What is the connection between estrogen and progesterone?
The body excludes female hormones estrogen and progesterone as a way of regulating various tissue functions. These substances are mainly produced by ovaries and adrenal glands in women and in the adrenal glands and testicles in men. Estrogen and progesterone cooperate on several fronts, including control of the reproductive cycle and the preparation of the female body for pregnancy. This time he is known as a follicular phase during the cycle. The body excludes estrogen during the follicular phase to develop the uterus lining, in the case of pregnancy after ovulation. The densified uterine lining promotes implantation of a fertilized egg. This hormone also works to increase blood vessel growth in the uterine, increasing and reinforcement of uterine lining. During the luteal phase, both estrogen and progesterone are excreted by the luteum, the rest of the follicle shell, which remains after the egg is released. Progesterone also works to prevent uterine contraction from pregnancy that protects the developing child. After approximately three months of pregnancy, he takes over development placenta production EStrogen and progesterone from Corpus Luteum.
during pregnancy, progesterone and estrogen prepare female breasts for lactation and the ability to treat the child after delivery. Progesterone increases the development of cells produced by breast milk, while estrogen promotes the growth of dairy channels. Estrogen also increases the production of prolactin in the body, hormone that promotes production of milk.
If pregnancy does not occur after the luteal phase, estrogen levels and progesterone decrease. Progesterone blood flow was originally promoted through the growth of blood vessels. The menstruation that occurs when the body gets rid of the uterine lining that estrogen and progesterone worked on the construction site then occur. After menstruation, the follicular cycle begins. The whole cycle, from the 1st day of menstruation to the day, when the luteal phase ends just before the start of further menstruation, usually runs 28 days.
Some women take estrogen as a formhormone substitution therapy to reduce unpleasant symptoms associated with menopause. During menopause, the ovaries secrete less estrogen, causing symptoms such as dry mouth, vaginal dryness, flashes of beats and mood swings. Estrogen replacement may be administered to reduce symptoms and to protect against osteoporosis. Progesterone replacement can be added to estrogen therapy for women who have been hysterectomy that would help control the overgrowth of uterine lining and potential for uterine cancer.
