For women, the role of estrogen is very large. The huge role of estrogen in women's life can not be replaced by any hormone. It dominates the development and maintenance of women's secondary sexual signs and regulates the stability of women's internal environment. When estrogen secretion is normal, women will maintain their unique beauty and have a healthy life. So what are the specific effects of estrogen on women?
1. It can promote the development of endometrium, the thickening of muscles, the increase of blood circulation, the increase of contractility and the sensitivity of uterine smooth muscle to oxytocin.
2. Estrogen on epiphysis can promote the deposition of calcium in bone, puberty can make bone closed under the influence of estrogen. However, in menopause, the secretion of estrogen is reduced, and osteoporosis is easy to occur due to the lack of estrogen in the body, which is one of the main reasons why the elderly women are prone to fracture
3. Under the action of estrogen, endometrial hyperplasia occurs periodically, thus forming the unique menstrual cycle of women. When menstruation is delayed, rare and rare, it is possible that the level of estrogen has changed abnormally, mostly due to the low secretion of estrogen.
4. Estrogen shapes women's beauty. Delicate skin, plump body, towering breast, unique curve, etc. are all closely related to estrogen. Estrogen makes mammary duct hyperplasia, nipple and areola pigmentation. Estrogen promotes the development of secondary sexual sign, makes women tend to be mature and shows the charm of girls.
5. Estrogen can relax the cervix, significantly increase the secretion of cervical mucus, thinned the quality, and easily pulled into filaments, which is good for sperm passing through; in clinical, some women's vagina is dry, which is often the expression of low estrogen; in ovulation period, due to the role of estrogen, vaginal secretion is often significantly increased, and there is a phenomenon of wire pulling.
6. Estrogen is necessary for the development of follicles. From primordial follicles to mature follicles, it plays a role in the accumulation of cholesterol in ovaries. If the estrogen level is low, there is often anovulation, or ovulation but not conception. Estrogen can also control the secretion of pituitary gonadotropin through the positive and negative feedback regulation of hypothalamus.
7. In the period of female development, estrogen plays an important role. For some female reproductive organs, such as the normal development of fallopian tube, uterus and other reproductive organs, as well as the amplitude of rhythmic contraction of fallopian tube, there is an internal relationship with estrogen. If there is a problem with estrogen, the development of these organs will be abnormal, which will cause the proliferation and keratinization of vaginal epithelial cells, and the development of labia Full.
8, the new supersedes the old. The estrogen also participates in the metabolism of the body. Estrogen can also promote the retention of sodium and water. In the aspect of fat metabolism, total cholesterol has a downward trend. &beta * - lipoprotein decreases and the ratio of cholesterol to phospholipid drops. This helps prevent coronary atherosclerosis and has a certain protective effect on the female sex. In real life, it can be seen that women's risk of coronary heart disease is very low when their ovarian function is sound.
