Cheung AS, Lim HY, Cook T, Zwickl S, Ginger A, Chiang C, Zajac JD. Approach to Interpreting Common Laboratory Pathology Tests in Transgender Individuals. J Clin Endocrinol Metab 2021; 106:893-901. [PMID: 32810277 PMCID: PMC7947878 DOI: 10.1210/clinem/dgaa546] [Citation(s) in RCA: 25] [Impact Index Per Article: 8.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/14/2020] [Accepted: 08/11/2020] [Indexed: 12/30/2022]
Abstract
CONTEXT As the number of transgender (trans) people (including those who are binary and/or nonbinary identified) seeking gender-affirming hormone therapy rises, endocrinologists are increasingly asked to assist with interpretation of laboratory tests. Many common laboratory tests such as hemoglobin, iron studies, cardiac troponin, and creatinine are affected by sex steroids or body size. We seek to provide a summary of the impact of feminizing and masculinizing hormone therapy on common laboratory tests and an approach to interpretation. CASES Case scenarios discussed include 1) hemoglobin and hematocrit in a nonbinary person undergoing masculinizing hormone therapy; 2) estimation of glomerular filtration rate in a trans woman at risk of contrast-induced nephropathy; 3) prostate-specific antigen (PSA) in a trans woman; and 4) chest pain in a trans man with a cardiac troponin concentration between the reported male and female reference ranges. CONCLUSIONS The influence of exogenous gender-affirming hormone therapy on fat and muscle distribution and other physiological changes determines interpretation of laboratory tests that have sex-specific differences. In addition to affirmative practice to ensure a patient's name, gender, and pronoun are used appropriately, we propose that once individuals have commenced gender-affirming hormone therapy, the reference range of the affirmed gender be reported (and specified by treating clinicians) except for PSA or cardiac troponin, which are dependent on organ size. While suggestions may be challenging to implement, they also represent an opportunity to lead best practice to improve the quality of care and experiences of healthcare for all trans people.

Systematic review with a focus on the implications for sport participation. Br J Sports Med 2021; 55:865-872.

Abstract
Objectives We systemically reviewed the literature to assess how long-term testosterone suppressing gender-affirming hormone therapy influenced lean body mass (LBM), muscular area, muscular strength and haemoglobin (Hgb)/haematocrit (HCT). Design Systematic review. Data sources Four databases (BioMed Central, PubMed, Scopus and Web of Science) were searched in April 2020 for papers from 1999 to 2020. Eligibility criteria for selecting studies Eligible studies were those that measured at least one of the variables of interest, included transwomen and were written in English. Results Twenty-four studies were identified and reviewed. Transwomen experienced significant decreases in all parameters measured, with different time courses noted. After 4 months of hormone therapy, transwomen have Hgb/HCT levels equivalent to those of cisgender women. After 12 months of hormone therapy, significant decreases in measures of strength, LBM and muscle area are observed. The effects of longer duration therapy (36 months) in eliciting further decrements in these measures are unclear due to paucity of data. Notwithstanding, values for strength, LBM and muscle area in transwomen remain above those of cisgender women, even after 36 months of hormone therapy. Conclusion In transwomen, hormone therapy rapidly reduces Hgb to levels seen in cisgender women. In contrast, hormone therapy decreases strength, LBM and muscle area, yet values remain above that observed in cisgender women, even after 36 months. These findings suggest that strength may be well preserved in transwomen during the first 3 years of hormone therapy.

