What is the approximate weight of a non-pregnant uterus?

The approximate weight of a non-pregnant uterus is typically around 2 ounces. This weight can vary somewhat based on individual factors such as genetics and overall health, but 2 ounces is the general standard used in medical literature for a normal adult non-pregnant uterus. This size allows it to be a capable organ for its primary functions, including menstruation and providing a space for fetal development during pregnancy, when it significantly enlarges. Understanding this baseline weight gives insight into the physiological changes that occur during pregnancy when the uterus expands to accommodate the growing fetus, which can reach several pounds by the end of gestation. Thus, the choice reflecting a weight of 2 ounces aligns with established medical facts and serves as a foundational piece of knowledge for nursing and healthcare professionals.
