Progesterone is a familiar term for everyone, and it is a value that almost every pregnant expectant mother is very concerned about, because it and hCG levels can reflect whether the fetal growth and development in the abdomen are normal. So, many expectant mothers want to know how much progesterone is normally increasing every day?
The rate of progesterone growth is not the same every day. The serum progesterone level in the body during pregnancy will steadily increase with the duration of pregnancy, ranging from 30-130nmol/L in early pregnancy, 62-260nmol/L in mid pregnancy, and 200-700nmol/L in late pregnancy. Due to individual differences in constitution and diet, there may be certain variations, but as long as they are within the normal range, there is no correlation.
Progesterone is an important hormone that supports early fetal growth and development. High concentrations of progesterone have a significant sedative effect on an enlarged uterus, and support for early pregnancy is also crucial. In early pregnancy, due to the implantation of the gestational sac into the uterus, the development is not very stable and the progesterone level is low, which can easily lead to threatened miscarriage. There are many early examinations. In the early stages of pregnancy, the progesterone level needs to be greater than 30 after 6 weeks, indicating stable development. If it is too low, medication should be used early to protect the fetus.
During pregnancy, the hCG hormone in the body stimulates the corpus luteum to produce progesterone; From 7 to 9 weeks, there will be a transition to placental production, also known as corpus luteum placental metastasis; At 10-11 weeks, the placenta produces progesterone, which also increases significantly. At this time, the nourishing cells of the placenta replace the corpus luteum to produce progesterone and maintain pregnancy. Progesterone test is mainly used to understand the function of the corpus luteum, whether the ovaries are ovulating, and to understand pregnancy status.
