New study results in more precise language in the federally mandated warning about this possibility. (Article from the USA)
Women who choose to use an intrauterine device, or IUD, for birth control should be aware of the very small possibility that the device could puncture their uterus. They should know how to recognize that circumstance if it occurs, according to a new study published in The Lancet.
The U.S. Food and Drug Administration mandated the study to evaluate women's risks when an IUD is placed in the year after giving birth and when an IUD is placed during the period that a woman is breastfeeding a baby. These results were compared, respectively, with non-postpartum insertions and insertions in non-breastfeeding individuals, explained UW Medicine’s Dr. Susan Reed, the study’s lead author.
Across the study cohort of 327,000 women, the percentage of perforation cases diagnosed within five years of IUD insertion was 0.6 %, the study concluded.
- The risk of perforation increased by nearly seven times if it was inserted between four days and six weeks postpartum, and increased by about one-third if inserted during the span of breastfeeding.
- The risk of an IUD-related perforation was relatively lower when inserted in women who were more than a year beyond delivery, in women who had never had a baby, and when the insertion occurred at delivery.