Abstract
BACKGROUND No data are available at present on the prevalence of gender dysphoria (trans-identity) in Germany. On the basis of estimates from the Netherlands, it can be calculated that approximately 15 000 to 25 000 persons in Germany are affected. Persons suffering from gender dysphoria often experience significant distress and have a strong desire for gender reassignment treatment. METHODS This review is based on pertinent publications retrieved by a selective search in the PubMed database employing the searching terms "transsexualism," "transgender," "gender incongruence," "gender identity disorder," "gender-affirming hormone therapy," and "gender dysphoria." RESULTS In view of its far-reaching consequences, some of which are irreversible, hormonal gender reassignment treatment should only be initiated after meticulous individual consideration, with the approval of the treating psychiatrist/psychotherapist and after extensive information of the patient by an experienced endo - crinologist. Before the treatment is begun, the patient must be extensively screened for risk factors. The contraindications include severe preexisting thromboembolic diseases (mainly if untreated), hormone-sensitive tumors, and uncontrolled pre - existing chronic diseases such as arterial hypertension and epilepsy. Finding an appropriate individual solution is the main objective even if contraindications are present. Male-to-female treatment is carried out with 17β-estradiol or 17β-estradiol valerate in combination with cyproterone acetate or spironolactone as an antiandrogen, female-to-male treatment with transdermal or intramuscular testosterone preparations. The treatment must be monitored permanently with clinical and laboratory follow-up as well as with gynecological and urological early-detection screening studies. Prospective studies and a meta-analysis (based on low-level evidence) have documented an improvement in the quality of life after gender reassignment treatment. Female-to-male gender-incongruent persons often have difficulty being accepted in a gynecological practice as a male patient. CONCLUZION Further prospective studies for the quantification of the risks and benefits of hormonal treatment would be desirable. Potential interactions of the hormone preparations with other medications must always be considered.

Abstract
Purpose of review Nephrologists are increasingly providing care to transgender individuals with chronic kidney disease (CKD). However, they may lack familiarity with this patient population that faces unique challenges. The purpose of this review is to discuss the care of transgender persons and what nephrologists should be aware of when providing care to their transgender patients. Sources of information Original research articles were identified from MEDLINE and Google Scholar using the search terms "transgender," "gender," "sex," "chronic kidney disease," "end stage kidney disease," "dialysis," "transplant," and "nephrology." Methods A focused review and critical appraisal of existing literature regarding the provision of care to transgender men and women with CKD including dialysis and transplant to identify specific issues related to gender-affirming therapy and chronic disease management in transgender persons. Key findings Transgender persons are at an increased risk of adverse outcomes compared with the cisgender population including mental health, cardiovascular disease, malignancy, sexually transmitted infections, and mortality. Individuals with CKD have a degree of hypogonadotropic hypogonadism and decreased levels of endogenous sex hormones; therefore, transgender persons with CKD may require reduced exogenous sex hormone dosing. Exogenous estradiol therapy increases the risk of venous thromboembolism and cardiovascular disease which may be further increased in CKD. Exogenous testosterone therapy increases the risk of polycythemia which should be closely monitored. The impact of gender-affirming hormone therapy on glomerular filtration rate (GFR) trajectory in CKD is unclear. Gender-affirming hormone therapy with testosterone, estradiol, and anti-androgen therapies changes body composition and lean body mass which influences creatinine generation and the performance for estimated glomerular filtration rate (eGFR) equations in transgender persons. Confirmation of eGFR with measured GFR is reasonable if an accurate knowledge of GFR is needed for clinical decision-making. Limitations There are limited studies regarding the intersection of transgender persons and kidney disease and those that exist are mostly case reports. Randomized controlled trials and observational studies in nephrology do not routinely differentiate between cisgender and transgender participants. Implications This review highlights important considerations for providing care to transgender persons with kidney disease. Additional research is needed to evaluate the performance of eGFR equations in transgender persons, the effects of gender-affirming hormone therapy, and the impact of being transgender on outcomes in persons with kidney disease.

Abstract
With a shift in the cultural, political, and social climate surrounding gender and gender identity, an increase in the acceptance and visibility of transgender individuals is expected. Anesthesiologists are thus more likely to encounter transgender and gender nonconforming patients in the perioperative setting. Anesthesiologists need to acquire an in-depth understanding of the transgender patient's medical and psychosocial needs. A thoughtful approach throughout the entirety of the perioperative period is key to the successful management of the transgender patient. This review provides anesthesiologists with a culturally relevant and evidence-based approach to transgender patients during the preoperative, intraoperative, and postoperative periods.

