HCG is human chorionic gonadotropin, both progesterone and HCG fall, may be able to preserve the fetus, need to be judged on a case-by-case basis.
During pregnancy, if the blood HCG value is mildly decreased and the progesterone index is mildly low, then it can be regulated by later treatment, so that the purpose of preserving the fetus can be achieved after the HCG and progesterone indexes rise. If the HCG and progesterone indexes are seriously low, it suggests that the survival rate of the embryo is low, and the possibility of successful fetal preservation is generally small.
If there are fetal heart and buds, the judgment is generally based mainly on these two indexes. If there is a fetal heart, buds, progesterone and blood HCG is low, generally can also be successful in preservation of pregnancy; if there is no fetal heart, buds, then the diagnosis of embryonic sterilizations; if simple progesterone, HCG is low, generally do not need special intervention, can be supplemented with progesterone treatment.
Therefore, if the maternity test during pregnancy reveals a decrease in progesterone and HCG values, it is generally recommended to choose an appropriate treatment plan under the guidance of a doctor according to the specific situation of the pregnant woman.
