Definitive contraception or voluntary sterilization in men and women has become more and more common as a final and permanent contraceptive measure. This family planning method combines all advantages of contraceptives under the psychological prerequisites: independent and free decision, clear motivation regarding the renouncement of reproduction, agreement between the partners, balanced partnership and personality, detailed advice before the operation. These prognostic criteria are derived from the author's evaluation of 73 psychologico-psychiatric series of catamneses of the past five decades in international literature.
