If the uterus is found to be hypoplastic at the time of puberty and the uterus is relatively small in size, artificial cycle treatment can be done. With artificial cycle treatment, the condition of uterine dysplasia can be effectively treated with continuous medication for about six months. On the fifth day of menstruation, we start to take progesterone pills orally once a day for 21 days, and add progesterone pills once a day for 5 days when we reach the 16th pill of progesterone. Repeat the medication on the fifth day of the next menstrual cycle. It is recommended to take a total of 6 courses of treatment, which can effectively bring the uterus to normal size. In addition, if the uterus is found to be small in adulthood, it is clinically difficult to restore the uterus to its normal size again with medication in this case.
