What is estrogen
summary
Estrogen is also produced by other body organs. It plays an important role in all of us, especially in women. It can promote the development of our body, and so on. Now, let me tell you something about estrogen.
What is estrogen
First of all: estrogen is a hormone produced by both men and women. When women enter puberty, the ovaries begin to secrete estrogen to promote the development of vagina, uterus, fallopian tube and ovary itself. At the same time, endometrial thickening leads to menstruation. Estrogen also promotes subcutaneous fat accumulation, body fullness, hyperplasia of mammary glands, nipple and areola color darker and sexual desire, and promotes retention of sodium and water in the body, and * deposition of calcium in bone.
Secondly, estrogen and progesterone in women are mainly synthesized and secreted by ovaries. At the same time, the ovary can also secrete a small amount of androgen. Estrogen before ovulation is mainly secreted by follicular endometrium, while estrogen and progesterone after ovulation are mainly secreted by luteal cells. The secretion function fluctuates with the cyclical changes of ovarian function. The ovaries mainly synthesize estradiol and estrone.
Finally: in addition to the reproductive system and estrogen, many tissues and organs in women have their targets, such as nervous system, cardiovascular system, bone, urinary system and so on. These systems or tissues can work with estrogen, so in the process of girls' development and maturity, these systems can not lack the role of estrogen.
matters needing attention
Estrogen is not exclusive to women, and it is not only needed by women. The role of estrogen in men and women is not only the same, but also different.
