Watching the news, a pregnant woman gave birth to twins, and the two children belonged to half-brothers. What is the reason?

Two days ago, a news about "half twins" was hotly searched.

According to news reports, on March 25th, the Judicial Expertise Center in Zheng Tai, Fujian Province confirmed that a pair of twin boys had been confirmed as half-brothers.

In this regard, people who eat melons have said that even TV dramas dare not do this!

The man took the twins for paternity test, and the results showed that they were half-brothers.

Mr. Yang from Xiamen is the father of twin children. One thing has been bothering him-his twin sons look nothing alike.

One person's eyes, mouth or nose are nothing like himself.

Despite his doubts, Mr. Yang never thought that the child was not his own.

Mr. Yang needs to provide paternity test because he wants to register his children.

So, in the first half of last year, he took his twin sons to the judicial expertise center.

A week later, the identification results came out: according to the typing results of DNA genetic markers, the biological blood relationship between father and son was not supported.

In other words, although the two children are twins, one of them is not biological.

By the way, aren't twins all the same mom and dad? Why are there half-twins?

What happened?

Twins are divided into two kinds, identical twins and fraternal twins.

Fertilization is a wonderful process. After tens of thousands of sperm compete fiercely, only the strongest can enter the egg best.

Only one sperm is allowed to enter each egg, and there will never be a second one.

As soon as a sperm enters an egg, the egg immediately changes its structure and prevents other sperm from entering.

At this point, the fertilized egg is formed. If a fertilized egg splits into two, and these two embryos develop into two fetuses at the same time, they are called identical twins.

Identical twins (females) have the same sex, blood type, antigen type and appearance, so it is difficult to distinguish them.

However, if a woman releases two eggs within one month, and the two eggs are fertilized at the same time, they develop into two fetuses, which are fraternal twins.

The sex of fraternal twins (females) can be the same or different; Blood types can be the same or different; They look like brothers and sisters, a little like them, but not exactly the same.

Identical twins only account for about 1/3 of twins, and most twins are fraternal twins.

We often say that twins are fraternal twins.

So, why are there half-twins?

After the ovum is discharged from the ovary, the survival time is generally less than 36 hours, and the fertilization ability only lasts for about one day; Sperm can survive for several days after entering vagina, but its fertilization ability can only last for about one day. This is the possible basis for half twins.

The conditions for its occurrence are very harsh:

First, the woman must ovulate two eggs in succession.

If the woman only releases one egg, even if she has sex with two men successively, this egg can only be combined with the sperm of one of them; Even twins are identical twins. Mom and Dad are the same. There will never be half a twin.

One woman and two men, double entry and double exit, is excusable. (romantic)

Two gardeners planted seeds in the same garden in a short time interval, and all the flowers survived.

It can only show that the soil in this open garden is very good, and the gardener is willing to rush to plant it, and there will be more flowers in the future.

The picture was taken by a mobile phone.

I have seen similar news. A woman went to a bar for a bachelor party on the eve of her wedding. After drinking too much, God knows which man she had sex with, but she still doesn't know. ; I got married the next day and had sex with my legal husband at night without a condom. Later, I got pregnant, and the hospital examination was twins.

After the two boys were born, their in-laws were very happy. As the children grow up, one of the two children is exactly like her husband, but the other is different. The husband became suspicious and secretly took it for DNA testing, but the result was not his own. The end result is that the child's mother left home with her child who didn't know her father.

Later, experts explained that having sex with two men at the same time in extreme time, it is extremely unlikely that their sperm will cross the finish line to reach the egg at the same time, thus achieving the wonderful phenomenon of twin half-brothers.

What is the reason? Major news media revealed. Let's not discuss the physiological reasons here for the time being, because the problems behind this matter are even more terrible.

With the development of today's society, people are more and more open, and sexual behavior is no longer a difficult thing to talk about. As a result, all kinds of derailment events emerge one after another, from star big coffee to unknown people. More and more people have joined the army of cheating. What is the reason for the derailment? This is worth pondering!

With the social transformation, ideological emancipation and the influx of western ideas, people's values have undergone major changes under the collision of Chinese and western cultures. Gradually abandon the "three obedience and four virtues" left by our ancestors. It is not that "three obedience and four virtues" must be respected, but at least it should not be abandoned from beginning to end. What is said here is loyalty to marriage and love, and remarried families are not included. After all, everyone has the right to pursue happiness.

