  • Patent number: 4098905
    Abstract: The ability of a male to impregnate a female is reversibly effected by administering to the male, preferably daily in pill form, an effective amount of a trihalomethyl-containing lower alkanol, aldehyde, acid, amine, ether, or the like, or a derivative such as an amide or salt which liberates such compound in the body. The length of time needed for the male to regain his fertility depends upon the dosage of active material, preferably trifluoroethanol.
