How much do IVF know about infertility

At present, there are nearly 100 million search records on Baidu.

On the one hand, a considerable group in our country is facing the problem of infertility. On the other hand, authoritative information is not obtained smoothly and the information on the network is mixed.

Infertility belongs to reproductive medicine, It first existed in obstetrics and gynecology, With the development of disciplines and clinical needs, Many hospitals have already divided reproductive medicine into a separate specialty. In general large hospitals and general hospitals, infertility can be seen in reproductive centers or reproductive medicine departments. The following are some knowledge points about infertility treatment. We must first understand the right things and then distinguish what from being incorrect.

Not all infertile patients need IVF

The causes of infertility are very complex and can be broadly divided into four categories: male factors (about 30%-40%), female factors (about 40%), common factors of husband and wife (about 20%) and unknown causes (5%-10%).

Generally, the diagnosis and treatment of infertility recommend both husband and wife to see a doctor together. After some examinations, coupled with the doctor’s judgment, whether to do test tubes or not should let the doctor judge whether the symbol does not conform to the [test tube baby indication].

IVF is not what you want to do, The doctor will do it. Admittedly, Some countries do IVF, It’s all up to one’s own wishes. However, at present, the laws and regulations on IVF in China are still relatively strict. Cases in reproductive centers, Have to withstand the examination of [higher authorities]. Some relatively large reproductive centers in China have annual outpatient visits of 100,000 people, and the number of IVF operations is generally around 3,000. You see, not all treatment for infertility requires [IVF].

However, it is not difficult to understand that so many people are flocking to IVF technology. IVF technology has an obvious advantage. Is the effect is faster. For example, after dredging fallopian tubes, Try natural pregnancy. Current clinical studies have confirmed that women’s age is closely related to infertility, and laboratories have also concluded that the older the woman, the worse the egg quality. It is understandable that some people choose to conceive through IVF to be on the safe side. Some organizations believe that the older the woman is also an indication of [IVF].

Legal, authentic and valid certificates must be provided for the treatment of infertility.

This [valid certificate] is commonly known as [three certificates], including ID card, marriage certificate and birth certificate.

This is the specific provisions of < < Measures for the Administration of Human Assisted Reproductive Technology > >. The implementation of these provisions is a necessary process for the reproductive center, and providing real and effective certificates is also a guarantee for the rights and interests of patients. If the patient provides false certificates, the treatment will be terminated after verification and fraud.

IVF Technology Has Entry Threshold,

When treating infertility, if the doctor recommends IVF technology, it is necessary to check whether the doctor and his institution are qualified to carry out this technology.

To develop IVF technology, an application must be submitted to the Health Planning Commission. At present, the Health Planning Commission has approved 356 units nationwide to be qualified to develop human assisted reproductive technology. At present, at least two hospitals in every province in China except Tibet are qualified to develop IVF technology.

The inquiry is very simple. Go to the official website of the Health Planning Commission search for [Assisted Reproduction] to find the specific information of the 356 institutions. If the institution that provides treatment to you is not on the list, but recommends you to do IVF in the institution, then you should be careful.

Careful Use of [Second Generation IVF Technology]

The so-called [second generation test-tube baby] is intracytoplasmic sperm injection (ICSI), which is the artificial injection of sperm into egg cells.

Compared with the first generation of IVF technology, the second generation of IVF is not a technical upgrade, but a new treatment method designed for different causes of infertility.

The purpose of both is to fertilize the egg in vitro. The difference is that the first generation of technology is to put the egg and a certain number of sperm together to provide them with a suitable environment and rely on the sperm itself to complete the fertilization process. The second generation technology is to inject an artificially selected sperm into the egg with the aid of equipment to complete fertilization.

The second generation technology is harmful to eggs. At present, there is no definite evidence to show what kind of harm this method will cause to offspring, but most embryologists tend to use this technology cautiously.

However, there is no need to worry too much about the damage to eggs caused by the second generation IVF technology. Millions of offspring can already be born through this technology. The fertilization method of the first generation of IVF technology sometimes resulted in multiple sperm drilling into the egg at the same time to complete fertilization. Or not fertilizing. One of the remarkable advantages of the second generation technology is that it increases the number of [available embryos]. Therefore, the specific fertilization method, or the method of using half of each egg with the two technologies, depends on the judgment of the attending doctor.

The propaganda that [can increase the probability of twins or even triplets] is incorrect.

IVF technology can indeed increase the proportion of multiple births, At present, the proportion of natural multiple births is about 2-3%, The proportion of multiple pregnancies through IVF is about 20%. The reason for the high rate of multiple pregnancies in IVF is that technicians transplant 2-3 embryos at a time to ensure the pregnancy rate. Sometimes, several embryos live in the uterus at the same time, resulting in multiple pregnancies. However, some organizations advertise [can have multiple pregnancies], which…

In addition, I have to remind that the complications during pregnancy and childbirth of pregnant women with multiple pregnancies are much more serious than those with single pregnancies.

It is illegal for non-medical IVF sex selection technology.

The principle used to identify the sex of IVF is to take out some cells of the embryo during the embryonic period and identify them with molecular technology to see if the embryo contains some sex-related genes to determine the sex of the embryo.

Transplanting embryos of a specific sex into the uterus to give birth to offspring identified by sex is usually done to avoid some genetic diseases related to sex being passed on to offspring. The so-called [non-medical needs] sex selection is to choose the sex of IVF according to one’s own preferences. At present, this is forbidden in our country.

No more than 3 embryos in one [embryo transfer cycle]

[Embryo transfer cycle] refers to the preparation that begins before the embryo is placed, After embryo selection, single or several times into the uterus within two or three days, waiting for 14 days, testing the blood and urine hCG content related to pregnancy until the test results are obtained. If hCG shows abnormal increase during pregnancy, it can be declared [biochemical pregnancy], that is, from a biochemical point of view, it can be considered that the person is pregnant.

The total number of embryos transferred per cycle shall not exceed 3. If there are multiple embryos, the fetus reduction operation shall be carried out according to the doctor’s judgment.

The number of embryos transferred by women under 35 in the first assisted pregnancy cycle shall not exceed 2. This is the specific requirement of the technical specifications of the Health and Planning Commission. This requirement is to limit some assisted reproductive institutions and prevent them from damaging the rights and interests of patients by pursuing the so-called pregnancy rate.

At present, the current IVF technology cannot solve all the problems of infertility.

IVF cannot solve all infertility problems, such as azoospermia and empty follicle syndrome. At this time, sperm supply and egg supply should be considered.

However, please note that at present, China stipulates that all forms of surrogacy are illegal.
