The main function of the uterus is to support the development of a fertilized egg during pregnancy. It provides a safe and nourishing environment for the embryo to implant and grow into a fetus. The uterus also plays a role in regulating the menstrual cycle by shedding its lining during menstruation. Additionally, the muscular walls of the uterus contract during childbirth to help push the baby out of the body.
