Estrogen secretion manifestations

Estrogen is a female hormone that girls will secrete after entering puberty, which will cause female characteristics such as menstruation and larger breasts. The secretion of estrogen is a normal phenomenon for women and a characteristic of an age stage. This hormone is produced by the ovaries and placenta. Let's take a look at the manifestations of estrogen secretion.

A physiological effect

1. Promotes uterine development, thickening of the myometrium, increased blood supply, enhanced uterine contraction, and increased sensitivity of uterine smooth muscle to oxytocin

2. Endometrial hyperplasia

3. It relaxes the cervix, increases the secretion of cervical mucus, makes it thinner and easier to pull into a thread-like shape.

4. Promote the development of fallopian tubes and strengthen the amplitude of rhythmic contraction of fallopian tubes

5. Promotes vaginal epithelial cell proliferation and keratinization, labia development and plumpness

6. Promote mammary duct proliferation and nipple and areola coloring. Promote the development of other secondary sexual characteristics

7. Estrogen is necessary for the development of ovarian follicles, and plays a certain role in the development of primordial follicles to mature follicles; it helps the ovaries store cholesterol.

8. Estrogen controls the secretion of pituitary gonadotropin through positive and negative feedback regulation on the hypothalamus

9. Promotes sodium and water retention

10. It promotes the deposition of calcium in bones and can close the epiphysis under the influence of estrogen during adolescence; osteoporosis occurs due to estrogen deficiency after menopause.

Second, the effect on women

1 In fact, in addition to the reproductive system and estrogen, many tissues and organs in the female body have its targets, such as the nervous system, cardiovascular system, bones, urinary system, etc. These systems or tissues can all interact with estrogen, so the role of estrogen is indispensable to these systems in the process of girls' development and maturation.

2 However, it is an irresistible law of nature that humans are born, grow, develop, mature, and then gradually age and die. As humans mature and decline, women's ovarian function will gradually decline and estrogen levels will drop. Women's ovarian function begins to decline at the age of 35. The symptoms are not obvious at this time, but there are some fluctuations in hormone levels.

3 However, when you reach menopause, the overall estrogen level will drop completely. After complete menopause, the estrogen level will be very low, and then menstruation and reproductive function will disappear. Generally speaking, women after the age of 45 will experience a series of menopausal symptoms due to the decrease in estrogen secretion in the body, and will develop menopausal syndrome of varying severity, mainly characterized by autonomic nervous system dysfunction.

The secretion of estrogen plays an indispensable role in the physiological development of women. The secretion of estrogen is good for the body, so everyone should pay attention to changes in their body, protect body functions, pay special attention to private areas, exercise more, and clean themselves more. Girls should take good care of their own health and read the above article. Take care of every change in your body and be careful when dealing with the unknown.
