It was the second progestogen to be marketed (intramuscular progesterone was introduced as Proluton in 1934) and was both the first orally active progestogen and the first progestin (orsynthetic progestogen) to be introduced.Although ethisterone has largely been superseded by newer drugs and is now little used, it continues to be available in some countries.Moreover, the 19-nortestosterone progestins, such as norethisterone, are derived from ethisterone and are widely used ashormonal contraceptives and for other indications.

The first orally active progestin, ethisterone (pregneninolone, 17α -ethynyltestosterone or 19-norandrostane), the 17α -ethynyl analog of testosterone, was synthesized in 1938 by Hans Herloff Inhoffen, Willy Logemann, Walter Hohlweg, and Arthur Serini at Schering AG in Berlin and marketed in Germany in 1939 as Proluton C and by Schering in the U. S. In 1945 as Pranone.
Ethisterone was also marketed in the U. S. From the 1950s into the 1960s under a variety of trade names by other pharmaceutical companies that had been members of the pre-World War II European hormone cartel (Ciba, Organon, Roussel).
