Physiological function (1) inhibits ovulation, promotes endometrial secretion, facilitates implantation of fertilized eggs, reduces the excitability of uterine muscles, and ensures pregnancy safety.
(2) Promote the growth of mammary gland acinus and prepare for lactation.
(3) Raise body temperature and relax blood vessels and smooth muscle of digestive tract.
Women with blastocysts secrete progesterone from the corpus luteum during ovulation, and the endometrium has also changed from proliferative phase to secretory phase. Progesterone can promote the development of endometrium and make embryos ovulate more easily.
The immunoprotective effect of progesterone is helpful to improve the immunity of the body. During pregnancy, with the increase of progesterone secretion, it can protect the fetus from maternal rejection and maintain pregnancy. Therefore, if the amount of progesterone secreted by pregnant women is too small, it will easily lead to fetal abortion.
Medical experiments on the role of fetal protection have proved that progesterone can inhibit the contraction of female uterus, but it does not affect the development of embryos, thus maintaining pregnancy. Progesterone can change the ion permeability of pregnant women's uterine muscle cell membrane, thus reducing the degree of uterine response to various * * * *, thus showing the role of fetal protection.
Progesterone, progesterone, is a hormone secreted by corpus luteum in women's ovaries, which regulates female endocrine. Low progesterone levels during pregnancy often lead to miscarriage. What is the specific function of progesterone?
Other functions For non-pregnant women, progesterone is a necessary substance to ensure normal physiological activities, such as maintaining the stability and regularity of menstruation. Progesterone can improve women's blood sugar level, and babies will be affected by this, producing more insulin and helping them grow. Moreover, hormones can help the uterus to synthesize some kind of protein, which has a certain protective effect on the fetus. For pregnant women, the placenta can secrete progesterone, and it will be more and more with the passage of pregnancy.
