The causes of fetal heart stoppage can be complex, generally related to insufficient secretion of progesterone, physical factors of pregnant women, genetic factors, and endocrine factors. Moreover, if there are chromosome abnormalities, it may also lead to fetal heart stoppage. After the detection of fetal heart stoppage, timely intervention measures need to be taken, usually requiring abortion, because if the dead fetus stays in the pregnant woman's body for too long, it may cause damage to the mother.

Insufficient Hormone Secretion

If a pregnant woman experiences insufficient hormone secretion, the hormone cannot support the development of the embryo, resulting in its death.

Maternal Factors

Poor maternal health or certain diseases such as luteal insufficiency, cervical incompetence, immune factors, endometriosis, diabetes, hyperthyroidism, etc., can also affect the development of the embryo.

Genetic Factors

Genetic defects, chromosome abnormalities, and other factors can lead to embryonic arrest. Common genetic factors include abnormal egg chromosomes or sperm chromosomes.

Endocrine Factors

There are many reasons for embryonic arrest caused by endocrine disorders. The implantation and development of the embryo mainly rely on the coordination of the maternal endocrine system. When any part of the endocrine system is abnormal, it can lead to embryonic arrest. Among them, the most common endocrine disorders that can lead to embryonic arrest are luteal insufficiency and poor luteal function.

Chromosome Abnormalities

If a woman has chromosome abnormalities, it is prone to embryonic arrest, leading to miscarriage or premature birth. Chromosome abnormalities include structural and numerical abnormalities.
