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sufficient serum estradiol (greater than 50 pg/mL), withdrawal bleeding should occur 2–7 days after the progestin is withdrawn, indicating that the patient's ...
DMPA can affect menstrual bleeding. After a year of use, 55% of women experience amenorrhea (missed periods); after two years, the rate rises to 68%. In the first months of use "irregular or unpredictable bleeding or spotting, or, rarely, heavy or continuous bleeding" was reported. [73]
The lack of menstruation usually begins shortly after beginning the medication and can take up to a year to resume after stopping its use. [41] Hormonal contraceptives that contain only progestogen, like the oral contraceptive Micronor, and especially higher-dose formulations, such as the injectable Depo-Provera, commonly induce this side effect.
Depot MPA (DMPA) and EC/MPA were developed by Upjohn in the 1960s. [12] [13] DMPA (brand name Depo-Provera) was introduced for use as a progestogen-only injectable contraceptive for the first time outside of the United States in 1969 and was subsequently approved for use in birth control in the United States in 1992.

Progesterone is used as part of hormone replacement therapy in people who have low progesterone levels, and for other reasons. For purposes of comparison with normal physiological circumstances, luteal phase levels of progesterone are 4 to 30 ng/mL, while follicular phase levels of progesterone are 0.02 to 0.9 ng/mL, menopausal levels are 0.03 to 0.3 ng/mL, and levels of progesterone in men ...
