Did Yang Wei have a second child through IVF? Yang Wei got twins through IVF in Thailand

The country's two-child policy has been opened, and celebrities have actively responded to the country's call. Yang Wei, the champion dad who became popular on variety shows some time ago, successfully gave birth to twin daughters. It is rumored that Yang Wei's twins are test-tube babies from Thailand. Today, let's take a look at the pros and cons of test-tube babies.

Yang Wei's twins are born

On January 16, Yang Wei posted a message to announce the good news to netizens: "The baby is coming! Thank you for your hard work, great mom!" Yang Yun gave birth to twins, Yang Yangyang became a big brother, and the family became five people.

In the early morning of January 19, Yang Wei posted a photo of the baby's feet on Weibo: "We will be discharged from the hospital tomorrow! Yesterday, we held the sixth family meeting, chaired by Brother Yang. There were two topics: one was to express gratitude to our great mother, and the other was to congratulate Brother Yang for having two deputy secretaries-general (he is our secretary-general). At this moment, the two babies have entered the mode of sleeping during the day and making noises at night. Fortunately, the mother is gradually recovering. In short, I am grateful and everything is fine!"

What is IVF?

It is the common name for the in vitro fertilization-embryo transfer (IVF-ET) technology, which refers to the whole process of taking eggs from women's ovaries, fertilizing them with sperm in vitro and culturing them for 3-5 days, and then transplanting the embryos that have developed to the egg cleavage or blastocyst stage into the uterine cavity to implant and develop into a fetus. Babies produced by in vitro fertilization technology are called test-tube babies, and these babies can also grow in the mother's uterus.

The world's first test-tube baby was born in the UK in 1978, and the first test-tube baby in mainland my country was born in Beijing in 1988. Test-tube baby technology can help infertile couples who are still unable to conceive after conventional treatment to have a baby.

The principle of IVF "IVF" is not a baby that really grows in a test tube, but a few eggs are taken from the ovaries, and they are combined with the man's sperm in the laboratory to form an embryo, and then the embryo is transferred to the uterus to implant and become pregnant in the mother's uterus. Normal conception requires sperm and egg to meet in the fallopian tube, combine to form a fertilized egg, and then the fertilized egg returns to the uterine cavity to continue the pregnancy. Studies have shown that the pregnancy rate after one cycle of treatment is about 40%, and the birth rate is slightly lower.

Can older couples have IVF?

Older couples have difficulty conceiving, can IVF work?

Wu Lan, deputy chief physician of the obstetrics department of Nanjing Maternal and Child Health Hospital, told the Yangtze Evening News that theoretically, any woman who has not reached menopause can become pregnant, but infertility due to advanced age is indeed common among women, and there are many problems, including problems with female ovarian function, fallopian tube lesions, or inability to implant, problems with the fertilized egg, etc.

As we know, the ovary is the reproductive endocrine organ that produces eggs and is the warehouse of "eggs". By the time a woman reaches menarche, the number of follicles in the ovary will reach 300,000 to 500,000. A batch of follicles will develop every month, of which only one dominant follicle can fully mature and release eggs, and the rest will degenerate on their own. In a woman's lifetime, only 400 to 500 follicles will mature and be released.

That is to say, as women age, their "inventory" becomes less or their "warehouse" becomes smaller, and their fertility will gradually decline. Especially after the age of 35, the rate of fertility decline accelerates significantly, and after the age of 40, it begins to decline in a straight line.

Only 20% of women over 40 who undergo IVF can get pregnant

An expert from the Reproductive Center of Jiangsu Provincial People's Hospital said that it is understood that the success rate of "test tube" babies depends on many factors, among which the age of the woman has the most significant impact.

The success rate of test tube babies for women aged 25 to 35 is higher than the average level of 30%-40%. After the age of 35, the success rate gradually decreases, reaching only about 20% at the age of 40. The reason is that with age, the quality and quantity of eggs decrease.

The probability of having a child with Down syndrome increases dramatically if the child is born at 45 years old

As the age of pregnant women increases, the first meiotic division time is prolonged, which can lead to oocyte aging, chromosome nondisjunction, and the formation of eggs with abnormal chromosome numbers. The probability of fetal chromosome abnormalities also increases. One of the most common chromosome abnormalities is the well-known Down syndrome.

Down syndrome is characterized by severe mental retardation, wide-set eyes, upward-slanting outer corners of the eyes, and other special facial features. Most patients have congenital heart disease, duodenal atresia, and other deformities. These patients have a long survival time and poor self-care ability, which brings a long-term and heavy burden to their families and society.

Sun Yun, deputy chief physician at the Prenatal Diagnosis Center of Nanjing Maternal and Child Health Hospital, said that the probability of a 25-year-old pregnant woman giving birth to a baby with Down syndrome is 1/1300; the probability is as high as 1/365 at the age of 35. If the pregnant woman is 45 years old, the probability is as high as 1/30.

■There is such a saying

Having a baby over 45 years old increases life expectancy

Pyles, a scholar who studies longevity in the UK, found that women who give birth after the age of 40 are four times more likely to live to be over 100 than the average woman. This is because women over the age of 35 produce a large amount of hormones during pregnancy. If they can supplement with balanced and reasonable nutrients, their organs will return to their peak state during pregnancy and lactation.

Expert: Age is not the only factor, but you must be fully prepared

Experts point out that women in their 40s, if they are in good health and have a strong desire to have children, can also try, but they must be adequately prepared.

Experts suggest that you should go to the hospital for a checkup before you get pregnant to see if you are suitable for pregnancy. You should strengthen exercise before pregnancy and strengthen pre-pregnancy management. If you have internal and external complications such as high blood pressure before pregnancy, or have undergone in vitro fertilization, have a history of adverse pregnancy and childbirth, or are obese, you must consult a doctor before you get pregnant.

In addition, folic acid should be supplemented in the first three months of pregnancy to prevent neural tube defects. During pregnancy, older pregnant women should undergo prenatal diagnosis to determine whether there are birth defects, and the growth of the fetus should be monitored regularly.

Although advanced age will increase the risk to a certain extent, excessive psychological stress is more likely to affect the outcome of pregnancy.
