In fertility centers, doctors often encounter couples who make a lot of jokes during pregnancy preparations in order to have a baby. Weng Zhiwei, the attending physician at the Reproductive Center of the First Affiliated Hospital of Guangzhou University of Chinese Medicine, told reporters about common misunderstandings in clinical pregnancy preparation.
Misunderstanding 1: In order to improve the hit rate, people are created every night
In order to achieve their careers as soon as possible, some young couples make babies every night. They mistakenly believe that this will improve their hit rate. As we all know, pregnancy is conditional.
Weng Zhiwei\’s attending physician said that only when a woman has sex during ovulation can the sperm have a chance to see the egg, and only when the sperm and egg meet can conception occur. Not having sex during ovulation is like the Cowherd and the Weaver Girl meeting each other on Chinese Valentine\’s Day. If the Cowherd doesn\’t come or the Weaver Girl breaks the contract, there will be no chance for them to meet. It is futile to create people every night. The end result is that the fields are not plowed well and the cows are exhausted.
Misunderstanding 2: Replenish energy and expect success in battle
Since it was not appropriate to create humans every night, someone had an idea and thought of recharging his energy in the hope of a successful battle. Science tells us that’s not possible either. According to the attending physician of the Weng Zhiwei Committee, a male spermatogenic cycle takes about 90 days. After the sperm matures, it is stored in the seminal vesicle. If adults do not have sexual activity for a long time, they will have the physiological phenomenon of \”overflowing with semen\”.
If there is no spermatorrhea, the human body will also start the mechanism of swallowing or self-degrading sperm. The quality of these swallowed or self-degraded sperm will be greatly reduced, and the chance of fertilization will also be greatly reduced, which will ultimately affect pregnancy. Therefore, doctors often joke with patients that if they hold it in for so long, the tadpole will turn into a frog and will no longer have the effect of a tadpole.
Myth 3: If the sperm deformity rate is too high, you will get pregnant with a deformed baby
Now the concept of eugenics and eugenics has been deeply rooted in the hearts of the people. Many people go to the hospital to check the quality of tadpoles before getting pregnant, but they collapse after getting the inspection report. The abnormal sperm rate is over 96%! If an expectant mother quits smoking, what should she do if she gives birth to a baby with such a high deformity rate?
An increase in the rate of sperm deformities will increase the difficulty of natural conception, but sperm deformities are not necessarily related to the birth of deformed offspring. Dr. Weng Zhiwei, the attending physician of the Committee, said that just as a person\’s appearance is not directly related to a person\’s essence, good looks do not necessarily represent a person\’s health. If there is a problem, it can lead to deformity of the child or stillbirth and miscarriage. Sperm abnormalities are not necessarily related to the birth of deformed offspring.
Whenever he meets a woman who raises this question, Weng Zhiwei\’s attending physician often jokes: If Andy Lau\’s appearance is used as a standard, then most Chinese men are deformed. In fact, what we want is Sun Yang\’s function.
What really affects the outcome of embryonic pregnancy is the DNA fragment of the sperm. If you are really worried about miscarriage, fetal arrest or teratogenesis, you can do sperm DNA fragmentation testing.
Myth 4: Women’s repeated miscarriages have nothing to do with men
Female patients with recurrent miscarriages are often encountered in outpatient clinics. Some men believe that miscarriage has nothing to do with a woman\’s pregnancy. In fact, many clinical abortions are related to male tadpole quality, chromosomal abnormalities, specific infections, etc. From a fertility perspective, seed quality is very important. Weng Zhiwei, the attending physician, said that if the seeds are of good quality, welcoming pine trees can grow on the cliffs!
Myth 5: The man has a history of childbearing, and secondary infertility has nothing to do with the man
Many men try unsuccessfully to conceive a second child. They will blame it on their wife\’s fertility problems, due to the fact that they have given birth to children before. This is wrong. The so-called heroes do not mention the courage of the past. Dr. Weng has encountered many such patients in his outpatient clinic. The woman\’s multiple tests were normal, but the man\’s final test revealed that he had no sperm. This situation is very common. Some men who had a history of childbirth were later infected with reproductive tract inflammation such as mycoplasma, chlamydia or gonorrhea, resulting in obstruction of the vas deferens, ejaculatory ducts, etc., and the sperm could not be discharged, resulting in obstructive azoospermia. Therefore, experts suggest that if pregnancy preparation is unsuccessful, it is recommended to check the man first.
Myth 6: The third generation is the first choice for IVF
Some people mistakenly believe that third-generation test tubes are superior to first-generation test tubes and second-generation test tubes. They mistakenly equate assisted reproductive technology with buying an iPhone because the iPhone 11 is definitely better than the iPhone 5, while assisted reproductive technology is just the opposite. What we often call first-generation test-tube babies refers to separating sperm and eggs, placing them in a container, allowing them to combine freely, and then transplanting them into the mother\’s uterus, similar to what we call free love; second-generation test-tube babies The baby is directly injected into the egg with a single sperm, and then transplanted into the mother\’s uterus after fertilization. This approach is similar to forced marriage; the third-generation IVF is based on the second-generation IVF, and carries out genetic diagnosis to exclude embryos with genetic defects, which is quite Regarding forced marriage + trial marriage, in fact, the higher the level of IVF, the worse the fertility. Only by respecting the \”degradation principle\” of medicine can we better prepare for pregnancy scientifically.
Misunderstanding 7: I just want to make up a good word for assisted reproduction and assisted pregnancy
During assisted reproduction, patients will make various requests. For example, doctor, we want to have twins, can the doctor help us transplant a male embryo? Doctor, we have already given birth to a boy, can he help me transplant a female embryo? This idea is beautiful, but reality does not allow it. The law clearly stipulates that assisted pregnancy for the purpose of gender selection is not allowed. Therefore, Dr. Weng Zhiwei often says with a smile, \”Boys and girls are the same, otherwise my son will have no partner.\”
