How long does implantation of embryo take?

The endometrium must be receptive for the embryo to develop. The term “implantation window” refers to this period of the menstrual cycle, which lasts roughly 4 days. The implantation window typically lasts from day 20 to day 24 of the menstrual cycle in women. If fertilization has taken place, the blastocyst will be about 6 or 7 days old at this point and prepared for implantation.

                        However, some women have shifted implantation windows, which can result in unsuccessful implantation and infertility. In essence, implantation happens at a precise point in the menstrual cycle when the endometrium undergoes a hormonally-induced transformation from a non-receptive to a receptive state, and the embryo and endometrium are in synchrony.
