What is maximum time for embryo to implant?

The maximum time for an embryo to implant after fertilization is typically around 6 to 10 days. After fertilization, the embryo travels down the fallopian tube and enters the uterus, where it can implant into the uterine lining. Delayed implantation can occur in some cases, but it generally does not exceed 10 days post-fertilization for successful implantation to take place.
