30 days after menopause, human chorionic gonadotropin, HCG, is 3765 mIU/mI, which is normal. HCG is a glycoprotein hormone composed of α and β subunits, which is mainly secreted by placental trophoblast cells formed after a woman’s pregnancy. Trophoblast cells begin to produce HCG after the fertilized egg is deposited and HCG can be measured in the mother’s serum on the 1st day, and then it doubles in size every 1.7-2 days and reaches about 100 IU/L on the 14th day after ovulation. It reaches the peak in the 8-10th week of gestation and then declines rapidly and disappears within 2 weeks after delivery. 30 days after menopause, about 14 days after ovulation, blood test for human chorionic gonadotropin is 3765mIU/mI, which is a normal phenomenon, indicating that the function of gestational trophoblast cells is relatively good, and the embryo is well developed. If there are no uncomfortable symptoms, it is recommended to go to the hospital for a vaginal ultrasound at 5 weeks after menopause. If it is a normal pregnancy, you should be able to see the gestational sac in the uterine cavity.
