The features of 3G IVF technology include basically painless egg retrieval, selection of high quality sperm and genetic screening. 1. Egg retrieval is basically painless: during egg retrieval, the anesthesiologist will match the dosage of anesthetics according to the height and weight of the patient as well as her response to the drugs, so that the woman will not feel any pain during the egg retrieval, and at the same time, it can ensure that the quality of the eggs is safe. 2. High-quality sperm can be selected: For patients with azoospermia, the testicular micropuncture technique can be used to search for high-quality sperm in the testes or the vas deferens, and fertilization can be accomplished with the help of monosperm injection. 3. Genetic screening: After the embryos are cultured, they need to be tested and qualified before they are placed in the woman’s uterus for conception. IVF implantation is a procedure that is more likely to fail, so it is important to choose a regular hospital for treatment.
