Embryo implantation in humans. After fertilization the human embryo begins a 4 day long journey down the fallopian tube and into the uterus. When the embryo reaches the blastocyst stage it develops two distinct populations of cells. The outer cell mass,called the trophectoderm, and the inner cell mass.
Soon after implantation occurs, the embryo begins producing human chorionic gonadotropin (HGC), a key pregnancy hormone. HGC is also the hormone that pregnancy tests detect. Implantation can occur anywhere from six to 12 days after ovulation, with it taking an average of about 10 days. However, it can take a couple of days after implantation for the body to produce sufficient levels of HGC for pregnancy tests to measure. Itâs generally recommended that women begin testing for pregnancy approximately 10 to 12 days after ovulation.
