Progesterone and human chorionic gonadotropin are not directly related, but they both increase to a certain extent in the early stages of pregnancy with the increase of the gestational week. For example, in the early stages of pregnancy progesterone is a very important hormone to ensure that the fertilized egg can complete its implantation and develop normally. If the progesterone level is low, it may lead to embryonic abortion or pre-eclampsia, so if the progesterone level is low in relation to the gestational week, progesterone should be used to protect the pregnancy. The human chorionic gonadotropin in the body can effectively reflect the development of the fetus, for example, under normal circumstances, the human chorionic gonadotropin needs to be doubled at 48-hour intervals, if the doubling is not good, the possibility of ectopic pregnancy may occur, so this is also a very important reference standard in the early stages of pregnancy.
