Prolactin (also known as lactotropin and PRL) is a hormone that’s responsible for lactation, certain breast tissue development and contributes to hundreds of other bodily processes. Prolactin levels are normally low in people assigned male at birth (AMAB) and non-lactating and non-pregnant people.
Physiologic levels of prolactin in males enhance luteinizing hormone-receptors in Leydig cells, resulting in testosterone secretion, which leads to spermatogenesis. [20] Prolactin also stimulates proliferation of oligodendrocyte precursor cells.
The key role of prolactin in maternal physiology has traditionally biased neuroendocrinological studies towards its functions in the brain of females, whereas the actions of this hormone in the male brain have drawn less attention.
29 Νοε 2023 · Both males and females produce the hormone prolactin, but it is known for telling the body to make breast milk when someone is pregnant or breastfeeding. Production of prolactin takes place...
Abstract. Purpose of review: To review physiology of prolactin (PRL), cause and managment of hyperprolactinemia, and discuss evolving diverse roles of PRL in men's health. Recent findings: Hyperprolactinemia can be physiologically found after sexual activities, exercise, lactation, during pregnancy, and after stressful venipuncture.
24 Ιουλ 2023 · In females, too much prolactin leads to amenorrhea (absence of menstruation), which results from the prolactin inhibition of GnRH release. In males, however, prolactin level imbalances have different clinical implications. Too much prolactin in males results in headaches and decreased libido.
14 Δεκ 2023 · The normal range for prolactin in your blood is: Male/assigned male at birth: less than 20 nanograms per milliliter (ng/mL) Non-pregnant female/assigned female at birth: less than 25 ng/mL
