The magnitude that prolactin is elevated can be used as an indicator of the etiology of the hyperprolactinemia diagnosis. Prolactin levels over 250 ng/mL may suggest prolactinoma. Prolactin levels less than 100 ng/mL may suggest drug-induced hyperprolactinemia, macroprolactinemia, nonfunctioning pituitary adenomas, or systemic disorders.
Prolactin levels peak during REM sleep and in the early morning. Many mammals experience a seasonal cycle. [38] During pregnancy, high circulating concentrations of estrogen and progesterone increase prolactin levels by 10- to 20-fold. Estrogen and progesterone inhibit the stimulatory effects of prolactin on milk production.
Endogenous signals such as an increase in estrogen compared to a decrease in progesterone, causes an increase in the levels of prolactin, the “lactating hormone,” in the bloodstream. Furthermore, exogenous cues from infants such as suckling induces this mechanism. [ 18 ]
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.
Ramelteon has been found to slightly increase prolactin levels in women (+34% vs. –4% with placebo) but not in men and to decrease free testosterone levels (by 3–6% in younger men and by 13–18% in older men). [3] [20] [21] Ramelteon has not been shown to produce dependence and has shown no potential for abuse. [3]
Estrogen and progesterone cause the secretion of high levels of prolactin from the anterior pituitary, [32] [33] which reach levels as high as 20 times greater than normal menstrual cycle levels. [31] IGF-1 and IGF-2 levels also increase dramatically during pregnancy, due to secretion of placental growth hormone (PGH). [34]
During pregnancy, the production of prolactin by the mother increases steadily, starting at 6–8 weeks of gestation and continuing until the end of the pregnancy. [32] Prolactin levels in the human fetal circulation see a gradual increase from around 30 weeks of gestation until birth. [32]
In this video, a mother uses breast compression during a feed to increase the flow of milk (1 minute, 37 seconds) Using a breast pump can maintain and improve milk supply if the baby is unable to nurse effectively. Attempts to increase milk supply should begin promptly as the longer low supply continues, the more difficult it is to reverse. [2]
