What causes low progesterone after pregnancy?

Most women of childbearing age hope to have their own children and hope that they can have a successful pregnancy. Progesterone is a hormone unique to women that can help women get pregnant. However, if the progesterone level of pregnant women is low, in serious cases it may lead to miscarriage or habitual abortion. So what is the reason for low progesterone during pregnancy?

What causes low progesterone during pregnancy?

1. Threatened abortion and other diseases: threatened abortion, ectopic pregnancy, premature birth, amenorrhea, infertility. If young women have suffered some injuries in the past, such as threatened miscarriage, ectopic pregnancy, premature birth, amenorrhea, infertility, etc., these will directly lead to low progesterone levels.

2. The human body develops insulin resistance: Progesterone levels play a big role for women, and play a particularly important role in women's healthy lifestyle. Pregnancy and test tube embryo development are related to progesterone levels. Progesterone helps stimulate uterine changes during childbirth, has a certain stimulating effect on the uterus, and promotes embryonic development by increasing vascular and tissue blood flow, so that the baby can be safely protected in the mother's belly.

After the egg cell is released from the uterus and ovary, it will adhere to the uterus and stick to the uterus. Theoretically, the fusion of egg cells and male sperm to produce test tube embryos is a normal physiological process. Progesterone is a kind of hormone that can delay the shedding of uterine membrane (IVF) and is a common female hormone secreted by women.

3. Luteal insufficiency: When the corpus luteum is insufficiency and the corpus luteum of the ovary is poorly developed, the progesterone value is relatively reduced.

If the function of progesterone is not complete, when the corpus luteum of the ovary is underdeveloped, the progesterone component will be relatively reduced, and the progesterone level will be relatively low compared to normal and healthy women.

Causes and diagnosis of low progesterone during pregnancy When it comes to luteal insufficiency, everyone may not be clear about what it is. In medicine, luteal dysfunction does not always refer to insufficient estrogen and progesterone secretion by the corpus luteum of a woman's ovary. If women have luteal insufficiency, it may cause luteal bleeding, embryo implantation failure, female infertility or miscarriage.

When to check progesterone level before pregnancy

1. Prenatal check-up time during non-pregnancy period

If you are checking the progesterone level in the follicular phase, it is recommended to check it 2-3 days during the menstrual period. If you want to confirm pregnancy, it is generally more accurate to test from the first day of the menstrual period to the 20th day, because around 20 days is usually the ovulation period to the follicular phase, and the progesterone value should reach a high level at this time. If the progesterone level has not risen at this time, it means that you are not ovulating or the estrogen level is too low, which may lead to miscarriage in early pregnancy.

2. Check the time during pregnancy

If pregnancy is confirmed, it is best to check within the first three months of pregnancy so that possible problems can be dealt with in time. You can check it at any time during pregnancy, and then check it again the next day. You can combine the two hCG and progesterone results for comparison.

For women who have experienced miscarriage or have menstrual disorders before pregnancy, it is important to check the progesterone level as soon as possible. The clinical manifestation of progesterone value test is to detect whether there is lipid-rich uterine ovarian tumor, corpus luteum cyst, hydatidiform mole and choriosquamous cell carcinoma. The main purpose of the test is to compare with the previous standard value. The standard values ​​between different pregnant women are not comparable.
