Assessment of the uterine morphology and exclusion of the endometrial pathology are essential before commencement of medically assisted reproduction. It is clear that anatomic uterine abnormalities, including submucous leiomyomas, intrauterine adhesions and congenital uterine anomalies interfere with implantation of the developing embryo and may cause recurrent pregnancy loss. Since 3D ultrasound provides images of the uterine cavity in multiple tomographic sections, intracavitary structures become clearly visible.In this work will evaluate the role of 3D ultrasound in diagnosis of uterine causes of infertility. Also will evaluate the benefit of using 3D ultrasound over 2D ultrasound and other imaging techniques in assessment of the uterine causes of infertility.
