[Intra-uterine contraceptive devices in nulliparous women: a retrospective study].


 The insertion of intrauterine devices (IUDs) in nulliparous women is a controversial subject, with no unanimous opinion on whether or not to use this method. A study was undertaken to analyze retrospectively the complications of the TCu-200 IUD in nulliparous women compared to complications encountered in multiparous women using the same device. In 1982 and 1983, the Family Planning and Human Reproduction Clinic of the UFMG Medical School in Belo Horizonte, Brazil, inserted 114 IUDs in nulliparas. The principle characteristics of the study group were a low socioeconomic condition, regularity of menstrual flow, and absence of vaginal infection at the time of examination. The choice of method was the spontaneous decision of the women. It was noted that nulliparas requested IUD insertion after previous unsatisfactory experience with other contraceptive methods. 56% of the group were single and 38% married. For comparison, 300 records of multiparous TCU-200 IUD users were studied retrospectively. All insertions were made by the same clinic. The racial, social, and economical characteristics were typical of the users of any free family planning service. Among early complications, pain and lipothymia were encountered at an elevated incidence in nulliparous women when compared to multiparas (p0.01). Among late complications, the appearance of vaginal discharge and metrorrhagia were significant when compared to multiparas (p0.05). Pelvic infection and dysmenorrhea, although more frequent in nulliparas, were not statistically significant. The authors concluded that the IUD should not be used as the contraceptive method of 1st choice in nulliparous women, using it only in exceptional situations.
