IMPLANTATION -

  • Attachement of blastocyst on the endometrium of the uterus is called implantation.
  • Generally it occurs 7th day after fertilisation. (6-10 days). Blastocyst comes close to endometrial wall.
  • Soon the endometrium around the embryo shows the first sign of a decidual cells reaction (DCR).
  • Area of contact becomes more vescular. Implantation is under control of estrogen & progesteron.
  • Implantation is interstitial type i.e. embryo is buried in the uterine wall.
