Abstract. Husebye ES,

This case series adds to the growing literature demonstrating that RTX, administered in our patients with concomitant methylprednisolone, is safe and clinically effective in the treatment of active, moderate to severe and sight-threatening GO. Randomized controlled trials are now needed to confirm the efficacy of RTX for GO.

Many men in the UK might be receiving testosterone replacement therapy with neither clearly established indications nor robustly diagnosed hypogonadism. A national registry for men treated with testosterone and further evidence to improve current guidance (national and/or international) on the indications for testosterone replacement would be beneficial.
