    • The invention concerns 14,17-C2-bridged steroids of general formula (I), wherein: R represents an oxygen atom, the hydroxy amino group or two hydrogen atoms; R represents either a hydrogen, fluorine, chlorine or bromine atom or a C1-C4 alkyl group at the alpha or beta position, R and R then representing hydrogen atoms; or alternatively, R represents a hydrogen, fluorine, chlorine or bromine atom or a C1-C4 alkyl group, R and R then representing a common additional bond; R represents a C1-C4 alkyl group at the alpha or beta position, R and R then representing hydrogen atoms; or alternatively R and R together represent a methylene group at the alpha or beta position and R represents a hydrogen atom; or R and R together represent an ethylene or methylene group and R represents a hydrogen atom; R and R each represent a hydrogen atom or a common bond; R and R each represent a hydrogen atom or a common bond; R represents a methyl or ethyl group; R represents a hydrogen atom or a C1-C3 alkyl group; R and R independently of one another represent a hydrogen atom, a C1-C3 alkyl group, or a C2-C4 alkenyl group, or together represent a C1-C3 alkylidene group; R and R represent a common bond and R represents a hydrogen atom or a C1-C3 alkyl group, or alternatively R and R together represent a ring of the partial formula (i) shown, in which n = 1 and 2 and X represents a methylene group or an oxygen atom; and R represents a hydrogen atom; R17 represents a hydrogen atom or a C1-C3 alkyl group; R17 represents a hydrogen atom, a C1-C3 alkyl group or a C2-C4 alkenyl group; R17 and R17 each represent a hydrogen atom or a common bond; R represents a hydrogen atom or a C1-C3 alkyl group; and R represents a hydrogen atom, C1-C3 alkyl group or hydroxy group. The claimed compounds do not include 14,17-ethano-19-norpregn-4-en-3,20-dione. The novel compounds, unlike the one disclaimed, show a high level of gestagenic activity even after peroral administration and are suitable for use in the production of medicaments.
