There is no clear scientific basis for the value of HCG when an ectopic pregnancy embryo dies, and regular monitoring of HCG is needed to make a judgment on the death of the embryo. When a female patient has an ectopic pregnancy, there is no clear scientific basis for the value of HCG when the embryo dies as a standard, so it is impossible to judge how much HCG in ectopic pregnancy the embryo will die. Female patients using methotrexate injection and other drugs for conservative treatment of ectopic pregnancy, if the HCG value in the body drops significantly until it drops to normal, it means that the embryo may have died and the condition has basically recovered. If the female patient undergoes conservative treatment with unsatisfactory results, minimally invasive surgery or traditional surgical treatment may be required.
