Background: The causes of infertility are variable and factors such. This study critically evaluate the utility of ultrasound in the diagnosis of the female pelvic pathology. The diagnosis should be more accurate, cost effective, expeditious, reliable and as minimally invasive as possible.

Methods: The data were collected from about 750 infertile women were investigated and chosen sample was 255 cases. All patients underwent two ultrasound examinations in the follicular phase (day 13 of the cycle). Endovaginal ultrasound was done in only 80 our cases about 60 patients of them were normal and 20 of them were abnormal .13 of them had ovarian causes and 7 of them had uterine causes. Endovaginal was superior to trans abdominal.

Results: 119 case represented U/S abnormalities and the rest was normal according to ultrasound. PCO demonstrated with (73.95%) of the. Other factors represented in only (26.5%), which was subdivided into; uterine fibroid (10.92%). Bicornuate and ovarian cystic (2.52%), endometriosis, thin endometrium and septate uterus are same persentage (1.68%), congenital small uterus and ovaries ( 4.20% ) , and PID (0.84%),

Conclusion: Ultrasound is one of the non-invasive processes that provides similarly better anatomical and even better physiological data than traditional surgical procedures The role of ultrasonographic technology, especially trans vaginal, SHG, Doppler and 3D ultrasonography, can improve the female pelvic assessment. Ultrasonographic procedures should be combined as an essential examination in the basic infertility examination.
