Menstruation is also known as monthly affairs, monthly water, monthly letter, holiday and so on. It is called menstruation because most people appear once a month.

Strictly speaking, with this kind of bleeding, there should be follicular maturation, ovulation and corpus luteum formation in the ovary, and the endometrial changes from hyperplasia to secretion.

What's the matter with a woman's great aunt

First, we must understand the structure and physiological function of female reproductive organs in order to explain this problem. Female internal reproductive organs are composed of ovary, uterus and fallopian tube. The main function of the ovary is to produce eggs and synthesize ovarian hormones. The uterus and fallopian tube are reproductive organs. The ovary contains hundreds of thousands of follicles, and each follicle contains one egg.

Second: before puberty, the follicles basically have no function. At puberty, under the action of gonadotropin, immature follicles gradually develop and synthesize estrogen.

Third: when the follicle is mature and ovulated, the wall of the egg collapses and the cells become large and yellow, which is called corpus luteum. It not only synthesizes estrogen, but also produces progesterone. With the change of ovary, the endometrium changes periodically.

matters needing attention

The length of the menstrual cycle depends on the length of the ovarian cycle, generally 28-30 days, but varies from person to person, there are 23-45 days, or even three months or six months for a cycle. As long as there are regular, generally belong to normal menstruation. The time of bleeding is generally 2-7 days, and the total amount of bleeding in each menstruation is not more than 100 ml.
