what is normal prolactin level in males
Hyperprolactinemia is defined as increased levels of serum prolactin. Normal prolactin levels are between 5-21 ng/mL. A prolactin level greater than 21 ng/mL is abnormally high (7). Hyperprolactinemia can be high due to normal physiological causes.Physiological or psychological stress can elevate prolactin in both men and women, but values rarely exceed 40 ng/mL.omen generally have higher levels of prolactin than men and also secrete more prolactin in response to physiological triggers than men (6). Strenuous exercise, sleep, and high-protein meals have also shown to increase prolactin levels.
