What are the factors that cause miscarriage? There are 4 major factors

The main factors that induce miscarriage are embryonic factors, placental abnormalities, maternal infection with infectious diseases, etc., which need to be actively treated according to the inducing factors.

1. Embryonic factors <br/>Abnormal embryonic development is the most common cause of early miscarriage, and miscarriage caused by chromosomal abnormalities accounts for about 50-60%.
2. Placental abnormalities <br/>Due to incomplete development of the trophoblast, degeneration of the placental villi, or the placenta being attached too low, fetal-placental circulation may be impaired, leading to miscarriage.
3. Acute infectious diseases : Pathogens or toxins invade through the placenta, causing fetal death, or uterine contractions due to high fever or poisoning, leading to miscarriage.
4. Endocrine disorders <br/>Endocrine disorders in the mother, such as corpus luteum insufficiency, can lead to decidua hypoplasia, affect the development of fertilized eggs, and may cause miscarriage.
