Normal progesterone values for two months of pregnancy

Progestin is a steroid hormone produced by corpus luteum in early pregnancy. After 8 to 10 weeks of pregnancy, placental syncytial trophoblasts begin to produce progesterone. Blood progesterone gradually increases with pregnancy, reaches a peak at 8 to 10 weeks of pregnancy, and then gradually decreases to a certain concentration to maintain it after delivery. Progestin plays an important role in physiological changes of endometrium, myometrium, mammary gland and other maternal systems during pregnancy under the synergistic action of estrogen. Progestin values will increase after pregnancy, but there is no specific normal range, and there is a large individual difference, it is recommended to monitor chorionic gonadotropin and gynecological ultrasound to understand embryo development.
