Empty sacs and embryonic decontamination have the same result, there is no one more terrible in terms of empty sacs is a kind of embryonic decontamination, refers to the embryo growth and development process does not have fetal heart, buds, and full gestational sac growth. Embryonic arrest refers to the fact that initially the embryo development is good and there will be fetal heart and buds, but only after a certain stage of development, there is a stop and atrophy situation, which will lead to embryonic arrest. Most of the cases of empty sacs or embryo termination in women are related to a decrease in the quality of the fertilized egg, possibly due to genetic chromosomal disorders in either the male or the female, as well as exposure to bacteria, viruses, drugs, pesticides, and mental-emotional stress early in the pregnancy. If a woman has ever had an empty sac or embryonic sterilizations, it is best for the couple to do a full body health check before preparing for pregnancy.
