Whether progesterone 15ng/ml is normal or not should be judged on an individual basis, without pregnancy progesterone 15ng/ml may be normal, during pregnancy progesterone 15ng/ml is generally abnormal.
No pregnancy progesterone value is not fixed, with the cycle of the menstrual cycle changes, in the menstrual period just after the end of the follicular phase when the value is relatively low, and then gradually rise, in the ovulation period when the value is relatively large, with the passage of the ovulation period, the value of the progesterone will decline again, the progesterone 15 ng / ml is the detection of the ovulation period, and its value is normal.
Progesterone increases significantly after pregnancy, the value of progesterone in the early stages of pregnancy should be greater than 25ng/ml, with the prolongation of pregnancy, progesterone will gradually rise, progesterone 15ng/ml after pregnancy is considered to be low progesterone, which may be caused by luteal insufficiency, due to insufficient luteal secretion of progesterone, luteal gland premature decline caused by the luteal gland, which may increase the chance of miscarriage and fetal arrest.
The normal value of progesterone needs to be analyzed in relation to whether you are pregnant and the period of time you are in, and it is not possible to generalize, and those who have abnormalities should consult a doctor in time for treatment.
