PIP: The Asociacion Pro Bienestar de la Familia Ecuadoriana has employed since 1965 midwives to perform clinical services. This comparative study investigates 310 insertions of T Cu-200 done by physicians, and 297 insertions of the same IUD type done by midwives. Age and parity of acceptors were comparable in both groups. Insertions were executed by midwives with as much skill and knowledge as the doctors, and termination rates for medical reasons were almost similar in both groups. Several authors have confirmed the fact that experienced midwives can be successfully trained in performing IUD insertions.
