Online Intervention for Transgender/Nonbinary Young Adults' Experiences With Alcohol and Romantic Relationships

The objective of this study is to learn more about Whole Selves, an interactive online resource ("intervention") to help transgender and/or nonbinary young adults reflect on their experiences and goals related to both alcohol use and romantic relationships. Existing online interventions focused on alcohol use often aren't a good fit for trans/nonbinary people, and existing relationship education programs don't account for how being trans/nonbinary might influence someone's relationships. For these reasons, the investigator is working with trans/nonbinary young adults and other community stakeholders to create a new intervention specifically for trans/nonbinary young adults. The goals of this clinical trial are to: 1. Find out what transgender/nonbinary young adults think of the Whole Selves intervention in order to improve it 2. See whether the Whole Selves intervention seems to work as expected 3. Help the investigator make plans for a bigger clinical trial of the Whole Selves intervention, which could tell us how well it works In this study, participants will use the Whole Selves intervention; complete online surveys about themselves, their romantic relationship experiences, their mental health, their alcohol use; and provide feedback on the Whole Selves intervention.

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.

Sexual Functioning After Erection Prosthesis Placement in Post Phalloplasty Transgender Persons

This study aims to explore sexual satisfaction among transgender men and their partners following the placement of erectile prostheses after phalloplasty. While phalloplasty can create a neophallus, the lack of natural erectile tissue often necessitates the use of erectile aids, including internal prostheses. However, these prostheses, originally designed for cisgender men, face challenges when used in transgender patients, such as higher risks of complications, infections, and mechanical failures. Despite these issues, some studies report high patient satisfaction, though partner satisfaction rates are significantly lower. The study will use validated and non-validated questionnaires to assess satisfaction with various types of erectile prostheses, addressing the gap in understanding how these devices impact the sexual and relational functioning of both transgender men and their partners. These questionnaires will be provided to all included patients that are minimum 6 months after placement of an internal erection prosthesis and have a functional erection prosthesis in place

Erectile Aid Use in Post-phalloplasty and Post-metoidioplasty Transgender Patients

This study seeks to explore the various methods used by transgender men for sexual intercourse following phalloplasty or metoidioplasty, focusing on their satisfaction with different erectile aids, as well as the satisfaction of their partners. Phalloplasty and metoidioplasty are gender-affirming surgeries that often require additional aids to achieve the desired sexual function, particularly for penetration. While internal erectile prostheses are common after phalloplasty, they come with high complication rates, leading some patients to opt for non-surgical aids. However, the effectiveness and comfort of these aids are not well-documented. This study aims to fill this gap by examining the types of aids transgender men use, how well these aids meet their sexual needs, and how satisfied both they and their partners are with the outcomes, providing much-needed insight for healthcare providers and patients alike.

Epithesis Versus Prosthesis in Post-phalloplasty Transgender Patients.

Transgender and gender diverse (TGD) individuals most often choose for phalloplasty as a means to create masculine external genitalia. The neophallus created in phalloplasty is usually insufficient for penetrative sexual intercourse due to the lack of erectile structures. Therefore, implantation of an internal erectile prosthesis or use of an external device or epithesis is required. Internal prostheses are the main method for attaining penile rigidity after phalloplasty, but they carry a high risk of complications. Previous research has shown that up to 22% of prostheses for cisgender men were explanted due to various reasons, including infection, erosion, and malfunction within 20 months. The lack of reliable and durable erectile devices leads to a large proportion of patients either choosing phalloplasty but never going for the placement of an erectile prosthesis or completely abandoning the idea of GGAS under the form of phalloplasty. Secondarily, TGD individuals may be concerned about complication rates and likely need for additional surgeries associated with penile implant surgery. Therefore, alternative options for transgender and gender non-conforming patients after phalloplasty are needed. These alternatives may be surgical or non-surgical. External penile epitheses or penile splints were originally designed for cisgender men with erectile dysfunction but have been used experimentally by post-phalloplasty transgender men. While there is no data on the usability and durability of penile epitheses in a TGD population, they may be a viable alternative to an internal penile prosthesis after phalloplasty. Penile lifters or splints, marketed as ElatorTM or ErektorTM, are commercially available and consist of two rigid rings connected by rigid metal rods. The biggest of two rings is placed around the base of the phallus, and the second ring is placed behind the coronal ridge. By connecting the rods to the ring at the base of the penis, tension and rigidity between the two rings is created, allowing the user to penetrate their partner and remove the device after intercourse. The current study aims to extend the knowledge on these external devices by comparing them to the implantation of an internal penile prosthesis in post-phalloplasty transgender patients.
