Laparoscopy seems to be the ideal method of sterilization for women over 40. In a series of 60 cases over a 3 year period the author did not observe any complication or failure. Laparoscopy can very effectively be used to better evaluate the clinical situation prior to operation for tubal sterility. In such cases laparoscopy enables to check for the absence of peritoneal tuberculosis, and of pelvi-peritoneal adhesions. In a series of 26 patients, the author obtained, after operation, 11 pregnancies, 8 spontaneous abortions, 1 ectopic pregnancy, and 4 operative failures. The results obtained with other similar series are presented. Laparoscopy prior to operation for sterility can also give a better idea of the postoperative treatment to be followed.
