Lundberg

Daniel Lundberg PhD '24 and MIT postdoc Jimin Kim are the lead authors of the study, which appears in Nature Catalysis.

"Previous studies in this area have been relatively short-term, up to two years," explains Tommy Lundberg.

"In addition to the health aspects, our research contributes to increased knowledge about reasonable expectations of the masculinising and feminising effects of sex hormone treatment," says Tommy Lundberg.

Tommy Lundberg has been compensated for expert opinions on aspects related to skeletal muscle changes in transgender individuals and reimbursed for travelling to give lectures on the same topic.

"We saw that transgender men treated with testosterone increased their muscle volume by an average of 21 percent over six years, but also that the amount of abdominal fat increased by 70 percent," says Tommy Lundberg, docent at the Department of Laboratory Medicine, Karolinska Institutet.
