The probability of fetal arrest at 7 weeks of pregnancy is considered to be caused by chromosomal factors, maternal factors, paternal factors and environmental factors.
1. Chromosomal factors: chromosomal factors are mostly seen in chromosomal structural abnormalities and numerical abnormalities, which can cause abnormal development of the fetus and lead to fetal arrest.
2. Maternal factors: Commonly, there are abnormalities in the reproductive organs, such as uterine fibroids; there may be cardiovascular disease or hypertension during pregnancy; or have bad habits, such as smoking, alcoholism, etc.; there may also be endocrine abnormalities, such as luteal insufficiency, etc., resulting in fetal arrest.
3. Father’s factor: If the father’s sperm quality decreases, then the conception may also be aborted.
4. Environmental factors: if the pregnancy is exposed to too much radioactive substances or environment, then it is also easy to cause fetal arrest.
There are many reasons for embryonic arrest, so we suggest that you consult a doctor in time to find out the cause, and then complete a detailed examination before you prepare for the next pregnancy, as well as supplementing your nutrition.
