Other Research



In recent years, we have welcomed an increase in the number of research projects and publications related to transgender and gender diverse health from groups around the United States and the world. Nonetheless, there remain many gaps in knowledge related to the health of this community:

  • long-term effects of gender-affirming hormone therapy in adolescents all the way through older adulthood,
  • patient-reported outcomes of gender-affirming surgery,
  • and improving best practices for health care access and delivery. 

Our researcher team includes faculty, staff and learners at University of Colorado School of Medicine, Children’s Hospital of Colorado, UCHealth and Rocky Mountain Regional Veterans Affairs Medical Center. In collaboration with our Community Advisory Board, we strive to conduct research projects (approved by our Colorado Multiple Institutional Review Board) that are informed by the local transgender and gender diverse community and have beneficial implications for improved health and outcomes in our patient population.

Local, national and international organizations have funded projects, putting Colorado on the map as a leader in transgender and gender diverse-related research.

MY TRANSGENDER BRAIN STUDY (MyT “MIGHTY” BRAIN)

Researchers at the University of Colorado School of Medicine want to learn more about how gender-affirming hormone therapy (testosterone) affects thinking and behavior in transgender males and transmasculine non-binary individuals. The goal of this study is to contribute to the existing medical knowledge and to help clinicians better understand and treat transgender individuals and the LGBTQ+ community. 

You may be eligible if you are: 

  • Between the ages of 18 and 38 years 
  • Assigned female at birth but identify as male or masculine 
  • Right-handed 
  • Not currently using Gender Affirming Hormone Therapy (testosterone) 
  • Do not have any serious, untreated medical or mental health issues 

Study participants will: 

  • Participate in 3 study visits over the course of 4-5 months 
  • Complete interviews, questionnaires, and memory tests 
  • Have their blood drawn and tested for drugs via urine drug screen 
  • Undergo two magnetic resonance imaging scans (MRIs) 

*Compensation for time and parking vouchers will be provided.

Novel Evaluations of Aging and Gender-Affirming Hormone Therapy on Vascular Endothelial Function and Metabolic Profiles in Transgender Women Compared to Age Group-Matched Cisgender AdultsWe are studying the effects of taking long-term feminizing gender-affirming hormone therapy (>1 year) on the blood vessels and metabolic health in younger (18-40 years old) and older (50-75 years old) transgender women who have not had orchiectomy.

The Effects of Orchiectomy and Age on Vascular and Metabolic Health in Older versus Younger Transgender WomenThe global aim of this study is to characterize cardiometabolic risk (measured by vascular, metabolic and biochemical factors—which have not been extensively studied prospectively) in trans women before and after orchiectomy (baseline, 1 month, 6 months, and 12 months) and whether age group (“older” [aged 45 years and older] vs. “younger” [aged 18-44 years]) modulates these factors. The effect of orchiectomy on CVD risk among trans women is unknown, but orchiectomy may change blood vessel function and metabolic health. We will examine blood vessel function and metabolic profiles of trans women before and at several timepoints after orchiectomy to identify age-related differences in cardiovascular disease (CVD) risk factors. This knowledge may lead to new approaches to prevent CVD in trans women as well as all people regardless of gender identity.Mary Mancuso, MA

Prospective Evaluation of Transgender Patient’s Perception on Gender-Affirming TerminologyGender-affirming surgery is a relatively new and rapidly-growing domain in plastic surgery. The language used to describe gender-affirming surgery has been influenced not only by scientific terminology, but also by cultural influences. The objective of the study was to investigate the terminology deemed to be professional and unprofessional as determined by the transgender community.Leela Mundra, MD

Our Community, Our Health Database: Characterizing Health Outcomes for Transgender and Gender Diverse Patients of UCHealth Integrated Transgender Program (UCH ITP) and Children’s Hospital Colorado TRUE Center for Gender Diversity (TRUE)The overarching objective is to focus on the investigation of the data quality in the CHCO OMOP database and the Health Data Compass (HDC) UCHealth OMOP database for the purposes of transgender and gender diverse (TGD) patient research which include obtaining and validating data. Our goal is to create a research database, to be called “Our Community, Our Health (OCOH).” Data for this database will be comprised of data collected during routine clinical care, commonly referred to as secondary data, from patients seen at UCHealth and Children’s Hospital Colorado (CHCO). Both CHCO and UCHealth are leaders in TGD care. UCHealth has the Integrated Transgender Program (UCHealth ITP) and CHCO has the TRUE (Trust, Respect, Understand, Emerge) Center for Gender Diversity. The target population for the OCOH research database will be all UCHealth and CHCO patients receiving care for gender dysphoria and associated conditions.Danielle Kline, MS
