In women, normal prolactin levels average to about 13 ng/mL, while in men, they average 5 ng/mL. The upper normal limit of serum prolactin is typically between 15 to 25 ng/mL for both genders. [ 1 ] Levels exceeding this range indicate hyperprolactinemia.
General guidelines for diagnosing prolactin excess (hyperprolactinemia) define the upper threshold of normal prolactin at 25 μg/L for women and 20 μg/L for men. [59] Similarly, guidelines for diagnosing prolactin deficiency (hypoprolactinemia) are defined as prolactin levels below 3 μg/L in women [72] [73] and 5 μg/L in men.
The most common complex found in blood consists of prolactin and immunoglobulin G (IgG). [1] While the free prolactin hormone is active, prolactin in the macroprolactin complex does not have any biological activity in the body and is considered benign. [2] However, macroprolactin is detected by all Laboratory tests that measure prolactin in ...

Prolactin levels significantly decrease with age in women, and slightly increase with age in men. [3] The average prolactin level in men is between 10 and 11 ng / mL [4] [3]. The average prolacin level in women between the ages of 15 and 25 is approximately 20 ng / mL, and steadily decreases with age; women 55 and older have average prolactin ...

For comparison, normal prolactin levels in women are less than 20 ng/mL, prolactin levels peak at 100 to 300 ng/mL at parturition in pregnant women, and in lactating women, prolactin levels have been found to be 90 ng/mL at 10 days postpartum and 44 ng/mL at 180 days postpartum. [77] [78]
For instance, prolactin and other hormones related to prolactin levels may be associated with anorgasmia. Loss of sensation. Research suggests it’s normal to lose some level of sensitivity with age.
