A prospective, open-label, single-arm study to evaluate efficacy, safety and acceptability of pericoital oral contraception with levonorgestrel
This abstract summarizes a study to assess the efficacy, safety, and acceptability of oral levonorgestrel used pericoitally by women who have infrequent sex. The rates of pregnancy were higher than expected; further research is needed to assess whether this method of contraception could be recommended for women with low to moderate frequency of intercourse. Contraception. 2012;86(3):313.
