P

This kit is used for quantitative determination of progesterone (P) in human serum in vitro. The real progesterone in human body is progesterone. The corpus luteum of women with normal menstrual cycle is the main source of progesterone. The production rate of progesterone is about 2-3mg / 24h before ovulation and 20-30mg / 24h after ovulation. During pregnancy, progesterone is mainly produced by placenta. Progesterone is the intermediate product of the synthesis of other steroid hormones, which is 21 carbon steroid. Progesterone combines with a kind of globulin in the blood to become water-soluble and lose its activity. Progesterone is mainly degraded in the liver and can also be inactivated by other tissues. Progesterone has a thermogenic effect. After ovulation, normal women's ovaries secrete more progesterone, and their basal body temperature can rise by 0.3-0.5 ℃, which can be used as one of the ovulation indexes. Progesterone may increase the thermogenic effect of thyroxine or directly affect the temperature center of the hypothalamus, and raise the basal body temperature. In addition, the main degradation product of progesterone is a pyrogen, which can also raise the body temperature.
