The fact that a man and a woman are united and give birth to new life is a sacred thing in itself.
The birth of every little baby is accompanied by the blessings of parents and family.
Some families hold banquets to celebrate after the birth of a new life, and in ancient times, some families even set off fireworks to celebrate.
However, many people do not know that the process of combining sperm and egg is itself a celebration process.
When the egg receives sperm, it emits a huge flash, which scientists call zinc sparks, which are very shiny and beautiful, like people setting off fireworks.
Scientists feel it's a wonderful celebration of life.
In a Northwestern University study, scientists found that during the combination of eggs and sperm, the egg bursts into a flash once it receives sperm.
It's like when fireworks bloom, they suddenly glow from the inside out.
Many people know that the combination of sperm and egg is a complex process and every life is hard-won.
However, when the egg receives sperm, it bursts into a flash, what is the principle? This needs to start with the combination of sperm and egg.
●—<精子卵子如何结合？>—●
The process of combining sperm and egg is complicated to be successful.
The sperm combined with the egg must not only successfully survive in the woman's body, but also "outperform" hundreds of millions of sperm brothers to have the opportunity to meet the egg.
This chosen sperm must first be capacitated.
That is, after the man and woman have sex, after the semen enters the woman's vagina, it must first go through a 20-minute to half-hour liquefaction process so that the semen can be fully integrated into the woman's body.
The sperm then leaves the semen and enters the woman's uterus, through the cervix, then to the uterine cavity, and finally into the fallopian tubes.
In this process, tens of millions of sperm are eliminated, and very few sperm can enter the fallopian tubes.
In this process, the glycoprotein on the surface of the sperm acrosome is also degraded by the liquid secreted by the female reproductive tract, and finally reduces the stability of the acrosome membrane.
Next, secondary oocytes emerge from the woman's ovaries and as they flow through the fallopian tubes, they encounter sperm that have been capacitated.
Chosen sperm is the sperm that first meets the egg and successfully combines.
There is only one chance of it succeeding, and that is when it meets an egg.
Chosen sperm seize the opportunity to rupture the outer membrane of the top of the head, releasing a substance called acrosome enzyme.
Acrosomal enzymes effectively dissolve the radiation tubes and zona pellucida around the egg.
When the surface of the egg comes into contact with the head of the chosen sperm, the cortical granules in the egg release a substance called lysosomal enzyme.
Lysosomal enzymes can change the main structure of the zona pellucida, forming an indestructible "shield" on the surface of the egg, keeping out other sperm who try to enter the egg.
Of course, there will be some sperm that are very cunning and successfully break through the defense, at which time the egg will combine with multiple sperm to form multiple births.
This is the process of fertilized egg formation, which typically takes 24 hours.
That's why many emergency contraceptive pills require women to take them within 48 hours to be effective.
If beyond this time frame and the sperm and egg are fully combined, the pill is likely to fail.
It should be noted that women will suffer a great degree of damage to their bodies after using birth control pills.
Because the pill forcibly strips the eggs and sperm that are about to be combined or have just been combined, this can cause damage and abnormal shedding of the woman's uterine lining.
This will not only cause women to have menstrual disorders, but also severe pain in the abdomen later in menstruation.
Not only that, if a woman takes birth control pills for a long time, it may even lead to lifelong infertility.
So if couples do not want to get pregnant, then they must use condoms correctly during sex.
This can not only effectively avoid pregnancy, but also minimize the harm to women.

