[22] [14] It is more specifically a derivative of norethisterone (17α-ethynyl-19-nortestosterone) and is a member of the gonane (18-methylestrane) subgroup of the 19-nortestosterone family of progestins. [23] [10] [24] [25] Gestrinone is the C18 methyl derivative of norgestrienone (17α-ethynyl-19-nor-δ 9,11 -testosterone) and the δ 9,11 analogue of levonorgestrel (17α-ethynyl-18-methyl-19-nortestosterone) and is also known as ethylnorgestrienone due to the fact that it is the C13β ethyl variant of norgestrienone.
