RESUMEN
OBJECTIVES: Despite regular gender-affirming hormone therapy (GAHT), the presence of uterine bleeding can occur occasionally and cause profound discomfort. This study aimed to evaluate the histologic features and immunohistochemical expression of estrogen (ER), progesterone (PR), and androgen receptors (AR) in the endometrium and myometrium of transgender men receiving testosterone therapy and relate them to clinical and hormonal characteristics. DESIGN: Retrospective cross-sectional study. METHODS: Thirty-four transgender men undergoing gender-affirming surgery were included. Clinical, sociodemographic, and laboratory data as well as anatomopathological and immunohistochemical findings were evaluated. RESULTS: The participants' mean age was 42.35 (SD, 10.00) years, and body mass index was 28.16 (SD, 5.52) kg/m2. The mean GAHT duration before surgery was 5.36 (SD, 3.24) years. The mean testosterone levels were 814.98 (SD, 407.13) ng/dL, and estradiol levels were 55.22 (SD, 25.27) pg/mL. The endometrium was atrophic in 61.8%, proliferative in 17.6%, and secretory in 20.6%. Immunohistochemical receptor analysis revealed that endometrial epithelial cells expressed ER (90%) and PR (80%), with a lower expression of AR (30%). In stromal tissue, the median ER, PR, and AR expression was lower than that in the epithelium (60%, 70%, and 25%, respectively). The myometrium showed high expression of PR (90%) and ER (70%), with the highest expression of AR (65%) being localized to this region. CONCLUSIONS: In the present study, GAHT induced an atrophic condition of the endometrium in two-thirds of the transgender men, with a limited AR expression in the endometrial region. The present results suggest that testosterone-based GAHT for a mean of 5 years is safe in transgender men achieving amenorrhea.

PURPOSE: While it is common for menstrual cycles to cease within the initial 6 months of treatment, there are instances where some transgender men may not experience this cessation. We analyzed transgender men undergoing gender-affirming hormone therapy (GAHT) with testosterone who experienced breakthrough bleeding in order to identify the factors associated with this condition. METHODS: In this case-control study, 24 transgender men in the case group and 48 in the control group were assessed for clinical, sociodemographic, hormonal, and body composition variables using dual-energy X-ray absorptiometry. All participants had been on GATH for at least 6 months. RESULTS: A few transgender men experienced persistent breakthrough bleeding, which was associated with decreased testosterone levels and free androgen index (FAI) compared with controls (p = 0.002 and p = 0.008, respectively). Among individuals with breakthrough bleeding, 50% had testosterone levels below the lowest tertile calculated for the sample, compared with 18.8% on controls (p = 0.007). After therapy adjustment, testosterone levels increased compared with the values obtained in the initial bleeding episode (p = 0.031). Eight transgender men required the addition of an oral progestogen to achieve amenorrhea, and these individuals had higher BMI than those in whom the adjustment of the parenteral testosterone dose was adequate (p = 0.026). A univariate prevalence ratio analysis revealed a negative association of persistent bleeding with testosterone levels (p = 0.028) and FAI levels (p = 0.019). CONCLUSION: Higher BMI and lower levels of testosterone and FAI were the main factors associated with breakthrough bleeding in transgender men.

Introdução: A cirurgia de adequação genital tem se mostrado uma opção segura e confiável, com redução drástica na disforia e melhora da qualidade de vida das pessoas transgênero. A técnica mais estudada e utilizada é a inversão peniana com suas modificações, com aparência estética e funcionalidade adequadas, porém sem padronização da técnica cirúrgica. Índices de até 38% de satisfação parcial e 15% de insatisfação podem levar até 66% dos casos a realizar procedimentos adicionais. O objetivo é sugerir refinamentos estéticos na aparência da vulva e comparar com algumas das técnicas descritas, buscando aumentar a satisfação estética e funcional pós-operatória. Métodos: Estudo retrospectivo com 7 pacientes submetidas à cirurgia de readequação sexual entre agosto de 2017 e fevereiro de 2018. O clitóris é feito com a glande em formato de tridente, utilizando a coroa para construir os corpos cavernosos do clitóris e aumentar a área de sensação erógena. Faixa de prepúcio é usada para aumentar a cobertura do clitóris e cobrir a face interna dos pequenos lábios, que são definidos com o uso de suturas. Resultados: Sensibilidade adequada e satisfação com o resultado e capacidade de orgasmo em todas as pacientes observadas. Não houve estenose, fístula ou necrose do clitóris com essa técnica. Somente 1 caso precisou de procedimento adicional para melhor definição estética. Conclusão: A técnica apresentada tem alta satisfação das pacientes e sensibilidade erógena, com algumas vantagens em relação a outras técnicas. Porém, estudos prospectivos com número maior de pacientes são necessários para definir a técnica cirúrgica mais efetiva.
Introduction: Sex reassignment surgery is a reliable and safe option, which has drastically reduced dysphoria and improved the quality of life of transgender individuals. The most studied and used technique is penile inversion with modifications, which results in appropriate esthetic appearance and functionality, but the surgical technique has not been standardized. Partial satisfaction rates up to 38% and dissatisfaction rates of 15% may cause up to 66% of cases to undergo additional procedures. The objective is to suggest esthetic refinements to the appearance of the vulva and compare some of the techniques described, seeking to increase the postoperative esthetic and functional satisfaction. Methods: A retrospective study with 7 patients undergoing sex reassignment surgery between August 2017 and February 2018 was conducted. The clitoris is constructed with the glans in the form of a trident, using the corona to build the corpus cavernosa of the clitoris and increase the area of erogenous sensation. A section of the prepuce is used to increase the coverage of the clitoris and cover the inner surface of the labia minora, which are defined with the use of sutures. Results: Adequate sensitivity and satisfaction with the result and capacity of orgasm in all patients were observed. There was no stenosis, fistula, or necrosis of the clitoris with this technique. Only 1 case needed an additional procedure for better esthetic definition. Conclusion: The technique presented leads to high patient satisfaction and erogenous sensitivity, with some advantages compared to other techniques. However, prospective studies with larger numbers of patients are needed to define a more effective surgical technique.
