Abstract
Uterus is a female organ that undergoes enormous variations during her genital life. To study the dimensions of the normal uterine biometry of Beninese women outside pregnancy. This study was a cross-sectional prospective study from November 05, 2009 to July 31, 2010. It involved 119 Beninese women aged 13 to 70 years identified in two ultrasonography services, namely Autonomous Centre of Radiology (CAR) of EPAC-UAC (Polytechnic School of Abomey Calavi) and the Principal Hospital of Ouidah. The study focused on women who came to ACR to undergo pelvic ultrasound. Included in our sample, women who did not present uterine pathologies such as fibroma, synechia, polyp, cancer, with no uterine scar on ultrasound. Excluded from the study, pregnant women, women who had a cesarean section. Measurements were made in longitudinal and transverse sections by supra-pelvic ultrasound. Uterine length and its thickness were performed on the longitudinal section and its width on the cross-section. The average size of the Beninese woman's uterus were: length=86.17 mm; width=49.24 mm; thickness=37.42 mm. According to the parity we have for nulliparous (length=80.08 mm; width=48.02 mm; thicknes=35.70 mm), primiparous (length=88.47 mm; width=48.24 mm; thickness=37.47 mm), multiparous (length=99.33 mm; width=52.43 mm; thickness=41.50 mm). The dimensions of the non-pregnant uterus of Beninese women were 86.17mm (lC 95%: 83.09 - 92.40) for the length, 49.24 mm (95% CI: 47.45 - 51.02) for the width and 37.42 (IC 95%: 36.02 38.81). All these dimensions increase with parity. Parity is a factor which contribute to the uterine size variation.

Summary
Knowledge of the female genital is an obligation for the gynaecologist to practice his or her specialty. Several authors have reported ultrasound uterine measurement, including length, width and thickness about to nulliparous and multiparous [5,6,7,8,9]. They had led studies but in function different stages of genital life. All previous studies were not taken place in Africa, but recently, some authors had led ultrasound uterine measurement in Ghana but a young population (nulliparous) [10]. In Nigeria this study had been carried out on both nulliparous and parous population They included in this previous study premenarche subject [11]. For our knowledge a study was not performed on Beninese
