Also under the action of this substance, the tone of the uterus and the growth of its internal cavity cease, which, in turn, also contributes to the successful implantation of the embryo. In the favorable case of pregnancy, progesterone promotes the formation of the placenta from the uterine mucosa. As you can see, the hormone affects not only the metabolism, but also the physical condition of the woman.

Norms

Depending on the phase of the cycle, the content of the hormone progesterone varies. This is due to the needs of the body.

ng / ml	0,15-1,1	0,7-1,6	1,5-2,6

These norms are established for women of childbearingage. But after the onset of menopause, the norm of this hormone is much lower - to 0.2 ng / ml. The norms of this hormone during pregnancy are completely different. So in the first trimester in the norm should be produced up to 48.6 ng / ml, in the second trimester there is an increase in the production of progesterone to 51.7 ng / ml. The largest indicator of the production of this hormone is fixed in the third trimester of pregnancy - up to 91.4 ng / ml.

Deviations from the norm

Progesterone hormone produces not only yellowthe body formed on the site of the bursting follicle in women, but also the adrenal glands. In men, this hormone is also produced by seminal vesicles. Lack of progesterone in women can lead to miscarriage or spontaneous miscarriage, and also signal the presence of cancer of the ovaries or adrenal glands.
