- Grey and white matter volumes either in treatment-naive or hormone-treated transgender women: a voxel-based morphometry study(2018) SPIZZIRRI, Giancarlo; DURAN, Fabio Luis Souza; CHAIM-AVANCINI, Tiffany Moukbel; SERPA, Mauricio Henriques; CAVALLET, Mikael; PEREIRA, Carla Maria Abreu; SANTOS, Pedro Paim; SQUARZONI, Paula; COSTA, Naomi Antunes da; BUSATTO, Geraldo F.; ABDO, Carmita Helena NajjarMany previous magnetic resonance imaging (MRI) studies have documented sex differences in brain morphology, but the patterns of sexual brain differences in transgender women - male sex assigned at birth - with a diagnosis of gender dysphoria (TW) have been rarely investigated to date. We acquired T1-weighted MRI data for the following four (n = 80) groups: treatment-naive TW (TNTW), TW treated with cross-sex hormones for at least one year (TTW), cisgender men, and cisgender women (cisgender individuals as controls). Differences in whole-brain and regional white matter volume and grey matter volume (GMV) were assessed using voxel-based morphometry. We found lower global brain volumes and regional GMVs in a large portion of the posterior-superior frontal cortex in the cisgender women group than in the TTW and cisgender men groups. Additionally, both transgender groups exhibited lower bilateral insular GMVs than the cisgender women group. Our results highlight differences in the insula in both transgender groups; such differences may be characteristic of TW. Furthermore, these alterations in the insula could be related to the neural network of body perception and reflect the distress that accompanies gender dysphoria.

- Sexual compulsivity, anxiety, depression, and sexual risk behavior among treatment-seeking men in Sao Paulo, Brazil(2018) SCANAVINO, Marco D. T.; VENTUNEAC, Ana; ABDO, Carmita H. N.; TAVARES, Hermano; AMARAL, Maria L. S.; MESSINA, Bruna; REIS, Sirlene C.; MARTINS, Joao P. L. B.; PARSONS, Jeffrey T.Objective: There is a lack of studies on negative mood states and sexual risk behavior in men of all sexual orientations who seek treatment for excessive sexual behavior (ESB). We aim to examine sexual compulsivity (SC), anxiety, depression, and sexual risk behavior in a treatment-seeking sample of men and controls. Methods: We enrolled 88 (37 [42%] gay or bisexual and 51 [58%] heterosexual) ESB outpatients and 64 controls. Assessments included the Sexual Compulsivity Scale (SCS), the Beck Anxiety Inventory (BAI), the Beck Depression Inventory (BDI), and sexual risk behaviors. Results: Compared to controls, ESB outpatients showed increased SC, anxiety, and depression, which were correlated. Regarding sex with casual partners, ESB outpatients reported more sexual intercourse, a greater number of partners, more anal intercourse, and unprotected anal intercourse. Anxiety, depression, and SC were associated with protected vaginal intercourse with a main partner, whereas they were associated with unprotected anal intercourse with a casual partner. Depression was associated with unprotected vaginal intercourse with a casual partner. Condomless anal intercourse was predicted by SC and was also reported by the heterosexual ESB outpatients (36%). Conclusion: The data contribute to the field by providing information on men of all sexual orientations who are searching for mental healthcare. The connections among these psychopathological factors and sexual risk behavior have implications for public health, clinicians, and research.