When it comes to the combination of egg and sperm, it is necessary to mention the wonderful thing that when the egg receives sperm, a huge flash of light erupts.
There is such a research team at Northwestern University, and after continuous efforts, they finally captured the moment when the egg and sperm combined.
They found that the egg emits a dazzling flash the moment it receives sperm.
In their further research, they found that when the oocytes are fertilized, tens of billions of zinc ions appear on the outer wall of the cell.
These ions continue to extravade as the sperm enters the egg, resulting in the "flash" found in regular observation.
So this phenomenon is called "zinc spark" by scientists, which has caused further research by scientists.
They found that the cell activity of egg cells is affected by zinc ions, and the higher the concentration of zinc ions, the greater the activity of egg cells and the easier it is to fertilize successfully.
Not only that, after the egg cell is fertilized, zinc ions will also be actively released from the cortical granules, resulting in flashing phenomenon.
Cytokines lose their activity due to the detachment of zinc ions, and it is at this time that the fertilized egg undergoes further changes from the meiotic state and continues to develop.
And according to survey data, not only human sperm and egg combination will erupt a huge flash, but also in the combination of animals.
When studying animals such as mice and monkeys, a doctor from Northwestern University found that zinc sparks appeared within 20 minutes of fertilization of animal eggs.
And when experimenting with mice, scientists found that during the release of zinc ions into the extracellular environment, the frequency of sparks when sperm and eggs combine is very frequent.
It erupts almost every 10 minutes.
This proves that the phenomenon of zinc sparks also occurs in animals.
Therefore, whether human or animal, the birth of every life is equally sacred.
This study not only proves that the birth of life is a sacred thing, but also provides a very important solution for couples who can only rely on in vitro fertilization to conceive their babies.
This study proved to humans that before implantation of a fertilized egg, humans can assess the state of the egg by observing zinc ions to ensure that the embryo can develop and grow normally in the mother.
Not only that, the discovery of zinc sparks by scientists has also given humans a better understanding of the relationship between fertility and the proportion of zinc content in the diet.
Scientists hope to adjust the zinc storage capacity of eggs by controlling the amount of zinc in the diet, thereby improving the quality of egg cells and improving a person's ability to conceive.
However, the study is still ongoing, and there are no mature results yet.
To be sure, the amount of zinc in cells is related to the initial capacity of organisms when they first formed.
That is, the higher the zinc content in the fertilized egg, the better the baby's development.
At the same time, studies have shown that babies with high zinc content will have higher initial abilities such as IQ, EQ, and physical fitness after birth.
Therefore, pregnant women can try to eat more foods high in zinc during pregnancy to improve the baby's initial ability, such as fish and walnuts.
●—<如何提高精子质量？>—●
Although there is currently no completely scientific and effective way to better improve the quality of human embryos, there are many ways to improve sperm quality.
For example, the following methods can improve people's chances of pregnancy by improving sperm quality.
1. Maintain good living habits
With the rapid development of the social economy, people's pace of life is becoming more and more chaotic.
Many people often turn day and night upside down for some reasons such as overtime and enjoying nightlife, and there is no regular rest.
For men, it will not only make men feel tired, but also greatly reduce the quality of sperm in men, leading to infertility in men.
2. Eat more foods containing protein and zinc
For example, lean meat, walnuts, egg yolks and other foods not only contain the elements needed by the human body, but also rich in protein and zinc.
Eating more can improve prostate motility and sperm quality in men.
At the same time, men should eat less high-oil and high-salt foods and fried foods, because these will cause excessive body fat in men and affect men's sexual performance.
Being too obese can also lead to reduced sperm motility, and even if such sperm enters the woman's body, it is difficult for the woman to survive.
3. Keep exercising and improve physical fitness
In fact, men's physical fitness will also affect sperm quality to a certain extent.
Studies have shown that men with good health and physical fitness will have higher sperm quality, and the babies they give birth to will be healthier and less prone to congenital diseases.

In ancient feudal society, many people felt that a woman's inability to give birth to a son must be a woman's problem, and even thought that the inability to give birth to a son was a violation of women's ways.
Now that the social sciences are highly developed, this has been proven to be ridiculous nonsense, and scientific research has clearly proved that the birth of boys and girls is not decided by the mother.
There are 23 pairs of chromosomes in the human body, which belong to human genetic material, of which only one pair is sex chromosomes, which determines the sex of the fetus at birth.
These two chromosomes are provided by both parents.
If both are X-shaped, then the girl is born; If one is of type X and one is type Y, then a boy is born.
In the same way, the mother is also X plus X, and the father is X plus Y.
When the egg and sperm combine, the baby inherits one from the mother and one from the father.
This means that the chromosomes provided by the male are decisive for the birth of a boy and a girl.
Therefore, women cannot give birth to sons because men provide X type chromosomes.
Scientific studies have shown that the birth of boys and girls is also related to the genetic inheritance of male families.
This requires observing the composition of the male family in the couple, and if the male family has more brothers than sisters, the chance of having a boy is greater.
If the proportion of women in the man's family is larger, the chance of giving birth to a baby is a girl.
Giving birth to boys and girls is actually influenced by the man's personality.
According to surveys, if the male in the couple is careless, then more likely to have a boy; If the male character is delicate, then the chances of having a girl are greater.
So don't blame the inability to give birth to a son on women, because whether or not you can give birth to a son is determined by men's genes and personality, and has basically nothing to do with women.

Nowadays, because of their busy work, many people in society have almost become machines that can only work, neglecting themselves, and thus cannot find a sense of belonging.
There are also people who cannot find value in society, so they feel lost, and even some people take their lives because of self-doubt.
In fact, the birth of every life is a sacred thing, and when the egg and sperm are combined, a huge flash of light erupts, which is the witness of life.
Every life has its own meaning and brings different beauty to the world.
Therefore, in the face of life, people should have a sense of awe, not only cherish their own lives, but also cherish the lives of others.
It is often written in novels that when people born extraordinary are born, they are usually accompanied by weather visions and so on.
In fact, from another perspective, each of us can emit a huge light when we are still cells, so who is not a protagonist?
