PRL and polycystic ovary syndrome: Recently, a study in this region has reported hyperprolactinemia as a frequent (37%) observation among patients with PCOS.23 Furthermore, it has been reported that a pathological elevation of the circulating prolactin level may result from prolactin adenomas, hyperprolactinemic drugs, and macroprolactin or could be an idiopathic hyperprolactinemia.24,25 However, further etiological studies are needed to find out the specific reasons of hyperprolactinemia to minimize the burden of PCOS.
