According to ob-gyn Dr. Deborah Wilson, the size of the human uterus varies. However, she does stipulate that the organ generally weighs between 0.06 and 0.22 pounds. Dr. Wilson adds that the uteruses in women who have not given birth are generally smaller in size than in those who have.
Babyzone's Dr. Danne Young-Hawkins states that the uterus not only plays a primary role in the birthing process but also supports other organs in the reproductive and urinary systems, including the bladder and ovaries. According to Dr. Young-Hawkins, the uterus acts as an incubator and also provides the growing fetus with essential nutrients.
