IVF is one of the more commonly used assisted reproduction techniques, and it has been a boon to many infertile couples. Those who know about IVF know that it is a technique that uses artificial means to combine eggs and sperm in a test tube and then take the embryo precursors and transfer them back to the mother. Many people believe that the amazing thing about IVF is that it allows for gender selection, is this really true? It is safe to say that IVF is a new technology that has been a world sensation and has opened up new avenues for the treatment of infertility. However, there are some people who use IVF to choose the sex of their fetus, which is still due to the influence of the patriarchal ideology in China. However, fertility experts have made it clear that IVF is not gender-selective. This is also stipulated by the law in our country. Although IVF technology can theoretically be used for gender identification, you cannot choose the gender at will. IVF technology includes a technique called pre-embryo transfer diagnosis, which allows gender identification, but this technique is mainly used for patients with genetic diseases. To ensure eugenics, genetic and chromosomal examination can be performed on one cell in the embryo, and if the genetic disease is related to gender, the embryo needs to be screened for sexually transmitted diseases to avoid genetic diseases. This test is prohibited in the country if it is done only to have a boy or a girl.
