Hello, the size of the uterus of women from childhood to menopause is from small to large, from large to small. The uterus of childbearing age is the largest. The length, width and thickness of uterus measured by B-ultrasound are 5.5 ~ 7.5cm, 4.5 ~ 5.5cm and 3 ~ 4cm respectively. The volume of uterine cavity is not less than 5ml.

During the 1 menstrual cycle, the uterine size of women of childbearing age also changes periodically due to the influence of estrogen. It is the smallest after menstruation, then gradually increases, and the volume of uterus and uterine cavity is the largest before menstruation. Some experts have studied the change of uterine cavity volume, and found that if the volume measured on the ninth day of menstruation is taken as the basic volume, its value is 5ml, and then the average weekly increase can be 1m 1, and the premenstrual volume can reach 8ml. Therefore, it is best to do B-ultrasound to measure the size of uterus at the beginning of menstruation, as a basic value, and use this value as a comparison of therapeutic effects.

If the length, width, thickness and volume of the uterus measured by B-ultrasound after menstruation is clean are less than 5cm, 4cm and 3cm respectively, it is considered as uterine dysplasia. Combined with patients: less menstrual flow, normal routine infertility examination, husband and wife living together for more than 2 years, normal sexual life and no pregnancy, can be diagnosed as uterine dysplasia infertility.

Because the data you gave is not detailed, it is not easy to judge, but you can judge for yourself according to the above. I wish you good health.
