  2. Prolactin - Wikipedia

    en.wikipedia.org/wiki/Prolactin

    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 ...

  3. Prolactin cell - Wikipedia

    en.wikipedia.org/wiki/Prolactin_cell

    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.

  4. Pregnancy hormones - Wikipedia

    en.wikipedia.org/wiki/Pregnancy_hormones

    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]

  5. Lactation - Wikipedia

    en.wikipedia.org/wiki/Lactation

    During lactation, prolactin is the main factor maintaining tight junctions of the ductal epithelium and regulating milk production through osmotic balance. Human placental lactogen (HPL) – from the second month of pregnancy, the placenta releases large amounts of HPL. This hormone is closely associated with prolactin and appears to be ...

  6. Maternal physiological changes in pregnancy - Wikipedia

    en.wikipedia.org/wiki/Maternal_physiological...

    The mother's body adapts by increasing parathyroid hormone, leading to an increase in calcium uptake within the gut as well as increased calcium reabsorption by the kidneys. Maternal total serum calcium decreases due to maternal hypoalbuminemia , but the ionized calcium levels are maintained.

  7. Parental brain - Wikipedia

    en.wikipedia.org/wiki/Parental_brain

    Prolactin is the hormone which mediates the increase in neurogenesis in SBZ. [31] [32] In animals, structures of the mother's brain change postpartum due to the increased interaction of the mother with the infant. [33] The volume of gray matter increases postpartum in the following brain regions: [33] bilateral hypothalamus; amygdala ...

  8. Endocrinology of reproduction - Wikipedia

    en.wikipedia.org/wiki/Endocrinology_of_reproduction

    The embryo upregulates hCG, drives growth of the cell, and upregulates P4 production driving development. hCG and P4 direct changes in the mother to enable successful pregnancy (see below) via upregulation of specific hormones that act to direct both endocrinological and biological changes within the mother for successful pregnancy.

  9. Human placental lactogen - Wikipedia

    en.wikipedia.org/wiki/Human_placental_lactogen

    However, the relative affinities of hPL and prolactin for the human prolactin receptor have yet to be published and the effects of hPL on normal human mammary epithelial tissue have not yet been investigated, and so a definitive role of hPL in human mammary gland development during pregnancy has not been established at present.
