Whether progesterone 50ng/ml is normal or not depends on in which stage. Normally, the normal value of progesterone in follicular stage is 0.31-1.52ng/ml; normal value in luteal stage is 5.16-18.56ng/ml; normal value in early pregnancy is 4.73-50.74ng/ml; normal value in mid pregnancy is 19.41-45.38ng/ml; postmenopausal The normal value is <0.78ng/ml. so if the patient's progesterone is normal at 50ng/ml, it is necessary to determine in which stage the patient is. I. Pregnancy: If a woman is in pregnancy, especially in early pregnancy, progesterone 50ng/ml can be considered normal. However, even if the progesterone is normal during the gestation period, it does not indicate normal development of the embryo. Generally, an ultrasound will be recommended around 6 weeks of pregnancy (6 weeks from the first day of the last menstrual period) to determine whether there is ectopic pregnancy, embryonic abortion and other conditions. Second, non-pregnancy: If a woman is in non-pregnancy, then progesterone 50ng/ml needs to be noticed, which is usually pathologically elevated progesterone. Pathological elevated progesterone is mostly caused by ovarian dysfunction. Patients are advised to first check whether their menstrual cycle is regular, and if high progesterone will affect the estrogen level. It is recommended that the patient first check the regularity of her menstrual cycle, and if the progesterone level is high, it may affect the estrogen level. Usually medication is used in clinical practice, while good lifestyle habits such as regular work and rest, healthy diet, active exercise, and a happy mood should be practiced. While regulating the ovarian function, the progesterone level will also decrease.
