Humidity for human embryo culture has been raised as essential with advantageous effect on clinical pregnancy and ongoing pregnancy after ICSI compared with a dry incubator. Whether the deleterious effect of dry culture would have an extended effect reaches the live birth rate needs to be examined. This RCT is to examine the effect of dry and humidified culture on live birth rates after ICSI.
