Prevalence of hyperprolactinemia and abnormal magnetic resonance imaging findings in a population with infertility.

Hyperprolactinemia is rare among asymptomatic patients with infertility. Its prevalence and the mean PRL levels did not differ with [1] the infertility diagnosis, [2] the presence or absence of menstrual irregularities, or [3] the severity of menstrual dysregulation. Abnormal magnetic resonance imaging findings, though, are not uncommon among women with hyperprolactinemia despite the lack of symptoms and the mild PRL elevations.
