Which hormone is responsible for milk production?
Alveoli are the milk-secreting bunches of cells found within breast tissue. Prolactin also stimulates milk production after birth in conjunction with two other hormones, insulin and cortisol. Oxytocin, another hormone, aids in the let-down reflex, which allows milk to flow from the alveoli when the infant nurses.
The blockade is removed at the end of pregnancy by the expulsion of the placenta and the loss of its supply of hormones, as well as by the decline in hormone production by the ovaries, while sufficient estrogen remains in circulation to promote the secretion of prolactin by the pituitary gland and so favour lactation.
- The parathyroid hormone (PTH), secreted by the parathyroid glands, is responsible for regulating blood calcium levels; it is released whenever blood calcium levels are low. PTH increases blood calcium levels by stimulating osteoclasts, which break down bone to release calcium into the blood stream.
- The corpus luteum (Latin for "yellow body"; plural corpora lutea) is a temporary endocrine structure in female ovaries and is involved in the production of relatively high levels of progesterone, moderate levels of estradiol, inhibin A and small amounts of estrogen.
- ADH (continued) Increased blood volume prevents the release of ADH. As a result, the kidneys retain less water, which dilutes the urine and increases urine output. As fluid leaves the body, blood volume decreases and serum osmolality increases.
- Other Hormones Found in Breast Milk. Other hormones identified in human breast milk include gonadotropin-releasing hormone (GnRH), insulin, progesterone, estrogen, androgens, gastrin, adiponectin, resistin, and ghrelin.
- In the luteal phase, progesterone stimulates secretion by endometrial glands, and also promotes blood vessel growth. In the luteal phase following ovulation, estrogen and progesterone are secreted by the corpus luteum, which forms through the action of luteinizing hormone (LH).
- Thursday's Tip: Breastfeeding and the hormones of sexuality
- Estrogen: All women have low levels of estrogen for the first couple of months after giving birth.
- Oxytocin: The milk ejection reflex is triggered by the release of the hormone oxytocin.
- Prolactin: Prolactin levels increase when baby is breastfeeding or mother is expressing milk.
Once you expel your hormone-producing placenta, the estrogen and progesterone levels in your body suddenly drop. At the same time, the level of prolactin rises. This pituitary gland hormone signals your body to make lots of milk to nourish your baby.
- Foods that help increase your breast milk supply:
- Oatmeal. Oatmeal by itself is not the most flavorful food out there, but you can always spice it up by adding different fruits or blend in some cinnamon or honey.
- Brewer's Yeast.
- Intro. Lactation is the process of producing breast milk. For women who are pregnant or recently gave birth, lactation is normal. But it's also possible for women who have never been pregnant — and even men — to lactate.
- Mature milk contains water, fat, carbohydrates, protein, vitamins and minerals, amino acids, enzymes, and white cells. Over the course of a feeding, breast milk changes from foremilk, high in water and lactose, to hindmilk, high in fat and calories.
