Nowadays, more and more people are unable to detect the heartbeat of the embryo during the prenatal examination, and determine that the embryo is underdeveloped, that is, fetal arrest. It is understood that in older pregnant women, older pregnancy, because the embryo itself has defects, poor potential, so prone to fetal arrest and abortion risk, but in recent years in young pregnant women, the phenomenon of fetal arrest is also increasing, why now more and more people with fetal arrest?

What is the cause of fetal arrest in the third trimester?

Fetal arrest is affected by genetic factors, such as chromosomal abnormalities, genetic defects in one of men and women, generally sperm or egg chromosomal abnormalities. Pregnant women's own physical and organ factors, such as poor constitution or disease, cervical atresia, luteal insufficiency, endometriosis, diabetes, hyperthyroidism, etc., as well as uterine cavity deformity, all of which will make the embryo unable to grow.

Some are because the man has problems, such as the man's semen has a lot of bacterial growth and sperm deformity rate is high and so on. Estrogen, progesterone and human chorionic gonadotropin are the three important hormones of pregnant women. If the secretion is too low or too low to meet the needs of the embryo, it may lead to fetal arrest.

The reason of pregnant women's autoimmune ability, in the case of abnormal immunity, is also easy to lead to fetal arrest, because immune maladjustment causes maternal rejection of the fetus, leading to fetal hypoplasia. Due to the influence of external environmental factors, the diet and water source are polluted due to environmental pollution, which affects the health of human body and also leads to a series of other problems including fetal arrest.
