unhealthy embryos. Embryos that show normal development are biopsied with micromanipulation techniques involving the use of very fine glass needles and tools under microscopic observation and control to obtain sufficient cells (blastomeres) for analysis. Based on animal experiments as well as 10 years of experience with PGD in humans‚ including over 200 normal births‚ it is felt that removal of small numbers of cells is unlikely to affect the continued development of a healthy embryo and foetus
