A 3-methylene-4-androsten-17-one of formula I ##STR1## wherein R.sub.a represents a hydrogen atom or a saturated or unsaturated straight-chain or branched-chain, optionally substituted alkyl radical with 1-6 carbon atoms, in which R.sub.a is in the alpha- or beta-position, and R.sub.b represents a hydrogen atom, a hydroxyl or an --S(O).sub.n R.sub.c group, in which R.sub.c is a hydrogen atom or an alkyl or acyl group with 1-4 carbon atoms, n=0, 1 or 2, and X represents CH.sub.2, CHF, CHCl or CHBr, in which if R.sub.a is hydrogen and R.sub.b is hydroxyl or R.sub.a and R.sub.b each are hydrogen, X is not CH.sub.2. The new compounds of formula I are suitable for fertility control and for treatment of diseases which are promoted by estrogens.
