Abstract
An attempt was made to ascertain whether the application of tantalum clips on Fallopian tubes is a reliable and reversible method of sterilization. Fifty rabbits were used in the study and the pregnancy rate following the application of the tantalum clip on each Fallopian tube was 29 per cent as compared with the 74 per cent pregnancy rate in the same rabbit colony during the same period of time. Following the removal of the tantalum clips from both Fallopian tubes, the pregnancy rate after 5 months of breeding was only 9 per cent. The reason for the high pregnancy rate in the rabbits with the tantalum clips and the low pregnancy rate following the removal of the tantalum clips is discussed. The view expressed is that more work needs to be done before this method is used as a reliable and reversible procedure for female sterilization.
