Ten cognitive errors of IVF, how many do you know?
2020-04-14
In the recently popular "Wife's Romantic Trip", the female star Cheng Lisha shared her difficult pregnancy preparation. In order to give birth to a second child, she made more than 100 injections in a test tube. The endocrine disorder, depression and collapse, after the twists and turns to give birth child. For families with difficulties in childbirth, IVF is an important assisted reproductive method that can bring hope to them. According to clinical statistics, about 20% of couples in infertile patients cannot give birth at all without the help of assisted reproductive technology Parenting.
Since the development of test tube baby technology, the public's perception of her is still at a relatively primitive stage. Some people still have deep impressions and misunderstandings, which are very resistant to test tubes, resulting in missing the best time and causing irreparable shortcomings. This article sorts out some common misunderstandings of test tubes and tells you with facts how test tubes are different from everyone's imagination.
Myth 1: I heard that children born in test tubes are not related to their parents?
This depends on the source of sperm and eggs in the test tube process. To put it simply, test-tube babies take their eggs and sperm separately, fertilize them in the laboratory, wait until they have developed into blastocysts, and then transplant them into the female body to continue the process of getting pregnant in October. In most cases, the sperm eggs are provided by the couple, but the fertilization process is performed outside the body. This child naturally has a blood relationship with the couple.
If, for some reason, one or both parties cannot provide sperm and eggs, but need to "borrow eggs" or "borrow sperm," then the child is not related to the one who cannot provide it.
Myth 2: Test-tube babies perform worse than naturally-conceived children in terms of physique and intelligence
Whether it is physique or intelligence, there are reports in the literature: test-tube babies behave the same as naturally conceived children. The biggest difference between test tubes and natural conception is the "location" of fertilization. One is in a laboratory petri dish and the other is in the fallopian tube. After being transplanted in the body, the growth and development process of the IVF in the female uterus is the same as that of the naturally conceived fetus. There are also artificial rumors that test-tube babies are not fertile, and they will still have to be test-tube babies in the future. However, the case proves that this rumor is wrong: the first test-tube baby in the mainland, Zheng Mengzhu, not only became a doctor of the Beijing Third Hospital, but also naturally conceived a male baby in 2019, which is the first in mainland China. "Test tube baby second generation baby".
Misunderstanding 3: Test tube must be the third generation, because the third generation technology is better than the first and second generation.
The first-, second-, and third-generation test-tube babies are suitable for different situations and for different groups of people: the first-generation test tube refers to in vitro fertilization-embryo transfer technology, which takes sperm and eggs from the body of both men and women, and combines them in the laboratory Embryos are formed, and then transferred to the uterus to implant the embryos. It is suitable for female infertility, such as blocked / removed fallopian tubes, uterine factors, and ovulation disorders. At the same time, the male sperm is normal. The second-generation test tube, intracytoplasmic sperm injection technology, uses a microscopic operating system to inject a single sperm into the egg to fertilize it. The main solution is infertility caused by male factors. The third-generation test tube is called pre-implantation genetic diagnosis (PGD), which refers to the method of taking genetic material for analysis before the embryo transfer to diagnose whether there is abnormality and screening for healthy embryo transfer. It is suitable for infertility or male or female infertility. Preventing the transmission of genetic diseases is a method to achieve eugenics and eugenics. In the end, which generation to choose for test tubes still needs to be examined by a doctor, and scientific advice should be made after making a judgment.
Myth # 4: "Promoting evacuation before making test tubes will cause ovarian damage."
In fact, if it is a regular institution operation, ovulation has little effect on the ovary. Women will have 10 or more follicles mature in a menstrual cycle, but generally only one dominant follicle can mature and release eggs. Others Of follicles will be lost naturally. Hedging just allows those undeveloped follicles to continue to develop, which can be understood as preventing their natural loss, so it will not cause premature ovarian failure due to requesting more eggs.
Myth # 5: "The egg retrieval operation is painful, dangerous, and prone to accidents."
Fact: When choosing a regular medical institution, the operation safety factor is very high. At present, the egg retrieval operation in regular medical institutions can ensure painlessness, the surgical environment and surgical technique are safer and more mature, and the operation time usually does not exceed 30 minutes, which is not much different from ordinary minimally invasive surgery. If you choose an unreliable "private workshop", it is difficult to ensure a sterile environment. Coupled with problems such as inadequate technology and improper operation, dangerous situations such as infection and heavy bleeding are likely to occur during egg retrieval.
Myth 6: "When transplanting, in order to improve the success rate, it is best to transplant a few more."
Fact: There are pros and cons in this process, depending on the specific situation. Although in theory the greater the number of transplants, the higher the success rate. But this will greatly increase the risk of multiple pregnancies, and poor treatment may even endanger the lives of mothers and infants. Therefore, the number of transplants is not based on the patient's wishes, but on the mother's physical condition.
According to the current technology, because the embryos transferred by the third-generation test tube technology are blastocysts cultured for 5-6 days, the development potential is better, and it is easier to implant. .
Myth # 7: "Test tube babies are implanted directly into the uterus, and no ectopic pregnancy will occur."
Fact: IVF also has the possibility of ectopic pregnancy. Although the blastocyst will be implanted directly into the uterus, it is not implanted immediately, and it may continue to swim and find a suitable place to implant. If the implantation position is not in the uterus, it will lead to ectopic pregnancy. Therefore, even if the test-tube baby technique is selected, after pregnancy, it is also necessary to go to the hospital for ultrasound examination between 6-8 weeks of pregnancy to determine whether it is intrauterine pregnancy.
Myth # 8: "After transplantation, you need to rest in bed every day, affecting your normal life."
Fact: Bed-ridden all day has little meaning for embryo implantation. Usually, the doctor will ask to stay in bed for 2 hours after transplantation, but after that, you can resume normal work and life.
Long-term bed rest is easy to cause constipation, and it will also lead to slower blood flow to the limbs and increase the risk of thrombotic diseases. In addition, long-term bed rest is also prone to anxiety and tension, which may affect endocrine, which is not conducive to embryo implantation.
In addition, it is also not recommended to use test strips to test pregnancy prematurely and repeatedly after transplantation, which can easily make the mood excessive. Just follow the doctor's request and go to the hospital for blood test at the prescribed time.
Myth # 9: "Eating more grapefruit after transplantation will help the endometrium grow and increase the success rate."
Fact: There is no scientific basis.
Let ’s not say whether the news that “grapefruit can help endometrial growth” is authoritative and reliable. In fact, there are many factors that affect the success rate of IVF. Age, ovarian function, embryo quality, endometrial conditions, nutrition, etc. are all important factors. one. Perseverance in a single food has little meaning.
Myth # 10: "I have a test tube and I must have a cesarean section when I was born."
Fact: Test-tube babies can also be delivered naturally. Both test-tube babies and naturally conceived babies can be delivered naturally. As long as the doctor ’s assessment shows that the expectant mother ’s birth canal, fertility, mental status, and fetal weight are all eligible for delivery, you can choose to deliver. Written at the end: Indeed, IVF is a constantly evolving and progressive technology, affected by many factors such as age, ovarian function, and uterine environment. Many people do not succeed at once. But it cannot be "demonized" because of this, so that families in need really miss the opportunity to own their own children.
