What two hormones target the mammary glands?
The two hormones that target the mammary glands are prolactin and oxytocin. Prolactin is responsible for milk production, while oxytocin triggers the release of milk from the glands during breastfeeding.
What are the functions of prolactine?
In females, prolactin tell the breasts to start producing milk (but it is another hormone, oxytocin, that actually causes the milk to be excreted). In both sexes, prolactin also inhibits LH and FSH release, which inhibit estrogen/progesterone secretion and ovulation in females, and testosterone secretion and sperm production in males. Overproduction of prolactin (like from a tumor or a dopamine antagonist) can cause infertility and decreased sex drive in both sexes.

What produces both prolactin and growth hormone in the human body?
The pituitary gland produces both prolactin and growth hormone in the human body.
Can a virgin breastfeed?
A virgin can breastfeed. The hormones that trigger breastmilk to be produced are Prolactin and oxytocin. These are are pituitary (not ovarian) hormones. Because of this a woman who's never been pregnant or has had a hysterectomy may be able to lactate. Both are produced in response to nipple stimulation by massage, breast pump, and baby's nursing. This can be assisted by taking lactation-inducing drugs called, galactogogues. This includes drugs like Domperidone and herbal remedies like fenugreek.
What is hormonal control in milk synthesis in cows?
There are two hormones involved in the synthesis and release of milk: prolactin and oxytocin. Both are produced in a pea-sized gland attached to the base of the brain called the pituitary gland, and carried to the breasts by the blood. Prolactin is produced by the anterior(front part) of the pituitary gland. It stimulates the cells in the breasts to synthesise milk. Prolactin synthesis is stimulated by several minutes of the infant sucking at the breast. Oxytocin is synthesised by the posterior (rear part) of the pitutary gland. It stimulates the release of the milk from the breast (also called milk 'let down'). Oxytocin production is also stimulated by suckling at the breast.

Nursing interventions associated with hydrocephalus?
Sometimes no intervention is necessary, but a shunt, medication, or both is usually prescribed.
Why does cirrhosis causes hyperprolactinemia?
because prolactin is metabolized by liver and kidney both;;so in case of cirhosis or kidney failure prolactin goes sky high.
What is normal range of prolactin hormone?
The normal range for prolactin is 4-30 ng/ml in females and 4-23 ng/mL in males. However, they also vary by age and time of day and so should be interpreted in the complete clinical scenario. == == Simply put, prolactin is a hormone secreted by the body that causes lactation, or the "let down" reflex in women who are nursing so that milk is available to the baby. Prolactin, like other hormones, also has other effects on the body, but lactation is the primary effect. While this is a female response, both male and female have prolactin in their bodies.
Does oxytocin prevents premature births?
No oxytocin is used to stimulate labor. In humans, oxytocin stimulates milk let down during lactation, uterine contraction during birth and is released during sexual orgasm in both men and women.
Which hormone is most similar to oxytocin in chemical structure?
Vasopressin is the hormone most similar to oxytocin in chemical structure. Both hormones are nonapeptides, containing nine amino acids, and differ by only two amino acids in their structure.
What gland releases prolactin?
The pituitary gland releases prolactin. It plays a key role in stimulating milk production in women after childbirth, as well as regulating various reproductive processes in both men and women.
