Progesterone is a steroid hormone secreted by the ovaries, also known as progesterone, progesterone is generally divided into natural progesterone and synthetic progesterone, which has a great impact on the woman's uterus, ovaries, menstrual cycle and pregnancy, progesterone can promote endometrial secretion, which in turn can promote menstruation, while the fertilized egg can change the environment in the uterine cavity after the formation of fertilized eggs, ready for implantation of fertilized eggs, if the phenomenon of low progesterone in the early stage of pregnancy, it is also necessary to supplement progesterone to protect the fetus.
Some people's progesterone levels are affected by other hormones, and if the hormones in the body are disturbed, it will cause the level of progestin to decline, in addition, progesterone levels will also be affected by the following factors.

1. The decline in ovarian function is manifested in the formation of a decrease in the amount of progesterone secreted, such as polycystic ovary syndrome or premature ovarian failure, which may lead to insufficient progesterone secretion.
2. Excessive mental stress, if women stay up late for a long time, excessive mental tension and pressure are too large, it may also affect the function of the ovaries, resulting in insufficient ovarian secretion of progesterone, which may lead to menstrual disorders. For example, the postponement of menstruation or the inexhaustible.
3. Pregnancy may also lead to insufficient progesterone, early pregnancy, progesterone is secreted by the corpus luteum, if the luteal function of this period is impaired or decreased, it is easy to cause a decrease in progesterone secretion, to the third trimester, progesterone is secreted by the placenta, and the placental function disorder will also cause the level of this hormone secretion to decrease. In addition, if a pregnant woman has an ectopic pregnancy, it may also lead to a decrease in progesterone secretion.
If progesterone is in a state of low secretion for a long time, it will not only affect the menstrual cycle, but also lead to infertility or threatened miscarriage, if the level of progesterone is too low, you must go to the hospital in time for treatment to increase the content of progesterone in the body.
