Abstract
Ten ectopic pregnancies subsequent to tubal sterilization were histologically evaluated. In 7 of the 10 cases, the sites for the ectopic implantation appeared to be related to the presence of a distal remaining tubal segment that had a tuboperitoneal fistula on the medial side. As against a currently held opinion that the ectopic implantation occurs secondary to a relative disparity in the size of the sperm, the fertilized ovum, and the proximal tuboperitoneal fistula, the implantations could be influenced by probable fluid movements within the remaining tubal segments.
