Progesterone main physiological functions:

1, to maintain pregnancy in female animals, pregnant animals and cause a series of physiological changes, such as the suppression of estrus females.

2, to promote uterine mucosa thickening, bending and increased glandular secretion function.

3, inhibition of uterine peristalsis, and to shrink the cervical secretion of viscous liquids. These physiological changes of the early embryo run, growth and development, implantation and post-implantation fetal growth to continue to provide appropriate environmental conditions.

4, a small amount of progestin and estrogen collaboration, promote dams estrus. Progesterone and prolactin coordination, promote the development of mammary glands.

5, progesterone participate in the hypothalamus and anterior pituitary feedback regulation, coordination and balance so that the secretion of reproductive hormones in animals. Body content, a variety of livestock follicular phase progesterone levels below 1 ng / ml in the luteal phase cattle about 4 ng / ml, pregnancy about 18 ng / ml.
