Long-Term Treatment of Transsexuals with Cross-Sex Hormones: Extensive Personal Experience
The Journal of Clinical Endocrinology & Metabolism, 2008
Context: Transsexuals receive cross-sex hormone treatment. Its short-term use appears reasonably safe. Little is known about its long-term use. This report offers some perspectives. Setting: The setting was a university hospital serving as the national referral center for The Netherlands (16 million people). Patients: From the start of the gender clinic in 1975 up to 2006, 2236 male-to-female and 876 female-to-male transsexuals have received cross-sex hormone treatment. In principle, subjects are followed up lifelong. Interventions: Male-to-female transsexuals receive treatment with the antiandrogen cyproterone acetate 100 mg/d plus estrogens (previously 100 g ethinyl estradiol, now 2-4 mg oral estradiol valerate/d or 100 g transdermal estradiol/d). Female-to-male transsexuals receive parenteral testosterone esters 250 mg/2 wk. After 18-36 months, surgical sex reassignment including gonadectomy follows, inducing a profound hypogonadal state. Main Outcome Measures: Outcome measures included morbidity and mortality data and data assessing risks of osteoporosis and cardiovascular disease. Results: Mortality was not higher than in a comparison group. Regarding morbidity, with ethinyl estradiol, there was a 6-8% incidence of venous thrombosis, which is no longer the case with use of other types of estrogens. Continuous use of cross-sex hormones is required to prevent osteoporosis. Androgen deprivation plus an estrogen milieu in male-to-female transsexuals has a larger deleterious effect on cardiovascular risk factors than inducing an androgenic milieu in female-tomale transsexuals, but there is so far no elevated cardiovascular morbidity/mortality. Low numbers of endocrine-related cancers have been observed in male-to-female transsexuals. Conclusions: Cross-sex hormone treatment of transsexuals seems acceptably safe over the short and medium term, but solid clinical data are lacking.
A long-term follow-up study of mortality in transsexuals receiving treatment with cross-sex hormones
European Journal of Endocrinology, 2011
ObjectiveAdverse effects of long-term cross-sex hormone administration to transsexuals are not well documented. We assessed mortality rates in transsexual subjects receiving long-term cross-sex hormones.DesignA cohort study with a median follow-up of 18.5 years at a university gender clinic.MethodsMortality data and the standardized mortality rate were compared with the general population in 966 male-to-female (MtF) and 365 female-to-male (FtM) transsexuals, who started cross-sex hormones before July 1, 1997. Follow-up was at least 1 year. MtF transsexuals received treatment with different high-dose estrogen regimens and cyproterone acetate 100 mg/day. FtM transsexuals received parenteral/oral testosterone esters or testosterone gel. After surgical sex reassignment, hormonal treatment was continued with lower doses.ResultsIn the MtF group, total mortality was 51% higher than in the general population, mainly from increased mortality rates due to suicide, acquired immunodeficiency sy...

Introduction. Data on the effects of cross-sex hormone therapy (CHT) are limited due to the low prevalence of gender dysphoria, small number of subjects treated at each center, lack of prospective studies, and wide variations in treatment modalities. Aim. The aim of this study is to report the short-term effects of CHT on hormonal and clinical changes, side effects, and adverse events in trans men (female-to-male gender dysphoric persons) and trans women (male-to-female gender dysphoric persons). Methods. This was a multicenter 1-year prospective study in 53 trans men and 53 trans women. Trans men received injections of testosterone undecanoate every 3 months. Trans women younger than 45 years received 50 mg cyproterone acetate (CA) and 4 mg estradiol valerate daily, whereas those older than 45 years received 50 mg CA daily together with 100 μg/24 hours transdermal 17-β estradiol. Main Outcome Measures. Sex steroids, prolactin, liver enzymes, lipids, hematocrit, blood pressure, anthropometrics, Ferriman and Gallwey score, and global acne grading scale were measured. Side effects, adverse events, and desired clinical changes were examined. Results. No deaths or severe adverse events were observed. Two trans men developed erythrocytosis, and two had transient elevation of the liver enzymes. Trans men reported an increase in sexual desire, voice instability, and clitoral pain (all P ≤ 0.01). Testosterone therapy increased acne scores, facial and body hair, and prevalence of androgenetic alopecia. Waist-hip ratio, muscle mass, triglycerides, total cholesterol (C), and LDL-C increased, whereas total body fat mass and HDL-C decreased. Three trans women experienced transient elevation of liver enzymes. A significant increase in breast tenderness, hot flashes, emotionality, and low sex drive was observed (all P ≤ 0.02). Fasting insulin, total body fat mass, and prolactin levels increased, and waist-hip ratio, lean mass, total C, and LDL-C decreased. Conclusions. Current treatment modalities were effective and carried a low risk for side effects and adverse events at short-time follow-up.

This follow-up study was carried out to validate the effectiveness of cross-gender hormone therapy embedded in a multistep treatment concept for transsexual patients. This therapy described in detail by the authors elsewhere and presented briefly below provides cross-gender hormone substitution to obtain an assimilation of secondary sex characteristics to the desired sex as quickly as possible. Personal and social background data of 46 male-to-female (M-to-F) and 42 female-to-male (F-to-M) patients passing through different stages of the treatment concept were included. In the Endocrinological Outpatient Clinic of the Max-Planck-Institute/Munich the effectiveness of cross-gender hormone replacement therapy as well as frequency and distribution of side effects were examined by follow-up examination of endocrinological parameters. Cross-gender hormones were administered either parenterally or orally. Blood samples were collected routinely after 2 to 6 months depending on the duration ...

The treatment of transsexual subjects is a challenging task for the endocrinologist who, in collaboration with the mental health professional and the surgeon, is called upon to confirm the diagnosis and adjust hormonal treatment aimed at suppressing endogenous sex hormones and to develop hormone characteristics of the desired gender. These guidelines are structured to provide evidence-based suggestions or, where evidence is lacking, expert recommendations on diagnostic procedures, hormonal treatment in adolescent and adult transsexuals, including long-term care and eligibility for surgery. The multidisciplinary approach to treatment, the additional diagnostic role of hormone administration and the need to maintain hormone levels within the physiological range are key suggestions stressed in the guidelines which are particularly important for an endocrinologist unfamiliar with this field. The need for psychological assessment before surgery is not common in many countries and should be stressed further in the guidelines. Some important issues such as time and method of hormone withdrawal before surgery together with when and which hormones should be administered after sex reassignment surgery has been completed, also remain unclear.

Gender dysphoria (GD) is characterized by discomfort with the assigned or birth gender and the urge to live as a member of the desired sex. The goal of medical and surgical treatment is to improve the well-being and quality of life of transpeople. The acquisition of phenotypic features of the desired gender requires the use of cross-sex hormonal therapy (CHT). Adult transmen are treated with testosterone to induce virilization. In adolescents with severe and persistent GD, consideration can be given to arresting puberty at Tanner Stage II and if dysphoria persists, CHT is generally started after 16 years of age. Currently available short- and long-term safety studies suggest that CHT is reasonably safe in transmen. Monitoring of transmen should be more frequent during the first year of cross-sex hormone administration reducing to once or twice per year thereafter. Long-term monitoring after sex reassignment surgery (SRS) includes annual check-ups as are carried out for natal hypogon...
