The uterus is located between the urinary bladder anteriorly and the rectum posteriorly. The average dimensions of the uterus in an adult female are 8 cm long, 5 cm across, and 4 cm thick. The uterine cavity has an average volume of 80 mL to 200 mL. The uterus subdivides into three segments, namely: the body, the cervix, and the fundus.
The uterine position is also sometimes described relative to the location of the fundus; that is, an anteflexed uterus, which is normal and where the fundus tilts forward. On the other hand, a retroflexed uterus tilts posteriorly.
With this in mind, the complex physiology and pathophysiology of the uterus having great clinical significance should come as no surprise. Common clinical complaints pertaining to the uterus will involve abnormal uterine bleeding and its associated causes, pelvic pain, and infertility.