Abstract
The attention to transgender medicine has changed over the last decade and the interest is most likely going to increase in the future due to the fact that gender-affirming treatments are now being requested by an increasing number of transgender people. Even if gender-affirming hormone therapy (GAHT) is based on a multidisciplinary approach, this review is going to focus on the procedures adopted by the endocrinologist in an out-clinic setting once an adult patient is referred by another specialist for ‘gender affirming’ therapy. Before commencing this latter treatment, several background information on unmet needs regarding medical and surgical outcomes should be investigated. We summarized our endocrinological clinical and therapeutic approaches to adult transgender individuals before and during GAHT based on a non-systematic review. Moreover, the possible relationships between GAHT, gender-related pharmacology, and COVID-19 are also reported.

Abstract
CONTEXT The effect of gender-affirming hormone therapy (HT) on erythropoiesis is an area of priority in transgender health research. OBJECTIVE To compare changes in hematologic parameters and rates of erythrocytosis and anemia among transgender people to those of cisgender controls. DESIGN Longitudinal observational study. PARTICIPANTS AND SETTING We compared 559 transfeminine (TF) and 424 transmasculine (TM) people enrolled in 3 integrated health care systems to matched cisgender referents. INTERVENTIONS AND OUTCOME Hormone therapy receipt was ascertained from filled prescriptions. Hemoglobin (Hb) and hematocrit (Hct) levels were examined from the first blood test to HT initiation, and from the start of HT to the most recent blood test. Rates of erythrocytosis and anemia in transgender participants and referents were compared by calculating adjusted hazard ratios and 95% confidence intervals (CI). RESULTS In the TF group, there was a downward trend for both Hb and Hct. The corresponding changes in the TM cohort were in the opposite direction. TM study participants experienced a 7-fold higher rate (95% CI: 4.1-13.4) of erythrocytosis relative to matched cisgender males, and an 83-fold higher rate (95% CI: 36.1-191.2) compared to cisgender females. The corresponding rates for anemia were elevated in TF subjects but primarily relative to cisgender males (hazard ratio 5.9; 95% CI: 4.6-7.5). CONCLUSIONS Our results support previous recommendations that hematological parameters of transgender people receiving HT should be interpreted based on their affirmed gender, rather than their sex documented at birth. The clinical significance of erythrocytosis following testosterone therapy, as well as anemia following feminizing HT, requires further investigation.

Abstract
INTRODUCTION This review summarizes gender affirming medical and surgical care available to transgender individuals, along with proposals to improve medically and culturally appropriate care. AREAS COVERED Transgender individuals are those whose gender identity differs from that recorded at birth (usually based on visualization of external sexual anatomy). In order to align the body with the patient's gender identity, clinicians can provide hormone therapy (HT) to bring sex hormone levels to the range associated with the patient's gender identity. At steady state, monitoring for maintenance of levels, as well as for known risks and complications, is required. Treating clinicians should have knowledge of trans assessment criteria, hormone therapy, surgical options, primary care, and mental health needs of transgender patients. A narrative literature review was conducted using Pubmed and EMBASE with articles then selected for relevance. The initial search terms were: androgen suppression, antiandrogen, breast development, chest reconstruction, cisgender, estrogen, fertility preservation, gender-affirming surgery, gender identity, gender incongruence, genital reconstruction, hormone replacement, hyperlipidemia, orchiectomy, prolactin, prostate atrophy, spermatogenesis, spironolactone, testosterone, thrombogenesis, transgender, and virilization. EXPERT OPINION Although guidelines exist and examples of training are available, systematic formal training must be implemented to truly mainstream high-quality gender-affirming health care .

Abstract
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.

