Where is the uterus?

Dr. Mehmet Oz, MD
Cardiologist (Heart Specialist)

The uterus is a pear-shaped organ nestled in the pelvis flanked by two fallopian tubes and ovaries. It is the focus of the reproductive system. During fertile reproductive years, every month the lining engorges with a nutritious blood supply with the expectation of receiving and implanting a fertilized egg. If that doesn't occur, the uterus sheds the lining during menstruation and repeats the process as long as the necessary hormones are adequate. If all the hormones are aligned and the attachment surface is a good one, a pregnancy can occur. The uterus grows to accommodate the fetus and placenta and contracts during labor.

The uterus is a muscular, fist-sized organ shaped like an upside-down pear, located in the pelvis. The primary job of the uterus is to harbor a growing baby during pregnancy. Uterine muscles contract during orgasm, producing a pleasurable sensation.

The uterus is a hollow, pear-shaped organ located in a woman's pelvis between the bladder and the rectum. The narrow, lower portion of the uterus is the cervix; the broader, upper part is the fundus. The fundus is made up of two layers of tissue. The inner layer of the uterus or the endometrium goes through a series of monthly changes known as the menstrual cycle. The outer layer of the corpus, the myometrium is smooth muscle tissue that expands during pregnancy to hold the growing fetus and contracts during labor to deliver the child.

The uterus has three major functions: to prepare an area for a fertilized ovum, to nourish the developing embryo during pregnancy, and to expel the fetus at birth. During the woman’s reproductive years the uterus is a highly dynamic organ, its functions being controlled by estrogen and progesterone secreted by the ovaries and by other hormones associated with pregnancy and labor.
