The lack of fetal heartbeat in multiple pregnancies needs to be examined to find the cause and treated accordingly. Multiple pregnancies without a fetal heart may be related to genetic factors such as chromosomal abnormalities, male sperm abnormalities, endocrine factors, immune factors, infectious factors, and exposure to toxins during pregnancy, etc. Both men and women need to go to the fertility clinic of the hospital for consultation, and follow the doctor’s instructions to conduct the appropriate pre-pregnancy examination to identify the cause of the disease and treatment. If there is no fetal heartbeat in multiple pregnancies and the mother has had multiple abortions, which can cause great damage to the body, it is recommended that contraceptive measures be taken before the cause is identified to prevent further damage to the woman’s body and psyche.
