Mestranol
A synthetic oestrogen, the methyl ether of ethinylestradiol, into which the liver converts it: discovered in 1956 and in use since 1957, it was the oestrogen of the first combined contraceptive pill, together with the progestin noretynodrel. This family brings together the active ingredient.
Did you know?It was found almost by chance: the first batches of noretynodrel contained 1-2% of it as a manufacturing impurity, and when it was removed irregular bleeding appeared. So it was added back on purpose.
