When and why the embryo stops developing

Women do not need to worry about the problem of normal embryo cessation of development. However, if the embryo is abnormal and stops developing, it will seriously affect the health of the fetus. Therefore, the following content provides a detailed introduction. For many women, they can fully understand some of the reasons why the embryo stops developing.

Embryonic arrest is a common cause of female infertility. There are many reasons why the embryo stops developing. Some are due to poor development of the embryo itself and natural death. Some are due to insufficient hormone secretion to support embryo development and cause death. Some are due to uterine cavity malformations that prevent the embryo from growing. Some are due to some infection, immune and other problems. These diseases include diabetes, hyperthyroidism, etc. Under normal circumstances, the embryonic sac and embryonic bud can be seen around 40 days of pregnancy and can be clearly observed through B-ultrasound.

Once the embryo stops developing, the cause should be found. Before the cause is determined, it is not advisable to get pregnant again to avoid causing more harm. Common causes of abnormal embryonic development include genetics, infection, immunity, exposure to radioactive substances or toxic chemicals, drugs that are contraindicated for pregnant women, high temperature, excessive stimulation, etc. The embryo itself has defects or is affected by adverse factors during the development process and stops developing.

Generally speaking, it is not appropriate to preserve the fetus when the embryo stops developing, unless there is a clear diagnosis that the fetus needs to be preserved, such as luteal insufficiency. Otherwise, do not blindly preserve the fetus. In addition to the above-mentioned causes of fetal arrest, it may also be caused by contact with pregnant women or infection with viruses that are not conducive to fetal development, immune incompatibility between mother and child, or blood type incompatibility.

If miscarriage is caused by fetal growth retardation, do not rush to get pregnant again. Generally, you should consider having a child after 3 months. Instead, you should look for the cause. The four eugenics items, antisperm antibodies, antiphospholipid antibodies, anti-chorionic gonadotropin antibodies, ureaplasma urealyticum, Chlamydia trachomatis, sperm quality, egg development, etc. are all common examination items.

Reasons why the fetus stops growing:

1. Maternal disease:

Diabetes; hypertension, whether it existed before pregnancy or was caused by pregnancy-induced hypertension; sepsis, or shock caused by other reasons.

2. Baby's own problems:

Chromosomal abnormalities and congenital malformations; infection: viral infection or bacterial infection; fetal immune hemolytic disease; umbilical cord accidents: umbilical cord prolapse, umbilical cord kink, expected embolism; metabolic abnormalities.

3. Placental factors:

Placental abruption; placental insufficiency; post-term pregnancy; placenta previa; twin-twin transfusion syndrome; maternal-fetal blood type incompatibility.

4. Environmental issues:

Environmental toxins; drugs, etc.

What happens when a fetus dies in the womb?

Usually during prenatal checkups, fetal heart rate monitors and ultrasound can be used to detect the fetal heart rate and detect fetal death before the fetus is born. If the fetus dies in the womb after the second trimester of pregnancy, the pregnant woman herself will usually feel something unusual. The most obvious feeling is the disappearance of fetal movement, which can no longer be felt at all. Other signs include the uterus no longer growing with the progression of pregnancy and no weight gain or loss, but these two signs are less obvious and may take some time to be noticed. Since most pregnant women now have a scheduled prenatal checkup, most cases of fetal death are discovered during the prenatal checkup process. Some are discovered when the baby does not move during a checkup at the hospital.

The incidence of fetal death in the womb is about 6 per 1,000, more than 80% of which occur before full term, and more than half occur before 28 weeks. Thanks to advances in medicine, fetal death during childbirth is less common nowadays.

The time and reasons why the embryo stops developing. I believe that many pregnant women have fully understood the time when the embryo stops developing, and also understood some of the reasons for its developmental stagnation. So after fully understanding it, if the fetus stops developing, they must go to the hospital as soon as possible for a comprehensive examination. After finding out the cause of the developmental stagnation, they must receive symptomatic treatment as soon as possible.
