high doses of testosterone not producing any effect.

Conclusion

The currently available evidence does not support testosterone serum evaluation or treatment in premenopausal women with low libido. Hence, further studies are warranted.

Endocrine care of transpeople part II. A review of cross-sex hormonal treatments, outcomes and adverse effects in transwomen

The treatment of transwomen relies on the combined administration of anti-androgens or GnRH analogues to suppress androgen production and thereby reduce male phenotypic characteristics together with oestrogens to develop female characteristics. In transwomen, synthetic oestrogens such as ethinyl oestradiol, as well as conjugated equine oestrogens (CEE), should be avoided to minimize thromboembolic risks especially in older transwomen and in those with risk factors. Currently, available short- and long-term safety studies suggest that cross-sex hormonal therapy (CHT) can be considered safe in transwomen improving the well-being and quality of life of these individuals. Long-term monitoring should aim to decrease cardiovascular risks and should include prostate and breast cancer screenings.

Hormone therapy in transgender adults is safe with provider supervision; A review of hormone therapy sequelae for transgender individuals

INTRODUCTION

Some providers report concern for the safety of transgender hormone therapy (HT).

METHODS

This is a systematic literature review of HT safety for transgender adults.

RESULTS

Current literature suggests HT is safe when followed carefully for certain risks. The greatest health concern for HT in transgender women is venous thromboembolism. HT among transgender men appears to cause polycythemia. Both groups experienced elevated fasting glucose. There is no increase in cancer prevalence or mortality due to transgender HT.

CONCLUSION

Although current data support the safety of transgender HT with physician supervision, larger, long-term studies are needed in transgender medicine.

Adiposity, chronic inflammation, and the prepubertal decline of sex hormone binding globulin in children: evidence for associations with the timing of puberty (Earlybird 58)

BACKGROUND

The regulation and role of SHBG in children are poorly defined. Here we investigated whether adiposity-related mechanisms regulate SHBG and whether SHBG levels are associated with the age of puberty.

METHODS

Longitudinal modelling of annual physiological and endocrine measurements from age 5 to 15 years in a cohort of 347 Plymouth schoolchildren.

RESULTS

SHBG levels were highest at age 5 years and then declined. Mean (SE) SHBG levels were higher in boys than girls at age 5 years [mean (SE) difference 7.68 (3.80) nmol/L; P = .045] but lower in boys by age 15 years [difference 12.19 (3.4) nmol/L; P < .001]. SHBG correlated inversely with adiposity [body mass index SD score (BMI SDS)], insulin, IGF-I, C-reactive protein (CRP), and leptin and positively with adiponectin but not with dehydroepiandrosterone sulphate, androstenedione, or T. In linear mixed models, five adiposity-related covariates (insulin, leptin, adiponectin, IGF-I, and CRP) all exerted significant main effects on SHBG (boys P = .04 to < .001; girls P = .007 to < .001). However, the further addition of BMI SDS rendered the effects of leptin, insulin, and adiponectin nonsignificant, whereas CRP and IGF-I remained significant. In separate models, the individual effects on SHBG of insulin, leptin, IGF-I, and adiponectin, but not CRP, were displaced by BMI SDS. Finally, in linear regression, BMI SDS little affected R(2) resulting from the five adiposity-related signals. Girls with lower SHBG levels at age 5 years reached Tanner stage 2 earlier, tended to have earlier LH secretion, and earlier age at peak height velocity and menarche. In contrast, boys with lower SHBG levels at age 5 years reached Tanner stage 2 earlier, but there were no relationships between SHBG and earlier onset of LH secretion or age at peak height velocity.

CONCLUSIONS

Adiposity-related endocrine mechanisms and chronic inflammation were associated with the prepubertal decline of SHBG, and lower SHBG levels anticipated earlier puberty. These findings may be relevant to the occurrence of earlier puberty in recent decades.

