The phrase
"prolactin secretion" refers to the release of a hormone called prolactin. Prolactin is produced by the pituitary gland in the brain and plays a crucial role in various functions related to reproduction and lactation. When prolactin is secreted, it affects the breast tissues and stimulates milk production in women after childbirth. It is also involved in regulating the menstrual cycle and supporting fertility.
Full definition
Medications used typically include something to
disrupt prolactin secretion (either cabergoline or bromocriptine) in combination with a prostaglandin (a hormone to induce uterine contractions and directly destroy the corpus luteum).
However, fluoxetine also has been reported to cause galactorrhea in nonpuerperal humans.15 The most likely explanation is that serotonin inhibits dopamine centrally, thereby increasing
prolactin secretion.15 It is unclear how these two somewhat opposing effects might influence milk production or composition.
In the first few months after giving birth,
prolactin secretion is at its highest.
