HCG refers to β-hCG human chorionic gonadotropin, referred to as HCG, is a protein hormone produced by placental chorionic trophoblast cells with gonadotropin development, its role is more, mainly including judging whether ectopic pregnancy, the basis for success in fetal protection, pregnancy maintenance, embryo protection, stimulating thyroid activity.
1, determine whether ectopic pregnancy: blood HCG examination is lower than the level of normal intrauterine pregnancy, but higher than the HCG level of non-pregnant, need to be vigilant about the occurrence of ectopic pregnancy.
2, the basis for the success of fetal protection: after the occurrence of threatened abortion, will follow the doctor's advice for fetal protection treatment, at this time can check the indicators of HCG, to determine whether the success of fetal protection, generally if HCG continues to rise, indicating that the success of fetal protection.
3. Maintain pregnancy: HCG is secreted by trophoblastic cells, which can promote the development of menstrual corpus luteum into gestational corpus luteum, stimulate progesterone production, and achieve the role of maintaining pregnancy.
4, protect the embryo: HCG can inhibit the stimulation of plant hemagglutinin on lymphocytes, avoid the mother's lymphocytes to attack the embryo, play a protective role.
5, stimulate thyroid activity: HCG can also stimulate thyroid activity, and can also bind to the TSH receptor of maternal thyroid cells, thereby stimulating thyroid activity.
In addition, the role of HCG also promotes male differentiation, etc. Therefore, if the examination finds an abnormal increase in HCG in the body, it is necessary to go to the hospital in time to improve the relevant examination and make a clear diagnosis.
