Sterilization is a final, definitive form of preventing conception for family planning. The 1966-1970 statistics for the Hamburg-Altona Frauenklinik show an increase in the number of sterilizations versus abortions; the number of expert evaluations approving surgical sterilization also show a statistical increase. Apart from the legal or ethical questions, medical problems such as varicosities and intolerance to ovulation suppressants as well as multiparity are indications for such a procedure. There 3 main techniques: sterilization by the abdominal approach (e.g., tubal ligation); by the vaginal approach (e.g., with partial resection after Labhardt and Pomeroy's method); and postpartum sterilization. The third method can be further distinguished as following a cesarean section or after a successful vaginal delivery. The method of choice, with the fewest complications, is the postpartum one after normal vaginal delivery using a subumbilical incision with subserous tubal resection after Labhardt. This procedure is technically simple and is virtually completely without postoperative complications.
