The relationship between progesterone and estrogen. Estrogen and progesterone act in harmony with each other. Estrogen is an important hormone for the maintenance of female secondary sexual characteristics, and progesterone promotes ovulation in women, and estrogen has ovarian and placental production. Progesterone is a natural progesterone secreted by the corpus luteum of the ovary. Progesterone has an effect on the endometrial morphology inspired by estrogen and can maintain pregnancy. If low progesterone during pregnancy is likely to cause miscarriage, and low progesterone in general is likely to cause low menstrual flow and amenorrhea, it is best to go to the hospital for examination in time and use hormone medication reasonably under the guidance of the doctor to regulate. If there is miscarriage, amenorrhea, changes in the endometrium, etc., it may be caused by low estrogen or progesterone, so you can go to the hospital to have a blood test for hormone six, and then under the guidance of the doctor, use reasonable medication to regulate. Pay attention to rest and don’t stay up late to prevent endocrine disorders.
