For many women, getting pregnant is not an easy task, especially for those who experienced fetal arrest during their first pregnancy, it is even more difficult to conceive again. However, some women experience fetal arrest due to low progesterone levels during both pregnancies. So, what is the reason for fetal arrest due to low progesterone levels during both pregnancies?
The situation of low progesterone and miscarriage after two pregnancies may be due to insufficient luteal function affecting progesterone, or it may be caused by chromosomal problems. In early pregnancy, progesterone mainly comes from the corpus luteum. After eight to ten weeks of pregnancy, placental syncytiotrophoblasts are the main source of progesterone.
If the serum progesterone level is higher than 25ng/mL, it can be basically determined that the embryo is in a normal state. If it is lower than 25ng/mL, a comprehensive evaluation needs to be conducted based on the results of blood HCG and ultrasound. If progesterone is less than 5ng/ml, it may be due to poor prognosis. If there are two consecutive miscarriages, it may not necessarily be caused solely by low progesterone.
It is recommended to receive systematic treatment for the decrease in progesterone before pregnancy, timely supplement progesterone, wait for progesterone to stabilize, and then prepare for pregnancy. After confirming pregnancy, closely observe changes in progesterone. You should go to a regular hospital for relevant examinations, identify the cause, and actively seek treatment to avoid similar problems in the future.
