The uterus becomes distinguishable in the beginning of the fetal period (9th week) when upper part of the uterine canal forms the body (corpus) and cervix of the uterus. The adjacent splanchnic mesenchyme gives rise to the endometrial stroma, myo-metrium (smooth muscle coat), and pe-rimetrium (peritoneal covering). The fundus of uterus appears during the 4th month of development. Fusion of the caudal parts of the paramesonephric ducts brings out two transverse folds of peritoneum. Each of these folds, called broad ligament of the uterus, extends from the lateral side of the developing uterus to the pelvic wall. The uterine tube lies within the upper border of the broad ligament and the ovary is attached to its posterior surface. The uterus and the two (ie, right and left) broad ligaments divide the pelvic cavity
into two peritoneal compartments: (i) the shallow uterovesical pouch that lies between the uterus and the urinary bladder, and (ii) the deep uterorectal pouch, which lies between the uterus and rectum.
