In 1969 the first and only First Presidency statement on birth control was released reemphasizing that it was "contrary to the teachings of the Church artificially to curtail or prevent the birth of children", though, for the first time there was a clarification that men should be considerate to "conserve" the "health and strength" of their wives when planning families since they carry the "greater responsibility" for bearing and rearing children.
