Abstract

There are provided 13-alkyl-11beta-phenyl-gonanes of formula I ##STR1## wherein Z is an oxygen atom or N--OH; PA0 R.sup.2 is alpha- or beta-position methyl or ethyl; PA0 R.sup.1 is selected from heteroaryl radicals, cycloalkyl radicals, cycloalkenyl radicals, aryl radicals, alkenyl radicals, and alkyl radicals where R.sup.2 is in the alpha-position and an ethyl radical where R.sup.2 is in the beta-position; and PA0 R.sup.3 and R.sup.4 are selected from one of two different groups of substituent pairs, the group from which the selection is made being determined by the position of R.sup.2.
