Contraception
-
This paper reviews trials of the effectiveness of barrier contraception with and without spermicide, and discusses the advantages and disadvantages of using spermicides with barriers. There is very little evidence to allow comparison of the effectiveness of barriers with and without spermicide. ⋯ The lack of scientific data on this subject has prompted us to recommend research in specific areas. Until the findings of such research are available, the information which has emerged from this review suggests that the recommendations issued to users of barrier contraception should be brought up-to-date.
