Abstract
A study was undertaken to look at the clinical behavior of the Dalkon Shield, the Lippes Loop D and the TCu-200 inserted by physicians and midwives. Differences among the three devices were not statistically significant, although lower expulsion rates and higher pregnancy rates were reported for the Dalkon Shield. No differences were observed between insertions performed by physicians and those performed by midwives; this emphasizes the efficiency of using paramedical personnel in the field of intrauterine contraception.
