Abstract
Growth rates of human preimplantation embryos fertilized in vitro were assessed and compared to the sex of the pregnancy outcome. The likeli hood of a liveborn male was significantly greater than that of a femal e if the mean number of cells/embryo was four or greater at the schedu led time of transfer (odds ratio of 6:1). This finding suggested that the Y chromosome expresses factors which influence embryonic growth ra tes immediately after fertilization.
