The level of progesterone between 52.7nmol/L and 100.1nmol/L at 6-7 weeks of pregnancy is normal, too high or too low may be abnormal and the cause should be clarified in time. Progesterone is secreted by the corpus luteum in early pregnancy, which can inhibit the proliferation of the endometrium and promote the deposition of glycogen in the endometrial tissue cells, providing a suitable growth environment for the fertilized egg and contributing to the development of the fertilized egg. Generally speaking, the normal level of progesterone in a pregnant woman at 6-7 weeks of pregnancy is between 52.7nmol/L and 100.1nmol/L, and anything above or below this range is abnormal. If the progesterone level of 6-7 weeks pregnant women is too low, is not conducive to the growth and development of the fertilized egg, most often seen in embryonic dysplasia, preeclampsia, etc.; if the progesterone level is too high, suggests that pregnant women’s body hormone levels are abnormal, most often seen in the staphylococcus, adrenal gland tumors, etc., and the cause of the disease should be clarified and treated in a timely manner. It should be noted that the level of progesterone in the body is in a fluctuating state, can not rely solely on a progesterone value to determine the embryo is good or bad, if the value of progesterone is abnormal, it is recommended that under the guidance of a professional physician, so as not to lead to adverse consequences.
