Introduction
In early intrauterine pregnancy, serum progesterone is primarily derived from the ovarian corpus luteum. From 6 to 9 weeks of gestation, the placenta becomes the main source. The normal range for serum progesterone in early pregnancy is as follows: at 5 weeks, the serum progesterone level is 24 ng/mL, with a normal range of 22–24 ng/mL; at 6 weeks, the normal range is 22–34 ng/mL.
In daily life, some pregnant women regularly undergo physical examinations to assess their health status. One of the indicators included in these check-up reports is the progesterone level. So, what is the normal range for progesterone levels in early pregnancy?
Normal Range of Progesterone Levels in Early Pregnancy
In the initial stage of intrauterine pregnancy, serum progesterone is primarily produced by the ovarian corpus luteum. From weeks 6 to 9 of pregnancy, the placenta becomes the main source. The normal ranges of serum progesterone during early pregnancy are as follows: At 5 weeks of gestation, the serum progesterone level is approximately 24 ng/mL, with a normal range of 22–24 ng/mL. At 6 weeks, the normal serum progesterone value ranges from 22 to 34 ng/mL, with an optimal range of 25–30 ng/mL. At 7 weeks, the normal range is 21–38 ng/mL.
If a patient has low progesterone levels, she should seek medical advice promptly to identify the underlying cause. Slightly lower progesterone levels in healthy women of reproductive age can be considered normal. However, if an older pregnant woman has low progesterone, she should visit a hospital for evaluation and, under medical guidance, may require progesterone supplementation. Low progesterone alone could increase the risk of miscarriage. Therefore, it's essential to determine the cause of decreased progesterone before starting any supplementation. Do not blindly take progesterone, progestins, or related hormonal medications without medical supervision.
Pregnant women should pay close attention to their physical health and bodily changes. If any abnormalities are noticed, please go to the hospital promptly for examination and treatment. We hope this information is helpful to you. Wishing you good health and a happy life!
