Erythropoietin, which stimulates red blood cell production, increases throughout pregnancy and reaches approximately 150 percent of their pregnancy levels at term. [24] The slight drop in hematocrit or hemoglobin is most pronounced at the end of the second trimester and slowly improves when reaching term.
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.
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] Prolactin is released into milk at amounts consistent ...
[1] [2] It is involved in lobuloalveolar maturation of the mammary glands during pregnancy and the induction and maintenance of lactation following parturition. [3] Hormones that control the secretion of prolactin from the pituitary gland include dopamine ("prolactin-inhibiting factor", or "PIF"), estradiol , progesterone , thyrotropin ...
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.
Estrogen, progesterone, and prolactin, as well as GH/IGF-1, produce their effects on breast development by modulating the local expression in breast tissue of an assortment of autocrine and paracrine growth factors, [25] [44] [62] [63] [64] including IGF-1, IGF-2, amphiregulin, [65] EGF, FGF, hepatocyte growth factor (HGF), [66] tumor necrosis factor α (TNF-α), tumor necrosis factor β (TNF ...
The onset of lactation (OL), also referred to as stage II lactogenesis or secretory activation, [1] [4] is one of the three stages of the milk production process. [1] OL is the stage when plentiful production of milk is initiated following the delivery of a full-term infant. [5] [6] It is stimulated by an abrupt withdrawal of progesterone and ...
