What is the expulsion rate range for immediate post-placental IUDs?

The expulsion rate for immediate post-placental intrauterine devices (IUDs) typically falls within the range of 10-27%. Immediate post-placental insertion of IUDs is a common practice due to the advantages of convenience and the reduced risks of unintended pregnancy shortly after childbirth. While this method is effective, data show that there is a notable risk of expulsion, with the range indicating that between 10% to 27% of IUDs may be expelled within the first few weeks following insertion. This phenomenon can be attributed to several factors, including the size of the uterus immediately after delivery, the type of IUD used, and the overall uterine tone. Understanding this expulsion rate is essential for counseling patients on the usage of IUDs after childbirth and for effective family planning strategies.
