MaPGAS Decision Making

The goal of this clinical trial is to test a new online tool designed to provide clear and understandable information to help individuals considering Metoidioplasty and Phalloplasty Gender Affirming Surgery (MaPGAS)make informed decisions The main questions it aims to answer are: * How user-friendly is the decision aid for individuals considering metoidioplasty and phalloplasty? * Does using the decision aid reduce uncertainty and improve readiness for making surgery decisions compared to usual care? Participants in this study will: * Be randomly assigned to either 1) receive usual care or 2) test the web-based decision aid. * Share their feedback on the tool's usability and its helpfulness in supporting decision-making. * Complete surveys before and after using the decision aid to measure any changes in their decision-making process. Researchers will compare participants who used the decision aid with those who received standard care to see if the decision aid reduces decisional uncertainty and improves readiness for surgery.

Effects of Cross-sex Hormone Therapy on Eating Behavior, Metabolism, Energy Balance and Cardiovascular System

Current study aims to characterize five highly interconnected physiological systems in patients undergoing cross-sex hormone therapy - namely glucose and lipid metabolism, energy balance, eating behavior, functional brain networks involved in the regulation of eating behavior and the cardiovascular system - to gain novel insights into the effects of sex hormones on the human body. Gathered information will help to identify pathophysiological mechanisms for the development of overeating/obesity, insulin resistance, and cardiovascular disease. Secondarily, the relationships between the gut and oral microbiomes and metabolomes and circulating bacterial signatures will be investigated in relation to the other pervasive physiological systems. Current study is an observational study. The decision if the patient's request for cross-sex hormone therapy can complied with (i.e., if cross-sex hormone therapy is medically indicated) is made prior to the first contact with the study center and with the outpatients clinic for Endocrinology at the University Hospital in Leipzig. Decision ifor treatment is made according to national and international guidelines. Treatment of study participants with testosterone and estradiol/antiandrogens is not affected by the study. During the course of the study no invasive interventions are being performed.
