What does a normal uterus look like?

The normal uterus is inverted pear-shaped, located in the center of the pelvis, with the bladder in front and the vagina below the duodenum behind, with bilateral fallopian tubes and uterus and ovaries on both sides, weighing about 50-70g, about 7-8cm long, 4-5cm wide, 2-3cm thick, and a capacity of about 5ml. The uterus is divided into two parts: the body and the cervix. The body is wider and located at the upper end of the uterus; the top is called the fundus of the uterus; the sides of the fundus are called the horns of the uterus; the cervix is ​​commonly known as the cervix, which is relatively narrow and cylindrical and is located at the bottom of the uterus.

The ratio of the uterine body to the cervix varies depending on age and ovarian function. It is 1:2 during puberty, 2:1 in growing women, and 1:1 after menopause. The uterus is a triangle that is wide at the top and narrow at the bottom. The external os of the cervix of non-pregnant women is circular, while primiparas are affected by natural delivery factors and develop transverse fissures, dividing the cervix into anterior lip and posterior lip.

A normal uterus is in the shape of an inverted pear that is slightly flattened from front to back. It is divided into three parts: fundus, uterine body and cervix. The net weight is about 50g, the length is 7-8cm, the width is 4-5cm, the thickness is 2-3cm, and the capacity is about 5ml. The wider part of the upper end of the cervix is ​​the uterine body, the protruding part of the upper part of the uterine body is the uterine fundus, and the lower part of the uterine body is the cervix. The ratio of the uterine body to the cervix varies with age: the ratio in the neonatal period is 1:2, and in the elderly it is 2:1. The ratio of beautiful girls to old age is 1:1. The uterus is a muscular reproductive organ with a cavity.

The uterus is a part of the female internal reproductive organs, located in the center of the pelvis. It is shaped like an inverted pear, small at the top, middle and bottom, about the same size as a fist. It is divided into three parts: the fundus, the uterine body and the cervix. It is connected by four tendons to maintain its position in the pelvis and is not easily changed.

The tendons are the round ligament, latissimus dorsi, myofascial tendon and sacral tendon. The uterus also has a cavity with a capacity of about 5 ml, which contains the uterine wall. The endometrium plays a more important role and becomes thicker with the changes of the menstrual cycle. The endometrium is thinner during the 7 days of the clean menstrual period and becomes thicker in the second half of the period. Changes in the thickness of the endometrium are also preparations for pregnancy and are a prerequisite for normal menstruation. The uterus undergoes menstrual changes due to changes in the ovaries, and can also become diseased due to environmental and dietary factors.
