Active clinical trials for "Gender Dysphoria"

The voice is a reflection of our identity. In the case of transgender women, there may be a gap between perceived male voice and female appearance. Indeed, hormonal treatment in transgender women has no effect on the voice quality. This gap can have negative consequences on everyday life in banal situations such as telephonic contact leading to limited use of phone calls and social isolation. Differences between female and male voices seem to be socially determined and do not depend directly on sexual dimorphism of the phonatory organs. Speech therapy might thus be indicated as a vocal support for transgender women. Only few studies have examined the impact of perceived voice on the quality of life of transgender women.

The aim of this study is to prove the modulatory influence of sex hormones on serotonergic neurotransmission by determining the enzymatic processes involved in serotonin synthesis and degradation using positron emission tomography (PET) in humans in vivo with the radiotracers [11C]AMT and [11C]harmine.

This study will enroll female-to-male transgender youth who are and are not on a puberty blocker (gonadotropin-releasing hormone analogue) at baseline and 1 and 12 months after starting testosterone. The study will evaluate markers of cardiometabolic health including: insulin sensitivity, laboratory markers, vascular health, body composition, activity/fitness, mitochondrial function and the microbiome.

Observational survey study of transgender individuals who have undergone cosmetic neurotoxin and soft tissue filler for the purpose of influencing gender perception.

Majority of transgender and gender nonconforming people seeking medical care are in pubertal and reproductive age. Cross-sex hormones may compromise fertility especially when preceded by puberty blocking regimen. Our current understanding on reproductive needs of transgender persons is insufficient. The guidelines of Endocrine Society and the World Professional Association for Transgender Health prompt the health professionals to provide information on fertility risk and fertility preservation options before initiating hormonal treatment. Currently, no clear tools are available for healthcare professionals. Among several challenges for clinical care are a low clinical awareness, a lack of suitable psycho-educational instruments addressing fertility values that can be used to facilitate discussion between transgender persons and healthcare providers, a lack of established methods for fertility preservation in prepubertal youth, and a lack of long-term data regarding reproductive function, psychological and societal outcomes in this population. Likewise, current data are sparse regarding the experience of transgender and gender nonconforming people with fertility preservation. Our aim is to describe desires, attitudes and knowledge of transgender and gender nonconforming people regarding fertility preservation wishes and reproductive needs.

Genital feminine affirming surgery may be an important step for transgender women. Vaginoplasty consists in the creation of external female genitalia and an operational vaginal cavity, and thus responds to major functional and aesthetic issues. Different techniques are available: inversion of penile skin flap for creation of the vulva. The vaginal cavity may come from scrotal skin graft, sigmoid segment, small intestine, or peritoneal flap. Vaginoplasty has a major place in the the transgender woman pathway, but the specific evaluation of long-term sexuality has not been explored so far. Multicentric (Lyon, FR - Lille, FR - Limoges, FR), prospective, observational study Patients who underwent vaginoplasty or revision vaginoplasty. Main objective: To assess sexuality after sex reassignment surgery in transgender women.

The investigators hypothesize that masculinizing top surgery (e.g., mastectomy and chest masculinization) leads to an improvement in self-report chest dysphoria, gender dysphoria, and gender congruence in assigned-female-at-birth, transgender and non-binary youth and young adults. This is a prospective, observational study that will enroll assigned-female-at-birth, transmasculine spectrum individuals age 13 to 25 years old who are or are not undergoing top surgery. Participants will complete a set of standard of care questionnaires regarding their chest dysphoria (e.g., distress about the chest), gender dysphoria (e.g., distress about a gender identity that does not match assigned sex), and gender congruence (e.g., degree to which an individual feels they are living in their authentic appearance and gender identity). They will complete this same set of questionnaires either three months after their top surgery or three months after the initial set of surveys.

The number of adolescents engaging in a transidentity journey has been increasing rapidly over the last decade. However, the knowledge of the medical world concerning the specificities of these adolescents is still too little in France. The objective of this study is to refine the knowledge of the different health care providers who are brought to meet these adolescents. This research proposes to study more specifically the register of psychological vulnerabilities: to cite only a few examplesThese include disorders such as depression, anxiety disorders and eating disorders, all of which cause suffering and difficulties in everyday life. A better understanding of the presence or absence and the distribution of these different types of vulnerabilities among transgender adolescents would allow, among other things, to promote their their screening by health care providers. This better screening would allow doctors to physicians to offer targeted treatment for these disorders in parallel with the transition process. transition process.

This ultrahigh-field MRI study gives us the unique opportunity to measure changes in brain function and structure induced by long-term opposite-sex steroid hormone administration in transsexual subjects. Our aim is 1. to prove the influence of high-dose, long-term opposite-sex steroid hormone treatment on functional brain response in transsexuals. 2. to investigate the influence of hormone treatment on resting state functional connectivity and brain morphology. 3. to investigate differences between transsexuals and healthy control subjects in brain function and functional connectivity, brain morphology and structural connectivity. In this longitudinal study, transsexuals and healthy control subjects will undergo three 7 Tesla ultrahigh-field MRI scan sessions: 1. baseline (before hormone treatment), 2. after 4 weeks of treatment and 3. after 4 months of treatment.

The intent of this mixed methods study for transgender women after gender confirmation surgery is to characterize and subsequently create a validated screening questionnaire for postoperative urologic and pelvic floor symptoms. For individuals who seek gender-confirming treatment, about 13% undergo genital surgery for cosmetic purposes with or without gonadectomy, and this number is increasing. Patient satisfaction following surgery is high, particularly regarding sexual and cosmetic outcomes; however, unexpected negative functional outcomes such as bowel and bladder dysfunction and pelvic organ prolapse impact overall patient satisfaction. The available information suggests that 16-33% of patients experience incontinence postoperatively, with stress predominance, 32-47% experience abnormal voiding, and 24-66% experience overactive bladder symptoms. Outside of the typically assessed voiding symptoms, unique complaints of MTF postoperative patients include obstructive voiding symptoms due to urethral stenosis, persistent perimeatal erectile tissue, prostatic hypertrophy, and irritation from neovaginal tissue. Additionally, may of these patients develop symptomatic neovaginal prolapse, requiring re-suspension. We suggest that further clarification regarding MTF postoperative urologic and pelvic floor complaints can be achieved via a mixed methods approach. By using focus group interviews to create specific evaluative questions for this unique population, we can then prospectively assess patients undergoing surgery via a national multicenter sampling strategy. The goal of the study is to better understand the unique symptoms these women experience and create a validated, reliable screening questionnaire to monitor patients after surgery.
