What this trial studies

This observational study aims to explore the relationship between the method of estrogen administration (transdermal vs. oral) and the associated cardiorenal risks in both cisgender and transgender women. Additionally, it will assess the impact of exogenous testosterone on cardiorenal risks in cisgender and transgender men. Participants will undergo a series of tests, including blood draws and non-invasive monitoring, during a 4.5-hour lab session while fasting. The study seeks to provide insights into how hormone therapy affects cardiovascular and renal health across different gender identities.

Who should consider this trial

Good fit: Ideal candidates include individuals aged 18 to 90 who are currently taking hormones, either estrogen, progesterone, or testosterone.

Not a fit: Patients with cardiovascular or cerebrovascular diseases, significant hypertension, diabetes, or those who are current smokers may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance understanding of hormone therapy's safety and risks, leading to better management strategies for patients undergoing such treatments.

How similar studies have performed: While there have been studies on hormone therapy, this specific investigation into the cardiorenal risks associated with different hormone administration routes is relatively novel.
