Expulsion can occur due to various reasons: - Uterine Contractions: Strong contractions, especially during menstruation, can push the IUD out. - Incorrect Insertion: If not correctly placed, the IUD may not stay in the optimal position. - Uterine Anomalies: Anatomical differences or conditions like fibroids can interfere with the placement of the IUD. - Age and Parity: Younger women and those who have not given birth are at a slightly higher risk of expulsion.
