[citation needed] Norethisterone was the first highly active oral progestogen to be synthesized, and was preceded (as a progestogen) by progesterone (1934), ethisterone (1938), 19-norprogesterone (1944), and 17α-methylprogesterone (1949) as well as by nandrolone (1950), whereas noretynodrel (1952) and norethandrolone (1953) followed the ...

Progestogens such as norethisterone acetate and medroxyprogesterone acetate may be used to artificially induce progesterone-associated breakthrough bleeding. [27] The progestogen challenge test or progestogen withdrawal test is used to diagnose amenorrhea. Due to the availability of assays to measure estrogen levels, it is now rarely used.
Extended cycle use of COCPs may also be called menstrual suppression, [2] although other hormonal medications or medication delivery systems (hormonal intrauterine devices—IUDs) may also be used to suppress menses.
