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.
In women, prolactin is the hormone that regulates milk production. High prolactin levels can lead to a bunch of issues like infertility, intimate problems and bone loss, as well as breast pain and ...
Hyperprolactinemia occurs more commonly in women. The prevalence of hyperprolactinemia ranges from 0.4% in an unselected normal adult population (10,000 normal Japanese adults working at a single factory) to as high as 9 to 17% in women with reproductive disorders.
A prolactin cell (also known as a lactotropic cell, epsilon acidophil, lactotrope, lactotroph, mammatroph, mammotroph) is a cell in the anterior pituitary which produces prolactin (a peptide hormone) in response to hormonal signals including dopamine (which is inhibitory), thyrotropin-releasing hormone and estrogen (especially during pregnancy), which are stimulatory.
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 ...
