A small uterus is mainly caused by the dysplasia of the uterine muscles, and this condition can have certain effects on the body. It can be treated with medication, such as progesterone or estradiol valerate tablets, which can replenish the estrogen in the body to promote the development of the uterus. If medication does not improve, hysteroscopic laparoscopy can be used to expand the volume of the uterus and restore it to its normal shape. The hysteroscopic laparoscopic surgery is less traumatic to the uterus, and more patients are using this method clinically with relatively good results.
