Background: An intrauterine device (IUD) is a small, often T-shaped birth control device that is inserted into the uterus to prevent pregnancy. IUDs are one form of long-acting reversible birth control (LARC). This study's objective was to compare between Post placental Insertions of different types of IUD During Cesarean Section Versus Delayed IUD Insertion. Methods: This Prospective interventional study was conducted on 300 Women who delivered via uncomplicated cesarean section and seeking IUD contraception. Patients were divided into two equal groups: PPIUD Group: women received post placental insertion of different types of IUD (50 received Copper T, 50 received Nova T, and 50 received multiload). DIUD Group: women received delayed insertion of different types of IUD (50 received Copper T, 50 received Nova T, and 50 received Multiload). Results: At 12 months follow up there was no statistical significant difference between the 2 groups as regards complications. As regards satisfaction rates, 129 were satisfied with the IUD in the DIUD group, and 118 were satisfied with the IUD in PPIUD, and this difference was not statistically significant (P-value >0.05). Prevalence of outcomes according to type of device in patients in DIUD group, data was insignificant in all outcomes except bleeding. Conclusions: Post-placental insertion of an intrauterine device (IUD) during a cesarean section appears to be a more effective and convenient method of contraception compared to delayed insertion of an IUD. Our Study have shown that post-placental IUD insertion is associated with lower rates of expulsion, thread visibility.