Effects of Gender-Affirming Hormone Therapy on Insulin Sensitivity and Incretin Responses in Transgender People. Diabetes Care 2020; 43:411-417. [PMID: 31740479 DOI: 10.2337/dc19-1061] [Citation(s) in RCA: 27] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/29/2019] [Accepted: 10/28/2019] [Indexed: 02/03/2023]
Abstract
OBJECTIVE The long-term influences of sex hormone administration on insulin sensitivity and incretin hormones are controversial. We investigated these effects in 35 transgender men (TM) and 55 transgender women (TW) from the European Network for the Investigation of Gender Incongruence (ENIGI) study. RESEARCH DESIGN AND METHODS Before and after 1 year of gender-affirming hormone therapy, body composition and oral glucose tolerance tests (OGTTs) were evaluated. RESULTS In TM, body weight (2.8 ± 1.0 kg; P < 0.01), fat-free mass (FFM) (3.1 ± 0.9 kg; P < 0.01), and waist-to-hip ratio (-0.03 ± 0.01; P < 0.01) increased. Fasting insulin (-1.4 ± 0.8 mU/L; P = 0.08) and HOMA of insulin resistance (HOMA-IR) (2.2 ± 0.3 vs. 1.8 ± 0.2; P = 0.06) tended to decrease, whereas fasting glucose (-1.6 ± 1.6 mg/dL), glucose-dependent insulinotropic polypeptide (GIP) (-1.8 ± 1.0 pmol/L), and glucagon-like peptide 1 (GLP-1) (-0.2 ± 1.1 pmol/L) were statistically unchanged. Post-OGTT areas under the curve (AUCs) for GIP (2,068 ± 1,134 vs. 2,645 ± 1,248 [pmol/L] × min; P < 0.01) and GLP-1 (2,352 ± 796 vs. 2,712 ± 1,015 [pmol/L] × min; P < 0.01) increased. In TW, body weight tended to increase (1.4 ± 0.8 kg; P = 0.07) with decreasing FFM (-2.3 ± 0.4 kg; P < 0.01) and waist-to-hip ratio (-0.03 ± 0.01; P < 0.01). Insulin (3.4 ± 0.8 mU/L; P < 0.01) and HOMA-IR (1.7 ± 0.1 vs. 2.4 ± 0.2; P < 0.01) rose, fasting GIP (-1.4 ± 0.8 pmol/L; P < 0.01) and AUC GIP dropped (2,524 ± 178 vs. 1,911 ± 162 [pmol/L] × min; P < 0.01), but fasting glucose (-0.3 ± 1.4 mg/dL), GLP-1 (1.3 ± 0.8 pmol/L), and AUC GLP-1 (2,956 ± 180 vs. 2,864 ± 93 [pmol/L] × min) remained unchanged. CONCLUSIONS In this cohort of transgender persons, insulin sensitivity but also post-OGTT incretin responses tend to increase with masculinization and to decrease with feminization.

Abstract
BACKGROUND Despite increasing demand for transgender healthcare, guidelines for cross-sex hormone therapy are based on low-level evidence only. As most data are based on international expert opinions, interpretations and practices vary significantly. AIMS To aid the development of Australian clinical guidelines, we aimed to identify cross-sex hormone therapy prescribing patterns among medical practitioners experienced in adult transgender healthcare. METHODS We conducted an anonymous online survey of experienced hormone prescribers who were members of the Australian and New Zealand Professional Association for Transgender Health (ANZPATH). RESULTS We received 35 responses from 43 individuals listed with ANZPATH. Mental health assessments prior to commencement of hormonal therapy were recommended by 80% of prescribers. The preferred first-line masculinising hormone therapy was intramuscular testosterone undecanoate (46% of respondents). The most commonly prescribed feminising agents were oral estradiol valerate (first line in 71.4%), with either spironolactone or cyproterone acetate. Most respondents (>90%) targeted sex steroid reference ranges of the affirmed gender, and 71.4% reviewed individuals every 2-3 months in the first year. Better training for doctors was seen as the most pressing priority for government funding, and 79.3% supported the development of local Australian-based guidelines. CONCLUSIONS Experienced hormone prescribers in Australia largely use medication regimens and monitor sex steroid levels and potential adverse effects of sex hormone therapy in accordance with broad, subjective recommendations listed in international guidelines. Additional practitioner training is necessary, and local Australian-based guidelines would offer specific, relevant guidance to clinicians in the initiation and monitoring of cross-sex hormone therapy for adult transgender individuals.

Abstract
The medical care of transgender patients relies on the use of sex hormones to develop and maintain the physical characteristics consistent with gender identity as the first step in transitioning. Hormonal therapy is usually continued indefinitely, even following gender-affirming surgeries. The use of hormonal treatments is associated with a multitude of positive effects as well as complications and side effects. The risk of venous thromboembolism (VTE) is a major concern. Transgender patients are often referred to coagulation specialists for advice regarding an individual patient's risk for VTE, especially if there is a personal or family history of VTE. Coagulation specialists need to be familiar with endocrine therapy including the goals of treatment and the VTE risks associated with currently used hormone regimens. We will review common referral questions and the available data and their limitations for the use of hormonal therapy in transgender patients focusing on the risk of VTE.

