ResumoNeo Sampoon a foaming vaginal tablet containing 60 mg of the spermicide menfegol and the Collatex sponge (now marketed in the U.S. as the Today spongs) a dome-shaped polyurethane device that contains 1 g of nonoxynol-9 were compared in terms of effectiveness safety and acceptability. Both methods were new to the Maribor General Hospital Yugoslavia where the trial was conducted among 450 volunteers randomly assigned to 1 of 2 methods. At 12 months the life table pregnancy rate/100 women for the Neo Sampoon group was 12.8 compared with a rate of 10.4 among the sponge users (P.10). After pregnancy the 2nd most frequent reason for termination was discomfort with a 12 month termination rate due to this cause of 6.9/100 women in the Neo Sampoon group and 6.2 in the sponge group. Although fewer than 1/4 of the volunteers had any experience with barrier methods before this trial the life table continuation rate was high in both groups with more than 70% using their assigned method for the full 12 months. Also at the conclusion of the study 41% of the volunteers chose another barrier contraceptive method. Although the sponge effectiveness and Neo Sampoon are not comparable to that of the pill or IUD both vaginal methods appear to be safe and acceptable additions to the wide range of contraceptive choices.
