All esters are derivatives of cycloalkycarboxylic acids. Some of the esters possess α- , β -and/or & - substitution in the ester side-chain. The work was undertaken in order to evaluate long-acting male antifertility effect of such esters. Most of the compounds, especially compound No.1, were found to be active. Compound No.1 is presently under clinical studies.