Trans people's experience of sexuality in the Netherlands: a pilot study

This pilot study explores the specificity of 12 Dutch trans people's experience of sexuality in order to provide new hypotheses and perspectives for future research. Emerging themes include the interconnection of sexual development with coming out and transition processes, the way incongruence between gender identity, gendered embodiment, and social perception of gender affected participants' experience of sexuality, and changes in physical sexual functioning after hormone therapy and/or various types of surgery. Our research design allowed for subjective accounts of trans people's experience of sexuality and detailed descriptions of changes in sexuality that occurred over time and throughout the coming out and transitioning processes.

Sexual desire in female-to-male transsexual persons: exploration of the role of testosterone administration

OBJECTIVE

To describe sexual desire in female-to-male transsexual persons post sex reassignment surgery (SRS). The associations between serum androgen levels and sexual desire are examined.

DESIGN

Single center cross-sectional study.

METHODS

Forty-five female-to-male transsexual persons post SRS completed a standardized questionnaire assessing sexual desire (Sexual Desire Inventory). In addition, participants were asked questions on sexual desire before starting hormone treatment and having SRS. Serum levels of testosterone, LH and sex hormone-binding globulin were measured on fasting morning serum samples.

RESULTS

In retrospect, 73.9% of the participants reported an increase in sexual desire after hormone treatment and SRS. Solitary sexual desire scores were significantly correlated with frequency of masturbation (r=0.835; P<0.001), whereas frequency of sexual intercourse with a partner was not. No direct associations were found between testosterone and solitary or dyadic sexual desire. However, ANOVA showed an independent effect of LH on solitary sexual desire (P<0.001). Post hoc analysis revealed that female-to-male transsexual persons with elevated levels of LH, indicating suboptimal testosterone therapy, reported significantly lower solitary sexual desire levels (than those with low LH levels; P=0.007). Suppressed LH levels were also associated with having a higher need for sexual activities (P=0.009) and a higher frequency of excessive sexual desire (P=0.007).

CONCLUSION

Most female-to-male transsexual persons report on a marked increase in sexual desire after testosterone treatment and SRS. No direct associations between levels of testosterone and solitary or dyadic sexual desire were found. However, measures of sexual desire were inversely associated with LH levels.

Contribution of androgen receptor sensitivity to the relation between testosterone and sexual desire: An exploration in male-to-female transsexuals

BACKGROUND

Low sexual desire is present in 1/3 of male-to-female transsexuals (post-operative male-to-female transsexual persons on estrogen replacement). Several studies report lower endogenous testosterone (T) levels in this group compared to community dwelling women. However, no relationship between T and sexual desire has been found in male-to-female transsexuals. Considering its role in androgen sensitivity, cytosine-adenine-guanine (CAG) trinucleotide repeat sequence in the androgen receptor (AR) might modify the relationship between T levels and sexual desire in male-to-female transsexuals.

AIM

This study aims to assess the potential contribution of the number of CAG repeats in the association between T and sexual desire in male-to-female transsexuals. MATERIAL, SUBJECTS, AND METHODS: Thirty-four post-operative male-to-female transsexuals participated in a cross-sectional study. The Sexual Desire Inventory, a questionnaire measuring sexual desire, was completed. Serum levels of total (TT) and free T (FT), DHEA-S, SHBG, and LH were measured in morning blood samples. AR gene CAG repeat length was determined by automated DNA fragment analysis of exon 1 of the AR gene.

RESULTS

The CAG repeat length ranged from 14 to 28 with a median of 21. CAG polymorphism was correlated with FT (r=0.389; p=0.023) but not with TT (r=0.191; p=0.280). The observed interaction between TT and CAG was significant only for solitary sexual desire (p=0.002). The interaction of CAG repeats and FT on sexual desire failed to reach significance.

CONCLUSIONS

We could not establish that CAG repeat length is a consistent modulating factor in the relationship between TT or FT and sexual desire in male-to-female transsexuals.
