Preventing unnecessary pituitary magnetic resonance imaging: prolactin to  testosterone ratio predicts pituitary adenomas in male patients with mild hyperprolactinemia

Serum prolactin (PRL) levels are routinely obtained in men presenting with clinical hypogonadism or infertility with mild hyperprolactinemia, often prompting pituitary magnetic resonance imaging (pitMRI) to assess for adenoma. The utility of obtaining pitMRI in this population has not been adequately studied, and no society guidelines exist to inform this decision. We hypothesize that a combination of laboratory findings predicts positive pitMRI findings in patients with mild hyperprolactinemia and, given the high rate of negative pitMRIs among young men with mild hyperprolactinemia, sought to identify patients in whom pitMRI can safely be avoided.
