Poor endocrine function is the main cause of uterine dysplasia, the main cause of poor endocrine function is insufficient secretion of estrogen and progesterone, and the cause of insufficient secretion of estrogen and progesterone is the disorder of ovarian function. Ovarian dysfunction will not only lead to poor endocrine function and uterine dysplasia, but also lead to ovulation failure and even luteal insufficiency. At the same time, this shows that there are various reasons for female infertility. First, you can take the method of B-ultrasound measurement. If the measurement results show that the length of the uterine body is less than 5cm, the broadband is less than 4cm and the thickness is less than 2cm, it means that your uterus is stunted; Second, measure the volume of the uterus. This measurement method needs to inject liquid into the cavity, so it will be more painful than the first one. If the result shows that the volume is less than 5 ml, it also means that your uterus is stunted. However, you can't simply rely on these data to conclude that the uterus is small. If the test results show that you may have a small uterus, you'd better go to a regular big hospital for a detailed diagnosis, because there are many cases in clinic that were once thought to have a small uterus, but it was not the case when you re-examined. The development of uterus needs the combination of estrogen and progesterone. Therefore, the secretion disorder of these two hormones will hinder the normal development of uterus. In addition to making the uterus benign and evil, the decline of ovarian function is a greater disadvantage to pregnancy. Such patients often do not ovulate or the luteal phase is not effective, resulting in women's infertility. Late menstruation with scanty menstruation, dysmenorrhea and even menorrhea is often a vast clinical manifestation of uterine developmental evil. Except for a few patients with small uterus who are difficult to treat because of congenital developmental disorder, most patients can have good therapeutic effect. Therefore, in order to achieve better curative effect, it is necessary to determine whether uterine dysplasia is an obstacle to congenital development. After exclusion, western medicine can be used for treatment. The correct treatment plan is to determine the factors that cause uterine dysplasia first, and restore ovarian function and secrete estrogen and progesterone normally by promoting ovulation, thus stimulating the growth and development of uterus and making infertile patients pregnant.
