Embryo implantation is the process where a blastocyst attaches and invades the uterine endometrium in placental animals, occurring between the 6th and 12th days post-fertilization. Key biological factors involved include various proteins and genes that facilitate blastocyst development and attachment. The process encompasses stages such as cleavage, blastulation, and hatching.
