of women without a history of reproductive problems found that about 3% of women had a uterine septation; the most common anomaly in their study was an arcuate uterus (5%), while 0.5% were found to have a bicornuate uterus. In contrast, in about 15% of  patients with recurrent pregnancy loss anatomical problems are thought to be causative with the septate uterus as the most common finding.
