Summary

This trial will study the effects of estrogen and testosterone therapy on insulin sensitivity and beta cell function in transgender people.

What is being tested?
The study examines the effects of estrogen in transwomen on insulin sensitivity and immune response, as well as the impact of testosterone in transmen on glucose metabolism. It involves a Botnia Clamp procedure and temporary withdrawal from Gender Affirming Hormone Therapy.
What are the potential side effects?
Potential side effects may include changes in blood sugar levels due to hormone therapy adjustment. The Botnia Clamp might cause discomfort where it attaches to the body.
