(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.
