Hypogonadism Clinical Trial
Official title:
A Pilot Study of 7 Tesla MRI Neuroimaging in Testicular Cancer Patients With Hypogonadism and Androgen Replacement Therapy
This study evaluates 7 Tesla (T) magnetic resonance imaging (MRI) in observing changes in the brain (neuroimaging) in testicular cancer patients who have decreased testosterone (hypogonadism) and are on testosterone (androgen) replacement therapy. Symptoms of hypogonadism can include fatigue, weakness, loss of libido, depression, poor concentration and erectile dysfunction. Some patients experience mental changes after diagnosis and treatment. There is some evidence that hypogonadism produces structural changes in the brain. The 7T MRI uses radio waves and a very powerful magnet linked to a computer to create detailed pictures of areas inside the body. This study may help researchers learn if 7T MRI can produce better images to assess the changes in the brain structure of testicular patients with hypogonadism and on androgen replacement therapy (ART).
