Progesterone should be in the range of 4.73 to 50.74 ng/ml during the second trimester of pregnancy.
Progesterone is an important progesterone, a hormone necessary for the maintenance of pregnancy. Progesterone is produced mainly by the corpus luteum and originates mainly from the placenta during pregnancy, and is an intermediate in the biosynthesis of testosterone, estrogen and adrenocorticotropic hormone. During pregnancy progesterone acts mainly on the corpus luteum, regulating the synthesis of prostaglandins in this tissue. That’s why it’s important for progesterone to be normal.
The normal value of progesterone is different for each period. The normal value of progesterone in women should be between 4.73 and 50.74 ng/ml in the first trimester of pregnancy, and between 19.41 and 45.3 ng/ml in the fourth through sixth months; the normal value of mid-follicular progesterone for women (non-pregnant) is between 0.31 and 1.52 ng/ml.
If it is not within this range and the progesterone is high or low, it is necessary to consult a doctor for examination and treatment in time to avoid adverse consequences.
