A lot of infertility families who have just been exposed to three generations of test tubes may not understand the test tube technology, and may still mistakenly stay on artificial insemination or in vitro fertilization, in fact, this is incomplete, the technology of test tubes has evolved so far, there have been specific partitions, including a generation of technology, second generation technology and three generations of technology, are for different groups of reproductive aids, and then let Hengjian overseas to give you a detailed description of these technical differences.
First, a generation of test tube technology
A generation of test tubes refers to a generation of assisted reproductive technology test tubes that mix the patient's eggs and sperm in a petri dish to fertilize the eggs, and then transfer the embryos produced by the fertilized eggs in vitro culture to the patient's uterus, also known as conventional test tubes, that is, IVF-ET. A generation of IVF technology is mainly an assisted reproductive technology researched for female infertility.
Second, the second generation of test tube technology
Second-generation test tube technology, also known as oocyte cytoplasmic single sperm microinjection (ICSI), is a micro-fertilization technology developed on the basis of in vitro fertilization - embryo transfer (IVF-ET), by directly injecting sperm into the cytoplasm of oocytes to achieve the purpose of fertility, the second generation of ivy tube technology is mainly for male infertility research out of the assisted fertility technology.
Third, three generations of test tube technology
The technique of three-generation test tubes, also known as preimplantation genetic diagnosis/screening (PGD/PGS), refers to the method of taking the genetic material of the embryo for analysis before the embryo transfer of IVF-ET, diagnosing whether there is abnormality, screening healthy embryo transfer, and preventing the transmission of genetic diseases.
In Jane's terms, one generation is for female infertility, the second generation is for male infertility, and the third generation is based on the first and second generations, plus a technology called genetic screening, so the three generations are suitable for both ordinary infertility families, families with family genetic problems and elderly birth couples.
At present, in the country to the first and second generation of test tube technology is more common, and the three generations of the time is not too long, generally in large cities or second and third-tier cities can also do, domestic infertility families in the choice of test tube technology, according to their own situation, the corresponding choice of technology is also different.
Therefore, after understanding the technical differences, you still have to listen to the doctor's advice and choose the test tube technology that suits you.
