Chang Huan returned to Italy and brought back frozen sperm.

"That's it." Chang Huan said.

"Is it artificial insemination, or is it IVF?" Chang Huan asked.

Artificial insemination is to directly transfer sperm into the woman's body, whether it can be successfully conceived or not, it depends on the degree of sperm and egg combination.

IVF is different in that it directly puts the woman's eggs and the man's sperm in the test tube to cultivate the embryo, and when the embryo is successfully transferred directly into the woman's uterus, the success rate is high, and the gender of the baby can also be selected, but it is more painful.

There is no family planning abroad, and there is no strict management of the gender identification of infants, and IVF can choose the sex freely.

Of course, it is generally necessary to choose strong embryos and survive the fittest, otherwise weak embryos may also be miscarried.

But for the sake of prudence, two to three embryos are generally chosen, so generally people who do IVF give birth to twins.

Jiang Nan thought for a while, "It's still IVF!" ”

The success rate is higher, and if artificial insemination fails, you have to make another trip, which is easy to expose.

"That'...... Boy or girl? Or twins? Chang Huan asked again.

Of course, these are not for him to do, he does not have this level, this has to be handed over to the local doctor, but he has to ask Jiang Nan's requirements first.

"Let's have a single baby!" Jiang Nan said that at this time, if there are many things to do, I am afraid that I will be even busier if I have twins, "It doesn't matter if it is a man or a woman, choose the strongest one." ”

Chang Huan nodded, but he privately thought that Jiang Nan gave birth to a girl, as beautiful as Jiang Nan, he would definitely love her well.

Then Jiang Nan contacted a well-known local private hospital about IVF.

Start going to the hospital to monitor the follicles.

A woman's eggs are not available at any time, only on the day of ovulation.

But a woman only lays one egg a month, so it is necessary to use ovulation induction drugs, ovulation more, and take more eggs to increase the success rate of embryos.

Ovulation induction injections are painful and uncomfortable.

Because it is equivalent to excreting the eggs to be released in the future in this month, the body will be very uncomfortable. And a woman's eggs are limited, and if they are discharged in advance, they will age early, so if there is no problem, it is better to get pregnant naturally and give birth naturally.

Some people can't conceive children, and it is not easy for women to suffer a lot in order to have a child.

Jiang Nan was actively preparing for pregnancy while taking medicine.

She also began to exercise Gu Zheng.

The matter of teaching Gu Zheng to kill chickens was later reported to Gu Huailing, and he frowned and did not speak, perhaps thinking that Jiang Nan had a reason for doing this.

After the Star Fort was burned down, Gu Zheng lived in Xinyuan, he was very happy, so that he was closer to his mother, and sometimes his mother could sleep with him for a while.

It's just that I was called up early in the morning to run, and I started to feel very painful, but slowly I got used to it.

Originally, Jiang Nan also wanted to exercise, but now she is preparing for pregnancy and can't exercise vigorously.

Gu Zheng eats a lot after exercising every day, and his body has become stronger.

Jiang Nan asked people to buy simple surgical instruments, and began to teach Gu Zheng to dissect some small animals, of course, they all taught him with the method of medical knowledge, and he learned with relish.

This was very unexpected by Gu Huailing, it turned out that it could still be like this?

He remembered that the first time he killed an animal, he was so frightened that he vomited, but it was too sudden for him to bear it. Later, although he was ruthless, he had a bit of the pleasure of torture and killing, and he was very perverted.

Jiang Nan's method is very good, and he is a little impressed by her.

Half a month later, Jiang Nan went to the hospital for a follicle test, and the doctor was very happy, saying that there were several mature follicles, and he praised them for being very beautiful.

The corners of Chang Huan's mouth twitched, the follicles are beautiful?

It was the first time he had heard this, and if he had come to the reproductive department a few times, he would have heard it often, and the doctor would be very happy to see a good mature follicle.

Because some people who are not in good health do not even have mature follicles, they can only pull out the tall ones in the short ones when they have no choice, but the fertilized egg grade is poor, and even if the embryo is cultivated, it is easy to miscarry and suffer.

After the egg was retrieved, the next step was to cultivate the embryo, and the sperm had already been given to the hospital, and I heard that the sperm quality was very good.

After three days, the embryos were successfully cultivated, and two were particularly good and of high grade.

The doctor asked Chang Huan, "Two or one?" ”

Chang Huan has always accompanied Jiang Nan, and she thought that Chang Huan was Jiang Nan's husband.

"One, preferably a girl!" Chang Huan said.

The doctor nodded, there is basically no concept of preference for sons in foreign countries, so it is not strange to say to Chang Huan that he wants girls.

Then the embryo is transferred into Jiang Nan's body, and bed rest is required to make the embryo implant smoothly.

After about half a month, you can do a B-ultrasound to check whether you are pregnant.

Gu Zheng seemed very happy to know that her mother was going to get pregnant, and shouted that she had a younger sister.

"Xiao Zheng likes his sister?" Jiang Nan smiled and touched Gu Zheng's head, she already regarded Gu Zheng as her own biological child.

"Well, my sister is cute." Gu Zheng said.

"It's my sister!" Chang Huan said, he didn't want to hide it from Jiang Nan.

Jiang Nan glanced at him and didn't speak, she didn't care about boys and girls, she just wanted to have a child.

A child of that person, no, no, is his own child, he has no share!

Gu Huailing's body became weaker and weaker, he was a little anxious, and some things had not been done yet.

That night, he gave Jiang Nan a pistol and a few rounds of ammunition, "You take this for self-defense!" ”

Jiang Nan looked at his pale face, "Are you okay?" ”

"I'm fine, don't worry, everything will be taken care of before I leave." Gu Huailing said, "Xiao Zheng will be handed over to you in the future." ”

Jiang Nan nodded, "I will treat him like my own child." ”

Gu Huailing didn't doubt it at all, he saw Jiang Nan and Gu Zheng getting along during this time, even he didn't get along so well with his son.

However, he was worried that Jiang Nan would be too indulgent to his son like this, and he was afraid that he would not be able to shoulder the heavy responsibility of the Rossi family in the future.

"Don't worry, I won't spoil him, I'm just going step by step, and I don't want to cause psychological harm to the child. The Rossi family needs a tough head of the house, not a pervert. Jiang Nan said.

Gu Huailing's face darkened, did she say that she was perverted?

However, he also admitted that he himself felt that he was quite perverted, and he was only normal in the year when Gu Zheng's mother was there.

Pity......

"If you are good to Xiao Zheng, I will not treat you badly, and I will leave some things for you and your children." Gu Huailing said.

Jiang Nan smiled lightly, "Thank you!" ”

Next, Jiang Nan began to be familiar with the business of the Rossi family, and when Gu Huailing left, she would take over, and if she was not familiar with it, she would not be in a hurry when she was in a hurry, so she would not be able to explain it to the rest of the family.

Half a month later, Jiang Nan confirmed that she was pregnant.

Gu Huailing also began to take Jiang Nan into the family business to contact the company's business, although others thought it was strange, but they all thought that the new lady was curious about business to play.
