The value of 17α-hydroxyprogesterone, also known clinically as progesterone, varies among women at different stages of pregnancy. The normal value of progesterone is between 0.1 and 0.8 ng/ml when a woman of normal reproductive age is in the follicular phase and rises to around 0.27-2.9 ng/ml when she reaches the luteal phase. Progesterone is a progesterone hormone secreted by a woman’s ovaries and plays an important role in maintaining the normal growth of the fetus after pregnancy, therefore progesterone values can change. The normal value of progesterone in early pregnancy is greater than 25ng/ml, once it is less than the normal value, there may be symptoms of miscarriage and bleeding. If the progesterone value in the body is low, you can take progesterone drugs under the guidance of a doctor or inject progesterone intramuscularly to relieve, and do the corresponding maternity checkups on time to observe the development of the fetus and supplement the required nutrition in a timely manner.
