Published data showed improved Cumulative pregnancy rate and live birth rate, and a significant reduction in Miscarriage rate in In Vitro Fertilization women after hysteroscopic metroplasty of both small and large septate compared to non-operated women.

Investigators hypothesized that trans-vaginal three Dimensional Ultrasound will be superior to Hystro-salpingography for the differentiation between arcuate and septate uterus in infertile women scheduled for In Vitro Fertilization.
