Progesterone 17ng/ml at 6 weeks of pregnancy is mostly considered normal.
Progesterone, also known as progesterone, is a natural progestin secreted mainly by the ovarian corpus luteum and the placenta in early pregnancy to maintain the decidualized uterine lining, relax uterine smooth muscle, improve uterine blood supply, and immunomodulation.
The level of progesterone in the body fluctuates, and its production and secretion is regulated by luteinizing hormone (LH) secreted by the pituitary gland. LH secretion is pulsatile and cyclic, and therefore the production of progesterone is also pulsatile and cyclic, with the level of pulsatile secretion fluctuating greatly, sometimes as low as 5ng/ml.
In general, when a normal woman is 6 weeks pregnant, the value of 17ng/ml of progesterone in her body is mostly normal, and it should be noted that we can’t judge the development of the embryo based on the value of progesterone alone, and we need to analyze the situation comprehensively.
