  • Method for reducing the reproductive function of mammals
    Patent number: 4001403
    Abstract: A method for altering the reproductive function of mammals by administering a pharmacologically effective amount of certain fluoroalkyl-substituted organosilicon compounds. As a means of illustration, one can orally or parenterally administer from 1.0 mg. to 100 mg. per kilogram of body weight (either as a single dose or as a daily dosage over a period of time) of an organosilicon compound of the formula ##STR1## thereby rendering the subject (either a male or female mammal) infertile.
