Powerful MRI scans aim to reveal hidden brain changes in testicular cancer survivors

This study uses a very powerful 7 Tesla MRI scanner to take detailed pictures of the brain in testicular cancer patients who have low testosterone (hypogonadism) and are receiving testosterone replacement therapy. The goal is to see if this advanced imaging can detect changes in brain structure and function that may be linked to low testosterone. Ten adult men who have had testicular cancer treatment and been on testosterone therapy for at least 6 months will participate. This research does not test a new treatment but aims to better understand how low testosterone affects the brain.
