Functional characteristics of human chorionic gonadotropin

  (1) with the function of FSH and LH, maintain the life of the menstrual corpus luteum, make the increase of the menstrual corpus luteum into gestational corpus luteum;

  (2) promote the aromatization of androgens into estrogen, and stimulate the formation of progesterone;

  (3) inhibiting the stimulating effect of plant lectin on lymphocytes, human chorionic gonadotropin can be adsorbed on the surface of trophoblast cells, so as to prevent embryonic trophoblast cells from being attacked by maternal lymphocytes;

  (4) LH - like function, stimulating the secretion of testosterone from the fetal testis to promote male sexual differentiation before the secretion of LH by the fetal pituitary gland; Also can promote gonadal development, to the male can stimulate the activity of testis mesenchymal cells, increase the secretion of male hormone (testosterone). It is of great significance to the treatment of male patients with pituitary joint defect, which can not only promote gonadal development and the secretion of male hormone, but also promote the development of secondary sexual characteristics.

  (5) it can bind to TSH receptor of maternal thyroid cells and stimulate thyroid activity.
