What is the role of progesterone in pregnancy?

Progesterone is one of the hormones that a woman prepares for pregnancy during the menstrual cycle. Progesterone during pregnancy helps the body to adapt pregnancy and helps to develop the fetus. Progesterone levels increase during pregnancy and reach the top in the third trimester.

Steroid hormone, progesterone is naturally produced by the body. It is one of the hormones that regulates the menstrual cycle. It is also essential for healthy pregnancy and fetal development. Estrogen, another hormone involved in the menstrual cycle and pregnancy, increases the effects of progesterone. The presence of estrogen may increase the number of progesterone receptors in the cell.

Progesterone prepares an endometrium or lining of the uterus for pregnancy. In the presence of progesterone during the menstrual cycle, the endometrium is fat and contains a lot of blood vessels. This change makes the uterus a hospitable place for fertilized egg. If no egg implants in the endometrium, the blood -rich tissue is excluded during menstruationwomen.

Follicle, which releases eggs into the uterus, called corpus luteum, is the main source of progesterone for the first ten weeks of pregnancy. After the first ten weeks, the placenta takes over as the chief producer of progesterone during pregnancy. If corpus luteum cannot produce sufficient progesterone, it can lead to abortion.

The level of progesterone in pregnancy varies between women, especially in the first trimester. The level of progesterone increases during a healthy pregnancy and then drops again after birth. The decline in progesterone stimulates lactation, allowing the mother to breastfeed her newborn.

Many symptoms of pregnancy are caused by hormonal changes in estrogen and progesterone levels. Nausea or morning disease may be the result of normal hormonal activity. Progesterone during pregnancy, along with estrogen, can cause fine breasts during the first trimester and actually enlarge breasts BThe second trimester.

Progesterone is also found in the central nervous system. It can act as a neurosteroid affecting cells in the brain. It increases or reduces neuron excitability by interaction with fictional channels, which are paths that allow positive or negatively charged molecules to the cell.

Progesterone can also treat some negative symptoms of menopause. In menopause women, progesterone may also reduce the risk of uterine cancer. Younger women who do not have a normal menstrual period may take the progesterone to stimulate a normal menstrual cycle.
