What are the main functions and functions of Progesterone powder USP ?

Main functions and functions
Progesterone has a wide range of functions, mainly in the following aspects:
1.Adjust the menstrual cycle
In the second half of the menstrual cycle (after ovulation), the level of Gynlutin rises, which makes the endometrium thicken and blood vessels proliferate, and turns into a state of secretion, so as to prepare for the implantation of fertilized eggs.
If the egg is not fertilized, the corpus luteum will atrophy and the progesterone level will drop, resulting in endometrial shedding and menstruation.
2. Maintain pregnancy (abortion)
This is the most famous function of progesterone. In the early pregnancy, it is secreted by the corpus luteum of the ovary, and it is secreted by the placenta in the later period.
Progesterone powder USP inhibits the contraction of uterine smooth muscle, provides a quiet and stable growth environment for the fetus and prevents miscarriage.
At the same time, it can also inhibit the immune rejection of the mother to the fetus.
3. Promote breast development
Progesterone cooperates with estrogen to stimulate the development of mammary gland acinus and prepare for postpartum lactation.
