Implantation is the attachment of the blastocyst to the uterine lining, which occurs in the uterus. The morula is the stage of early embryonic development that precedes the blastocyst, so it is not responsible for implantation. Implantation does not occur within the fallopian tubes or oviducts, although fertilization does. Implantation also does not occur within the ovaries.
