The invention relates to new 8α-oestra-1,3,5(10)-triene derivatives having the formula: STR1 in which R1 =H or a free, esterified or etherified hydroxy group; R2 =H or a free, esterified or etherified hydroxy group, with the proviso that at least one of the substituents R1 and R2 is different from H; R3 =alkyl (1-4 C) and R4 =O or (αX) (βY), in which X=H or aliphatic hydrocarbyl (1-4 C) and Y=a free, esterified or etherified hydroxy group and the enantiomers and racemic mixtures thereof, and also extends to processes for their preparation and to pharmaceutical compositions containing said new compounds.
