Definition and causes of intrauterine adhesions
Uterine cavity adhesion, also known as uterine membrane adhesion, refers to the adhesion between the endometrium and the uterine wall. It is a common gynecological disease, which may affect women's fertility.
Uterine cavity adhesion can be caused by many factors, such as endometritis, uterine surgery, curettage, abortion, etc. These factors will lead to endometrial damage, trauma or infection, which will lead to inflammation and tissue healing disorder, and ultimately lead to the formation of intrauterine adhesions.
In some cases, intrauterine adhesions may be asymptomatic, and women may not know that they have this problem. However, when women try to carry out the IVF process, intrauterine adhesions may become an important problem.
Effect of intrauterine adhesion on test tube infants
1. Endometrial adhesion problem: uterine cavity adhesion may lead to normal adhesion of endometrium on the uterine wall. Under normal circumstances, the good attachment of endometrium is the key step for IVF to successfully embed into the uterus. If uterine cavity adhesion leads to endometrial attachment problems, it may affect embryo implantation and development, thus increasing the risk of abortion.
2. Abnormal shape of uterine cavity: adhesion of uterine cavity may also lead to abnormal shape of uterine cavity. The normal uterine cavity should be of proper size and shape to facilitate the development and embedding of pregnant eggs. If uterine cavity adhesion leads to abnormal shape of uterine cavity, it may limit the development space of embryo and cause abortion.
3. Damage to uterine peristalsis: uterine cavity adhesion may also have adverse effects on uterine peristalsis. Uterine peristalsis is the process of contraction and relaxation of the uterine wall, which is crucial to the transfer and implantation of embryos in the uterus. If uterine cavity adhesion interferes with uterine peristalsis, the embryo may not be able to move and embed normally, increasing the risk of abortion.
Diagnosis and treatment of intrauterine adhesions
Uterine adhesion is usually diagnosed by ultrasonography. Ultrasonography can help doctors observe the condition of endometrium and evaluate the degree and type of intrauterine adhesion.
Once the intrauterine adhesion is confirmed, the goal of treatment is to separate the adhesion tissue and restore the normal structure and function of endometrium. Common treatment methods include hysteroscopic surgery and adhesion cutting of intrauterine adhesions. These operations can help restore the normal shape and function of the endometrium and improve the success rate of IVF.
However, the treatment of intrauterine adhesions is not always successful, and sometimes it may require multiple operations to completely repair. In addition, the operation itself may lead to endometrial damage again, increasing the risk of miscarriage.
Summary
Uterine cavity adhesion is a common gynecological disease, which may affect women's fertility. In the process of IVF, uterine cavity adhesion may lead to endometrial attachment problems, abnormal uterine cavity morphology and damage to uterine peristalsis, increasing the risk of abortion. The diagnosis of intrauterine adhesions is usually made by ultrasonic examination, and the treatment methods include hysteroscopic surgery and adhesion cutting. However, the treatment of intrauterine adhesions is not always successful and may require multiple operations to completely repair. Therefore, for IVF, intrauterine adhesion is a problem that needs attention and timely treatment.
