A single cycle of 3rd generation IVF costs$40-60,000. If fewer eggs are retrieved and no embryos are selected for transfer, it may take 2-3 cycles, for a total cost of about$100,000. Third generation IVF, also called pre-implantation genetic diagnosis, is mainly for people with genetic disorders that have chromosomal abnormalities or disease-causing genes. The third generation IVF is based on the first and second generation, so ovulation should be promoted first, and after the follicles are mature and eggs are retrieved, the second generation, i.e. single sperm follicular plasma microinjection, should be done, and then embryos are formed, cultured into blastocysts and biopsied, and embryos without chromosomal abnormalities or abnormal genes are selected for intrauterine transfer to block the transmission of genetic diseases to the offspring, which requires many embryos and costs about 100,000 RMB.
