MD‡Journal of Psychiatric Practice: March 2012 - Volume 18 - Issue 2 - p 126–129 doi: 10.1097/01.pra.0000413279.95843.b5 Clinical Case Discussion Abstract Author Information Hyperprolactinemia is a common consequence of treatment with an antipsychotic medication. It can result in hypogonadism due to the inhibitory effect of elevated prolactin levels on the hypothalamic-pituitary-gonadal hormonal axis. We present a case of hypogonadism secondary to hyperprolactinemia in a patient taking antipsychotic medication, with radiological evidence of a pituitary microadenoma. The relevance and investigation of hyperprolactinemia in patients being treated with antipsychotic medications are discussed.
