The absolute value of serum HCG varies greatly between different stages of pregnancy and pregnant women, that is, it is different from person to person, and there is no comparability, so we can only compare it ourselves. Normal non-pregnant women's blood HCG
Urine -HCG(HCG semi-quantitative method): 5000IU/L for non-pregnant women, 60-70 days pregnant > (8-32)× 104IU/L (the morning urine HCG level is the highest, close to the serum level).

Function of HCG
(1) has the effects of FSH and LH, which can maintain the life of menstrual corpus luteum and enlarge it into pregnant corpus luteum;
(2) inhibiting the stimulating effect of plant lectin on lymphocytes, human chorionic gonadotropin can be adsorbed on the surface of trophoblast to prevent embryonic trophoblast cells from being attacked by maternal lymphocytes;
(4) LH-like function, which stimulates fetal testis to secrete testosterone to promote male sexual differentiation before fetal pituitary secretes LH; It can also promote gonadal development, stimulate the vitality of leydig cells in men, and increase the secretion of androgen (testosterone). It is of great significance for the treatment of male patients with premature pituitary closure, which can not only promote gonad development and secretion of male hormones, but also promote the development of secondary sexual characteristics.
