The normal value of progesterone at 6-7 weeks of pregnancy is 52.7-100.1 nmol/L. Progesterone protects the stability of the intrauterine environment and the growth and development of the embryo. The level of progesterone plays a crucial role in the growth and development of the fetus, but there are individual differences in the level of progesterone, and in general, no special supplementation is needed, only if the level is low and there is pre-eclampsia bleeding, timely progesterone supplementation is needed. The main source of progesterone during pregnancy is produced and secreted by the ovarian corpus luteum and placental trophoblast cells, which articulate to secrete progesterone. After pregnancy, the ovarian corpus luteum produces progesterone hormone. As pregnancy increases, the ovarian corpus luteum function decreases and the placenta gradually replaces the ovarian corpus luteum to produce progesterone. If the two are not properly articulated due to endocrine disorders or luteal insufficiency, etc., it is possible that the progesterone in the body is too high or too low, especially too low, which may affect the growth and development of the fetus and thus lead to symptoms such as miscarriage. In case of low progesterone value, you can take progesterone medication such as progesterone tablets, or intramuscular progesterone injection to supplement progesterone, so that the body level can be gradually restored, and the treatment method needs to be under the guidance of a doctor.
