This is a clich é d topic. Many families who are new to assisted reproduction may have questions. What are the technical differences between the first generation, second generation, and third generation IVF? Is higher algebra better? Which is more suitable? This is Bao Yun International for science popularization.

The first generation in vitro fertilization (IVF) technology refers to the technique of mixing a patient's egg and sperm in a culture dish to fertilize the egg, and then transferring the embryo produced by the IVF egg into the patient's uterus. IVF, also known as conventional IVF, is mainly used for female infertility symptoms.

The second generation in vitro fertilization (ICSI) technology, also known as ICSI, is a micro fertilization technique developed on the basis of in vitro fertilization embryo transfer (IVF-ET). It aims to assist pregnancy by directly injecting sperm into the cytoplasm of oocytes, mainly targeting male infertility.

The third generation in vitro fertilization (IVF) technology, also known as pre implantation genetic diagnosis/screening (PGD/PGS), refers to the method of analyzing the genetic material of embryos before IVF embryo transfer, diagnosing whether there are abnormalities, screening for healthy embryo transfer, and preventing the spread of genetic diseases.

There are no absolute advantages or disadvantages in the application of the first, second, and third generation IVF technologies. Each generation of technology has its own applicable symptoms, forming a very mature treatment system. The specific treatment plan depends on the patient's physical condition, age, genetic disease and other factors, and assisted reproductive doctors will customize the treatment plan for the patient.

These three costs are the costs of the first generation of test tubes, respectively
