Abstract
Background: Transgender men use exogenous androgen for male pattern virilization. Hysterectomy and bilateral salpingo-oophorectomy (HBSO) is performed to stop the endogenous estrogen secretion. Cardiovascular disease (CVD) risk has been shown to increase with long-term use of androgens and the removal of estrogen. We aimed to investigate the CVD risk in these individuals by measuring internal and common carotid artery intima-media thicknesses (CIMT). Methods: In this cohort study, data were collected from transgender men who had undergone HBSO and used androgens for at least two years (median treatment duration was 5 years in our research). Cisgender women in the same age range were selected as the control group. Demographics, vital signs, and hematological values of transgender patients and cisgender women subjects in the control group were noted. CVD markers were compared with sonographically measured CIMT values. Results: The mean age and body mass index (BMI) of the study group were 32.6 and 25.3, respectively. Weight, systolic-diastolic blood pressure, hemoglobin, hematocrit, low-density lipoprotein (LDL), serum triglyceride (TG), HbA1c levels, internal CIMT, and common CIMT values of the study group were higher, while the high-density lipoprotein (HDL) level was significantly lower compared the control group (p1 = 0.025, p2 = 0.010, p3 = 0.002, p4 = 0.001, p5 = 0.001, p6 = 0.012, p7 = 0.008, p8 = 0.007, p9 = 0.013, and p10 = 0.001). There was also an increase in the body weight, BMI, LDL, and TG levels of the study group after the testosterone treatment (p1 = 0.025, p2 = 0.019, p3 = 0.001, p4 = 0.001, and p5 = 0.001). Conclusions: We demonstrated that the use of testosterone therapy in transgender men is associated with higher CIMT values. While further investigation is needed to assess morbidity and mortality rates, we recommend that regular clinical and radiological examinations be performed in these individuals to accurately evaluate the risk of CVD.
