What are the reasons for low progesterone at 40 days of pregnancy?

The health of pregnancy is directly related to the level of progesterone, so many pregnant women pay special attention to the level of progesterone during pregnancy. Many women with low progesterone at 40 days of pregnancy want to fully understand the reasons. The following content introduces it in detail. For many women who have these symptoms, you can have a comprehensive understanding.

Causes of low progesterone As for the causes of low progesterone, most of the reasons for low progesterone are due to luteal insufficiency in women, resulting in insufficient progesterone secretion by the corpus luteum. During a normal pregnancy, the increase in progesterone can prevent the embryo from being rejected by the mother and maintain the pregnancy. If there is insufficient progesterone, the embryo will be rejected by the mother as a foreign body, resulting in miscarriage. If low progesterone levels occur, it is recommended to go to the hospital in time and receive targeted and effective treatment under the guidance of a doctor.

Adverse effects

The main function of the corpus luteum is to secrete progesterone, estrogen and relaxin. Most cases of low progesterone (insufficient progesterone secretion) are caused by luteal insufficiency. Progesterone mainly acts on the endometrium, causing secretory changes in the uterus, which is very necessary for the implantation of the fertilized egg and the maintenance of pregnancy. If progesterone is not secreted sufficiently, the secretory changes of the endometrium will be adversely affected.

In clinical practice, through endometrial biopsy, it is often found that some infertile women have poor secretory function, which is not conducive to the implantation of the fertilized egg. Even if the fertilized egg implants, insufficient progesterone secretion can cause miscarriage or fetal arrest. According to statistics, 3% to 4% of women's infertility is caused by low progesterone (luteal insufficiency).

Low progesterone at 40 days of pregnancy is a relatively dangerous condition, so some women who have this symptom must pay attention to it to avoid miscarriage. After fully understanding the cause, they must go to a large hospital as soon as possible for comprehensive examination and treatment. Only through examination and treatment can they save their children from miscarriage.
