Prolactin (PRL), also known as lactotropin and mammotropin, is a protein best known for its role in enabling mammals to produce milk. It is influential in over 300 separate processes in various vertebrates, including humans. [5] Prolactin is secreted from the pituitary gland in response to eating, mating, estrogen treatment, ovulation and ...
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.
Hypoprolactinemia is associated with ovarian dysfunction in women, [3] [4] and, in men, metabolic syndrome, [5] anxiety symptoms, [5] arteriogenic erectile dysfunction, [6] premature ejaculation, [5] oligozoospermia (low concentration of sperm in semen), asthenospermia (reduced sperm motility), hypofunction of seminal vesicles, and hypoandrogenism.

Hyperprolactinemia, characterized by abnormally high levels of prolactin, may cause galactorrhea (production and spontaneous flow of breast milk), infertility, and menstrual disruptions in women. In men, it can lead to hypogonadism, infertility and erectile dysfunction. Prolactin is crucial for milk production during pregnancy and lactation.
The following is a list of hormones found in Humans. Spelling is not uniform for many hormones. For example, current North American and international usage uses [citation needed] estrogen and gonadotropin, while British usage retains the Greek digraph in oestrogen and favours the earlier spelling gonadotrophin.
Male lactation was of some interest to Alexander von Humboldt, who reports in Voyage aux régions équinoxiales du Nouveau Continent about a citizen of the Venezuelan village of Arenas (close to Cumana) who allegedly nurtured his son for three months when his wife was ill, [1] as well as Charles Darwin, who commented on it in The Descent of Man, and Selection in Relation to Sex (1871):
Suzannah Weiss, a certified sex educator and resident sexologist for Frolicme.com, notes that after orgasm your body also releases the hormone prolactin, which can help induce rapid eye movement ...
Prolactin, a major hormone of the HPP axis.. The hypothalamic–pituitary–prolactin axis (HPP axis), also known as the hypothalamic–pituitary–mammary axis or hypothalamic–pituitary–breast axis, is a hypothalamic–pituitary axis which includes the secretion of prolactin (PRL; luteotropin) from the lactotrophs of the pituitary gland into the circulation and the subsequent action of ...
