Post-cesarean section insertion of intrauterine devices.

Among 52 women who delivered by cesarean section in a medical center in Beijing, China and had either a Delta Loop or Delta T intrauterine device (IUD) inserted manually through the incision wound, the expulsion rates were significantly lower than among a comparable group of 147 women who both delivered and had the IUD inserted vaginally (4.1 versus 20.5 per 100 women at six months post-insertion). Since the cesarean delivery rate is increasing worldwide, we deem this preliminary finding important for postpartum contraception programs and urge further studies.
