The anterior pituitary produces six hormones: growth hormone, adrenocorticotropin (corticotropin), thyroid stimulating hormone (thyrotropin), prolactin, follicle stimulating hormone, and lutenizing hormone.
Bromocriptine-Also known as Parlodel, it is a dopamine receptor agonist used to treat galactorrhea by reducing levels of the hormone prolactin and is also used to treat Parkinson's disease.
During pregnancy prolactin helps to increase breast mass but does not cause lactation because it is inhibited by the hormone progesterone, which is made by the placenta.
Other tests may include a thyroid level; sperm count; prolactin level (milk hormone); blood tests for anemia, chemistries, and iron; and genetic analysis.
Prolactin levels rise and fall in direct proportion to the frequency, intensity, and duration of nipple stimulation from the infant's suckling.
If a mother does not breastfeed, prolactin levels usually reach the levels of the nonpregnant state by seven days postpartum.
There are a number of causes of hypogonadism, including stress, elevated prolactin levels, and several genetic disorders.
After milk "comes in" or rapidly increases in volume, lactation is no longer driven by the hormone prolactin.
During the first week after birth, prolactin levels in breastfeeding women fall about 50 percent.
The act of breastfeeding itself causes a surge of prolactin.
