Human chorionic gonadotropin, the relationship between progesterone and abortion!

  Many mothers experience these problems during pregnancy tests and begin to feel uneasy when they carry a report showing low levels of progesterone or a tendency toward "threatened abortion." But do you really know the relationship between human chorionic gonadotropin (HCG) and progesterone and abortion?

  What are HCG and progesterone?

  HCG refers to human choriotrophin, which is produced by the body on the sixth day after fertilization, when the fertilized egg is ready for implantation. HCG stimulates the production of progesterone, which can maintain the development of the embryo during the first 8 weeks of pregnancy and ensure the nutrition supply of the embryo.

  Why do we measure HCG?

  Blood beta-hcg increases rapidly in the first trimester of normal pregnancy with a doubling time of 1.7 to 2 days. In general, hCG needs to increase by at least 67% every 48 hours within 7 weeks of gestation. Urine and blood HCG levels are close, and there is a slight diurnal fluctuation, generally using the first urine or blood samples for detection. Through the determination of HCG, we can know the development of embryo, whether there is the possibility of abortion, abortion and ectopic pregnancy.

  The hCG concentration of multiple pregnancy, hydatidiform mole, choriocarcinoma and Rh blood group incompatibility was higher than that of normal pregnant women. For example, the blood HCG concentration in hydatidiform mole was significantly higher than the normal gestational reference value, and continued to rise after 8-10 weeks of menopause
