      Abstract

      A flexible polyethylene plastic loop for intrauterine contraception which can be inserted without dilation of the cervix gave an over-all pregnancy rate of 2.2 per 100 women per year, 4.8 for the smaller and 1.0 for the larger size.
      Menstrual and intermenstrual bleeding were increased during the early months.
      Expulsions during the first 12 months of use were 21.0 per cent for the smaller and 7.7 per cent for the larger size. Removals for reasons related to the method during the same period were 15.2 per cent for the smaller and 14.4 per cent for the larger size. A linear polyethylene suture extending into the vagina makes it easy to determine whether the loop is still in place.
      When the loop was removed from 32 women who wanted a child, more than half became pregnant in 3 months, and none took longer than 9 months. All the children were normal.
      No increase in the proportion having pelvic inflammatory disease was noted. The rates found were 0.4 and 0.7 per 100 women years.
      Endometrial biopsies and Papanicolaou smears gave no evidence that the method induced carcinoma.
      The intrauterine loop appears to be an acceptable, safe, inexpensive, and effective method of contraception.
