  2. 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]

  3. 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 ...

  4. Maternal physiological changes in pregnancy - Wikipedia

    The step lengthens as the pregnancy progresses, due to weight gain and changes in posture. On average, a woman's foot can grow by a half size or more during pregnancy. In addition, the increased body weight of pregnancy, fluid retention, and weight gain lowers the arches of the foot, further adding to the foot's length and width.

  5. 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.

  6. List of human hormones - Wikipedia

    en.wikipedia.org/wiki/List_of_human_hormones

    The following is a list of hormones found in Homo sapiens. Spelling is not uniform for many hormones. 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 ...

  7. Lactation - Wikipedia

    en.wikipedia.org/wiki/Lactation

    High levels of prolactin during pregnancy and breastfeeding also increase insulin resistance, increase growth factor levels (IGF-1) and modify lipid metabolism in preparation for breastfeeding. During lactation, prolactin is the main factor maintaining tight junctions of the ductal epithelium and regulating milk production through osmotic balance.

  8. Breast development - Wikipedia

    en.wikipedia.org/wiki/Breast_development

    In addition to their role in lobuloalveolar growth, prolactin and hPL act to increase the size of the nipple-areolar complex during pregnancy. [42] By the end of the fourth month of pregnancy, at which time lobuloalveolar maturation is complete, the breasts are fully prepared for lactation and breastfeeding. [30]

  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.
