What are the reasons for the cessation of fetal development during pregnancy?

The cessation of fetal development during pregnancy is a relatively dangerous symptom. Therefore, for many women, when the fetus stops developing during pregnancy, they will be particularly worried. Therefore, they want to fully understand the reasons why the fetus stops developing during pregnancy. In order for you to fully understand the reasons, please take a look at the detailed introduction below.

What is embryo arrest?

The fertilized egg is like a seed. It has to go through a series of complex and wonderful processes before it can eventually grow into a healthy baby. If the fertilized egg does not germinate well in the initial stage, it will most likely stop growing healthily. We call this phenomenon of embryonic development stopping in early pregnancy "embryonic arrest."

If an ultrasound examination is performed, it can be found that the fetal bud or fetus in the gestational sac is irregular in shape, there is no fetal heartbeat, or the gestational sac appears to be withered. Clinically, it falls into the category of miscarriage or stillbirth. However, sometimes pregnancy hormone levels remain high and mask the fact that the fetus has already stopped moving. In this case, you may not yet have symptoms of miscarriage. Therefore, embryonic arrest is also called missed abortion.

What are the main causes of embryo arrest?

There are many reasons that lead to embryonic arrest. The most common ones are as follows:

(1) Malformation of the uterine cavity prevents the embryo from growing.

(2) Insufficient hormone secretion makes it difficult to support embryonic development and causes death.

(3) Male factors: such as large amounts of bacteria growing in semen and high sperm deformity rates.

(4) Genetic factors: If there are chromosomal abnormalities or genetic gene defects, the most common ones are sperm or egg chromosomal abnormalities.

(5) Viral infection during pregnancy, exposure to radioactive substances, toxic chemicals, taking drugs prohibited during pregnancy, high temperature, microwaves, noise, excessive stimulation, etc.

(6) Maternal factors: such as poor physical constitution or illness, cervical incompetence, luteal insufficiency, endometriosis, immune factors, diabetes, hyperthyroidism, etc.

When the fetus stops developing during pregnancy, it is a relatively dangerous symptom. Therefore, for many pregnant women, after fully understanding the cause, in order to allow their fetus to continue to develop as soon as possible, they must go to a large hospital as soon as possible, undergo a comprehensive examination, find out the cause, and undergo comprehensive treatment as soon as possible to allow their child to develop normally.
