Uterus

Size
The uterus is 7.5cm long, 5cm broad, 2cm thick, 80-100g in weight. It is shaped like an inverted pear.

Position & Fixation
The uterus is normally anteverted and anteflexed, so its weight is lying on top of the bladder. When bladder or rectum fills, its position changes accordingly.

It receives passive and active support:
 * Actively:
 * 1) by the broad ligament of uterus
 * 2) by the cardinal ligament extends from the cervix and lateral parts of the vagina to the lateral walls of pelvis, thus keeping the axis in place.
 * Passively:
 * 1) by the pelvic diaphragm
 * 2) via the way it is anteflexed and anteverted, thus resting on the bladder.

Topographic relations:

 * Laterally:
 * 1) Broad ligament
 * 2) Cardinal ligament
 * 3) Ureters


 * Anteriorly:
 * 1) Vesicouterine pouch
 * 2) Superior part of urinary bladder


 * Posteriorly:
 * 1) Rectouterine pouch
 * 2) Anterior part of rectum
