We present the case of a 16-year-old male who presented reporting a 6-month history of lowered mood, fatigue, anhedonia, disturbed sleep and heightened anxiety. On further questioning he reported restricted eating and weightlifting for at least 1 h on a daily basis. Investigations revealed findings compatible with secondary hypogonadism. The potential causes of secondary hypogonadism including structural lesions, muscle dysmorphia and use of illicit anabolic steroids are discussed.