Abstract
Transgender (trans) women (TW) were assigned male at birth but have a female gender identity or gender expression. The literature on management and health outcomes of TW has grown recently with more publication of research. This has coincided with increasing awareness of gender diversity as communities around the world identify and address health disparities among trans people. In this narrative review, we aim to comprehensively summarize health considerations for TW and identify TW-related research areas that will provide answers to remaining unknowns surrounding TW's health. We cover up-to-date information on: (1) feminizing gender-affirming hormone therapy (GAHT); (2) benefits associated with GAHT, particularly quality of life, mental health, breast development and bone health; (3) potential risks associated with GAHT, including cardiovascular disease and infertility; and (4) other health considerations like HIV/AIDS, breast cancer, other tumours, voice therapy, dermatology, the brain and cognition, and aging. Although equally deserving of mention, feminizing gender-affirming surgery, paediatric and adolescent populations, and gender nonbinary individuals are beyond the scope of this review. While much of the data we discuss come from Europe, the creation of a United States transgender cohort has already contributed important retrospective data that are also summarized here. Much remains to be determined regarding health considerations for TW. Patients and providers will benefit from larger and longer prospective studies involving TW, particularly regarding the effects of aging, race and ethnicity, type of hormonal treatment (e.g. different oestrogens, anti-androgens) and routes of administration (e.g. oral, parenteral, transdermal) on all the topics we address.

Abstract
CONTEXT The impact of gender-affirming hormone therapy (HT) on cardiometabolic parameters is largely unknown. OBJECTIVE The effects of 1 year of treatment with oral or transdermal administration of estrogen (plus cyproterone) and transdermal or IM application of testosterone on serum lipid levels and blood pressure (BP) were assessed in transgender persons. DESIGN AND METHODS In this prospective, observational substudy of the European Network for the Investigation of Gender Incongruence, measurements were performed before and after 12 months of HT in 242 transwomen and 188 transmen from 2010 to 2017. RESULTS Mean values are reported. In transmen, HT increased diastolic BP (2.5%; 95% CI, 0.6 to 4.4) and levels of total cholesterol (TC; 4.1%; 95% CI, 1.5 to 6.6), low-density lipoprotein-cholesterol (LDL-C; 13.0%; 95% CI, 9.2 to 16.8), and triglycerides (36.9%; 95% CI, 29.8 to 44.1); high-density lipoprotein-cholesterol levels decreased (HDL-C; 10.8%; 95% CI, -14.0 to -7.6). In transwomen, HT slightly decreased BP (systolic BP, -2.6%, 95% CI, -4.2 to -1.0; diastolic BP, -2.2%, 95% CI, -4.0 to -0.4) and decreased levels of TC (-9.7%; 95% CI, -11.3 to -8.1), LDL-C (-6.0%; 95% CI, -8.6 to 3.6), HDL-C (-9.3%; 95% CI, -11.4 to -7.3), and triglycerides (-10.2%; 95% CI, -14.5 to -5.9). CONCLUSION Unfavorable changes in lipid profile were observed in transmen; a favorable effect was noted in transwomen. HT effects on BP were negligible. Long-term studies are warranted to assess whether and to what extent HT in trans individuals results in a differential effect on cardiovascular disease outcomes.

Abstract
Prescribing gender-affirming hormonal therapy in transgender men (TM) not only induces desirable physical effects but also benefits mental health. In TM, testosterone therapy is aimed at achieving cisgender male serum testosterone to induce virilization. Testosterone therapy is safe on the short term and middle term if adequate endocrinological follow-up is provided. Transgender medicine is not a strong part of the medical curriculum, although a large number of transgender persons will search for some kind of gender-affirming care. Because hormonal therapy has beneficial effects, all endocrinologists or hormone-prescribing physicians should be able to provide gender-affirming hormonal care.

