The test is performed by administering a progestogen, such as progesterone either as an intramuscular injection or oral medroxyprogesterone acetate (Provera). If the patient has sufficient serum estradiol (greater than 50 pg/mL), withdrawal bleeding should occur 2–7 days after the progestin is withdrawn, indicating that the patient's ...
Prolactin has a wide variety of effects. It stimulates the mammary glands to produce milk (): increased serum concentrations of prolactin during pregnancy cause enlargement of the mammary glands and prepare for milk production, which normally starts when levels of progesterone fall by the end of pregnancy and a suckling stimulus is present.
