Why is cervical relaxation after 15 weeks and failure to perform circumcision after 20 weeks for fetal protection? Cervical relaxation is one of the problems that pregnant women are prone to encountering, which can cause an increase in the opening of the cervix and prevent the fetus from maintaining a stable position in the uterus. If pregnant women discover cervical relaxation in the early stages of pregnancy, timely measures need to be taken to ensure the health of the fetus. However, in some cases, even if pregnant women take a series of measures to prevent pregnancy, there may still be cases of failure in the end. One of the most common measures for protecting the fetus is circumcision. This article will provide a detailed introduction to the reasons for the failure of cervical relaxation after 15 weeks and cervical cerclage for 20 weeks to protect the fetus.

1. Postoperative infection: Circumcision surgery is a complex procedure that requires cervical puncture for operation. If operated improperly or without strict aseptic measures during the operation, it can lead to intrauterine infection. Infection can cause uterine contractions, exacerbating symptoms of cervical relaxation, affecting normal fetal development, and ultimately leading to fetal death or premature birth.

2. Insufficient cervical length: Before circumcision surgery, doctors will use ultrasound to check the length of the pregnant woman's cervix to determine the surgical indication. If the cervical length is shorter, the success rate of the surgery will decrease. This is because a short cervix represents a severe degree of cervical relaxation, and circumcision surgery cannot completely solve this problem, even after surgery, there may be cases of pregnancy failure.

3. Physiological and psychological status of pregnant women: Some pregnant women may experience a certain degree of mental tension and stress during pregnancy, which can have adverse effects on their physical and fetal development. For example, when pregnant women are in a state of tension, they release a large amount of adrenaline, leading to uterine contraction and insufficient blood supply, which in turn affects the normal growth and development of the fetus. Therefore, for pregnant women facing pregnancy failure, in addition to necessary medical treatment, psychological counseling and support are also needed.

4. Other physical conditions: The physical condition of a pregnant woman can also affect the success rate of pregnancy. For example, pregnant women with chronic diseases such as hypertension and diabetes, or infected with certain diseases during pregnancy, may have adverse effects on pregnancy. These issues can lead to changes in the uterine environment, which in turn affect the normal development and growth of the fetus.

In addition, due to the fact that cervical cerclage surgery cannot completely solve the problem of cervical relaxation, in addition to surgical treatment, pregnant women also need to take a series of protective measures, such as strict bed rest, maintaining emotional stability, and avoiding weight bearing. At the same time, pregnant women should also closely monitor their physical changes, seek medical attention in a timely manner, and receive doctor's advice and treatment. If premature birth, miscarriage, and other situations occur, corresponding measures should also be taken as soon as possible to ensure the health and safety of pregnant women and fetuses.

Why is cervical relaxation after 15 weeks and failure to perform circumcision after 20 weeks for fetal protection? There are many reasons for cervical laxity after 15 weeks and failure to undergo circumcision for 20 weeks, including surgical infections, insufficient cervical length, and the physical and psychological condition of pregnant women. In the face of such situations, pregnant women should closely monitor their physical changes, take a series of measures to protect the fetus, and receive treatment under the guidance of a doctor. At the same time, it is necessary to understand and master pregnancy knowledge, improve the probability of successful pregnancy, and ensure the health of mother and baby.
