Women with a bicornuate uterus are at an increased risk of recurrent miscarriage, preterm birth, malpresentation, disruptions to fetal growth,  premature rupture of membranes, placenta previa and retained placenta (which can lead to postpartum hemorrhage). This is due to the distortion of the normal shape of the uterus, distortion of the cervix leading to cervical insufficiency, or under-vascularization of the endometrium as the pregnancy requires more blood supply. In some cases, the nonpregnant horn can rupture during labor, necessitating emergency surgery.Fetuses developing in bicornuate uteri are more likely to present breech or transverse, with the fetal head in one horn and the feet in the other. This will often necessitate cesarean delivery. If the fetus is vertex (head down), the two horns may not contract in coordination, or the horn that does not contain the pregnancy may interfere with contractions and descent of the fetus, causing obstructed labor. Effect on intrauterine device usage
Usage of intrauterine device (IUD) with copper requires one IUD in each horn to be effective in case of bicornuate uterus. The same practice is generally applied when using IUD with progestogen due to lack of evidence of efficacy with only one IUD. Evidence is lacking regarding progestogen IUD usage for menorrhagia in bicornuate uterus, but a case report showed good effect with a single IUD. References
