Background: Bone marrow fat is a unique fat depot that is regulated independently of other fat depots. Estradiol is an important regulator of bone marrow fat. This is illustrated by an increase in marrow fat fraction after menopause and a decrease following estradiol replacement. We hypothesize that estradiol is the major sex steroid that regulates bone marrow fat not only in women, but also in men.Methods: This is an open-label partly randomized interve...

Objective: Visceral adipose tissue (VAT) and liver fat content are associated with insulin resistance and cardiovascular disease and show clear sex differences. Our objective is to determine the effect of estradiol and testosterone on VAT and liver fat content in trans women (assigned male at birth, identify as female) and trans men (assigned female at birth, identify as male).Design: Open-label partly randomized intervention study in 8 trans women and 1...

Background: Facial feminization or masculinization is particularly important in transpersons, both for self-image and social interaction. Females tend to have a smaller, rounder face, with more prominent cheeks and males tend to have a larger, more square face with frontal bossing. It is unknown whether cross-sex hormones can change these features. However, transgenders themselves often report facial changes due to hormone treatment. Therefore we aim to objectify if hormone tr...

Introduction: Testosterone is known to have an effect on hematocrit levels, with polycythemia as an unwanted side effect. An increase in hematocrit levels is also seen in transmen after starting cross-sex hormonal treatment (CHT) with testosterone. The aim of this study is to investigate the effect of cross-sex hormonal treatment with testosterone on hematocrit levels in the context of the safety aspects of this treatment. The prevalence, determinants and outcome of secondary ...