Nowadays, people no longer live with their partners in a down-to-earth way as in the past. Too many people eat in bowls and watch in pots. Foreign monks can recite scriptures, and other people's wives and men are better than their own. With the improvement of material life, more cheating is to seek excitement to satisfy physical desires. Cohabitation before marriage has been accepted by the public and is no longer a shameful fornication.

More and more good women appear in public places, go in and out of various places, dress up beautifully, and dude is dressed up. They are no longer satisfied with "monogamy", and in their spare time, they take part in various occasions to hunt for sex. The derailment of some star big coffees has set an "example" for everyone. Imitating stars is "fashion".

In this era of rapid network development, social platforms emerge one after another, and many unscrupulous platforms are doing shady activities driven by interest pairs. More and more young people are addicted to it and gradually lose themselves. It brings convenience to derailment. "Making an appointment with a gun" has become an important part of life pursued by the next large number of people.

This mother who can still cheat during pregnancy is really irritating. Despite the fact that having sex during pregnancy is not good for fetal development (maybe she didn't know she was pregnant at that time), she had found a stepfather for her child before she was born. She doesn't want to think about what she should do when the child grows up and knows the truth. This mother is also a strange girl, a "blessed" mother with twins. But the fact that twins are not "twins" and have different fathers really bothers her. I really don't know how the two brothers will get along in the future.

Therefore, we should return to normal life and face up to the concept of marriage. As for why this happens in physiology, we don't need to delve into it too much. After all, it is not a glorious thing.

This story is full of doubts. First of all, does registration require paternity test? Another is that my father's paternity test turned out to be a half-brother. Did my mother go to the paternity test together? Does the mother also suspect that the child is not her own? If the mother didn't do the paternity test, how did the half-brother get the result?

This is big news, you can't answer it. Only ask your birth mother will the truth come out.

First of all, such a probability exists.

Secondly, my mother may or may not know the truth. This is the first time I have seen such news.

Finally, as for the ending, we should treat our children well.

If the news is true, only one thing will happen. This woman had sex with two people at the same time or successively in a very short time, and was pregnant with two men's children at the same time. This also shows that this woman is easy to conceive, or just at the best stage of pregnancy and has slept with two men at the same time or successively.

In general, if there is no problem in the test, then the twins must have two different fathers, that is to say, the twins are half-brothers and sisters. In this case, they must have been married to different people twice at the same time. The survival time of sperm in human body is about 48 hours to 72 hours, while the survival time of eggs is about 12 hours. /kloc-having sex within 0/2 hours is easy to get pregnant. In other words, this woman should have had sex with two different men within 12 hours, which led to the twins having two fathers.

Some friends didn't take contraceptive measures, and they didn't get pregnant for a long time. However, this woman slept with two people at the same time, and both of them made her pregnant and pregnant with twins. This only shows that this woman may be pregnant easily, and another reason is that she slept with her on the day of ovulation.

So how to calculate the ovulation period?

If the menstrual cycle is regular and you want to get pregnant successfully, you can choose to have the same room during ovulation, which can improve the chances of successful pregnancy.

If the menstrual cycle is irregular, it is difficult to calculate ovulation period. We can grasp the ovulation period by measuring the basal body temperature and mucus method, so as to improve the chances of pregnancy.

In addition, too long menstruation is easy to be infected, and it is difficult to get pregnant successfully. In case of infection, you should go to the hospital for gynecological examination, find out the cause, give professional treatment, and then consider pregnancy after successful treatment.

For those who have not succeeded in getting pregnant for a year, they may envy this woman's high pregnancy rate, but for this woman, I think it is always a bad thing to have sex with two men at the same time, drifting on the edge of emotion and morality, and betting tomorrow with youth, no matter whether these two men are husbands or lovers, whether one happens for a few hours first or at the same time. This is the maternal's own personal behavior, and we can't interfere with it, but I feel lucky that I don't take contraceptive measures and even have sex with another person behind my husband's back. As the saying goes, there is no windtight wall, and something will happen one day. Is it rare that families break up or even die because of extramarital affairs? Even if it doesn't lead to family ruin, unexpected pregnancy, and then abortion, abortion is not good for your health, so I also suggest that netizens don't gamble their youth and health on tomorrow for the sake of temporary enjoyment. Husband and wife are fate, children are debts, and when there is no affection between husband and wife, the best way is to divorce, not to find a lover.
