He first presented to endocrinology services having stopped finasteride after 20 years, reporting new onset reduced libido, penile shrinkage, fatigue, new food intolerances and agitated depression which was the predominant symptom in this case. He described the emergence of gynaecomastia, which was evident on examination, as well as muscle atrophy.
