Low Progesterone HCG Doubles Slowly Whether a child is born healthy or not needs to be judged on a case-by-case basis, and you can’t tell whether a child is healthy or not by having low progesterone HCG Doubles Slowly. Progesterone is an important progesterone, a hormone necessary to maintain pregnancy. The main role of progesterone is to promote the thickening of the endometrium, so that the blood vessels and glands in it proliferate, causing secretion in order to fertilize the egg to bed. If progesterone is lowered, maternal immune rejection of the fetus occurs and there is a risk of miscarriage. Measurement of progesterone is mainly used to determine ovulation, monitoring of progesterone therapy and evaluation of early pregnancy status. In normal pregnancy, HCG is produced when the fertilized egg is deposited, i.e., when the trophoblast layer of the fertilized egg is formed on the 6th day after ovulation, and peripheral blood HCG can be measured after about 1 day, and then it rises by 1 times every 1.7-2 days and reaches about 100 U/L on the 14th day after ovulation and reaches the peak at the 8th-10th week of gestation. Ectopic pregnancy should be suspected if there is no exponential increase in HCG in the interval of 2-3 days. The low progesterone HCG doubling slow in pregnancy may be ectopic pregnancy, if there is no ectopic pregnancy may also have some relationship with the embryo developmental delay, but can not be completely judged to be the development of fetal abnormalities, but also may be related to the mother’s factors, so whether the fetus is healthy can not be accurately judged. If you have low progesterone and slow HCG doubling, you should pay attention to more observation, understand your personal health condition, and regularly consult a doctor for review.
