Results of experience with a low-oestrogen combined contraceptive in 1,085 women showed that a dosage of less than 50 μg is compatible with satisfactory cycle control and efficacy. The preparation used in the trial, which contained 0·5 mg dl-norgestrel and 0·03 mg ethinyloestradiol, proved acceptable to most of the women.
