What is the normal weight of uterus in nullipara compared with multipara?

The uterus of adult nulliparous women measures 6 to 8 cm in length as compared with 9 to 10 cm in multiparous women. In non parous women, the uterus averages 50 to 70 g, whereas in parous women it averages 80 g or more. In nulliparous women, the fundus and cervix are approximately equal length, but in multiparous women, the cervix is only a little more than a third of the total length.
