Abstract: The objective of this study was taken to investigate the effects of different additive of maturation media and sperm pretreatment and activation methods on ICSI embryos. The results showed that the development of ICSI embryos got improving obviously by adding 30 ng/mL EGF in maturation medium(P<0.05),it had no significant effect for ICSI embryos between ultrasonic treatment and microinjection in sperm(P>0.05), and the electro-activation was suitable for ICSI embryos.
