dc.description.abstractBackgroundCurrent evidence suggests that the etiology of gender dysphoria (GD) is multifactorial: this, however, remains unclear. Endocrine-disrupting chemicals (EDCs) are one of the etiological hypotheses.ObjectivesIn this study, we aimed to evaluate the urinary levels of bisphenol A (BPA), thiamethoxam, and fipronil in hormone-na & iuml;ve transmen compared with case-matched cis-women as well as the relation between sex hormone levels and EDCs.MethodsDrug-na & iuml;ve transmen diagnosed with GD and who were referred from the psychiatry outpatient clinic to the outpatient clinic of the Department of Endocrinology, Marmara University Hospital, were included in the study. These individuals were assessed for eligibility;38 drug-na & iuml;ve transmen and 22 cis-women were recruited as the control group. After anthropometric evaluation laboratory tests for FSH, LH, total testosterone, and estradiol were carried out, spot urine samples were collected to evaluate the urine metabolic excretion of BPA, thiamethoxam, and fipronil.ResultsWe found that androgens, total testosterone, androstenedione, and DHEAS levels were significantly higher in transmen than in cis-women. Thiamethoxam was considerably higher in cis-women than in transmen, whereas fipronil and BPA levels were similar in both groups. A negative correlation was found between thiamethoxam and testosterone and between thiamethoxam and BPA levels.ConclusionThe available data suggest that the EDCs that we are most exposed to in our lives are not the only factor in GD development. Even transmen who have not taken hormone replacement have high testosterone levels;however, the mechanism has not as yet been elucidated. The challenge is to determine whether this is a factor leading to GD or a condition that develops in common with GD.
