Cyclic changes in the ovaries

Aging is what women are most worried about and concerned about. Women have always been fighting against aging and have different views on how to maintain their appearance and body. People are worried about ageing, and the same applies to the uterus and ovaries. For women, the uterus and ovaries are very important and need to be carefully maintained. If the uterus and ovaries are allowed to age prematurely, women will also experience ageing, which will have a great impact on fertility. Women's uterus and ovaries are basically in a static state from birth to the age of 8. From the beginning of puberty to before menopause, the uterus and ovaries undergo periodic changes in shape and function. Let's take a look at the regular changes of the uterus and ovaries below.

Regular changes in the uterus and ovaries

As the egg grows and develops under the action of hormones, it continues to migrate to the surface of the uterus and ovary and protrude outward. When the egg gets close to the surface of the uterus and ovary, the surface cells at that point soften and eventually break open, and ovulation occurs. The egg is released. Ovulation generally occurs between two menstrual periods, usually about 14 days before the next menarche. Oocytes can be released from both uterus and ovaries alternately, or they can be released from one uterus and ovaries simultaneously. After the egg is discharged, it enters the fallopian tubes through the synergistic effects of the fallopian tube fimbriae, the peristalsis of the fallopian tube walls, and the microvilli activity of the fallopian tube endometrium, and moves along the lumen to the uterus.

After ovulation, the egg wall collapses, the vascular wall of the egg membrane ruptures, and blood is injected into the cavity, turning into a blood clot. The ulcer surface of the ovarian wall is quickly sealed by free fatty acids, the remaining granulosa cells enlarge, and the cytoplasm contains yellow granular cytoplasm, which is called granulosa lutein cells. At this time, the blood becomes lutein. At the same time, due to the depolymerization of the granulosa cells and the basement membrane between the ovarian endometrium, the connective tissue and capillaries of the ovarian membrane extend into the lutein center, forming a gap, making the lutein flower-shaped, and the ovarian endometrial cells also extend into the center of the lutein wrinkles and show a similar transformation, which is called the ovarian membrane lutein germ cells. 7-8 days after ovulation (about the 22nd day of the menstrual cycle), progesterone reaches its peak, which is called mature progesterone. Their sizes vary greatly, with a diameter of generally 1-2 cm. They protrude from the surface of the uterus and ovaries at varying degrees and have a yellowish appearance. At present, it is believed that the ovarian endometrial cells are the main source of estrogen before ovulation, and after ovulation, the luteal germ cells secrete estrogen and progesterone.

If the egg is not fertilized, the corpus luteum begins to shrink 9-10 days after ovulation. The general lifespan of progesterone is 12-16 days, with an average of 14 days. After the corpus luteum declines, menstruation begins, and new uterus develops in the ovaries, marking the beginning of a new cycle. The corpus luteum of the previous cycle takes 8-10 weeks to complete its decline process. Finally, the cells are absorbed, the tissues turn into fibrosis, and the appearance is white, which is called the corpus albicans.

During sexual maturity, pregnancy and lactation, the uterus and ovaries often undergo the above regular changes. However, in a woman's lifetime, only 400 to 500 eggs can complete such a complete cycle, and the vast majority of the others decline in the middle of the development stage and become blocked eggs.

How to prevent premature ovarian failure

1. Take care of your body. There are many reasons for female infertility in today's society, one of which is the impact of artificial abortion. As a woman, you must learn to take care of your body and do a good job of contraception. Too many abortions will soften the uterine membrane, thereby affecting the ovulation cycle of the uterus and ovaries.

2. Ensure adequate sleep time. No matter how busy you are at work, try not to stay up late and ensure adequate sleep. This is also one of the ways to prevent premature ovarian failure. Get at least 7 hours of sleep a day and develop a good habit of taking a nap.

3. Learn to adjust your mentality. Negative emotions can affect mood, and depressed mood can also cause the body to feel depressed and uncomfortable. Women should learn to adjust their attitude when encountering problems. They can divert their attention through some hobbies, which will also reduce the burden on the body.

4. The diet should be balanced. In daily diet, you can take some vitamins, fats and other minerals to prevent premature ovarian failure. The nutritional composition of the diet should be balanced. It is not suitable to eat too much spicy food or irritating food to avoid excessive damage to the uterus and ovaries.

5. Do moderate fitness exercises. Sitting for a long time in daily life during work will cause a certain degree of compression on the uterus, and the uterus and ovaries will also be affected. Usually, you should develop the habit of getting up and moving around after sitting for an hour, and go jogging in your free time to improve your physical fitness and enhance the ovulation function of your uterus and ovaries.

6. Try to reduce abortion surgery as much as possible. Abortion can cause great harm to the human body, especially for women who have frequent abortions, which can cause damage to the bilateral fallopian tubes, uterus, and ovaries.
