Persistent feelings of gender dysphoria (GD) are accompanied by distress and body dissatisfaction in most clinically referred adolescents and adults. Transition-related medical interventions (e.g., puberty suppression, hormones, or surgery) may alleviate body dissatisfaction. The aim of the present cross-sectional study was to compare multidimensional body image across clinically referred adolescents and adults undergoing different transition-related medical interventions. Two clinical samples of adolescents (n = 82) and adults (n = 120) referred to specialized departments of four different transgender health services in Germany participated in the study. In total, 202 individuals from the female-to-male (FtM individuals) and male-to-female (MtF individuals) spectrum aged 14-74 years were included at different stages of their transition. Four scales assessing multidimensional aspects of body image (measured by the Body Image Assessment Questionnaire, FBeK) were compared across three groups: sample, gender, and medical interventions (while controlling for age and treatment duration). The results indicated less favorable body image scores compared with the norm in both adolescents and adults with GD. Individuals who had undergone transition-related medical interventions presented a significantly better body image on two of the four scales. Differences according to gender and age were also present. These findings suggest that medical interventions, especially gender-affirming hormones and surgery, are generally beneficial to the body image in individuals with GD. However, not all of the less favorable outcomes in multidimensional body image were positively influenced by the treatment conditions and may thus benefit from additional integrative counseling before and during transition.

A closed-form solution for improved pattern recognition that reduces the training time to a single epoch (one presentation of each of the training patterns) is presented. It is shown that the corresponding hardware requirements are no greater than those for regular recognition under certain conditions. A simple example which shows that the generalization obtained with the closed-form method exceeds that obtained by a model that admits only diagonal transformations is discussed.

Background One of the most prominent etiological theories of gender incongruence in trans women proposes a paraphilic erotic target location error (ie, autogynephilia) as a causal factor in gynephilic (ie, exclusively gynephilic and bisexual) trans women. We hypothesized that a paraphilic erotic target location should manifest itself in various aspects of sexual behavior, solitary and dyadic sexual desire, and psychosexual experience. Aim To compare sexual behavior, sexual desire, and psychosexual experience of exclusively gynephilic and bisexual trans women with that of androphilic trans women to explore whether their sexuality differs substantially. Methods Trans women diagnosed with gender dysphoria (Diagnostic and Statistical Manual of Mental Disorders–5) were recruited at 4 transgender healthcare centers in Germany. The present study analyzed items on sexual behavior, desire, and experience of a self-report questionnaire, collected as part of a cross-sectional multicenter study. Main Outcomes Multiple aspects of sexuality were examined using self-constructed items. Sexual desire was measured using the Sexual Desire Inventory and psychosexual experience using the Multidimensional Sexuality Questionnaire. Results Significantly more exclusively gynephilic than androphilic trans women reported a history of sexual arousal in relation to cross-dressing. However, little evidence was found that gynephilic and androphilic sexual desire, behavior, and psychosexual experience differ profoundly. Interestingly, a statistically non-significant trend indicated that gynephilic trans women who had not yet undergone gender affirming surgery showed the highest levels of sexual desire (solitary and dyadic), whereas the opposite was the case for androphilic trans women. Clinical Translation Data of this study indicate that sexual orientation does not appear to be a good predicator for sexual behavior, desire, and psychosexual experience in trans women. Strengths and Limitations We investigated sexual desire and experience using standardized and evaluated measures such as the Sexual Desire Inventory and Multidimensional Sexuality Questionnaire. Future studies with a larger sample size should investigate how different gender affirming medical intervention might have diverging influences on sexual behavior, desire, and experience. Conclusion Ultimately, this study found little evidence for the hypothesis that sexual behavior, sexual desire, and psychosexual experience differ substantially in gynephilic (exclusively gynephilic and bisexual) and androphilic trans women.
