Background: The diagnosis of congenital uterine anomalies and the differentiation between different subtypes is based on various sets of measurements that are difficult to implement during daily workflow. Purpose: To describe the shape and range of measurements of the normal uterus at the fundus in women of reproductive age. Material and Methods: This retrospective study was conducted on 200 pelvic magnetic resonance imaging (MRI) examinations of female patients of reproductive age with normal uteri divided into three age groups (15–24 years, 25–34 years, 35–45 years). The shape of the endometrium and serosa were documented. The thickness from the external to the internal fundic contour and the intercornual distance were measured. Results: The shape of endometrium is most commonly concave or flat but is not uncommonly convex. The shape of the serosa is convex in most cases but can be flat or concave. There is a progressive increase in thickness at the fundus with increased age with mean values of 10.8, 12.3, and 13.6 mm and ranges of 5.6–15.8 mm, 7–18.7 mm, and 7.3–19.8 mm, respectively, in the first, second, and third age groups. There is a progressive increase in intercornual distance with age with mean values of 41.4, 44.5, 47.2 mm and ranges of 30.6–50.7 mm, 31.5–57.3 mm, and 35.2–61 mm, respectively, in the first, second, and third age groups. Conclusion: Our study reports the range of normality in shape and measurement of the uterine fundus to aid in the detection of congenital uterine abnormalities.
