Raised macroprolactin
WebbHyperprolactinemia (HPRL), which affects male sexual function and female reproduction, is a common endocrine disorder. Elevated PRL may be physiologic, pharmacologic, or pathologic. However, MPRL is quite common (ranging from 13–30%) and should be excluded before inappropriate investigations and therapy for HPRL are initiated. WebbThe term 'macroprolactinemia' is used when the concentration of macroprolactin exceeds 60% of the total serum prolactin concentration determined by polyethylene glycol …
