What is the typical size range for a multiparous uterus?

Explanation:
Multiparity leads to a larger uterus because previous pregnancies add muscular mass and tissue remodeling, so the organ sits a bit larger even when not pregnant. A typical multiparous uterus measures about 9–10 cm in length, roughly 4.5–5.5 cm in width, and about 6–7 cm in the anterior-posterior (thickness) dimension. This reflects a moderate enlargement compared with a nonpregnant uterus, which is usually around 7–8 cm long, 4–5 cm wide, and 2–3 cm thick. The increase is most noticeable in length, with modest gains in width and thickness. The other size ranges tend to correspond to a nulliparous uterus or smaller variations, not the usual multiparous size.
