In clinical practice, at six weeks of pregnancy, fetal sprouts and primitive cardiovascular pulsations can be seen on ultrasound. This can confirm intrauterine pregnancy and ensure the survival of the embryo. Progesterone belongs to a type of progesterone. When pregnant women go for prenatal check ups, the content of this hormone is usually checked. So, is it still necessary to supplement progesterone after having fetal heart rate?
Ultrasound indicates the presence of fetal heart and fetal sprouts. Whether to use progesterone or not depends on the level of progesterone in the body. If progesterone is normal, there is no need to supplement progesterone. If progesterone is insufficient, it is necessary to supplement progesterone.
Progesterone has immunoprotective and immunosuppressive effects. There is a study that implants certain tumor cells into the uterus of animals. Only in animals injected with progesterone, the cells are not rejected and implant into the uterine wall, indicating that progesterone can inhibit immune responses. This also indicates that when women have a normal pregnancy, an increase in progesterone can prevent the embryo from being rejected by the mother and maintain the pregnancy. When progesterone is insufficient, it may cause the embryo to be rejected by the mother and result in miscarriage.
Some studies suggest that progesterone can alter the permeability of the uterine cell membrane to ions, causing the membrane to be in a super excited state, thereby reducing the excitability and conductivity of the uterine muscle, and decreasing its sensitivity to various stimuli (including oxytocin), thereby preventing the uterus from expelling the embryo and playing a role in protecting the fetus. Progesterone can also increase fetal insulin secretion by raising maternal blood sugar levels, thereby promoting fetal growth, so progesterone is very important for pregnant women.