Abstract
BACKGROUND The complete blood count (CBC) is a cornerstone of patient care. Several of the normal values for the components of the CBC differ by sex and, therefore, male-specific and female-specific reference intervals are required to interpret these laboratory results. Transgender individuals are often prescribed hormone therapy to affirm their gender, with resulting serum hormone concentrations similar to those of cisgender individuals. Gender-specific reference intervals for transgender men and women have not been established for any laboratory measurements, including hematology. We established clinically relevant hematological reference intervals for transgender individuals receiving stable hormone therapy. METHODS Healthy transgender individuals prescribed testosterone (n = 79) or estrogen (n = 93) for ≥12 months were recruited from internal medicine and primary care clinics that specialize in transgender medical care. Concentrations for hemoglobin, hematocrit, MCV, MCHC, and RDWCV, as well as counts for red cells, white cells, and platelets, were evaluated. Results were interpreted in reference to the overall distribution of values and relative to serum estradiol and total testosterone concentrations. Calculated reference intervals were compared to established cisgender reference intervals. RESULTS Regardless of serum hormone concentration, individuals prescribed testosterone or estrogen had hematology parameters that were not clinically different from cisgender males and females, respectively. CONCLUSION The hematology parameters for transgender men and women receiving stable hormone therapy should be evaluated against the cisgender male and cisgender female reference ranges, respectively and does not require concurrent sex hormone analysis. Care providers can utilize this observation to aid in interpretation of hematology laboratory values for transgender people.

Abstract
Abstract
BACKGROUND
Gender-affirming hormonal therapy consists of testosterone in transgender men and estrogens and antiandrogens in transgender women. Research has concluded that gender-affirming therapy generally leads to high satisfaction rates, increased quality of life, and higher psychological well-being. However, given the higher incidence of cardiometabolic morbidity and mortality in cisgender men compared with cisgender women, concerns about the cardiometabolic risk of androgen therapy have been raised.
CONTENT
A literature research was conducted on PubMed, Embase, and Scopus, searching for relevant articles on the effects of gender-affirming hormone therapy on cardiometabolic risk and thrombosis. After screening 734 abstracts, 77 full text articles were retained, of which 11 were review articles.
SUMMARY
Studies describing a higher risk for cardiometabolic and thromboembolic morbidity and/or mortality in transgender women (but not transgender men) mainly covered data on transgender women using the now obsolete ethinyl estradiol and, therefore, are no longer valid. Currently, most of the available literature on transgender people adhering to standard treatment regimens consists of retrospective cohort studies of insufficient follow-up duration. When assessing markers of cardiometabolic disease, the available literature is inconclusive, which may be ascribed to relatively short follow-up duration and small sample size. The importance of ongoing large-scale prospective studies/registries and of optimal management of conventional risk factors cannot be overemphasized.

Abstract
OBJECTIVE To retrospectively evaluate and compare safety and efficacy of short and long-acting testosterone (T) parenteral formulations over 5 years in transmen. DESIGN AND METHODS Fifty transmen between 21 and 42 years of age were enrolled. Twenty-five received T undecanoate 1000 mg IM (weeks 0 and 6 then every 12-16 weeks), and 25 received T enanthate 250 mg IM (every 3-4 weeks). Hormonal and biochemical parameters, anthropometric characteristics and blood pressure were assessed at baseline and then every 12 months. Body composition was evaluated at baseline and then after 1, 3 and 5 years of T treatment. Global satisfaction was assessed at baseline and after 1 and 5 years. RESULTS Both T formulations led to amenorrhoea in all subjects within 1 year of T administration. Both T treatments led to a similar increase in haemoglobin and haematocrit which always remained within the physiological range. T administration was associated with an increase in total cholesterol, low-density lipoprotein cholesterol and triglycerides and a slight reduction in high-density lipoprotein cholesterol. Coagulative and glucidic profiles and blood pressure did not change significantly in either group. Body weight and BMI showed a slight but not significant increase in both groups, while lean mass rose significantly in both groups. Global satisfaction was increased at years 1 and 5 in both groups. CONCLUSIONS Preliminary results from this pilot study suggest that administration of either TU or TE for 5 years in young transmen is both effective and safe. Our study presents the longest follow-up published so far reporting no adverse events and these data are consistent with previous reports with a shorter follow-up.
