Reasons why the gestational sac stops developing

For many pregnant mothers, what they are most concerned about is the growth and development of their children in their bodies. Therefore, when the gestational sac stops developing, many mothers are particularly worried. They are worried that this situation will cause serious harm to the baby in their bodies. Therefore, many mothers want to fully understand the reasons why the gestational sac stops developing. The following is a detailed introduction so that you can have a comprehensive understanding.

1. Endocrine disorders: During the early development of the embryo, three important hormone levels are required, namely estrogen, progesterone, and human chorionic gonadotropin. As for the mother, if the endocrine system is out of balance, resulting in insufficient endogenous hormones, the needs of the embryo cannot be met, which may cause embryonic arrest and miscarriage.

2. Immune factors: The embryo or fetus in the uterus is actually an allogeneic transplant. Since the fetus is a combination of the genetic material of the parents, it cannot be exactly the same as the mother. If there is immune incompatibility between mother and fetus, it may cause the mother to reject the fetus.

3. Uterine abnormalities: The internal environment of the uterus and the overall environment of the uterus may affect embryonic development. The internal environment is the endometrium. If it is too thin or too thick, it will affect implantation. The external environment refers to abnormal uterine development, such as a single uterus, a double uterus, and a bicornuate uterus resulting in a narrow uterine cavity. This is often due to the smaller uterine cavity than normal, which leads to abnormal embryonic development when the embryo develops to a certain number of months.

4. Chromosome problems: Chromosome abnormalities include quantitative and structural abnormalities. Quantitative abnormalities can be divided into aneuploidy and polyploidy. The most common abnormal karyotype is triploidy, and trisomy 16 accounts for 1/3 and is often lethal. Current research on chromosomes believes that chromosomes pair, exchange and separate to form gametes, and gametes combine to form zygotes. If the zygote is abnormal, it will not develop normally, which may lead to miscarriage, stillbirth, or deformed baby.

5. Reproductive tract infection: Severe reproductive tract infection in early pregnancy can cause fetal death or miscarriage, and milder infection can also cause fetal malformation. Studies in recent years have shown that mycoplasma infection is related to embryonic arrest, and the positive rate of mycoplasma infection in cervical secretions of women with embryonic arrest is significantly higher than that of normal women, and the difference is extremely significant.

6. Environmental factors: Environmental factors can directly act on the central nervous endocrine regulatory system, causing reproductive hormone secretion disorders, decreased fertility and abnormal embryonic development. These include physical factors such as X-rays, microwaves, noise, ultrasound, high temperature, and heavy metals such as aluminum, lead, mercury, and zinc that affect the implantation of fertilized eggs or directly damage the embryo and cause miscarriage. And bad living habits such as smoking, alcoholism, coffee, drugs, and certain medications all affect early embryonic development.

The above content provides a detailed introduction to the reasons why the gestational sac stops developing for many pregnant women. Therefore, for many pregnant women, in order to ensure the health of the baby in their body and the normal development, after fully understanding the above reasons, in order to ensure the normal development of the baby in the body, they must choose a large hospital as soon as possible, conduct a comprehensive examination, find out the cause of the disease and treat it as soon as possible.
