We can fall in love or get married at any age, but the birth of children will not give us too much waiting time.
As women’s social status continues to increase
My birth, I am the mainstream, becoming the mainstream
In addition, in order to have a better living environment
Work, social pressure
It also allows women to postpon
But my fertility, I am the master
This sentence is a thorough pseudo proposition
We can’t escape the laws of nature
Let’s take a look at Professor Liu Jiayin today
Talk about the best time for women
We all know an indisputable fact, what facts?That is, women’s reproductive ability has a deadline.We can fall in love and get married at any age, but the birth of children will not give us too much waiting time.
Well, for women, it is very important to find a child to have children in the most appropriate period of you during the limited fertility period.In recent years, genitalists and biologists have been tirelessly studying women to have children?What is the best time to give birth?
However, in the past century research, we found that the standard of "best" seems to be different, and there are differences in the calculation methods and trials. Therefore, the span between the various "best" ages calculated by scientists is veryLarge (how much span? The span is from 19-34 years old, there are 15 years in the middle).
These research results have their own solid scientific basis and strict calculation process. We cannot say which result is wrong. From different angles, the standards are different.
What we want to discuss today is that from a physiological perspective, that is, discuss "the best" from the number of eggs.We need to understand why the eggs are not renewable, and why the best time to give birth to women in their lives is only dozens of times.
First of all, we must realize that the egg is the ovarian of the ovaries that people usually call the ovaries that are not renewable.
There are two major functions of the ovary
1. secrete the necessary sex hormones for women
2. Occupible mother cells, which are usually called eggs.
Let’s explain the noun of our description of follicles here, primary follicles, follicles, follicles, and oval cells.
Follicle is composed of an oocyte (starring) in the ovarian cortex and many small follicle cells (temporary actors) around them. When ovulation every month, the two ovaries rotate each month and rotate each month.One, this follicle is a dominant follicle, and the others also have 3-11 small and medium follicles to grow up with him.
According to changes in the form and function of follicle development, we divide him into three stages: PrimordialFollic, Growing Follicle and Mature Follicle.
The mature follicles grow up quickly, with a diameter of about 20mm, full of shape, round or oval shape, and gradually moved to the surface of the ovary.After the mature follicles are generated, a instruction will be issued to the ovaries, so that the remaining follicles will not be developed, and they can only disappear and atresses.
From the last menstruation, about 14 days, then the eggs and follicles in the follicles will be squeezed out, which is what we usually call ovulation!That is the most anticipated moment for pregnant mothers.There are millions of follicles in women in their lives, but they are gradually decreasing over time.In adulthood, there are more than 100,000 oocytes.
Ovular mother cells are wrapped in primitive follicles. Under the influence of sex hormones, only one follicles are mature every month. Generally speaking, women with mature eggs in life are about 400-500.It’s right.So it is very precious.
"Eggs" are decreasing every day, which is the non -renewable resource.
In general, women aged 20-30 have "large number of eggs, low pregnancy difficulty, strong physical function, short recovery cycle, low abortion risk, less pregnancy disease, high fetal survival rate, low malformation rate, premature birth rateThe advantages of low and less genetic diseases.
From the perspective of changes in the number of eggs, a 2010 study carried out by the University of St. Andrews and the University of Edinburgh, the University of Britain. They concluded that when women were 30 years old, the number of eggs in the body decreased sharply, the number of follicles of ovarian follicles wasOnly 12%of the original reserves; and only 3%left in the age of 40.
Secondly, women’s best conception opportunities are precious.
Women have discharged about 400-500 mature eggs in their lives.And these 400-500 precious eggs play the role of birth to life. Unfortunately, the remaining oval mother cells will die.Although there are only 400-500 eggs, there are only dozens of the best chances of conception.
Because the best fertility age of women is before the age of 35. If you get married at the age of 23, only 12 years of best fertility time, only 12 ovulation in 1 year, and 144 times in 12 years.About 144 times.
In addition to the best chance of conception, the life of the egg is very delicate and short.
After the ovaries are excreted, they can only survive for 12-24 hours, and the longest can reach 36 to 48 hours.Compared to the 2-3 days of the sperm, it is too short, and only within 24 hours after the discharge, the ability to fertilize the strongest is the strongest.
Therefore, sperm can be achieved earlier to wait for ovulation, because sperm can survive in the reproductive tract for 3-4 days, then if the oval mother cells are excreted to produce fertilization, then we can have so many days to wait for the opportunity. This is a pregnancy preparing for pregnancy.Women grasped the right time.
After ovulation, the follicles form luteum. He can secrete estrogen and progesterone to regulate the synchronization of the endometrium and his tolerance.Two endings:
Ending 1 -Pregnancy
If the sperm and eggs meet in the fallopian tube, become fertilized eggs, and start to grow and develop smoothly, and start to get pregnant. At this time, the luteal will continue to grow. It is not until June and later in June or even later.
Ending 2 — Not Pregnancy
If the eggs do not meet with sperm, have not fertilized eggs, or if the embryonic bed fails, the luteal will start to degenerate from 9-10 days after ovulation, and the secretion of estrogen hormones will gradually decrease until the menstrual tide.At this time, there will be a number of new follicle development in the ovaries, and a new cycle will begin.
Therefore, women must not be blind and confident in their bodies.Especially for those who work hard to work, they often have an illusion and feel that they are not old.Although women’s per capita life span is about 80 years old, the age of menopause is still about 50 years old. That is to say, although the life span is long, the age of fertility has not been extended.
Eggs are non -renewable resources. Most women’s best conceptions are only about 144 times.After 35 years of age, the ability to give birth to a rapid decline, and after 40 years of age, it is not as good as a year.
Therefore, it is best not to miss the best age before the age of 35.
