Human blastocyst. Computer artwork of a blastocyst embryo about to implant on the wall of the uterus. A blastocyst is a hollow ball of cells formed by repeated cell division soon after an egg has been fertilized by a sperm cell. This is the first stage of embryonic development. If it successfully implants into the wall of the uterus, it can then develop into a new human baby during pregnancy.
