The third generation IVF technology must check the genes, if you do not want to check the genes, you can choose the first generation IVF technology or the second generation IVF technology according to your own situation. The third generation IVF technology is mainly applicable to patients with high-risk genetic diseases to maximize the possibility of discharging diseases caused by chromosomal abnormalities and other reasons, therefore, the third generation IVF requires genetic testing of embryos. While the first generation of IVF technology is applicable to female infertility due to tubal diseases and other causes, the second generation of IVF technology is mainly used for male infertility due to sperm diseases. The choice of IVF should be made under the guidance of professional doctors according to the causes of infertility of both partners, and it is not necessarily that the third generation is better than the second generation. If there is no high-risk genetic disease, then other means of IVF can be chosen according to the situation, and genetic testing is not required.
