Progesterone is only 1 point or so, which is on the low side. You need to consider abnormal pregnancy, ectopic pregnancy, luteal insufficiency, endocrine disorders and so on. 1. Abnormal pregnancy: If the embryo develops abnormally after pregnancy, or even if the fetus stops, the secretion of progesterone will be reduced. 2. Ectopic pregnancy: the location of the pregnancy is not favorable to the growth and development of the embryo, which will lead to low secretion of progesterone. 3. Luteal insufficiency: with age, ovarian aging luteal insufficiency will cause low progesterone secretion. In addition, the common polycystic ovary syndrome, hyperprolactinemia and other diseases, will also appear low progesterone. 4. Low progesterone due to endocrine disorders is mainly seen in the cause of ovulatory abnormalities, such as anovulatory menstruation. If you find that your progesterone is only 1 point or more, you can go to the hospital and let the doctor check the cause in detail and treat it in time.
